We’ve already heard that Samsung is close to completing the development of a 64-bit Exynos chip, but now we have official confirmation. A director with Samsung’s System LSI division confirmed during a conference call that the chipmaker is ready to manufacture its first 64-bit SoC, reports Korean website IT Today. The executive also said 64-bit chip will allow the use of large amounts of RAM (more than 4GB) in the second half of 2014.

Shortly after the iPhone launch, Samsung’s CEO JK Shin confirmed that the Korean company is going to ship 64-bit SoCs next year, though that shouldn’t have been a surprise for anyone familiar with ARM’s roadmap for 2014. Shin offered a warning back then, saying we shouldn’t expect the new architecture “in the shortest of time”, prompting us to speculate that the Note 3, not the Galaxy S5, would be the first phone to feature a 64-bit processor.

According to IT Today, the sentiment in the industry is that Samsung will use a 64-bit for the first time on the Galaxy S5, but we still have our doubts. If Android 4.4 doesn’t bring 64-bit support, there will be little benefit for Samsung to rush to deliver a 64-bit processor in time for the S5. We’ll find out soon enough.

    “If Android 4.4 doesn’t bring 64-bit support, there will be little benefit for Samsung to rush to deliver a 64-bit processor in time for the S5. We’ll find out soon enough.”

    Not really, they could easily push out Tizen which already support 64 bit. the timing would be perfect for introducing Tizen to the market, while waiting for Android to support 64 bit, if 4.4 doesn’t already support 64 bit.

    • MasterMuffin

      There’s never a good timing for Tizen… :)

    • Mike Reid

      Interesting idea.

      Claiming 64 bit first could give Tizen some notice.

      Samsung is not going to stop using Android.. that is just a baseless rumor. the lack of Google Apps and the Play Store would be the killer first of all..

  • NeedName

    it would be nice if both 64-bit and cores 3 and 4 were taken advantage of. . . but I seriously doubt apps will be there anytime soon.

    Not true, Android is based on Linux, it’s had the ability to work with 64-bit for a long time. It just needed the hardware.

    • zourite

      Everything is technically possible, but a lot of work has to be done to adapt executable code to use the 64bit capabilities.
      This is a system-wide work and includes all native apps.
      I wonder when Google began all this.

  • Groud Frank

    They will be little benefit even if kit kat is released with 64 bit architecture. All Android apps are currently 32 bit and no device is close to maxing the 4GB limited of 32 bit besides the Note 3. You could make the argument that developers will make the switch to 64 bit but we don’t have hardware to make full and efficient use of 64 bit architecture. Even if all apps were 64 bit, I would like to see a smartphone with an SoC hosting 5 or 6GB of RAM that gives you good battery life. Give us something useful, like a 6400 mAh battery that is compact and small enough to fit into the same dimensions of batteries we currently use in smartphones.

      Go to anandtech site it has been proved 64bit gives 15% cpu speed in app in iphone 5s , it will give android the same benefit.

      • martine

        Yeah but is 15% benefit really worth all the hassles ? To google, hardware maker, developer, and user ?

        • Mozaik

          Anything that improve is benefit.

        • Jake

          By lowering the clock by 15%, the CPU will consume about 28% less power. That heavily matters.

          And please note that this is just the beginning. 15% gain in performance by simply rebuilding existing 32-bit apps is HUGE.

      • Groud Frank

        You’re being very vague. iOS 7 is 64 bit and it may see an increase in speed but people don’t live in iOS, they live in apps. Apps which are still 32 bit and which will see no boost in speed from the processor’s 64 bit status. Instead, the boost in speed for 32 bit systems comes from other components in the phone being more optimised to handle 32 bit software. In fact, that 64 bit processor will do more harm and no good at all. According to recent reports, apps on the 5S crashed twice as much as apps on the older 5. There are also BSOD issues. Try taking out half the RAM out of your computer that sports a 64 bit OS and see if there is a 15% increase in performance. Not trying to be sarcastic, just trying to prove that for 64 bit to work EFFECTIVELY things most align themselves properly; namely more RAM, 64 bit processor, and a few other things. Things that aren’t there yet.

        • zourite

          All Apple apps are already re-coded for 64 bit computing and they gave developpers the tools to do it with their own apps. There are some hiccups here and there but nothing serious and it’s improving very fast (BSOD was caused by old versions of the iWork apps, all of witch have been updated last tuesday). You neglect the commanding force Apple has to drive its ecosystem, develop its software and broadcast the upgrades instantly.
          And this RAM story is becoming a bit old my friend…

          • Groud Frank

            How can the RAM story get old? 64 bit architecture is inextricably linked to accommodating more RAM. Having more RAM is the primary and by far most important aspect of havinghaving a 64 bit processor…… You cannot talk about 64 bit processing without RAM. Even if all the apps were 64 bit then it will not lead to any significant improvement, or any, especially with anything less than 4 GB of RAM. Ask any developer this.

          • zourite

            No, simply no.
            You need 64 bit RAM addressing to be able to use more than 4GB RAM, per app ! This is true of course but doesn’t at all imply that any code written for 64bit needs more than 4GB.
            This is the dumb leitmotiv everyone wanting to bash a Apple is repeating.
            RAM addressing limit and computing speed for one given piece of software ARE NOT RELATED.

