AMD 2nm Zen 6 “Morpheus” & 3nm Zen 5 “Nirvana” Core Architectures For Future EPYC CPUs Leak Out

wccftech.com:

AMD seems to be working hard to bring forward its next-gen Zen 5 and Zen 6 CPUs that have appeared within an engineer's profile.

Although AMD's Zen 5 CPUs have been confirmed by the chipmaker itself, the leak points out to the future Zen 6 CPUs too along with the codenames for the core architecture that is used internally by AMD. According to the leaked description, the specific task that the engineer was responsible for is the power management project for at least three core IPs starting with the Zen 4 core which began in Q1 2020 followed by Zen 5 in Q1 2021, and then Zen 6 in Q1 2023.

The Zen 4 core architecture which currently powers the AMD Ryzen 7000 and EPYC Genoa lineup had work on power management beginning in Q1 2020 so a launch in Q3 2022 means that it took around 2.5 years for the final chips to come to fruition. In a similar fashion, the first Zen 5 CPUs are most likely to appear in the second half of 2024 while the Zen 6 CPUs will come around 2H 2025 or later.

As for the codenames, we also get to know what Zen 5 and Zen 6 are internally referred to as. The AMD Zen 4 cores based on the 5nm process node are codenamed Persephone. The Zen 5 core that utilizes a 3nm process node will use the Nirvana codename though the Zen 5C cores may utilize a totally different name. Also, Zen 5 comes in both 4nm and 3nm flavors bu the server chips here are tagged as a 3nm part.

Finally, we have the Zen 6 CPUs which are said to utilize a 2nm process node for servers and have been codenamed Morpheus. Those are interesting choices of codenames but do remember that we are still years away from the launch of Zen 5 and Zen 6 core architectures as AMD isn't quite yet done with its Zen 4 architecture.
