Rumors surrounding the launch of the A7 next month is making the whole internet begin to froth at the mouth. Not only are we supposedly going to see a substantial CPU speed boost over the A6's processor, but sources indicate that Apple is finally making the switch to a 64-bit CPU in its line of mobile devices. While it likely won't make much of a difference right off the bat, it does set the stage for faster apps and more memory down the road.
