A7 Processor to Be 31% Faster and 64-Bit, iPhone 5S to Support Motion Tracking?

The next-generation A7 processor in the iPhone 5S will be roughly 31 percent faster than the current A6, according to a tweet by Fox News' Clayton Morris. His sources have also mentioned a "separate chip devoted to motion tracking". It's unclear how Apple would use motion tracking abilities, but it could be developing a new control scheme that uses motion gestures like Samsung has built into its Galaxy S series of smartphones.
