'''A12 Bionic''' is a {{arch|64}} [[hexa-core]] [[ARM]] performance mobile [[system on a chip]] introduced by [[Apple]] in late [[2018]] as a successor to the {{\\|A11}}.

== Overview ==
[[File:apple a12 chip announcement.png|thumb|150px|right|A12 announcement]]
Fabricated on [[TSMC]] [[7 nm process]] and integrating 6.9 billion [[transistors]], the A12 features two [[big cores|big]] {{apple|Vortex|l=arch}} cores operating at up to 2.4 GHz along with four [[little cores|little]] {{apple|Tempest|l=arch}} 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. Note that all six cores can operate concurrently. 

The A12 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).

== 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 four-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).
