What Apple's 64-Bit Architecture Really Means For Your iPhone

A more thorough technical explanation of 64-bit architecture follows below, but in terms of actual, noticeable differences the A7 processor will bring to the iPhone 5S, the list is surprisingly short. It will help speed up the intensive image processing necessitated by those fancy new camera features. It'll enable games with better graphics and larger worlds. And it'll make CPU-intensive operations—like, say, scanning your fingerprint to unlock your phone—happen without any noticeable lag.

That's what's in it for you right now. But 64-bit is part of a longer game Apple, and every other hardware manufacturer, has been playing for some time. Not only does it allow for more RAM in mobile devices (4GB, an amount no one needs today but the inevitable future), it clears a path for Apple to release a MacBook Air, or some sort of laptop-tablet convertible, on a super-efficient mobile processor. Conversely, it clears the path to put OS X on a mobile device. In short: It positions Apple perfectly for the coming convergence of desktop and mobile.
