Speaking at the Morgan Stanley Technology, Media, and Telecom Conference, AMD CTO Mark Papermaster shed some light on AMD’s future products, most notably Zen 4, and a few bits about the Zen 3 refresh “Warhol” expected by the end of this year.
We already have a fair bit of info regarding the mobile APU lineups. Cezanne which was launched at CES this year will be followed by Rembrandt which is the mobile equivalent of Warhol. It will be a Zen 3 refresh on an enhanced version of the 7nm node (called 6nm), along with support for PCIe 4, DDR5/LPDDR5 memory, and Navi 2 (RDNA 2) graphics.
7-nanometer was huge for us. It allowed us to double our core density in the same power envelope that we had. It allowed us to bring very impressive performance for at games in our graphics our Radeon road map. And 7-nanometer and 6-nanometer it’s derivative or what we call a long node in the industry. So they’ve just had a lot of staying power. And we’re right on track with those in five. We have called out with Zen 4, we’ll leverage 5-nanometer.Mark Papermaster, AMD CTO
Earlier I thought this was simply an error as it’d be rather bizarre if AMD opted for a different node just for a single mobile lineup (Rembrandt). However, it looks like AMD may go for TSMC’s 6nm EUV process for both Warhol and Rembrandt. This would also make sense if AMD calls it Ryzen 6000 rather than Ryzen 5000 XT. It’s unclear whether Dragon Crest which is the successor to Van Gogh in 2021 will feature the same 6nm node or retain the existing 7nm process.
Zen 3 is incredibly exciting because it’s taking the performance crown not only in multi-threaded where we already had a leadership position with our second-gen EPYC and our Zen 2-based products, but also in single thread. So, it’s a very exciting time and we don’t stop. There’s — Zen 4 is in completion phase and 5 is in concept design. And so it’s really all about staying focused on road map being there for our customers listening to them folding that in. And that’s why we have hundreds of millions of Zen cores in the market today and growing demand for our products.Mark Papermaster, AMD CTO
Talking about the Zen 4 core uarchitecture, Papermaster said that it is in the completion phase while Zen 5 is in the concept design phase. The 5nm Zen 4 based Raphael and Genoa processors are expected to be AMD’s most incredible processors yet, featuring the newer AM5 socket, a Navi 3x GPU chiplet as well as support for PCIe 5 and DDR5 memory:
