Apple M1

Apple M1 is a series of ARM-based systems-on-a-chip designed by Apple Inc. as a central processing unit and graphics processing unit for its Mac desktops and notebooks, and the iPad Pro and iPad Air tablets. Its successor, Apple M2, was announced on June 6, 2022 at WWDC. The original M1 chip was introduced in November 2020, and was followed by the professional-focused M1 Pro and M1 Max chips in October 2021. The M1 Max is a higher-powered version of the M1 Pro, with more GPU cores and memory bandwidth and a larger die size. Apple introduced the M1 Ultra in 2022, combining two M1 Max chips in one package. These chips differ largely in size and the number of functional units: for example, while the original M1 has about 16 billion transistors, the M1 Ultra has 114 billion. Apple's macOS and iPadOS operating systems both run on the M1. Initial support for the M1 SoC in the Linux kernel was released in version 5.13 on June 27, 2021.
