It is the first mass-market system on a chip to be built using the 7 nm process. Updates for the 8th generation iPad and the 3rd generation iPad Pro will still be supported.
Design
The Apple A12 SoC features an Apple-designed 64-bit
ARMv8.3-A six-core CPU, with two high-performance cores called Vortex, running at 2.49 GHz, and four energy-efficient cores called Tempest.
The Vortex cores are a 7-wide decode

The A12 includes
dedicated neural network hardware that Apple calls a "Next-generation Neural Engine."
This neural network hardware has eight cores
and can perform up to 5 trillion 8-bit operations per second.
Unlike the A11's Neural Engine, third-party apps can access the A12's Neural Engine.
