iPhone 5S Packs Apple A7 Chip: World's First 64-bit Phone

Apple just revealed the A7 chip that'll be inside each iPhone 5S device, which the company is boasting is the world's first 64-bit smartphone.

Among the claims are a 64-bit desktop-class architecture, modern instruction set, twice the number of general purpose and floating point registers. All of that comes to over 1 billion transistors packed in a 102mm2 die.

Apple also said that iOS 7 is completely reengineered for 64-bit with native kernel, libraries and drivers. All the built-in apps are reengineered, and developers will see a seamless transition.

The A7 chip is making some big performance claims over the A6. Apple says the A7 in the iPhone 5S is twice as fast as the A6 in the iPhone 5 and 5C.

    Doesn't Apple always claim the new chips are 2X faster than the old chips anyway?

    64-bit also makes apps 30% larger...at least that's what we found w/ x86 chips.

    Arm v8 (64-bit) has been around for a while...only at the server level...neat that Apple managed to get this into their custom chip.
