Neural Engine is a series of AI accelerators designed for machine learning by Apple. The first SoC including Neural Engine is Apple A11 Bionic for iPhone 8, 8 Plus and iPhone X introduced in 2017.[1] Since then, all Apple A series SoCs have Neural Engine. In 2020, Apple introduced the Apple M1 for Mac[2] and all Apple M series SoCs have Neural Engine.[3][4][5][6][7]
Apple has stated the Neural Engine in the M4 can perform 38 trillion operations per second (TOPS), an improvement over the 18 TOPS in the M3.[8]
Applications
The Neural Engine is crucial for real-time AI-driven applications such as **Face ID**, **Siri**, and **Augmented Reality (AR)**. It also handles computational photography features, including **Smart HDR** and **Night Mode**, by processing vast amounts of sensor data for real-time image enhancements.[9]
Energy Efficiency and Privacy
The Neural Engine also provides exceptional **energy efficiency**, allowing real-time AI tasks to be performed with minimal battery consumption. Its on-device processing ensures that sensitive tasks like **facial recognition** and **voice commands** are handled locally, enhancing privacy by keeping user data secure.
Developer Tools
The Neural Engine is fully integrated with Apple’s **Core ML** framework, which allows developers to run machine learning models on-device. This integration supports applications like **object recognition**, **natural language processing**, and **gesture detection**, giving developers the tools to harness AI power efficiently.
