Both the 4S and 5S had a more significant jump in CPU power over their predecessor than the 4, 5 or 6 had over theirs. The 4S went dual core and the 5s went 64 bits. Both had new capabilities that are core capabilities: Siri and TouchID.Having TouchID will allow the 5S to play more in the apple pay domain than the 5. It may not have NFC but the watch will.
