Snapdragon 810 vs 805: what to expect from Qualcomm’s next high-end SoC

by: Robert TriggsJanuary 13, 2015

Qualcomm’s new Snapdragon 810 is already powering LG’s high-end G Flex 2 and will be the brains behind many a flagship smartphone this coming year. The Snapdragon 805 already sets a rather high benchmark for performance and features, so let’s examine how Qualcomm intends to improve its popular 800 series of mobile processors as it moves into the 64-bit generation.

Processing Power

 Snapdragon 810Snapdragon 805Snapdragon 801

MemoryLPDDR4 1600MHz 64-bitLPDDR3 800MHz 64-bitLPDDR3 933MHz 32-bit
DSPHexagon V56Hexagon V50Hexagon V50

The Snapdragon 810 marks the first 800 series chip to depart from Qualcomm’s customized Krait CPU core design and is also the first Qualcomm mobile SoC to reach 20nm. The reasons for the change in CPU cores is that Qualcomm is making the move over to the latest 64-bit ARMv8 architecture, which requires a new CPU design.

The customized 32-bit Krait 450 quad-core makes way for two sets of 64-bit quad-core chips. Four high-performance ARM Cortex-A57s nestle alongside four low-power ARM Cortex-A53s, arranged in a reference big.LITTLE configuration, similar to Samsung big.LITTLE Exynos line-up. Unlike early Samsung chips, all eight cores in the Snapdragon 810 can be active at once, as the chip makes use of Global Task Scheduling.

The Cortex-A57 offers around a 20 to 50 percent boost over the older Cotex-A15 design that Qualcomm’s Krait CPU cores are based on, depending on the scenario. However, this comes at the expense of 20 percent more power consumption. Fortunately, the Cortex-A53 is a more efficient replacement for the low-power Cortex-A7, which, combined with the smaller 20nm manufacturing process, should help offset the battery sapping A57 cores. By efficiently managing workloads across all eight cores, the octa-core big.LITTLE design should result in a higher level of peak performance when needed but a lower level of background and idle power consumption.

When we compared the Snapdragon 805 to the slightly older 801 we were mostly looking at improvements to Qualcomm’s Adreno GPU technology. This time around, the CPU is the biggest change between generations, as the Adreno GPU is simply swapped out from an Adreno 420 in the Snapdragon 805 to a 430 in the 810. That being said, the Adreno 430 supposedly boosts performance by up to 30 percent compared with the Adreno 420, making it around 80 percent faster than the last generation Adreno 330. With gaming on Android becoming a bigger deal each year, the Snapdragon 810 will make sure that frame rate is not an issue.

Performance is expected to improve across the board between the Snapdragon 810 and 805. The new CPU designed should finally see some general performance gains compared to the tried and tested Krait cores in the 32-bit 800 series and the new high-end Adreno GPU should offer a top of the line experience for video content consumers and gamers.

SoC Features

As well as increasing the raw processing power of its latest Snapdragon, Qualcomm has also implemented improved LPDDR4 memory support and a faster Hexagon V56 DSP chip in the 810. The fast 3200MHz RAM data rate and 25.6GB/s memory bandwidth should see applications open and transition that bit smoother on the 810 and the improved DSP chip will help further offset the CPU load for music and high-quality video processing.

Next gen Snapdragon media supportLooking at the rest of the SoC features, we find that the Snapdragon 810 and 805 are rather similar. Both chipsets support dual image sensors up to 55 Megapixels, and are capable of 4K capture and playback with H.264 (AVC) and H.265 (HEVC) formats.

The Snapdragon 810’s ISP has received a modest improvement, moving up to a 14-bit dual-ISP design with a 1.2GPixels/s throughput, improving performance by around 20 percent compared with the 805. NFC, 802.11n/ac WiFi, GPS, and Bluetooth 4.1 support is also identical between the two. Quick Charge 2.0 technology is also supported, with a current draw of up to 3A.

