Apple A8

The Apple A8 is a 64-bit ARM based system on a chip (SoC) designed by Apple Inc. It first appeared in the iPhone 6 and iPhone 6 Plus, which were introduced on September 9, 2014. The Apple A8 is sporting a second generation enhanced Cyclone core called Typhoon. The A8 also integrates a graphics processing unit (GPU) which AnandTech believes to be a 4-cluster PowerVR GX6450. On October 16, 2014, Apple introduced a variant of the A8, the A8X, in the iPad Air 2. Compared to the A8, the A8X has improved graphics and CPU performance due to one extra core and higher frequency. The Apple A8 Also includes a second generation motion coprocessor, the M8 Motion coprocessor. Devices that include the Apple A8 include the iPhone 6/6 Plus, iPod Touch 6th Generation, iPad Mini 4th Generation, and the Apple TV 4th Generation.