          • Groud Frank

            Any improvement in speed on iOS7 comes from ARMv8 technology and improvement and not because of its 64 bit status. That is not up for debate. iOS apps will not see a noticeable difference in speed because the A7 has s 64 bit processor. This too is not up for debate. You cannot use a 64 bit processors to its fullfull potential with only 1GB of RAM. Surprise, surprise, this also is not up for debate. We don’t here, bro?

          • Jake

            @ Groud Frank
            Wow, you know nothing about CPUs.
            On AARCH32, you have only 14 registers available.
            Source addresses, destination addresses, loop counters, coefficients, etc typically occupy half of them already, and you have only about 7 registers to live with which is very limiting.
            On AARCH64 on the other hand, 31 registers are available. When the same rule applies, you have 24 registers free to use which is A LOT!
            With so many free registers, the programmer/compiler can unroll performance critical loops to a degree that the ILP(instruction level parallelism) get absolutely maximized without time consuming interlocks and stack swaps.

            And what do we need for the registers to be available on a 64-bit Soc? A 64-bit OS.

            Another example : 8×8 iDCT is very common in modern day computing, especially in media consuming since It’s absolutely necessary for decoding jpgs and video clips.
            AARCH32 features 32 64-bit NEON registers which is not enough for processing 8×8 iDCT in a single pass.
            NEON32 has to compute the data in slices which consumes time and power.
            AARCH64 features 32 128-bit NEON registers which makes it capable of computing 8×8 iDCT in a single pass.
            Load the data, compute, store the data.
            Job done about 80% faster while consuming 30% less power.

            And again, what’s necessary for this kind of heavy improvements? A 64-bit SoC PLUS a 64-bit OS.

            Being capable of addressing more than 4GB of memory is BY FAR the secondary benefit of 64-bit computing.

            I could also tell you how much more powerful AARCH64 can get with its wider registers dealing with fixed point arithmetics, but it would be simply too much for you.

            So I stop here.

    While they will put these in phones and that is arguably dumb, it does not make the entire logic and concept behind making 64 bit quad core ARM CPUs. Think of more powerful tablets and then laptops and games consoles too. They will be epic when enabled by such chips and new software that can take advantage of them.

  • Amine Elouakil

    64-bit is useless for now what matters is Armv8 instruction sets compatibility

  • Have a feeling note 4 will be awesome.

  • deepen03

    Android 4.4. already supports 64bit… I thought this was confirmed from THIS leaked image a while back?

    • Dexter

      This is like a road map for Android, it could be 4.4 but it can also come in later iterations of android

  • Fantastico

    Why Samsung is rushing a 64-bit chip to market is beyond me. It has nothing to run on it. It sounds like Exynosgate mark II — this year saw the rushed release of botched Exynos “octa” core processors whose cores could not be synchronized correctly, resulting in Samsung using Snapdragons in their top devices instead. Next year, they will hurry development of 64-bit chips and then have to fall back on Qualcomm for more Snapdragons.

    64-bit will not materialize until Android 5 running on the Nexus 6 — that is to say, sometime late next year. Android 4.4 is just an iterative update of the 4.x series. Transitioning from 32-bit to 64-bit is a huge undertaking requiring a complete rewrite of the underlying code. Once the system apps have been updated, developers will have to update their own apps in order to benefit from the optimized instruction set. Even then, few users will benefit, since zillions of Android devices are still running on ICS and earlier versions. I suspect the transition to 64-bit in Android will be almost as slow as it was (and is) in Windows, which remains 32-bit friendly to this day, even though the shift to X86-64 began ten years ago.

    • Gary

      It’s very simple, Samsung plays spec game, they don’t want to look inferior on spec to Apple.

      • Jake

        At this rate, we gonna see the joke of the century really soon :

        Galaxy S5, armed with a 64-bit Soc, running 32-bit Android.

  • somebody

    I dont think 64bit aka 4gb+ ram will be necessary until the start of 2015. Android and ios devices are mainly for media consumption, no need for a large horsepower. Arm can learn to save batery instead of increasing power. More power=more energy usage.

    • Jake

      How wrong. In fact, it’s exactly the opposite.
      Just read my answers to Groud Frank and martine above.

  • dick johnson

    why does android copy everything that apple does? first the fingerprint sensor and now this!! this shows that they do not have any self respect.

  • dnice627

    funny how samsung is all of a sudden ready to push out 64 bit chips shortly after the iphone 5s lauch lol….smh. samsung is nothing more than a tech whore company and millions of people follow the crap and they got the nerve to talk about apple. i have yet to see what the quad this and that does to android when the iphone 5 with dual core was pretty much on par with speed vs top android handsets. Well nothing beats hardware and software integration oh and keeping waiting for kit kat 4.4 lol majority of android handsets wont even get it. Most is stuck on 4.2.2 lmao!!!! Like most say just get the nexus. And already pass a little over a month and apple users is already on 7.0.3 update lol talk about fast service