When it comes to displays, both SoCs are suitable for use with up to 4K on-device and can support 1080p and 4K external displays as well. Qualcomm has also been eager to tout its improved LTE data speeds, with both chipsets supporting CAT6 speeds of up to 300 Mbps. Although the 810 now support up to 3×20 MHz carrier aggregation, up from 2x. The modem supports LTE FDD, LTE TDD, WCDMA (DC-HSPA+, DC-HSUPA), CDMA1x, EV-DO Rev. B, TD-SCDMA and GSM/EDGE networks.

What does it mean for me?

Enough of the tech terms, the really important issue is what Qualcomm’s latest chip brings to the consumer experience.

Performance wise, we should expect a modest step up from the Snapdragon 805 and gamers will definitely want to make use of the newer Adreno 430. General app/CPU performance will look something like the Exynos 5433 Galaxy Note 4, which features an octo-core Cortex-A57 and A53 set-up. Battery life is still an issue these days and a big.LITTLE Qualcomm chip should be able to squeeze out a few more hours of life when performing simple tasks. However, battery life when gaming or running more intensive apps is unlikely to change much, as the 20nm energy efficiency gains will likely be offset by increased performance.

Feature wise, those in areas with a fast 4G/LTE network won’t see much of a data speed boost between the Snapdragon 805 and 810, as they both top out at 300Mbps. Average speeds and connection quality may improve in a few areas, as the Snapdragon 810’s modem can connect to three bands at once, rather than two. Phones powered by either SoCs will suite those looking to playback or record high resolution video and image content, as ISP, DSP, camera, and display features and support are virtually identical between the two.

The final major difference between the 810 and 805 comes from the CPU architecture. The Snapdragon 810 is a 64-bit chip, while the 805 is only 32-bit compatible. At the moment, this doesn’t make any major practical difference because 64-bit applications are not widespread. However, as Android Lollipop continues to roll-out and more 64-bit capable smartphones hit the market, the Snapdragon 810 may benefit from slight performance improvements down the line, at least when running certain applications. That said, this might be worth considering if you want the most future-proof smartphone right now.

The Snapdragon 805 was clearly a feature stepping stone between the 64-bit Snapdragon 810 and the Snapdragon 801 found in many of last year’s flagships. We may have seen some features of the 810 already, but the performance gains and more efficient 20nm manufacturing node are the real talking points anyway. Qualcomm’s latest SoC certainly seems to have the performance and features demanded by today’s smartphones and tablets.

  • Ammar sagheer

    810 seems a good offer to me… Hope M9 gets it… And i think its worth upgrading from 801.

    • OptimISh_Pr1m3

      Yeah, I am still using my m7 also. However, I wonder about the heat issue with the 810. Hopefully everything is sorted out, and the m9 (Hima) doesn’t throttle like the m7 did compared to it’s Samsung counterpart.

      • nebulaoperator


        I do have M7 for 21 months now. So far it works fine. Would you tell me what you mean by “throttle like the m7 did compared to it’s Samsung counterpart.” Thanks

        • rritambhar

          exactly my question! as far i remember my m7 still beats samsung counterpart s4..

          • Moh M Kash

            M7 had a problem with the way the device was built which caused the CPU to overheat, hence it throttles (Thermal throttling is when CPU lowers it’s frequency for various reasons, in this case overheating so it can cool down.) Therefore it performance was impacted because of lower CPU frequency.
            There is a solution for the M7 CPU throttling which involves opening up the device and messing about with it, which is risky and voids your warranty, but eventually getting rid of those annoying (You’d know if you experienced them) throttles.

  • 255BB

    i hope a Nexus 5 (2015) will have 810 inside. I am still using a nexus 4 with a snapdragon s4 pro inside.feel a bit slow now.

    • Sky

      OH an internet troll.

    • WestSiide

      Nexus 5 2015? Don’t hold your breath. My N4 still handles everything I throw at it like a champ. A slightly larger screen would be nice, but other than that, I can’t find any reason to “upgrade”. This is the longest I’ve kept a phone, and will probably use it till it dies. The S4 Pro has aged well.

    • Fifth313ment

      My Note 3 blows away both my friends Note 4s in speed, even on games and FPS. I’m guessing because the screen is 2k vs 1080p but the Note 3’s SD800 I should not slouch. Certainly not worth the upgrade from the Note 3 to 4. Now the Note 3 to 5 will be a nice jump! I agree also with the battery people want! I say make my phone a few mms thicker and give me a phone with a 5000mah battery! Anyone agree?

      • Walter White

        My note 4 scores 50,000 on antutu, what’s your note 3 score? Fucking liar.

    • Moh M Kash

      You are. S4 Pro is too old now. Recommend Rooting, Getting rid of bloatware, flashing a costume ROM and Kernel, overclocking and most of all take care of your phone technical wise (Always perform cache cleans……..Etc). This is the only way for you to survive.

      • tim

        what kind of bloatware are you talking about in a Nexus?

  • McLaren F1P1

    These biatch phone makers need to sell themselves as they are improving every standards to get ahead of pc, but are still sticking with 8, 16 or 32GB internal memory! These phones need to have at least 200GB to 1 TB internal memory by default and not cheap 16GB base models!
    4K video, screen, 4GB RAM, octa cores, 6mm thin, 13MP selfie camera and so on, but still 16GB base model! Congrats manufacturers trying to fool us!
    Hope HTC changes that as they are the better group of manufacturers!

    • Gideon Waxfarb

      Sure, if you don’t mind paying $1,500 for your phones.

      • Sinan Cagrı Kurt

        Manufacturing of any high end phones isn’t more than 250$, and they are selling for 700$ even though there are a lot of other expenditures to consider, these guys are making good money out of flagship least they can give 32 gb Base model to us

        • Gideon Waxfarb

          ‘Manufacturing of any high end phones isn’t more than 250$’

          [citation needed] And don’t forget to include R&D + marketing and distribution costs …

          • Sinan Cagrı Kurt

            You should of continue to read my comment, after that sentence I stated “even though there are a lot of other expenditures to consider”

          • Boris Lazarov

            Sony is actually considering selling its mobile phone business, because it is on net loss, although they make great devices.

          • Sinan Cagrı Kurt

            Your Point?

          • Boris Lazarov

            That even when the manufacturing price is far lower than the retail, there are hidden global costs to a business that can be quite significant.

          • Sinan Cagrı Kurt

            Sony never made money out of their mobile division.And Sonys mobile division have been around for about decade.So I wouldn’t show Sony as example.If you can’t make money out of same business for a a decade, then you should reconsider your business plan, not blame hidden costs etc…

          • Aidan Guy Allen

            Yes, But they make very little profit of Phones. They make most of there money from patents. and yes there are other costs they have to pay other than the manufacturing cost which a lot of profit goes to.

          • Phil

            That’s sad because I love my Z3, it’s great for gaming and completely water proof. I dropped it to the bottom of my 55 gal fresh water tank just to test it out and no problems. Try that with an IPhone lol.

          • Flip Jumpman

            Cut out the Marketing and I’ll do the research myself.

          • pjcamp

            It is around $250 to $350 since OnePlus has admitted they are selling theirs for cost.

            That doesn’t mean anyone is making money. Who knows what it is sold to a cell provider for, or what marketing costs, or T&D for the next version, or any number of other issues. Conventional Wisdom is that no company is consistently profitable except Apple and Samsung.

    • supernova

      noob, phones have SSDs inside not mechanical hard drives.SSDs are shit expensive

    • Prestaeus

      32 GB with SD card slot minimum, 64 GB without sdxc. The markup on phones is ridiculous anyway, we may as well have some storage. A Galaxy S5 retails for $600 or more, but costs less than $300 to manufacture. While there are other costs involved, a worst case scenario sees a close to 100% profit per device. I get that these are premium devices, but come on, seriously? Someone correct me, with all the added costs, from manufacture to sale, how much profit is typical on a high end device?

    • Tisoyboy2

      I agree with the internal memory of 16gb being too small. 32gb should be the minimum. But more important is bringing back expandable memory and loosening back up on the read/write permissions. I can’t even save highlights and notes on my books if they are saved on the memory card. The memory card is one of the main reasons I stick with Samsung phones (not saying they’re the best). But it’s necessary considering all the data caps.

