'''A12X Bionic''' is a {{arch|64}} [[octa-core]] [[ARM]] 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 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 that single-core performance is 35% faster than the {{\\|A10X}}, while increased core counts increase multi-core performance by up to 90%. All eight cores can operate concurrently. 

The A12X features an Apple-designed graphics processor that is said to deliver twice the performance of the {{\\|A10X}}. Apple characterizes this as "XBox One S-class graphics performance". 

Apple's [[neural processor]] makes its first appearance in an A_X-series chip, delivering a peak performance of 5 TOPS (int8), identical to the A12.

single core: 35%, multi-core: 90%

== 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).
