According to a report by DigiTimes (subscription required), chip maker TSMC is on schedule with its 2nm manufacturing process, which could mean that Apple will start using 2nm chips as soon as next year.
TSMC may be able to start trial runs of 2nm later this year, with small production runs following that, and larger production starting later in 2025. The timing seems to indicate that the A19 processor in the 2025 iPhone Pro would be the first 2nm chip. That could be followed by a 2nm M4 chip in the MacBook Pro and iMac, and maybe any other Mac if it did not get an M3 upgrade (the Mac mini, in particular).
DigiTimes also reports that TSMC is already working on the production process after 2nm, which is 1.4nm. Production of 1.4nm chips isn’t expected until 2027. Also, TSMC was granted more funding by the U.S. government through the CHIPS Act, according to Ars Technica on Monday. TSMC will be building three fabrication plants in Arizona.
