Apple M1 is a series of ARM-based system-on-a-chip (SoC) designed by Apple Inc., launched 2020 to 2022. It is part of the Apple silicon series, as a central processing unit (CPU) and graphics processing unit (GPU) for its Mac desktops and notebooks, and the iPad Pro and iPad Air tablets.[4] The M1 chip initiated Apple's third change to the instruction set architecture used by Macintosh computers, switching from Intel to Apple silicon fourteen years after they were switched from PowerPC to Intel, and twenty-six years after the transition from the original Motorola 68000 series to PowerPC. At the time of its introduction in 2020, Apple said that the M1 had "the world's fastest CPU core in low power silicon" and the world's best CPU performance per watt.[4][5] Its successor, Apple M2, was announced on June 6, 2022, at Worldwide Developers Conference (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, a larger die size, and a large used interconnect. Apple introduced the M1 Ultra in 2022, a desktop workstation chip containing two interconnected M1 Max units. 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.[6]
The initial versions of the M1 chips contain an architectural defect that permits sandboxed applications to exchange data, violating the security model, an issue that has been described as "mostly harmless".[7]
