64bit processor introduced in apple gadgets
iOS 7 debuted with the 64-bit Apple A7 processor in the iPhone 5s, iPad Air, and iPad Mini with Retina display. Apple's Xcode 5 IDE allows creation of 64-bit apps from existing code, so the iOS world will see 64-bit apps become common in 2014. As with the transition to 64-bit apps in Mac OS X Snow Leopard, most apps won't really take advantage of the greater processing and memory capabilities in their first 64-bit versions, both because developers won't have figured out how to get the maximum effect in the first go-round, and because they won't want the 32-bit versions of their apps used on older devices to be radically inferior until enough of the market has 64-bit devices.After Apple debuted the A7 in September, several Android smartphone makers said they too would ship 64-bit devices, likely using a recent ARM reference design. But that won't do much for them until Google has a 64-bit version of Android to run on it. Expect that in the second half of 2014, giving iOS nearly a year's lead time in 64-bitness.
