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.

    The new architecture is interesting but 64 bit by itself is useless for now on a phone (as long as there is less than 4GB RAM), even more than Android's quad-core CPUs. Reply

    64Bit isn't just for more addressable RAM. Reply

    Other than more ram and support for larger integers in the main pipeline the difference between generation N 32 bit chips and N+1 64 bit chips is almost entirely stuff that could have been added while staying at 32bits. Reply

    Exactly, the "bitness" of a processor doesn't directly imply performance. The N64 had a 64-bit MIPS R4300 nearly two decades ago, but it's thoroughly outclassed by subsequent 32-bit CPUs. Nevertheless, now is as good a time as any for Apple to deploy a 64-bit ARM core. I wonder how long until Apple starts developing its own ARM cores for Macs... Reply

    In my opinion 64bit CPU is short path to Ax in MACs. Interesting is OpenGL ES 3.0 it mean new GPU. Rogue? Reply

    Don't be an idiot.
    The significant feature is NOT the 64-bitness, it is the ARMv8 ISA.

    But what is the real significance of ARMv8 other than the 64-bit architecture? Reply

    More registers and it standardizes much of what was optional or open in previous ARM ISA revisions. Reply

    I think you're going to be repeating that line over and over for the next few weeks, as the commentariats dump their drivel. Reply

    "64Bit isn't just for more addressable RAM."

    What else is it for? I understand that calculations are still done in 32-bits (even x86 processors do that, only Itanium/IA64 class processors have 64bit datapath).
