Zen 4 to go to the next node

Digitimes, VideoCardz, and RetiredEngineer (twitter) started an intriguing rumor that Ryzen 4000 might end up at 5nm+. Asking around at a reliable place, we have to disappoint some of you as this won't be the case. The Ryzen 4000 series based on Zen 3 core is still at 7nm.

TSMCs 5nm+ is divided between Apple and Qualcomm for this year with some uncertainty over the Hisilicon 5nm Kirin chip. Mobile gets the latest node as mobile-intent SoCs benefit greatly from the smaller geometry, lower power, and higher performance per square millimeter.

AMD has been toying with 7nm on both CPU and GPU and will get to 5nm very soon, but not with Zen 3 in server or desktop variant and not this year.

Zen 3 has been cooked for a while, it was supposed to launch/get announced in late May in Computex 2020, and now it is obviously poised for later. AMD calls 7nm process from TSMC that is planned for Zen 3 processors 7nm+. The Zen 3 desktop part is codenamed Vermeer, and the server Zen 3 is codenamed Milan.

Zen 4 is the next in line, and this one will end up with a smaller node or 5nm. It is unlikely we will see 5nm AMD products as soon as next year, but we don't know more than that.

What happens after Zen 4 is what piques our interest as the Zen generation was designed initially by Jim Keller and executed by Mike Clark after Keller left.
