Benchmarks: new Exynos 5 Dual handily beats Apple’s A6 chip, Intel’s Atom Z2460

by: Bogdan PetrovanOctober 23, 2012

The new Samsung Chromebook (sold out in hours after being put on sale yesterday) is remarkable not only thanks to its low price of $249, but also due to the processor that powers it – an Exynos 5 Dual.

The Exynos 5 Dual (Exynos 5250) is the world’s first mobile processor built on ARM’s new A15 architecture. For the 5250, Samsung paired a dual-core A15 CPU clocked at 1.7GHz with a Mali T604 GPU, which is another premiere. T604 is based on ARMs Midgard architecture, some of its marquee features being the support for unified shaders, OpenGL ES 3.0 and OpenCL 1.1 full profile. In other words, Samsung has combined the best CPU available with the best GPU available, and both are designed by ARM, which provides the advantage of superior integration. For more about Exynos 5 Dual, check out our full overview here.

Now, with all the processing power that Samsung packed into the Exynos 5250, we were dying to see how the new chip performs. Fortunately, Kevin Tofel from GigaOM put the Exynos 5-powered Chromebook through some benchmarks, to see how it fares against the prior model, which runs on an Intel chip. Predictably, the Intel chip performs better, but what’s more important are the scores obtained by the Exynos 5 Dual chip.

Exynos 5 Dual benchmark scores

Tofel ran several benchmark suites on the new ARM Chromebook. Here are the benchmarks and the scores:

  • SunSpider: 668.5ms (lower is better)
  • V8: 3871 (higher is better)
  • Octane: 3465 (higher is better)

Now that we have these scores, let’s compare them to the main competitors of the Exynos 5 Dual chip: the A6 chip in the iPhone 5 and the Atom Z2460 in the Motorola Razr i.

As you can see, Samsung’s latest chip handily beats the previous leaders, with the difference being especially visible in the SunSpider test. For some perspective, consider that the iPhone 5 is the first device to complete SunSpider in less than 1000ms. At 668.5, the new Exynos just smashes that record.

SunSpider, V8, and Octane  are all JavaScript tests, so results may vary when using other benchmark suites. Still, it’s impressive to see what Samsung was able to achieve, and we are looking forward to see what the Exynos 5 Dual can do in next year’s Samsung Galaxy S4 and Galaxy Note 3.

    I’m thinking I’d want an Exynos 5 quad in next year’s Galaxy.

  • Harry

    It may even be a quad by the time the S4 and Note 3 come around!

    Regardless, I’m hyped for whatever may come next, and I continue to think I may skip the LG Nexus. Thanks Androidauthority!

  • edcobb

    why no s4pro chip specs………bias

    • hot_spare

      S4 Pro uses same Krait CPU architecture with a more powerful Adreno320 GPU. GPU plays no role in javascript/browser benchmarks. All S4 versions should have equal (or very similar) results irrespective of GPU.

      • Legendary

        The S4 Pro in the Optimus G has a 1.5 GHz Quad core Krait based CPU.

        The S4 in the HTC One X has a 1.5 GHz Dual core Krait based CPU.

        For single threaded CPU intensive tasks they should perform similarly.

        For multithreaded or GPU intensive tasks, the S4 Pro should kick the living shit out of the S4.

        • Guillermo Perez-Arguello

          Number 1. The Mali T604 smokes the Adreno320
          Number 2. The Exynos 5250 is 1.7Ghz Dual core, and the 5450 is Quad Core.
          The Dual core version is not going on the GS4

    • anonymous

      Still it doesn’t beat this chip! ;)

    • Guillermo Perez-Arguello

      its still not faster than exynos 5 dual

  • Droids

    If this is going to be in the next Galaxy phone my upgrade just became all the sweeter.

  • Tom

    Please use units on your benchmark number… is it miliseconds to complete?, or calcualtions per second?

    • For Sunspider it’s milliseconds to complete, for the other two it’s just a score (bigger is better).

      • James Leach

        Units aren’t necessary…but the (higher is better) and (lower is better) tags are important.

