"The Apple A8 is a 64-bit system on a chip (SoC) designed by Apple Inc. It first appeared in the iPhone 6, which was introduced on September 9, 2014. Apple states that it is has 25% better CPU performance and 50% graphics performance while drawing only 50% of the power compared to its predecessor, the Apple A7.

The A8 is manufactured on a 20 nm process by TSMC which is a departure from previous processors for Apples mobile devices which was manufactured by Samsung. It has 1 GB of DDR3 RAM included in the package.

Early benchmarking using the Geekbench application suggests that the processor is dual core, and has a frequency of 1.4 GHz. It also supports Apple's claim of it being 25% faster than the A7."

EDIT:

From AnandTech:

CPU: Enhanced Cyclone (i.e. "Cyclone gen 2") @ 1.4GHz, dual core
GPU: PVR GX6650
RAM: 1GB LPDDR3(?), possibly on-chip

(Everything is still a bit speculative, not taken out of thin air but educated guesses based on the limited info available at this point. I guess things will clear up a bit some time after the 19th.)
