Apple just announced the iPhones 5S featuring the A7 SoC, which is the world's first consumer ARM based SoC with 64-bit support. We're likely talking about an updated version of Apple's Swift microprocessor with ARMv8 support.

Check out our full coverage of Apple's Town Hall event in our live blog.

    Holy hell! Over 1 billion transistors? That's approaching the transistor count and die size of modern Intel desktop quad-core CPUs. Which I imagine would handily beat these 64-bit ARM cores in performance, though not necessarily power consumption. This is going to be an expensive chip to produce, that's for certain. Reply

    That likely includes the entire SoC which is more than the CPU. I bet most of those transistors are part of the new GPU... Can't wait to see what that is. Reply

    The transistor count for 4 core Haswell with GT2 graphics and hyperthreading is somewhere around 1.4 billion transistors and a 177 mm^2 die I believe, looking at the article here on Anandtech regarding it. So it's really not ~too~ far off. Not sure how the graphics component fairs against whatever's in this A7 chip but I bet the CPU horsepower is far, far below even a very low power 4 core Haswell.

    A ULV HD 4000 was about 3 times faster than the iPad 4's GPU in GLBenchmark 2.7... probably around 4-5X faster than the iPhone 5's based on results of comparable chips (Adreno 320).

    I'd imagine the gap is a bit smaller now, since Haswell GT2 doesn't double performance over the HD 4k.

    but even ULV HD4000 had more power budget then a smartphone SOC. With more power budget, they could really ramp the frequencies, but Apple chooses to throw die area at their chips rather than frequency. Reply

    Keep in mind that one of the things people spend transistors on in mobile SoCs is special-function blocks that do tasks that could be done on the other cores, but do it with less power.

    This is actually a technique that Intel has had to rely on heavily in order to be at all competitive with ARM SoC's in the phone and tablet space.

    Higher clocked MP4 rather than MP3 maybe? 2x doesn't seem like it would need anything drastically new. Reply

    x86-64 is fully capable of 64-bit computations, whoever told you otherwise is wrong. Reply

    Huh, that's strange. That comment shouldn't have ended up here. Reply
