The Apple A12 Bionic is a 64-bit ARM-based system on a chip (SoC) designed by Apple Inc.[7] It first appeared in the iPhone XS, XS Max and XR which were introduced on September 12, 2018.[7][4] It has two high-performance cores which are claimed to be 15% faster and 40% more energy-efficient than the Apple A11 and four high-efficiency cores which are claimed to use 50% less power than the energy-efficient cores in the A11.[7][6]

Design

The A12 features an Apple-designed 64-bit ARMv8.3-A six-core CPU, with two high-performance cores running at 2.49 GHz called Vortex and four energy-efficient cores called Tempest.[3][4] The A12 also integrates an Apple-designed four-core graphics processing unit (GPU) with 50% faster graphics performance than the A11.[3][7] The A12 includes dedicated neural network hardware that Apple calls a "Next-generation Neural Engine."[8] This neural network hardware has eight cores[6] and can perform up to 5 trillion operations per second.[3][4]

The A12 (internally called the T8020) is manufactured by TSMC[1] using a 7 nm[4] FinFET process, the first to ship in a smartphone,[3][1] and it contains 6.9 billion transistors.[1] The die size of the A12 is 83.27 mm2, 5% smaller than the A11.[9] It is manufactured in a package on package (PoP) together with 4 GB of LPDDR4X memory in the iPhone XS[5] and XS Max[9] and 3 GB of LPDDR4X memory in the iPhone XR. 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.[10]
