Just as expected, the newly introduced Apple iPhone 5s looks the same on the outside (if you don't count the new white with gold/champagne color option). It still has the same thin 7.6mm profile and it still weighs merely 112g. However it comes with a number of changes under the hood where pretty much all the work has gone into this time around.

The iPhone 5s makes use of a radically re-engineered new chipset, called A7, which is twice as fast in CPU and GPU computations as the one in the iPhone 5.Based on 64-bit architecture for the first time, the new iPhone 5s is said to be up to 40 times faster than the original iPhone with graphics being up to 53x faster. iOS 7 is now a 64-bit OS, but it's backward compatible with all the currently available 32-bit apps.
