A12 Bionic, also known as Apple H11P (engineering name) is a 64-bit hexa-core ARM performance mobile SoC introduced by Apple in late 2018 as a successor to the A11. It is codenamed Cyprus.
Overview[edit]
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).
ISP[edit]
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[edit]
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[edit]
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).
