Inside Apple’s A5x Chipset: Dual-Core CPU, Quad-Core GPU

With the announcement of the iPad 3, came the announcement of a new processor: the A5x chipset with (presumably) a dual-core CPU and quad-core GPU. The A5x is more powerful to be sure, but should we think of it as a next-generation chip or merely a spec bump?

Apple says that the A5x is twice as powerful as the A5 found in the iPad 2 and four times more powerful than NVIDIA's Tegra 3 chipset. Under what conditions they performed that test, remains to be seen, but shouldn't come as a shock considering Apple's A4 and A5 chipsets have routinely outperformed more powerful hardware from competitors.

AnandTech believes that the A5x is running the same dual-core Cortex A9 CPU as before, but now features a PowerVR SGX543MP4 GPU, instead of the the dual-core PowerVR SGX543MP2.


    How can a dual-core ARM processor possibly be 4 times faster than a quad-core ARM processor? That would mean each core is 8 times faster, which is clearly rubbish. Maybe the graphics performance is that much better but it will need to be to render all those pixels. I imagine any other tests that show good performance are based on the overall efficiency of iOS over Android, rather than on raw processor speed. Still, I'm sure the sheeple will queue up for days to swap their A5 for A5x.

      OMG! 4 IS more than 2. you've caught them in their lies. they obviously weren't counting on you to do the math. top comment genius.

      more cores isn't more speed. it's more things happening at once. Geez.

      Reread - 4x more powerful.
      which I guess is technically correct


    Higher is worse. :D

    this just in... SKY IS BLUE !

    I'm going to guess here and say that they have used intel's tick tock strategy and die shrunk the A5's processor to a smaller feature size with a few tweaks and replaced the graphics to get the performance increases. Just a guess though.

    without actual data this argument is completely irrelevant. anyone could make a graph like that and say that their products are x times better. if you don't provide the data who can argue against it. a graph without variables, you can tell its made by the marketing department. i love apple

    Useless graph is useless, no label on the axis with which they are using to compare them.

    the Graph label is "Graphics Perfromance" so this is clearly highlighting the new GPU in the chipset

    I happen to like apple products, after using for some years, but one thing I have always hated was their sneaky marketing/advertising. Chief among them is when they used to advertise the iphone for 99 dollars....only if you were new to att and opened a new two year contract. BS.
    Frankly, I can't believe that during a keynote speech, more people didn't walk away insulted rather than impressed after seeing that "graph analysis".
