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).

[9] The Apple A12 SoC features an Apple-designed 64-bit ARMv8.3-A six-core CPU, with two high-performance cores called Vortex, running at 2.49 GHz, and four energy-efficient cores called Tempest.

"[11] This neural network hardware has eight cores[7] and can perform up to 5 trillion 8-bit operations per second.

[12] The A12 is manufactured by TSMC[1] using a 7 nm[5] FinFET process, the first to ship in a consumer product,[4][1] containing 6.9 billion transistors.

[14] The ARMv8.3 instruction set it supports brings a significant security improvement in the form of pointer authentication, which mitigates exploitation techniques such as those involving memory corruption, Jump-Oriented-Programming, and Return-Oriented-Programming.
