AMD has just released their 7nm based Zen 2 core architecture but it looks like the development of their post-2020 cores is already underway. While we know about Zen 3 and Zen 4, it looks like their far-future Zen 5 architecture has once again shown up online which more or less confirms it for future generations of Ryzen, Threadripper and EPYC processors.

AMD’s Zen 5 is a post-2020 core architecture that will be featured on future generation processors in the Ryzen, Threadripper and EPYC family. We cannot confirm if AMD will be using the same CPU naming conventions in 2020 and beyond but just like now, all processor families would feature the new architecture.
