Another report from 9To5Mac claims that Apple is testing 64 Bit of A7 chip which is the main reason of this hike in performance. This 64 Bit A7 chipset can handle more complex work which can be done on iOS 7.
But its in testing and chances are very rare that this could make to final version this year and it could land in A8 chipset next year.
