Apples 64bit A7 in the iphone is running at only 1.3GHZ and reaches nearly Snapdragon 800@2.3GHZ results in geekbench 2. So the "fastest ARM CPU phrase is based on the megahertz myth".

So if you clock it (the A7) at 2.3ghz it would be at minimum as fast as the BayTrail.

Check Tegra 6. Or wait for A8. All they need to do is to reduce size and raise clock. But of course they will add also cores and more cache and new functions and .
