As was expected, the Samsung Galaxy S6 is another industry leading flagship smartphone, packing in some of the latest and greatest pieces of mobile tech. This time though, Samsung has opted to exclusively use its in-house Exynos 7420 SoC, rather than a Qualcomm processor as it has done in previous years. So, let’s delve into the specifics to see why Samsung has so much confidence in its latest SoC.

One of the Exynos 7420’s big talking points has been the move down to a 14nm FinFET manufacturing process, which puts Samsung ahead of Qualcomm’s 20nm Snapdragon 810. When it comes to manufacturing size, smaller numbers are better, as shorter transistor distances consume less energy and boost processing speeds. However, smaller, closely packed transistors can lead to current leakage between parts of the chip, an issue that FinFET manufacturing addresses by enclosing the conducting channel in a thin silicon “fin”.

For the same processor design, lower power consumption means more heat headroom for increasing clock speeds or additional battery savings, which will help explain some of the capabilities of Samsung’s chip as we dive down deeper.

The bulk of the Exynos 7420’s processing components are rather familiar. It is built from ARM’s reference Cortex-A57 and A53 CPU cores and its Mali-T760 GPU technology. At a quick glance, the design is very similar to the Galaxy Note 4’s Exynos 5433 chip.

Samsung is using ARM’s high-end octa-core Cortex-A57 and A53 big.LITTLE configuration for an efficient balance between peak performance, using the Cortex-A57s, and energy efficiency, by delegating background tasks to the low power Cortex-A53s. Samsung has again implemented Global Task Scheduling with this chip, which enables the use of eight cores at the same time, as well as dynamic core voltage and frequency switching.

The Exynos 7420 also implements ARM’s AArch64 64-bit execution state, while the Exynos 5433 will likely only ever use AArch32 (32-bit mode), even though it uses ARMv8-A CPU components.

While 64-bit app support is slowly gaining momentum, Android Lollipop’s ART runtime is optimized for 64-bit processors and so should result in a few performance benefits for the 7420 too, depending on the situation. For example, all pure Java apps receive instant benefits from ART’s 64-bit optimizations.

Thanks to the smaller manufacturing process, Samsung has been able to up its clock speeds by 200MHz on the CPU side and by 72MHz on the GPU side, working out to around a very rough 10 percent increase over the Exynos 5433. While this will inevitably lead to some performance gains, the biggest changes have been made to the SoC’s memory and GPU specifications.

The Exynos 7420 is Samsung’s first SoC with LPDDR4 memory, which runs in a 32-bit dual-channel configuration with a clock speed of 1552MHz. Peak bandwidth reaches 25.6 GB/s.

The GPU is where Samsung has implemented the largest performance gains-over the Exynos 5 series.

This already adds up to tangible improvements so far, but the GPU is where Samsung has implemented the largest performance gains-over the Exynos 5 series. As well as the clock speed increase, Samsung has scaled up the number of GPU cores from six in the Note 4 to eight in the Galaxy S6. This extra graphics grunt will come in handy when gaming on the Galaxy S6’s QHD display, and the smaller 14nm manufacturing size has also allowed Samsung to drop the GPU voltage by between 200 and 300 mV at 700MHz. Samsung states that the move to 14nm reduces power consumption by 35 percent and much of that saving looks to have been pumped back into the two additional GPU cores.

Comparing our Galaxy S6 AnTuTu test against the Galaxy Note 4 (SM-N910C), we see a rather substantial increase when it comes to 3D graphics performance at 2560×1440. Benchmarks don’t indicate real world performance differentials, but it certainly confirm the areas in which Samsung has managed to make improvements. RAM speed also sees a decent performance gain from the move to LPDDR4 and AnTuTu also registers a favorable boost to the CPU’s capabilities too, due to the smaller die size and higher clock speeds.

With performance up and energy consumption down, Samsung’s push for 14nm has clearly paid off and it is clear why the company chose to drop Qualcomm’s Snapdragon series this generation. Although CPU performance is only marginally better than some existing flagships, additional GPU performance and battery savings are precious improvements for Samsung’s QHD Galaxy S6.

The Exynos 7420 will likely remain a top performer throughout 2015, as Qualcomm is not looking to reach sub-20nm until end of the 2015.

    The only way I’d buy one of these S6′ is being equipped with a Qualcomm SoC. Screw Exynos. Nothing but junk.

    • SamsungGalaxyExpert

      How The Fuck Is This Junk? Suck My Ass Low – Life Lower Lol People Today Are Mentally Retarded, Hey Guess What? Snapdragon Is Junk Cause This Processor Blows Snapdragon Away

    • Manley Christopher Beasley

      What an idiotic statement. Seriously dumb.

      • Marty

        It’s based on experience. I have a boatload of Qualcomm-equipped devices that all work pleasingly and well. I have a minimum of Samsung-made SoC-equipped devices and they all suffer from lag, stutters and poor performance…especially when opening apps.

        You may worship Samsung, but I say @#$% Samsung. The only way Samsung can make a decent Processor is if Apple shows them how.

        • abhish3k

          Some experience… Anyways dude, just wait for the review then…

          • Marty

            Don’t need to wait for the reviews. Samsung has been making processors for a long time and each and every version people say the same thing – they’ll blow everyone else away – and each and every time they turn out to be crap. The web is full of reviews saying so. This new Samsung processor is bound to be the same crap based on their history.

          • abhish3k

            Don’t just keep reading random crap from the web. They are no better than you. Always trust reputable sources. Wait for AnandTech’s or AA’s or Android Police’s review.

          • Marty

            I don’t just trust them. I experience what they say.