    • Aidan Guy Allen

      Dude, 32 is more than enough, and some phones even have the option of 64 Gigs. its because an application etc. on a phone is usually from 50 – 100 MB an hardly ever more than 1 GB. Where as an application on a Console, PC etc. can be up to 100 GB (and that would be a pretty big application).

      • Asap Bryce

        32 GB is not enough when you’re taking 4K video.

  • yeah right

    Encryption runs faster on 64 bit processors.

    • Its not the 64-bitness

      That’s because ARMv8 introduced both 32-bit & 64-bit crypto extensions… Its not to do with the fact that its 64-bit its the fact that there are dedicated instructions

  • deltatux

    Android runs the bulk of their apps in ART which automatically translates the apps to 64-bit as is. Only the small portion of native applications need to be recompiled to take full advantage of 64-bit. However, 64-bit isn’t and shouldn’t be the selling point here, it’s so for marketing purposes because no smartphone app needs to address more than 4GB of memory. The real story here is the bunch of advancements made by ARMv8 and its architectures: A53 and A57. Refinements and changes made there are the real reasons for performance increase.

    64-bit is really only useful for server applications for the market which ARM is aiming for. Phones don’t need 64-bit.

  • Balraj

    I’ll wait for 3 months before picking up sony xperia with 2k display
    Lollipop has problems, 810 heating issues rumors…

    • renz

      then stay with kitkat…..

  • WarRaven

    Now if they could just get a handle on the thermals.

    I doubt this 810 runs well, it’ll be the pocket heater of the year an a decent soc too.
    Under clocked is how we’ll get it or thermally limited to seconds at a time.
    Twas destined for Nexus6, to be 64 like the Nexus9 which has a larger thermal area an not as much issue, but this was an issue then too.

  • tiger

    Heat…and lots of heat…that is what we will get….

    • rritambhar

      will be good for chilly nights,eh mate??? i am up for one considering the cold of east cost.. brrrr.r.

  • Spell check

    “… over the older Cotex-A15 design that Qualcomm’s Krait CPU cores are based on …” Nope it’s their own design based on the ARMv7 ISA not based on ARM’s Cortex-A15 design … Also note the spelling of Cortex!

  • gils001

    I couldn’t help but laugh when I read “older Cotex a15” spell check can be your worse nightmare.

    • Robert Littler

      The newer Cotex a16’s are soo much more absorbent!

  • Duncan_J

    Are there any credible sources confirming SnapDragon 810 thermal issues or is it still speculation.

    I can’t believe that after a few years on top of the Android chip supply chain that qualcomm would release a defective chip.?

  • I read about CPU and GPU and RAM improved. When is 15,000 man battery coming?

    I can play even FIFA 2020 on my Xperia Z2, but it won’t last me even close to 3 hours continuous play.

    Lemme shout here, GIVE US BIGGER BATTERIES! Period. Enough with the ‘crapdragon’ things.

    Mark today somewhere. Likely in 2020, there’s gonna be Snapdragon 2,573 but powered by 2,000 mAh batteries.

    I know Qualcomm doesn’t do batteries, but I’ll recommend they stop their dragon things and make bigger batteries for me, before they continue dgragoning.

    You give me the best performing phone that won’t last me 6 hours, for me, its useless

  • Mārtiņš Balodis

    Mediatek 6795 will beat crap out of shitty snapdragon 810.

    • eilegz

      nope MTK its just for cheap phones for low performance… dont expect that much

  • WiLL

    A short term solution for Qualcomm could be to release the SD 805 on 20nm with a boost in clock speed. Call it the 806. Gives them a few more months to sort the 810.

  • eilegz

    sigh my old nexus 5 snapdragon 800 feeel so outdated now :(

  • What happened to 808?

  • Do you think we will see an even better chipset by the time the Note 5 is announced?

    • tiger

      Samsung reportedly dumpt S810 due to heating issues and will be using its own Exynos chip in upcoming S6.

  • Looks like a great up-gradation, specially considering 64 bit & Octa-Core capabilities.

