A Developer's Guide to Apple's 64-Bit A7 Chip

One of the biggest surprises at Apple's iPhone 5S event was the news that the A7 chip inside the phone is 64-bit. Apple touts its new A7 chip as having "desktop-class architecture."

This 64-bit processor — a first we've seen in a smartphone — means apps can now run and be written in 64-bit. In theory, applications can run faster and be more energy-efficient. We've already heard from the gaming community about their take on 64-bit (along with the other graphical improvements to the A7 chip), and the on-stage demo of Infinity Blade III looked stunning.
