A12X Bionic is a 64-bit octa-core ARM performance mobile system on a chip introduced by Apple in late 2018 as a successor to the A10X.

Overview

Fabricated on TSMC 7 nm process and integrating over 10 billion transistors, the A12X features four big Vortex cores along with four little Tempest high-efficiency cores. Apple claims the big cores are up to 15% faster than the one in the A11 while being up to 40% more efficient. For the four high-efficiency cores, Apple claims up to 50% higher efficiency. All eight cores can operate concurrently.

The A12X features an Apple-designed graphics processor that is said to deliver up to 50% higher performance as well as a neural processor capable of peak performance of 5 TOPS (int8).


Apple A12X

ISP

The A12 incorporates Apple's image signal processor (ISP), codename Petra, for camera related applications. The ISP is said to deliver faster depth engine and an improved video processor.

Integrated Graphics

The A12 incorporates an Apple-designed GPU. The GPU is a seven-core design which is said to deliver 50% performance over the A11 in tessellation and multi-layer rendering as well as lossless memory compression.

Neural Engine

The A12 chip features an improved neural engine, codename Quin. Apple stated this is an 8-core design (the A11 featured what they called a dual-core design). The new engine is capable of performing real-time processing at 5 trillion 8-bit operations per second (up from 600 billion).
