|Model Number||A12 Bionic|
|Introduction||September 12, 2018 (announced)|
September 21, 2018 (launched)
|Core Name||Vortex, Tempest|
9.89 mm × 8.42 mm
|Word Size||64 bit|
|Max CPUs||1 (Uniprocessor)|
Fabricated on TSMC 7 nm process and integrating 6.9 billion transistors, the A12 features two big Vortex cores operating at up to 2.4 GHz 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. 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).
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.
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.
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).
