Apple M1
system on a chip (SoC) designed by Apple Inc. for the Macintosh computers and iPad Pro tablets
The Apple M1 is a series of ARM-based system-on-a-chip (SoC) designed by Apple Inc., launched in 2020. It is part of the Apple silicon series, as a central processing unit (CPU) and graphics processing unit (GPU), used for its Mac desktops and notebooks and iPad Pro and iPad Air tablets. 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 switched from PowerPC to Intel, and twenty-six years after their transition from the 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. Its successor, Apple M2, was announced on June 6, 2022, at its 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 Pro shipped with 6 performance and 2 efficiency cores in its default binned configuration, with an optional upgrade to 8 performance cores. The M1 Pro is a scaled up variant of the M1 chip, featuring more powerful and numerous CPU and GPU cores. Additionally, by using LPDDR5 memory at a higher frequency, memory bandwidth increased to 200GB/s.
The M1 Max is a higher-powered version of the M1 Pro with a larger die size. It doubled the GPU cores and memory bandwidth to 32 cores and 400GB/s respectively, keeping the same 10 core CPU.
Apple later introduced the M1 Ultra in 2022, a desktop workstation chip containing two M1 Max units physically interconnected via 'UltraFusion'.
“Apple M1” enters the record as system on a chip (SoC) designed by Apple Inc. for the Macintosh computers and iPad Pro tablets. Crown Archives preserves that source wording while asking what Apple, system and chip can confirm, complicate or overturn.
Why this record matters
“Apple M1” is worth following because a concise public description often conceals a longer documentary argument. Here, Apple, system and chip provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q101439988. None of the 2 selected statements returned an explicit reference. The first chronological checks are 2020, 2022 and 2021.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
