What is the xs processor?

xs processor is A12. iPhone XS is equipped with the A12 Bionic chip, which uses a 7nm process and includes a six-core CPU (composed of two performance cores and four energy efficiency cores), a quad-core GPU, and an eight-core neural network engine. A12’s Neural Engine is built for advanced machine learning for photography, augmented reality and more, and can perform five trillion operations per second.

#The operating environment of this tutorial: IOS 15 system, iPhone XS mobile phone.

xs, the full name of iphone xs, is a mobile phone product released by Apple on September 13, 2018 (September 14, China time) at the Steve Jobs Theater in the United States.

iPhone XS comes in 3 colors: silver, space gray and gold; uses iOS 12 operating system; screen size: 5.8 inches; supports 2436x1125 pixel resolution. Support 4K video shooting. The front camera is 7 million pixels; the rear dual camera is 12 million pixels. iPhone XS comes in three capacities: 64GB, 256GB, and 512GB; the iPhone XS Max phone with dual SIM cards is specially launched in China, and eSIM cards are used in other regions.

iPhone The front is 7 million pixels, f/2.2, with a faster sensor.

A12 Bionic (A12 Bionic) is the industry's first 7nm process chip launched by Apple in 2018, integrating 6.9 billion transistors.

A12 Bionic includes a six-core CPU (composed of two performance cores and four energy-efficiency cores), a quad-core GPU, and an eight-core neural network engine.

A12 Bionic uses a 7-nanometer process chip to improve energy efficiency and performance. A12 Bionic adopts a six-core fusion architecture. The speed of two performance cores is increased by up to 15%, the energy saving of four energy-efficiency cores is up to 50%, and the graphics performance of the four-core graphics processor is increased by up to 50%. It is also equipped with Apple The company designs image signal processors (ISPs) and video encoders, etc.

The A11 Bionic is equipped with a dual-core neural network engine, but the A12 Bionic’s neural network engine has eight cores. Next-generation neural engine is built for advanced machine learning for photography, augmented reality and more. It can perform five trillion operations per second, compared to 600 billion operations per second for A11 Bionic. Core ML, running on A12 Bionic's Neural Engine, is up to nine times faster than A11 Bionic, but uses one-tenth the power of A11 Bionic.

A12 Bionic is installed in iPhone XS, iPhone XS Max, iPhone XR, iPad mini (fifth generation), iPad (eighth generation), iPad Air (third generation) and Apple TV 4K (second generation). Generation) [5] on. The 6-core central processor, 4-core graphics processor and 8-core neural network engine included in the A12 Bionic are all independently developed by Apple.
