ARM MacAn ARM-based Mac computer. In late 2020, Apple began switching its Mac hardware from Intel x86 CPUs to Apple's ARM-based M1 CPUs. The first models were the MacBook Air and MacBook Pro. Because iPhones and iPads are ARM based, switching the Mac to ARM chips enables development on one hardware platform across Apple's entire line.
The M1 System-on-Chip (SoC)
Apple's ARM-based SoC is the M1. It contains an 8-core CPU for primary program execution (four performance and four efficiency cores), seven or eight GPU cores for graphics rendering and a 16-core neural engine for AI processing. The ARM Macs contain an emulation layer that runs Intel Mac applications even faster than on Intel CPUs (see Rosetta). See SoC, performance core and x86.
