Neural Engine

Neural Engine is a series of AI accelerators designed for machine learning by Apple. Neural Engine was first introduced with the A11 Bionic system-on-a-chip (SoC), used in the iPhone 8, iPhone 8 Plus and iPhone X from 2017. In 2020, Apple introduced its M1 processor for its Mac computers which also used a Neural Engine. Every A-series and M-series processor since 2017 has included a Neural Engine.

Apple services such as its Siri virtual assistant, Face ID facial recognition and Apple Intelligence AI services are powered by the Neural Engine, and since this is handled on-device, user data is secure.