        • Manley Christopher Beasley

          No its idiotic ignorance. I’ve actually never used a Samsung phone with an exynos chip. I’ve ONLY used Qualcomm in every phone I’ve owned. But facts are facts. This exynos chip is quite a bit better than the Qualcomm 810 in both performance and energy consumption. Please stop talking about things you don’t know anything about. That’s called being a troll.

          • Magnus100

            You’ve not used Exynos devices, but Marty has, yet you think you know better than he does about how crappy Exynos is?
            While I don’t agree with everything Marty has said so far, it’s also my experience than every single Exynos device I own lags like a banshee, whereas every Qualcomm equipped device operates smoothly.

            I belive Samsung finally got it right with the Exynos 7 in the Galaxy S6 but we’ll see.

          • Manley Christopher Beasley

            Who says I haven’t used exynos devices? I’ve used them quite a bit. I said I don’t own them. And who cares if I’ve owned them or not? That says nothing about the stupidity of Marty’s statement. It’s illogical to argue from limited personal experience to general truth. It’s even more illogical to argue from no experience to truth. Neither Marty, you or me have ever used this new processor but everyone who has used it and have benchmarked it have given it rave reviews. By definition I am not arguing from bias but you guys are. That’s really idiotic.

          • Marty

            “Neither Marty, you or me have ever used this new processor”

            Enough said. You’re a Samsung ass-kisser.

            “By definition I am not arguing from bias but you guys are.”

            Rethink that definition. You are *only* biased. You have never used the item you are praising. That makes you biased when you say it works well…especially given Samsung’s history. I’m not biased when I believe the new Exynos will be junk because of Samsung’s history. Until Samsung proves otherwise, their chips are junk.

          • Pieter Uys

            Go say that to his face. Oh of course, you can’t, you’re digital crusader. Very tough online, aren’t you?

          • Marty

            You want me to say it in person? Okay. But unless you have something constructive to add to the issue, I’m going to ignore you and people who respond like you.

            And, no, that isn’t me. I have no idea who that is either. A Google image.

          • Aris Routis

            S2 does not lag neither note 2 and both are on exynos

        • This guy just a Samsung basher, pay him no mind..

          • Marty

            Samsung basher? So when I say I love all of my Samsung devices that happen to be equipped with Qualcomm chips, I’m a Samsung basher? Or is it that when I love 90% of Samsung products and report on my bad experience with 20% of them, I’m a Samsung basher?

            Am I a Samsung lover when I have only 100% praise for Samsung? Or can I love properly working Samsung products and hate improperly working Samsung products? What if I praise 99 Samsung products and criticize 1, am I a Samsung basher?

          • I’m just so use to the Samsung bashing I’m putting blankets on everybody. lol. No seriously I never read any other of your comments to see your views on Samsung.

          • Marty

            The properly working Samsung products I have, I love. I especially love my newest acquisition, a Galaxy Note 3. Samsung can make some exquisite products when they aren’t hampered by cooperate red tape or bureaucracy. It took severe financial problems for Samsung to manage to create the S6. The S6 looks to be done right. And I’ll be in line for one. Undecided whether to get the Edge or normal one. If I get the Edge, the Green one is it. If the normal one, the blue one is it.

          • sue

            You are thinking exactly like me with the colors though im more likely to buy the s6 because i think the edge is a gimmick

          • reason

            They Hate Us Cause They Ain’t Us

        • Agent Awesome

          I think you are talking about the Exynos 5 series. Yes, they are sucks and the SD 801 is so much better than them. But last year Exynos 5430 and 5433 were great SoCs. Anandtech has given a very positive conclusion about the Exynos 5433 in their review. The only issue on Exynos 5433 is poor LTE support and it doesn’t have an integrated LTE modem. Except that it’s a perfect SoC. I’m not sure whether the Exynos 7420 has an integrated modem. So far, I have never seen anyone complain about any lagging or overheating issue on the Galaxy S6.

          According to the Anandtech review about the LG Flex 2, they have mentioned that it has an aggressive throttling issue. Now the HTC M9 also faces the similar issue. Surely the SD 810 has a heavy throttling issue.

          https://androidheadlines.com/2015/03/overheating-warning-pops-htc-one-m9-running-antutu-benchmark-app-mwc.html

          Anyway, the Exynos 7420 is superior to the Snapdragon 810, we should accept that. Hopefully the Snapdragon 820 is could be awesome. Samsung is giving a very tight competition to Qualcomm. We should appreciate it.

          • VerlandersPhone

            You FOOL! Using FACTS… in the face of RHETORIC… YOU’RE PATHETIC!!!!

          • Marty

            Fact? I’ll give you a fact. Samsung has never released a better chip. That’s a fact. You might say the *future* Exynos that’s about to come out is better, but that doesn’t change the *fact* that Samsung has yet to release a better chip.

          • Orion4tech

            Well prove that fact then.

          • Marty

            Read the web. Look at all the reviews on the web.

          • Orion4tech

            So you can’t.

          • Marty

            I’d like to think so about this version Exynos being better. And yes, some of my experience is with Exynos 5 – the Exynos 5 Octa 5420 in my Note Pro 12.2. I also have experienced other Exynos-equipped devices that have similar issues. Every year, it seems, when a new Exynos version is about to be released, the Samsung fanboys *super*-hype it up like it’s going to be a GOD among chips. And each time it proves to be junk compared to Qualcomm.

            Until Samsung has proven to be better, their history will haunt them.

          • Orion4tech

            I doubt you are saying the truth, also you gave 0 specifics.

          • guest qwe

            LG has consistently had throttling issues, and now it sounds like that will be compounded by the S810’s own heat issues. I’m not impressed thus far from what I’ve seen form the S810.