  • Legendary

    How does it compare to the Snapdragon S4 Pro SoCs?

    • rapes it’s living day lights, a6 is more powerful that s4 pro.

      • latuno760

        Jajajaja no its not. Do research noob!

        • shit! sorry i ment to say that the exynos 5 rapes it and the s4 pro is less powerful than exynos 5

    • Guillermo Perez-Arguello

      The Snapdragon can’t keep up with this combination, not at all… Trust me

  • what about a6x? i wanna see this shit rape the new ipad 4 :D

    • “x” is for the gpu, which has more cores to handle hidpi screen res.

  • blowntoaster

    Waiting for next year’s galaxy flagship just get more painful as samsung releases new tech. Can’t wait to see what a quad core version of this will do.

  • mobile

    Good result at cost of power consumption. The chromebook last only 6.5 hour according to Samsung. This means the Exynos 5250’s buttery efficiency is the worst among any smartphone and tablet processors. It seems to me the Arm a15 is target any but mobile market

    • just me

      Gee, its a laptop , not a phone, Its driving a 11.6 inch screen. Who knows what Samsung has in store for the next Galaxy. This, perhaps optimized for battery life, or a completely different chip. I’m sure its going to be good, either way.

      • The majority of the battery drain is screen size and brightness. CPU power, ironically enough, is only a small percentage of it.

        The battery in the Chromebook does have fewer cells too, so that might also be part of it.

    • Guillermo Perez-Arguello

      maybe the resolution also plays a role?? lol…

    • o_______o awesome :D just wish we could see this beast now

    • It would make more sense for a 16-megapixel camera to shoot 4K video… but that’s just me.

    • xoj_21

      amoled on the s4 will be 440pi, 1080p

      • Kookas

        Some serious improvement in AMOLED tech, then. It’s not currently possible to achieve those densities with OLED.

        • Dulshan Kalpage

          Well they got over Pentile with the Note 2, so I guess they could pull off a Super Amoled Plus HD soon.

          Its not like Samsung to use the same tech over and over again like they have for the GNexus, S3, Note, Note 2, etc; so with the next gen S4, should probably come a major refresh.

          • James Leach

            What do you mean? These devices barely have anything in common…including display tech.

          • Dulshan Kalpage

            All of them, excluding the Note 2 sport Super Amoled displays of Pentile matrix arrangement, which is the base of my argument up there. I have no idea what you’re on about.

    • Guillermo Perez-Arguello

      you’re always here!! lol tell me about yourself


  • This is what i’ve been waiting to hear. Since my contract isn’t over until my birthday in march 2013 I been waiting on news for this chip. Only hard thing to decide on is if i should wait for this in a Galaxy S4 or Note 3 OR to push imagination EXYNOS 5250 QUAD :P THINK :)

    • cpu999

      the exynos 5 quad is the 5450

    • Guillermo Perez-Arguello

      Exynos 5 Quad 5450

  • Marc Ianachi

    For all the very Smart People around here. You should kno that my three years old leptop is also faster than my iPhone 5 about 3 times even so it just has 2.4 ghz and a very old chip architecture. It’s absolutely silly to compare the chips which has been modified for Laptops (if you can call google chrome books this way if you think about their limited software) with chips which were designed to be as efficient as possible to run a smartphone. We just can compare the new Exynos chip when it’s announced for Tablets like the new upcoming Samsung tablet that will be probably announced at the google event on Oct. 29th.

    • liam

      So, your laptop processor which is around twice the clock of the A6 and has a power draw probably around 14 times the A6 is three times faster than the A6? That means the A6 is the more efficient chip in ops per watt. Not only that, but since the A6 is SoC that power draw is for the entire SoC vs. your laptop chip which is likely just the cpu and memory controller.

  • nbtech

    I want to see Clover Trail benchmarks

    • MJD

      Intel Atom Z2760 – SunSpider 714.9 ms Anandtech

  • sam

    The benchmarks are a bit meaningless when they are performed on chrome o.s compared to android/ios for the phones. Hope we see this chip in an android phone soon for benchmarks.