    • tiger

      No, but 64-bit is PURE marketing!!!

      • Robert Littler

        No. No it’s not. For Apple it was pure marketing, seen as their devices only shipped with 1GB of RAM, 64 bit would have been a disadvantage.

        Many flagship devices are going to be shipping with 4GB of RAM this year. 64 bit is an absolute neccessity.

        • tiger

          HINT: ARMv8 architecture.

          Apple going to “64-bit” was not for marketing you fool! Apple wanted to use ARMv8 architecture (intro late 2012) vs. using the crappy old ARMv7 (over 25 yrs old) like what Android has been stuck on this past year.

          ARMv8 brings with it tremendous performance advantage without revving the crap out of the processor (see Qualcomm ever increasing GHz!).

          What else? UNLIKE Qualcomm or Samsung, from beginning, Apple chose to use 100% Apple design CUSTOM CPU cores for the A7 and A8 chips. S810 is using generic ARM cores…and so is Exynos 7 (by Samsung).

          Qualcomm won’t come out with custom ARMv8 cores until NEXT YEAR. Same with Samsung. This officially puts them 2-3 years BEHIND Apple. THINK about that before responding.

          Why do you think Qualcomm is having heating issues with S810? Because they rushed it…and that is despite using GENERIC cores from ARM.

          Apple A7 (despite being first gen) in 2013 was flawless from day one. Custom designed.

          Switching to 64-bit was NEVER about RAM. The problem is that you ignorant phandroids had no idea what you guys were talking about!

          • Robert Littler

            Wow, a verbose and misguided response, I am neither a phandroid or a fool you angry fanboy.

            I am well aware of the refinements in instruction sets. What I refered to is apple marketing 64 bit as revolutionary. What you seem to be blissfully unaware of is that switching to 64 bit architecture increases the size of the executable files. Program, stack and address pointers become twice as lagre, increasing memory usage 15 to 25%. Shipping a 64 bit chip with 1GB of ram was insane.

            64 bit was ALLWAYS about RAM. New architecture would be beneficial if it was 64 or 32 bit, but its only a matter of time before you hit a hard RAM limit. Invest in transitioning your OS now or later but at some point Apple would have to transition to 64 bit. It was just smart buisness. If you can laud a big number ofer an ignorant client base, well thats just marketing.

          • tiger

            It is revolutionary! They are using a MODERN instruction set vs. one that is over 25 yrs old! Yes, it brought with it 64-bit compatibility…and don’t forget ARMv8 also allows you to run 32-bit a lot better too! Revolutionary? Of course it is.

            And then you add in CUSTOM designed cores, which allows for DOUBLE instructions per cycle over anything else. (Another FACT: Apple’s old A7 chip introduced in 2013 with iPhone 5s can do more instructions/cycle than even S810 that is coming out later THIS year.)

            No, the idea here is much improved computing and efficiency with just 2 cores for a small space. And if more computing is needed (see iPad Air 2), then 3 CUSTOM cores with CUSTOM layout is done.

            Core counts is stupid…and what does Android main chip manufacturer is doing? Promoting 8 cores is insanely stupid.

            Remind me…what is the speed of A7 and A8 chips from Apple? The ONLY ones running at high speed is……………….you guess it! Android! Qualcomm specifically!

            Remind me…when did Big.Little ever conserve battery? Samsung? Nope. Big.Little arch has been a failure…in performance AND efficiency. FACT. Look it up.

            I much rather have 2 (or 3) cores running slow but with modern architecture (and CUSTOM) cores than any generic Big.Little crap with 8 cores.

            Again, A7 and A8 barely reaches 1.4 Ghz yet provides DOUBLE instructions/cycle as ANY chip from Android now or near future (exception being NVIDIA K1 Denver; but that has been a crap-o-la disaster in Nexus tablet). What frequency does S810 run at? And yet it still has heating issues!!!! Again, S810 can only do 3 instructions / cycle because it is based on generic ARM core design which has not improved this since ARMv7.