        • cpaixao

          how can you blame processor for this… it looks like you don’t know anything about processing at all.

          • Marty

            What else could it be? The device is equipped with a Samsung chip. It lags and stutters. Who gives a rats ass what else it could be when the very same device equipped with a Qualcomm chip doesn’t lag and stutter. Whatever the fault is, it’s associated with the Samsung components.

          • cpaixao

            I’ll not feed you, Mr. Troll.

        • ignoranceisbliss

          You do realize Samsung provides the chips in the Apple devices…. Right?

          • Marty

            I was wondering when someone was going to bring that up. I hope you understand that Samsung doesn’t design the Apple chips, but only manufactures them for Apple. Apple designs the chips. And Apple has extensive history with ARM, long before Samsung was even a skidmark on the web.

          • John Kar

            Yes, a simple design with 2 enlarged cores that has the total power of a SnapDragon 801.

            Designing a processor isn’t hard, nor is it something you should be proud of.
            Samsung’s problem came from designing a proper algorithm with big.LITTLE, which they fixed with the 5433.

          • Marty

            Yeah, I’ve read that before. It still doesn’t absolve them from producing products that perform undesirably.

            “Designing a processor isn’t hard, nor is it something you should be proud of.”

            If it isn’t hard, what’s that say about Samsung? If Apple and Qualcomm can get it right, what about Samsung? And I never said I was proud. You imagined that in you own skewed way.

          • Orion4tech

            Samsung is primarily a manufacturer when Qualcomm and Apple are not. If Samsung will want to get into the chip designing business their competitors will have serious problems, like TSMC has right now.

        • Sam

          Lots of QC employees and stock holders crying foul…

        • ConCal

          Samsung is my least favorite smartphone maker, but you are completely wrong. You clearly understand very little about processors.

          • Marty

            You seem to be misunderstanding what I’m saying about Samsung. I’m saying from my experience with Samsung chip-equipped devices that Samsung isn’t likely going to change with just another new chip. It’ll probably suck like all the past chips have for usability.

            I can’t be wrong in my experience. I *did* experience 100% of Samsung chip-equipped devices lagging and stuttering. How can I be wrong in that experience? I *experienced* it.

            Whether I’m wrong about this new Exynos chip being just as crappy for smoothness and app-opening speed as all the past Samsung chips have been remains to be seen. And if it turns out the new Exynos chip does work well, I’ll be just as pleased as any one of you.

            And as far as understanding how CPUs work, that doesn’t matter. Whether it’s the CPU or a component associated with the CPU on the die of the *SoC* makes no difference. It could be a memory controller problem, for all I know. But it’s still a Samsung component problem associated with the Samsung chip.

      Im typing this on samsungs galaxy tab s 10.5 tablet.it has an exynos chip in it.i also have an ipad air 2.ive tested them side by side.the ipad air 2 is just a bit faster but dont forget its newer.both are very fast and i havent even gotten rid of any of the bloatware on the tab s thats supposed to slow it down.i also used to have the samsung galaxy note 10.1 tablet from 2012 and that had an exynos chip and it ran very fast.im just telling you my experiences

      • Marty

        The latest gripe I have with this Exynos-equipped Note Pro 12.2 is it won’t play Google Play movies/videos. Everything else I have will play them, but this @#$%^&* refuses to play them. Keeps timing out with a 408 network error message. Nothing wrong with the network either. It will play videos in Netflix, Hulu and every other video streaming apps installed. But it refuses to play Google Play movies/videos. At the same time this @#$%^& won’t play them, my other devices do play them, so it isn’t a Google Play problem.

        I had a Tab S for a few days. Nice Tab, but Samsung’s manufacturing quality control – or lack thereof – showed real bad in it in the form of being bent/warped. Doing my gun-barrel test, I saw *they* (I returned for another and another) were either slightly curved or had a distinct angle in them. And yes, they all exhibited the lag and stutter I’ve always experienced with Samsung chip-equipped devices.

  • abhish3k

    See Sansung haters, that’s innovation. Behind the scenes stuff is all that matters and that’s why I was and am confident with Exynos S6 that it’ll be awesome till (maybe) S820.

    • Although I’m fond of snapdragon, recently they got lazy. Maybe Exynos will be a good wake up call for them.

      • buckley101

        Qualcomm didn’t get lazy. They were designing their own next gen krait cpus 32 bit and got cut in the middle because everyone else had 64 bit cpus. So now they lease ARMs cpus for the time being until next year they’ll go back to their 64 bit krait when it’s ready. They most likely worked their ass off to stop mid way through and get this chip out after switching mid design. Also, while I’m impressed by the xynos soc, I would never sag qualcomm got lazy. They design their own cpu and gpu architectures in house. That’s a shit load of work compared to just leasing arms cpu and gpu architecture and just dropping their designs right in the build (Samsung). Either way, I’m excited about the 820 next year. They’ll have had a year and more to work on it now

        • abhish3k

          They should have anticipated it since the launch of IPhone 6.

          • Nighty

            That’s the whole point. When Apple went 64-bit everyone scrambled to do so too. What happens is that a CPU takes YEARS to design. There wasn’t enough time to complete their in-house design so they had lease ARM’s design. Either that or offer a new 32-bit design with improved performance but without the ARMv8 features and (obviously) no 64-bit. That means it would underperform with ART and encryption and all that.
            They got caught with their pants down yes, but so did everyone else. If anyone else had managed to come out with a custom 64-bit CPU in reaction to Apple’s shift then yeah, bash on them. Otherwise it’s a matter of what technology is available and only Samsung and Intel have FinFet right now that I’m aware of. I doubt they could get access to Intel’s fabs and Samsung… they could but it’s also a question of yields and priority. I’m guessing Apple has got top priority there, then Samsung and THEN whoever else is left. By using 20nm they have more options. They might not perform as well, but they’re still in the same league. Question is how well will they do NEXT year with their custom CPUs and FinFet.

