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
editThe Neural Engine is used 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
editThe Neural Engine also provides high energy efficiency, allowing real-time AI tasks to be performed with minimal battery consumption.[citation needed] Its on-device processing ensures that sensitive tasks such as facial recognition and voice commands are handled locally, enhancing privacy by keeping user data secure.
Developer tools
editThe 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.
