Intel to begin shifting CPU production to TSMC later this year

Intel will begin shifting its production of consumer CPUs to TSMC later this year. So says market intelligence outfit, TrendForce. 

TrendForce's sources say that Intel will first outsource Core i3 CPUs to TSMC in the second half of this year using TSMC's 5nm process, as used by Apple in its latest iPhone and MacBook chips. Next year, Intel will then move its higher performance models to TSMC's upcoming 3nm node.

We've previously discussed the possibility that Intel will begin to outsource CPU production due to its ongoing problems with its new 10nm production node and also with the 7nm node intended to succeed it. But it's the first we've heard of plans for specific processors and detailed time frames.

If the report is true, the immediate question is what chips, exactly, will move to TSMC 5nm later this year? Intel has always said its radical new Alder Lake hybrid CPUs will be built in-house on 10nm tech. That was confirmed on Monday with a demo of Alder Lake running on what Intel characterised as an 'enhanced superfin 10nm process.

With Alder Lake due out later this year, the question is whether Intel is splitting Alder Lake between TSMC and its own fabs or whether the mooted i3 processors will be based on a previous architecture.

We'd bet on the latter, perhaps with something along the lines of a quad-core Cove-based CPU with internals similar to Tiger Lake or Rocket Lake being sent to TSMC. Then in late 2022, Intel could respin Meteor Lake, the successor to Alder Lake, for TSMC 3nm.

Anyway, all of this is very much TBC. But it aligns with everything we know about Intel's current woes and increasing indications that it will have to outsource at least some CPU production to stay competitive with an increasingly on-form AMD.