            Also, this is not as bad as back in the Scorpion cortex A8/A9 days when Qualcomm just ramped up the clock speed to compete with A9 in order to tide them over till Krait was ready (but then again they were all based on the same instruction set so it was a more viable solution then). In a good competitive setting it’s good to see companies leapfrogging each other in performance (though it might be disappointing to fans of either company).

            As long as they’re using off-the-shelf parts, the more important questions about Samsung’s SoCs are their choice in other components and what features they choose to support (USB 3.0 vs 2.0, RAM, etc).

            It’ll be interesting to see how well the new flagships perform once actually shipping but it won’t be enough reason to dissuade many users. Most don’t care about the EXACT level of performance of the devices as long as it’s comparable and (more than) good enough. The original M7 had a slower chipset than the S4 (1.7Ghz vs 1.9 and I think the GPU was slower too), same for the M8 and S5 IIRC. That didn’t stop people from buying HTC’s devices. Now it’s going to be 2Ghz vs 2.1 Ghz and comparable GPUs according to preview benchmarks.

            I’ll still get the M9 most likely but it would be nice to see this in a new Note Pro 12.2 (fingers crossed).

          • mobilemann

            samsung’s processor is also ARM’s design, as only Qualcomm and apple are licensed to design arm cores as far as i know!

          • chris pinkston

            is kind of like a8/a9 days. Qualcomm has just been ramping up clock speed on krait for more performance since apple went 64bit. sd801 and 805 are the last of the high clocked 32-bit krait based chips I guess.

          • Sid

            “If anyone else had managed to come out with a custom 64-bit CPU in reaction to Apple’s shift then yeah, bash on them.”

            Don’t forget nVidia’s Denver cores which are also custom AArch64 capable chips and have been in shipping devices since last year.

        • abhish3k

          They should have anticipated it since the launch of IPhone 5s.

          • buckley101

            They should have, you’re right.

        • wiseguy101

          Well.. Samsung is designing their own in-house performance-packed 64 bit CPU as well and that should feature in the Galaxy S7 next year.

          • buckley101

            Lol k. Good thing it’s 64 bit

      • Mehmed

        They are working on SD 820 with finfet, a new 64 bit Kyro CPU and Next Generation Adreno GPU which will go to OEM’s in 4Q2015 and be available starting 1Q2016. But until then The Exynos 7420 is the King.

    • buckley101

      That’s innovation? You realize that Samsung leases all of the hardware in their socs? They don’t design anything except maybe the memory. They lease ARMs / Linaro cpu scheduling algorithms, ARMs cpu architecture (qualcomm usually designs their own), ARMs gpu architecture, and most likely Qualcomms modem software and hardware. They probably design their own memory. Otherwise, they lease everything. The 14nm finfet is their own which is good. It’s still not better than Intel but it is better than TSMC (who qualcomm pays to build their chips). I wouldn’t really call it innovation by any means but rather good work.

      • Orion4tech

        14nm, LPDDR4, UFS 2.0, does this tell you something genius??

        Apple also doesn’t build it’s CPUs, Samsung does it.
        Designing a CPU is not the hardest thing.

        “It’s still not better than Intel”

        That remains to be see.
        Intel launched it’s 14nm at the end of last year with Core M and we barely have products available with this CPU, or with intel’s 14nm Samsung will sell millions of S6’s starting next month. Yeah Samsung’s tech doesn’t look too bad in comparison.

        • buckley101

          Lol why are you angry, there is literally nothing to be mad about.

          1. Like I said: the 14nm process and memory are very impressive.

          2. Yes, I’m aware Apple doesn’t “fabricate” their own CPUs…idk where that came from.

          3. Designing a CPU is not that hard, sure. But making it bleeding edge is incredibly difficult. Why do you think everyone leases ARM cores instead of designing their own? ARM cores are EXTREMELY expensive. If they could just do it themselves they would save millions. It is probably single handedly the hardest task in designing the whole smart phone…maybe hand in hand with modem sw/hw

          4. You must not understand what the 14nm process really means. I’ll just quote from anandtech for you because they explain it better than I could: “Samsung’s 14nm FinFET isn’t comparable to Intel’s 14nm process due to the use of a 20nm metal interconnect, there are some density improvements in areas that aren’t gated by interconnect pitch. While transistors are an area where we can see significant improvements to clock speed and power consumption, the metal interconnects can influence performance as well due to power dissipated by resistance in the interconnects, in addition to limitations on clock speed due to RC delay. This means that Intel continues to hold a significant process lead, as reducing interconnect pitch is exponentially more difficult past the 20nm node as resistance and capacitance issues increase dramatically.”

          Now I understand why you fired back angry. It’s frustrating when you think someone else is stupid because they don’t understand everything you do. Then you comment back pissed off only to find out that you’re the one that doesn’t understand much. Now you know how I feel, except I’m not angry.

          • mobilemann

            He was angry because he construed your argument as supporting a brand he has a distaste for. You can’t say the A word around here.

      • abhish3k

        Good for them. Why fix something that ain’t broke? Right? Even Qualcomm’s S805 heats up more than the Exynos variant (as seen in real world performance, Google it). So, I think they know what they are doing.

