The Apple A12 Bionic is a 64-bit ARM-based system on a chip (SoC) designed by Apple Inc., part of the Apple silicon series,[8] It first appeared in the iPhone XS and XS Max, iPhone XR, iPad Air (3rd generation), iPad Mini (5th generation), iPad (8th generation) and Apple TV 4K (2nd generation).[8][5] Apple states that the two high-performance cores are 15% faster and 40% more energy-efficient than the Apple A11's, and the four high-efficiency cores use 50% less power than the A11's.[8][7] It is the first mass-market system on a chip to be built using the 7 nm process.[9]
