Everything you need to know about Apple's all-new 64-bit A7 system-on-a-chip, and the next generation Cyclone processor
At the heart of every iPhone 5s, iPad Air, and Retina iPad mini beats an Apple A7 system-on-a-chip (SOC). It melds Apple's second generation custom processor, called Cyclone — now based on the ARMv8 architecture — with a PowerVR Series 6 (Rogue) graphics processor. The big news is that the Apple A7 is twice as fast at both general purpose and graphics processing as its predecessor, the Apple A6, yet remains roughly the same size. The bigger news is that the Apple A7 is 64-bit, and the first 64-bit processor crafted for a consumer smartphone, and that it supports OpenGL ES 3.0, and comes with a companion chip, the M7 motion coprocessor.
Does that make the iPhone 5s over powered, or the iPad Air underpowered? Neither — they're both over powered.
