    As part of its report on Apple's custom ARM chip design for the A6 found in the iPhone 5, AnandTech speculated that the improved graphics performance in the iPhone 5 was achieved through the use of a triple-core PowerVR SGX 543MP3 graphics processing unit (GPU) rather than doubling the clock speed of the dual-core SGX 543MP2 found in the A5 or using the quad-core SGX 543MP4 found in the A5X for the third-generation iPad.
    AnandTech has now followed up with a new report based on fresh images from UBM TechInsights showing the layout of the A6 with three graphics cores as had been predicted.

    More information and analysis on the A6 will undoubtedly be forthcoming as UBM TechInsights continues its work, but the first glimpse inside Apple's custom chip design for the iPhone 5 demonstrates how the company has been able to balance processing power needs with die size constraints to achieve significant performance gains for the iPhone 5 compared to its predecessors.

    So if my graphics performance stutters once, the terrorists win?

    ----------

    Quadcore GPU?

    And yet somehow has worse performance.

    Are there any Mac rumors at 'MacRumors'?
    Maybe it's time for a name change.

    Yeah, I forgot how Apple had iPhones and iPads back in the PowerPC days, when this site was created. Thanks for your input. :rolleyes:

    Lol this is way over my head

    Will it play crysis?

    I appreciate MacRumors reporting on stuff like this. They do focus mostly on rumors but this kind of stuff is interesting. I mean if you like rumors, you will like reading this stuff.


    iPhone 5 performs MUCH better in some benchmarks #justsayin

    OpenGL

    since we are talking about multiple GPU cores how about a test that is GPU intensive. benchmarks for things like browsers are nice and all but how about something that's a little more aggressive like OpenGL ES.

    Wait, let me take a closer look at that before I decide how badass it is...

    GLBenchmark results show it is around 2.4x as fast as the A5's GPU.

    Here are some other GLBenchmark scores for reference, higher is better.

    GLBenchmark 2.5 Egypt HD offscreen 1080p (C24Z16):

    iPhone 5: 3003
    iPad 3: 2820
    Galaxy S III: 1708
    iPad 2: 1545
    Nexus 7: 1331
    iPhone 4S: 1252
    One X: 1197
    Galaxy Nexus: 603

    GLBenchmark 2.5 Egypt classic offscreen 1080p (C16Z16):

    iPhone 5: 10349
    iPad 3: 9877
    Galaxy S III: 6662
    iPad 2: 5489
    iPhone 4S: 4535
    Nexus 7: 4301
    One X: 4041
    Galaxy Nexus: 1632

    This thing is a beast. :eek:

    This is awesome. I'm super pumped to see what else Apple has in store for us as far as custom chips in upcoming devices.

    Yes, this is awesome...so you get an extra core but it's still SLOWER and uses MORE POWER than the iPhone 5!!!

    Cool, Slower and consumes more Voltage...usually you only get ONE of those together!!!

    Impressive. Most impressive.

    This goes to show you the benefits of designing your own chips and optimize your own software for it far outweigh simply slapping a bunch of off-the-shelf hardware together and calling it a legitimate iPhone competitor.

    Why does it seem like every post about the iPhone 5 has a retaliation about how the Galaxy S3 is superior, and every post about the S3 has people spouting about the iFive? When I saw a poll some time ago on the MacRumours demographic, it seemed like the majority of us were aged 20-40. Why, then, are we acting like the kids that used to - and unbelievably still do - make "Xbox/PS3 IS BETTER" comments? Pick the piece of technology that works in your favour, and go your separate ways people.

    Sigh, I hate when people go off of numbers alone without any inkling of what they're saying. If number of cores really meant anything, then the Atrix 4G would be just as fast as the 4S. It's about drivers to support the cores, their clock speeds, and the speed of the bus. Performance is based on multiple factors and number of cores is only one of them. #justsayin

    When Steve Jobs announced Apple moving to Intel processors he said something to the extent that the operating system (OS X) is what makes a Mac a Mac.

    The iPhone runs OS X so I suppose one could argue we are still discussing Mac.

    Uh, yeah. Four slower cores.

    Would you rather have a computer with 32 cores (all 486 CPUs), or a computer with "just" 2 cores (new Core i7 CPU)?

    Keep in mind the resolutions here. It's mostly the same GPU chip/architecture, but the iPad requires a lot more horse-power. The iPhone doesn't need that. Less cores = less power draw.

    Just wait for the A6X in the new, newer new iPad.

    Yes, but considering the Samsung Galaxy S3 uses an ARM Mali based GPU and the iPhone 5 uses a PowerVR SGX 543 based GPU the number of cores cannot be directly compared -- they are different architectures.

    The Samsung Galaxy S3 (with its 4 core GPU) barely beat the iPhone 4S (with its dual core GPU) in OpenGL ES performance: it will lose to the iPhone 5.