  • Guillermo Perez-Arguello

    WE NEED THE 5250 to be OCd to 2.0Ghz for the GS4, or provide us with the 5450 Quad CPU/T658GPU combo!!!!!

  • Guillermo Perez-Arguello

    Guys, read this too!

    It shows all the other awesome benefits of 5250!! USB 3!!

    • KyleRay

      Don’t forget Multi-boot with full Hardware Virtualization (including Para-Virtualization) that in time have it booting Android as Host OS and even Windows 8 or Ubuntu as Guest OS. The A15 is being optimized to run only a minimum of Guest OS Processes. So even with just 2GB of memory with it’s 12.6GB/s Bandwidth, it should do fine. The Xvisor is being installed on Exynos Chromebook and able to boot Ubuntu now. When they get all this optimized, then dick headed Right Wing Religious Fanatic iCrAppleholics and MicroCrApple Monkey Dancers will be crying!!! ;-P ……including Bogdan! haha.. cuz he hates Samsung!!! ^_^

      • James Leach

        I consider myself educated when it comes to architecture features and design…but to me, even this is gobbly-goop.

  • Should really compare this against the “Clover Trail” benchmarks on AT.

  • Bahaa Chouman

    Which is better for gaming performens?

  • Therealestmc

    This is not fair. It would be better to compare them running an actual OS instead of a browser.

  • Walt French

    I don’t get it.

    This Samsung chip intended for a tablet (and the larger battery that’ll come in the package) is 35% faster than Apple’s recent… phone CPU. But the latest Apple tablet CPU is said to be about twice as fast as the A6, or (quite) roughly 50% faster than the Sammy chip.

    But the Samsung chip is “impressive” because it’s more powerful than the older Apple chip.

    And despite the fact that we’re pretty close to the threshold of usability of faster CPUs. Yes, faster is ALWAYS BETTER. But how much better, and how much battery or cost is it worth? PC sales are apparently peaked because even much faster Intel efforts wouldn’t make people’s work days a minute shorter, and companies aren’t willing to spring for the cost.

    Give Samsung credit: they’ve produced chips that are quite fast enough for what we ask of them. Now, we can move on to new applications: new software, new connectivity, new user experiences, some of which might benefit from this faster CPU.

    But really, the CPU story seems just a bit overblown.

    • yea.. you clearly aren’t getting it.
      that twice as fast as thing you are referring to was for A5X vs. A6X…
      so where did you get that 50% faster than Samsung chip?

      i am pretty sure SoC using A15 would be battery efficient comparable to A6/A6X.

      in the end tho, i will stick to Galaxy Nexus and no tablet for now.
      who cares about cpu too much on a phone (be it a6/s4/exynos) so long as it gets the job done – render the goddamn websites and show me maps and directions..

      for tablets i think hardware is there now, just wish to have a little more app selections for nexus tablets before i jump in.

      • Walt French

        Thanks for pointing out the A6X comparison being to the A5X, not vs the A6. That shifts the guess about its Sunspider score to give the 5250 the edge.

        My other concerns, however, about how users will notice, let alone value fractional-second differences in Sunspider scores. Or Linpack: matrix math on cellphones is done using specialized GPU routines, not generalized floating-point. Seems the biggest question is how carefully the app developer tries for device-specific optimization.

      • Tkiel

        The Apple A6X chip IS dual ARM A15 processors, which is the SAME as the Nexus 10 Exynos 5250, which is also dual A15 processors… The iPad4 has virtually the same power as the Nexus 10.

  • exonys dual dint beat see nexus 10 fuk u bitch but exonys quad can

  • If the next Samsung Series 3 Chromebook (i.e. next year’s model) ends up bearing an Exynos 5450 (quad-core) SoC, then it’s a done deal for me… However, that’s provided it also has an HDMI port like this year’s model does.

  • SuperDuper

    i want an i7 3770 in my smartphone. thats superphone