            Ignorant base? Have you seen the Android fanboys wetting their beds at 8 cores?! Hell, even Qualcomm not so long ago made fun of Mediatek for going 8 cores…stating the exact same reasons as me…and now, they have done the same stupid thing.

            Marketing dude.

          • Robert Littler

            Oh dear, you really have swallowed Apples marketing hook line and sinker.

            Rather than accepting whag these corporations say at face value, you need to stop, think about why they said it and do some research cross referencing several sources. If a claim is fantastic it generaly conceals a falsehood.

            I will give you Nvidia’s Tegra X1 as a recent example, they claim 1 terraflop of performace from this chip, nearly four times the performance of the previos chip and the dame as the worlds fastest supercomputer 15 years ago. This is as true as it is false, as they have added 16 floating point math to the new chip, therefore compardd to mobile chips it is indeed achiving a terraflop. Compared to the prevous chip it is 512 megaflops as if was using 32 bit math, and to the supercomputer it is only able to perform 256 64 bit MFLOPS, or one quarter of the claimed amount.

            Now the Apple A7 and A8 only double their IPC in very specific circumstances, namely 64 bit floating point math on sequential word aligned data. Somethinv that crops up in synthetic benchmarks and image processing, but not fequently in real world use. Normal the speed increase is on the order of 30 to 50%. Throw a real workload at it Though and it can choke, actually delivering worse IPC than its 32 bit predecessor. 3Dmarks’s physics test was a prime example of this, complex equations performed on nonliniar data, of course Apple would not fall over itself to tell you this.

            As to ArmV7 being 25 years old, you are confusing instruction set with architecture, towhich there has been many revisions ArmV8 is just ArmV7 with new extensions and addressing modes, much like AMD64 is the 64 bit version of X86, it is evoulotionary not revolutionary, an importand step forward and apple was first out the gate, kudos to them for that. FYI, cortex A9 came out in 2011.

            Qualcomm was quite right to mock mediatek, as they used 8 low power cores in a hetrogenous arrangement, meaning performance on any one core was terrible. It is totally different to big.LITTLE arrangement Which is to enable a wider dynamic range of performane and power consumption. I can suggest you do some research on what is known as ‘race to idle’.

            And finally I never made any assumpions on the 810 being good or bad, I want to see a finishec product. What I am certain of is that in last years press releases the 810 was intended for tablets, and the 808 was for phones. Once again, research gives some perspective.

          • tiger

            I will come back later…busy now…but S810 is for phones and tabs…do MORE research dude.

          • tiger

            Ahh, the 3D Mark Physics test…you phandroids focus on THAT one subbenchmark…yet, blows off tons of other benchmarks! LOL.

            Here are two links:



            Here’s something…research on Exynos chips…been using big.Little for a while now…see how good it is before preaching to me about its superiority.

            Again, A7 and A8 run at 1.3-1.4 Ghz with custom cores. No overheating. Great performance and efficiency.

            And yes, you need to do more research…LG bend phone has S810. Many more to come. It is the flagship chip for 2015 for Qualcomm.

          • Robert Littler

            Telling to tell someone like you step back and try and see through marketing smoke and mirrors was never going to go well. I have given you balanced arguments with best and worst case senarios.

            I have never once called an Apple product bad or poorly engineered, and ad no point have I even said I use an Android device. Yet you have repeatedly insulted me and called me foolish phandroid.

            You have no interest in learning the technology, you are just looking for arguments to try and browbeat anyone down who quedtions the holy Apple. Which isn’t working because you don’t actually know what you’re talking about.

            So I bid you a good evening, I won’t waste any more time on a one sided debate.

          • tiger

            Marketing? Where have i posted marketing stuff? These are RAW DATA points. Stop with your pathetic crap dude.

            Learning tech? Research? You’re the one that said that S810 is for tablets only! LOL. Then you talk about Big.little running low Ghz, when Apple is already running low Ghz with CUSTOM cores getting double instructions / cycle. LOL.

            Preach some more about big.Little!! It is a FAILURE DESIGN that Qualcomm is resorting to to trick foolish ignorant phandroids like yourself into believing that it works! Samsung has failed at it. And Qualcomm so far seems destined for same failure!
