Future M2 processors, as well as M3s, may be built using a 3nm process

Apple’s upcoming M2 processors, as well as M3s, may be built using a 3nm process. Which is a little surprising, as the M2, as well as the M1, is built using a 5nm process.

A new report from DigiTimes claims that Apple has “booked TSMC capacity for its upcoming 3nm M3 and M2 Pro processors.” In his latest edition of the Power On newsletter, Bloomberg’s Mark Gurman says Apple will release several Macs with M2 and M3 chips this fall and into the first half of 2023. 

He expects to see these M2 Macs soon: M2 Mac mini, M2 Pro Mac mini, M2 Pro and M2 Mx 14-inch and 15-inch MacBook Pros. Gurman says that Apple is also already at work on the M2’s successor, the M3, and the company is planning to use that chip as early as next year with updates to the 13-inch MacBook Air code-named J513, a 15-inch MacBook Air known as J515, a new iMac code-named J43,3 and possibly a 12-inch laptop that’s still in early development. The Sellers Research Group (that’s me) also thinks we’ll see an M2 24-inch iMac in time for the holiday season. I expect the iMac code-named J43,3 to be a 27-inch iMac. And I’m personally dubious that we’ll see a 12-inch MacBook.
