Claimed by Apple to be "the first 64-bit chip in the world," the new A7 chip in the iPhone 5S is said to run twice as fast as the A6 chip in the iPhone 5. Apple said the camera app alone will autofocus in half the time it took before, and graphics in games will look exponentially more realistic. Historically, Apple chips have been outsourced to Samsung. Though speculation is swirling that Apple will be returning to Samsung to manufacture future chips, this A7 chip was produced by Taiwanese company TSMC. Apple said iOS 7 was created with the A7 chip in mind.
