AMD just released the 7nm Ryzen 3000 CPUs based on the Zen 2 microarchitecture which has been giving Intel’s flagship chips quite a bit of trouble. However, it seems that team red isn’t slowing down anytime soon. The Zen 3 design has already been finalized while Zen 4 and Zen 5 are being worked upon. The LinkedIn profile of AMD’s chip architect, David Suggs further corroborates this.
Suggs is one of the key figures at AMD and has been with the company for more than fourteen years now. He was also one of the leads on the recently released Zen 2 architecture, and it seems like his next project is the Zen 5 design slated for release in 2022-2023. Considering that the Zen 2 cores leverage the 7nm node and Zen 3 will be based on 7nm+, it’s very likely that Zen 4 and Zen will use the 5nm process.
Both Samsung as well as TSMC have started commercially producing chips based on the 5nm technology, and are expecting them to be ready by 2020. That’s two years before Zen 5, so we can say with a deal of certainty that Zen 4 will be using the 5nm while Zen 5 will be based on the 5nm+ or maybe even a more advanced process.
Unlike the second-gen Ryzen processors which leverage the Zen+ design, like Zen 2, Zen 3 and Zen 4 will be major improvements over their predecessors as they won’t include solely the migration to a smaller process. Intel, on the other hand, is still stuck on the 14nm node, with the desktop Ice Lake processors still not finalized. The initial 10th Gen chips will most likely be the Comet Lake CPUs based on the 14nm process. Intel expects to migrate to the 7nm process by 2022-23. It’ll be interesting to see how this pans out.