        • buckley101

          Yes, I agree. Sammy did a good job with this SoC. A side note, it’s really not a good comparison between the 805 and the 810. The 805 uses Qualcomm’s Krait CPU architecture and the 810 is leasing ARM cores. They’re two totally different animals. “heats up” could also mean cpu or gpu but either way the 805 was never throttled due to heat. Heat wasn’t an issue. Personally, I think the 805 is a better SoC besides memory speeds. ARMs bigLITTLE implementation isn’t near ready. Scheduling algorithms aren’t very good. In real world translation, not bench marks, it’s very hard to tell which core to scheduler a new thread on. You can’t determine how long a thread needs to run for but only that it want to run. Sammy uses ARMs/Linaros scheduling implementation by monitoring power and Qualcomm uses their own by monitoring the size of the thread ready queue. Anandtech proved that Qualcomm’s schedueling algorithm is actually pretty far ahead of ARMs/Linaro’s, but they both need a lot more work. bigLITTLE shouldn’t even be out right now. It’s being used for marketing leverage. It’s not ready

          • abhish3k

            Took me a while to search it. But, the heating and throttling issue existed. See this – http://goo.gl/jB7fE7

            Thanks for the other info.

          • Buk Lau

            ^Exactly, ARM’s implementation of big.LITTLE is very hopefully and optimistic. What you addressed is always my concern, how will the scheduler know what tasks are more demanding and therefore should use higher performance cores? How do they determine the workload without actually running it first in serialized computing? I can see big.LITTLE being very effective in running scheduled background tasks, but in real world app usage I don’t see a strong benefit over just fewer but much higher performing cores like what Apple and Nvidia did with A8 and Denver.

          • Nighty

            It’s used in part due to marketing but more importantly due to the fact that the A15s (and I’m guessing that the same is true for the A57s) draw too much power for smaller tasks. Krait SoCs had good power/performance ratios and tended to have better battery life from what I read. This was most likely due to a mix between the Krait’s performance/power draw and the fact that its cores could each run at their own speed thanks to their asynchronous design. This was one of the few things that seemed good about the old Tegra processors, they had ONE low power core basically for when the device was asleep which is easy to determine.

            I wonder how much Qualcomm will continue working on their scheduling algorithm and if they will still use bigLITTLE in their next chipsets which will use their own CPUs (from what I read in the supposed leaks they appear to be using something like it but with only one type of cores, maybe it’s an approach akin to Tegra’s old one where it was a different manufacturing process for the low power ones.)

        • mobilemann

          the improvement is with standard gains, smaller manufacturing process, means faster, and more efficient, but samsung just makes arm designed cores. Qualcomm and apple design them. Huge difference.

      • Honesty007

        You do know that Apple’s processors in its iPhones and iPads are also built on an ARM architecture right? In other words, they do not design their own chip fully either.

        • buckley101

          I think you’re confused. They lease ARMs instruction set, just as Qualcomm does. They both design their own CPU architecture though.

          Side note: I’m not a fanboy idk where this Apple thing came from

      • fitnesspro22

        Samsung will be a history in five years. Apple too will have hard time. Look at the new, super speedy phones at half the price, Zenphone 2, OnePlus One, among others and don’t underestimate the Chinese made phones. It is the combination of new inexpensive technology and knowledge of the local markets around the world, used by new, lean and aggressive companies. No company is too big to fall.

        • ConCal

          No way, I find that highly unlikely. I guess anything’s possible though.

          • fitnesspro22

            Mark my words. You have got to analyze the new markets and companies. Every big company is like the Roman Empire- it rises and then falls. Besides, the bigger they get, the more expensive and inefficient they become. It is inevitable. We’ll see.

          • ConCal

            I don’t disagree big companies *can* fail. But I feel your assment of Samsung, Apple and the Chinese companies is a bit off.

          • fitnesspro22

            The early indication will be how well or poorly Galaxy 6 etc. sells. My concern is that instead of being itself, Samsung is playing the “Apple” game. Now, that is a risky undertaking. It will never replicate Apple’s current success. Another indication is the Nexus 6 vs Nexus 5 respective success. It is not an accident that the Mighty Google reversed itself and is considering Nexus 5, 2015 with a Chinese phone maker.

          • John Smith

            The problem with your statement is that the Roman Empire never fell. The world is under Vatican ownership.

          • mobilemann

          • John Smith

            Go away stalker, I don’t care for your opinions. You are a liar and coward. Shill a bit more for Apple big nose.

          • mobilemann

            It’s cool, i don’t care for people so incredibly stupid they don’t understand opinion from fact. There is no way to phrase my last comment to make it an opinion.

            And i just use what’s best for me, and actually know what i’m talking about. Sorry we can’t say the same for you, tiny dick.

        • patrik

          Oh wow, you are so wrong. Apple and Samsung are the ONLY companies in the smartphone business who’s actually making money atm. Every other brand is loosing money to stay in the game.

          So please explain, how a company without any earnings, is supposed to make in in the long run?

          • fitnesspro22

            Patric, yours is a fair question. I refer to analysis of the micro economics of the emergent markets. Both Samsung and Apple are busy promoting their flagships in a saturated market place. Both are behemoths, bloated companies, getting more expensive products year after year. Compare that with the new, very efficient smaller competitors, who provide new, advanced devices at about half the price, among them Asus with its new Zenfone 2, OnePlus One and other Cineese companies. The key is in the specific knowledge of and skill in marketing in the new, emerging markets. Without a doubt, the local competors have the edge because no one knows better their markets and consumers. True, both Samsung and Apple have plans for market penetration, however they are too cumbersome and remot to affectively accomplish that. By contrast, the evidence in China is uncontrovertible, showing the success of the new Chinese companies. The only exception I see, is Google, e.g., Nexus 5. Having realized that Nexus 6 is not quite the success Nexus 5 has been, Google is looking into de facto collaboration with the Chinese to launch the next Nexus 5, 2005 reasonably priced. One may look st it from a history’s point of view, the prime example being the rise and fall of the Roman Empire. It us a relentless process that spares neither countries nor companies. It has the specter of inevitability. So, the bigger they are the harder they fall. Naturally, at the end of the day we’ll see. I hope you will find my answer satisfactory, if not entertaining. William P.

            Dude…..are you aware that samsung also makes a lot of low end devices?

            I don’t mean to be necroposting but…Xiaomi is making money, and possibly very much or they wouldn’t have enough cash to burn to expand their lineup so quickly.

        • [email protected]

          Then those new Chinese companies will become big and then they will fall too. I dont get your point. What is new here?

          Samsung mobile phones might get squeezed but since they are a big global player in other critical mobile components such as chip making, mobile DDR4, Nand storage, I doubt they wont survive.

          I think galaxy s6 might sell well.

          • S.Yu

            Actually no…the Chinese President Xi Jin Ping is indiscriminately brainwashing everybody in China.

            You see a ban on any unauthorized(that means every, at the moment) foreign TV drama and Japanese Anime(even though I estimate that at least 80% of the population doesn’t come in contact with those, meaning he’s specifically trying to brainwash elites) lately, and domestically the only drama genre that gets approved without resistance is WWII anti-Japanese. So you get “fairy tales” of “ripping Japanese soldiers in half by hand”(the exclusive term in Chinese:”手撕鬼子”), Japanese POW torture stories, soap drama of soldiers falling in love during the Anti-Japanese War…because the writers couldn’t come up with anything other than these curiosa to attract viewers. Besides that are the 3rd and maybe 4th or even 5th remakes of popular ancient Chinese literature, or fiction on well-known ancient Chinese characters(again due to lack of topics to write on), these get by fairly easily…but as you may have heard, one series barely made a few episodes and then had all the female’s shots cropped from beneath the shoulder because they were dressed “revealingly”(actually everything was covered up except for some cleavage, typical of the Tang dynasty and true to that piece of history it was depicting. Ironically almost nothing else in that story was historically correct). This is generally concluded as: no criticism of the present, because it’s lead by the Communist Party, nothing can go wrong in the future(thus no drama), because the path portrayed by the Communist Party is proper and bright, only the oppressive and all-evil feudal reign of emperors would fail.

            Also all comments on some popular news sites are censored, I mean every one of them is reviewed before visible to others, and may be taken down any time if seen as inappropriate(most swear words are actually let through, as long as they are directed outwards). I’ve already had dozens blocked or taken down because I couldn’t bear some of the extremely ignorant remarks on bashing Samsung or praising “Almighty Huawei”(you can already imagine) and replied to them in a slightly…”passionate” way.

            Also all foreign textbooks are banned from university classes, politically relevant or not, except as extracurricular reading, in the name of “establishing correct values”.

            What I’m saying is that the masses are quickly turning extremely nationalist, and you can guess what impact that has on–in the immediate future–low end, and, in the slightly distant future(because the wealthy are mostly better educated and could think better for themselves and are therefore harder to brainwash, but their kids could be brainwashed)–high end market. The Chinese companies will sell like hotcakes in the world’s largest market without having to have any advantage over foreign companies, while all foreign companies will be having a hard time in the consumer’s market where the act of purchase is swayed heavily by emotional and irrational elements.

      • chris pinkston

        not sure but don’t thin qualcomm lease lease their modems. A way to get people to use their soc because of th ebuilt in modem solution. Think Samsung have their own now.

    • deltatux

      People just mainly hate on Samsung for not releasing the proper sources for their Exynos processors. There’s nothing wrong with the processors themselves.

      • Just_Some_Nobody

        Yup, that’s the main reason people hate on Samsung alright.

      • mobilemann

        they perform worse than their peers. Once others are on 14nm, this will be true again.

        • Алексей Кастевич

          Wrong. Samsung’s Exynos
          SoC have always performed better than Qualcomm ones.

          • mobilemann

            That’s not true at all:)

        • John Smith

          You are a fool. Even above there is a video comparing a previous Snapdragon version against Exynos 5433. Move along now.

          • mobilemann

            you’re a fucking idiot. That’s explained by the die shrink. Go back to the kids table shit dick. They use reference ARM designs, which is also why apple spanks them every year. (they design their own cores)

            I can’t wait for you to reply with a half researched dog shit of a comment about manufacturing vs design.

          • John Smith

            Says the person with poor grammar. Start with a capital letter, thicko. You’re a pussy keyboard warrior, and illiterate TV watcher. You shill for Apple, or you feel embarrassed by your failings in life. Send me your address details stalker and we will see how brave you are.

            Please now tell me where I said they didn’t use ARM designs? Apple doesn’t spank them every year, they were behind last year and they will be this year. Maybe you’re incapable of finding the benchmarks so far for the 8890, even before it’s been fully optimised. The M1 cores are 30% faster than the ARM equivalent from the 7420. The problem with low class, low grade cowards like you, is that you don’t know how to interpret information properly. I owned you once already, and will own you again when the 8890 comes out.

            You are a follower, you probably think 9/11 was real. Don’t attempt to converse with me you nobody. Get back to your processed food diet and TV watching ways. You don’t have a clue about the real world, and stop stalking me on other posts, you fucking low grade pussy. Face me, and we’ll see how brave you are.

    • fitnesspro22

      Yes,may be till it starts leaking

    • mobilemann

      yay for all the kids like you who don’t know the difference between people who design arm processors and people who just use arm reference designs.

    • Dr Dré

      Well 64bit on a smartphone with less than 4GB (when you know that 32bit extended mode was allready able to deal with far more than 4GB) Is purely an useless commercial posture to be able to say “I have one a least as big as Apple’s” When Apple makes something useless, everyone feels like it has to be followed… Allas, they may be right, because the vendor wich will counsel Mrs Smith while choosing a smartphine will surely say “See that one has a 64bit cpu (ok it is complety useless on a smartphone, but they are so much more expessive !), just buy this one !”

      Well since CPU design is driven by two main leverages : high performance for scientific computation and low power consumtion for portable devices, 64 bit smartphone CPU may be just a rationalisation choice between the two.

    • Steve Brain

      Mm, yes innovation. And then they keep Touchwiz which cancels any innovation positivity and adds some extra negativity on top.

  • VerlandersPhone

    John Carmack said the new Exynos Chip is just as good as the Qualcomm chip. He also mentioned that the Exynos actually outperforms the Q810 in certain tests, while at the same time reducing thermal loads. Sounds good to me.

    • Marty

      What’s that have to do with stable and pleasing customer usage – instant-open apps and no lag and such? I don’t give a poop if the Exynos can blow away everything going. If it lags, stutters and doesn’t function well in real-world operation, it’s not worth having. The Qualcomm-branded SoCs do perform well in real-world operation. Screw the numbers, give us good user performance.

      • Yea tell that to the G3 users

        • Marty

          I have a G3. The best smartphone since the HD2. Mine still works amazingly well. And I’ve flashed the crap out of it. But it has a Qualcomm SoC.

          • Marty

            Apologies. I meant GS3. Which is what I thought the person I was responding to meant. The GS3 is more prominent in my mind than the LG G3…

          • jovan1256

            My s3 started lagging after i updated to kitkat. but Thats years ago. I cant judge the chip based on the s3.

          • Marty

            On one example, of course not. But I have many examples of Qualcomm chip-equipped devices performing smoothly and lag-free. However, 100% of the Samsung chip-equipped devices I have and have experienced have exhibited lag, stutter and performance issues. That, I can judge by…along with web reviews saying so.

          • jovan1256

            Ok. Well I cant argue about the experiences you had. If so well by all reports this chip is better. the exynos never won qualcom in tests until now. We have wait and see what happens.

            I only had two samusng devices, S3 and GN4 and the GN4 is a beast running the slower exynos. I could only imagine what the SD805 and 810 would be like

          Hmmm…are you saying the LG G3 exhibits lag and stuttering and is equipped with a Qualcomm chip?

          I have a lot of devices equipped with Qualcomm chips, including an LG G2, but I don’t have the LG G3.

          • Yes I had the G3 and that device was terrible, got rid of it and got the Note 4 couldn’t be more happy. Straying from Samsung was a huge mistake.

      • VerlandersPhone

        I read your post below which is anecdotal nonsense at best. You have no experience with the new Exynos chip. Regardless if the old chip was the worst on the market (which isn’t the case), this is an all new chip. The first 14nm soc on the market, and it’s 64-bit. You’re launching hard against the actual evidence and data with ZERO facts in hand. I don’t have a dog in the fight, other then the fact that I want the best Gear VR experience possible. If John Carmack who actually HAS tested the chip and currently programs for it says it’s better; I’m inclined to believe him. Got it McFly?

            By playing with and using an S6. You think I’m biased. In one way I am. My experience with Samsung chip-equipped devices hasn’t been good. So me not believing Samsung will produce a good experience with their next chip is logical.

        • Marty

          Until I, a common customer, experience better operation with a Samsung-made chip than I have in the past – consistently poor operation, that is – I will be inclined to believe anything new from Samsung will be crap. IF, and that’s a big IF, this new Exynos performs well without lag, stutter and poor app performance, I’ll be among the first who praises it. But like I said, based on experience and this kind of hype happening each and every Exynos version release, it’s bound to be junk.

          • Gepstra

            Do you even know that the software (Touchwiz) is responsible for lag and stutter? Looking at your comments I can see you have a real “all or nothing” mentality, I can tell you that that won’t get you very far.

          • Marty

            Really? So I have TW devices with Qualcomm chips and TW devices with Samsung chips. The Qualcomm-equipped TW devices don’t exhibit the lag and stutter like the Samsung-equipped TW devices.

            Hmmm…must be a Qualcomm problem, huh? How dare Qualcomm make Samsung look bad!

          • jovan1256

            You are full of hot air. What is the latest exynos device you used? I am using the not for now and it is the snappiest phone one can asked for. The only lag on the phone is the recent button and thats because the recent button functions as the options button as well so it waits for you to long press. Hence the apparent lag. But still you are full of hot air!

          • Marty

            “I am using the not for now”

          • Jamie Jukes

            Everything you say about the new Exynos is nonsense I had the Note 3 with Qualcomm SD 800 which lagged and stuttered pretty much all the time. This Exynos chip that is currently in the S6 (Which I have BTW) is most definitely the winner between the 2, so let’s not go on the fact that what you think is correct. This chip currently outperforms any chip currently, yes including “Real-world performance” or what ever you mean. It is the first chip to have this sort of leap in a while since Apple’s new 64-Bit Cyclone Chip. Android took a huge hit in the market when Apple unveiled it’s 64-Bit Iphone 5S, since then Qualcomm has been building slowly to it’s new design but Samsung thought it would be best to stick with it’s in house CPU, yes CPU not instruction set which is ARM. This is all fact. BTW, the S6 I have with the Exynos 7420 has no stuttered once, no crashes and is stable.

