TSMC Expected to Begin 3nm Chip Production in Late 2022 Ahead of First M3 Macs
TSMC plans to begin commercial production of chips built on its 3nm process in the fourth quarter of 2022, according to industry sources cited by DigiTimes. The full report has yet to be published, so no additional details are available at this time.

Apple is expected to release its first devices with 3nm chips fabricated by TSMC in 2023, including Macs with M3 chips and iPhone 15 models with A17 chips. As usual, the move to a more advanced process will result in improved performance and power efficiency, which will enable faster speeds and longer battery life on future Macs and iPhones.
The Information's Wayne Ma last month reported that some M3 chips will have up to four dies, which he said could allow for up to a 40-core CPU. By comparison, the M1 chip has an 8-core CPU and the M1 Pro and M1 Max chips have 10-core CPUs.
M1 Macs already offer industry-leading performance-per-watt, while the A15 chip in iPhone 13 models is the fastest processor ever in a smartphone, so the move to a 3nm process within a few years should only bolster Apple's lead in this area.
