The Apple M1, unveiled November 10, 2020, was the first Mac chip of the [[Apple silicon]] era — the A-series architecture scaled to a computer, launched in a MacBook Air with no fan that outran Intel MacBook Pros costing three times as much. Its performance-per-watt broke the industry's assumptions overnight, and Rosetta 2 translated x86 apps fast enough that the two-year Intel transition felt instant.

= Variants =

October 2021's M1 Pro and M1 Max brought the pro-chip ladder: more performance cores, ProRes media engines, and memory bandwidth of 200 and 400 GB/s in the redesigned MacBook Pro 14" and 16". March 2022's M1 Ultra fused two Max dies through UltraFusion — a 2.5 TB/s die-to-die interconnect presenting 20 CPU cores and up to a 64-core GPU as one chip — and launched the Mac Studio.

= Legacy =

The M1 ended fifteen years of Intel Macs and set the template every generation since has followed: base, Pro, Max, Ultra. It also crossed back into iPad — the 2021 iPad Pro and 2022 iPad Air ran the same silicon as the Mac — collapsing the hardware line between Apple's two computer platforms.
