Or they simply jump ship to Intel baytrail z3770 and its successors which currently trump the A7 in most benchmarks.
That's the advantage Android has, they can jump ship to whatever hardware platforms offers best in class. (Note : I did not see any battery usage benchmarks on the baytrail yet, anyone ?)
I was about to say speed is not everything when you talking mobile platforms. The competition continues to be behind apple every step along the way. Moto RAZR Max had a decent process and a battery almost 3X of the iPhone but its battery life under processor intensive activities does not last as long as the iPhone. The analysis of why this is the case is the fact that apple controls the SOC and the software. They do not auto-route the SOC, it appears they are hand routing the layout of the chip which is giving them speed and efficiency that the others can not achieve. IT also appears that iOS and the associated hardware does not spend as much time doing the same tasks as it Android counter parts which allows the processor not to run as long thus getting power savings.
With that said you a can safely assume that any Android device using a Baytrail will not beat an iPhone in overall performance. It may be better in one benchmark but loses in others since Manufacturers do not control all the pieces. Apple has shown their trade offers balance the end users overall experience. Good display, fast enough, and lasts just long enough.