            Not really when Im not new to android at all I know how it works and behaves, your the one over your head thinking the 7420 isnt good soo…

      • Marty is stupid

        I have a Tab s 8.4 (exynos 5420) and a note 4 (Snapdragon 805). There is no noticeable difference in the user experience. Yes, the NOTE 4 benchmarks better, but it’s also a newer device. The qualcomm-Samsung partnership has been beneficial to both parties for a number of years, and Samsung has a lot of pressure to succeed here with the S6. They would not have dropped Qualcomm if they didn’t have a much better alternative and it appears they have.

        • Marty

          Until I have a positive experience with a Samsung chip equipped device, I will maintain my view. Proof is the only way I’ll say one way or the other. If the new Exynos proves to be better, then Samsung will have learned a valuable lesson on user experience.

          • Orion4tech

            Who are you exactly??
            All insights show the S6 performing better and most importantly having better thermals that the S810.

    • Guest

      outperforms? It get scores up to 20-40% better then the

  • Alex

    And don’t forget the new memory type they are using on the storage, they the 1 ones to use it to.
    It got read/writes much more superior, and that will improve the SOC performance to.

    • abhish3k

      Yeah, UFS 2.0 memory modules.

  • A very fine chip! But Samsung still won’t release the source! RIP AOSP for S6!

    • abhish3k

      Yeah, that’s also what I am concerned about. :(

      • Anonymousfella

        Theming is about as far as they’ll let you go with the S6. As long as the UI is snappy, I don’t mind that much…

      • I have 0 hopes from them. A device having active development on XDA is how I personally choose my next device. :P

        • n900mixalot

          The Exynos devices actually do have active development on XDA. Give devs a little more credit.

    • For me that’s no concern, I’m so done with these buggy a** always in Beta Roms it’s not even funny. Plus you lose all the good software features from Touchwiz with AOSP biggest one being Image processing for the camera.

      • ConCal

        But touchwiz is so ugly….

        • superspartan100

          They added theming to it so you can change everything about it, more in depth than a downloaded launcher, almost like cyanogenmod. We can finally get rid of the teal :)

      • mobilemann

        why do you think they are buggy? One is related to the other!

        • Roms are never as stable as what comes straight from the factory. It’s always updates because something doesn’t work right or something broke something else. CM has updates everyday. It gets old after a while

  • Aki I.

    What about radios and all the other stuff involved in mobile cpus? I thought this article was taking a look at the processor.

  • Behzad

    it looks like s3

  • sahand

    I expected more from RAM and I/O. But the GPU is amazing!

  • Rick_Deckard

    I kept my S3 for 3 years…. I gotta feeling that I will keep my S6 for more than 4 years…. Time will tell!

    • mobilemann

      my S3 has CM12 (unofficial) on it, and it actually runs really really well, i have to say. It’s my backup phones backup.

  • Redglyph

    Awesome architecture, let’s hope this time it will benefit other countries than Korea.

  • fredphoesh

    What about 24bit 192khz audio?

  • ne potrebno

    sranje!!

  • ConCal

    I hate Samsung’s design but love their innovation. Great job, Sammy!

  • Mehmed

    Since two years I’m hearing Samsung works on its own CPU and GPU. But there is no announcement. Next year they could just use a72&a62 + CCI 500 + Mali t880mp8 + 14nm LPP.
    I really want to know what they are opting for.

  • galaxyNote4isBoss

    At the end of the day Samsung is so far ahead it’s comical. The Exynos 7420 14nm 64bit processor in the Galaxy S6 and S6 Edge are the best in any handset on the market period.

    When the Galaxy Note 5 and Note5Edge or NoteEdge2 arrives in October/November it will have the new Exynos 7890 14nm 64bit processor which will make these handsets BOSS.

    In January 2016 the Galaxy S7 and S7 Edge will have a Exynos 8 64bit 10nm Processor so far ahead of all rest.

  • Paul

    Well what company can say they design and bulid there own processors and there own world beating super amoled screens. Lota hate for samsung, but this company seems to be the only one whos offered up everything there is in the tech industry. 14nm chip 3gb ddr4 ram wireless charging quad screen technology nfc as well as magnetic stripe payments. Seriously the other companys should be running once this gets released, only less educated in the tech world would buy something inferior.

  • fredphoesh

    Does anyone know if this chip does 24bit 192khz audio?
    less lag on note 4 exynos phones than snapdragon… so I reckon somehow exynos prefers touchwiz.

  • James Theodore Retuya

    that exynos chip is beautiful.

  • José Marques

    Very good, step by step, competition is increasing between companies and consumers will benefict from it. Doesn’t matter who does what. In just one decade we have in our hands portable and powerfull phones capable of competing with Pc’s in many, many ways at an affordable price (at least for developed countries). The heating issues as well as bat autonomy are still serious problems to adress.

  • Stealthypepper

    I agree its the processor which is fast but you barely can notice the difference and i prefer note 4 because of its better design and price! S6 is just a piece of shit

  • jamie hicks

    Samsung s6 owner here, soc is stupid fast but battery life could be better. Coming from a z2 with cm11 installed.

    Camera and screen are amazing and software is a million times better.

    Just thought I would leave my input.

    Also first samsung since s3 (had z2, m8, moto x 1st gene one plus one ) I have a phone problem lol

    I would highly recommended this s6 but would have preferred a thicker phone for more screen on time.

  • Mehmed

    Exynos 8 Octa might destroy this. But just if it really has 64 Bit Dual Channel 1600 Mhz.
