An alleged roadmap of AMD's next-gen EPYC Server CPUs and Platform has been leaked out by AdoredTV. The roadmap lists upcoming server CPUs Genoa, Bergamo, Genoa-X, and Turin, along with a new platform known as SP6.
AMD's Alleged EPYC Server CPU & Platform Roadmap Spills The Beans on Genoa-X, Turin, and SP6
We cannot confirm the validity of the roadmap slides hence this post is to be treated as a rumor but most of the details were also reported previously by other leakers so it's worth sharing. First up, there's the EPYC Server CPU roadmap for 2021-2023. The roadmap not only lists down EPYC server chips but also the respective platforms they are aimed at. AMD recently launched its final SP3 platform chips, the EPYC 7003X 'Milan-X' which are based on the Zen 3 core architecture with 3D V-Cache.
EPYC Zen 4(C) Expanded With Genoa, Bergamo, and Genoa-X
Moving on, AMD wants to focus on the SP5 platform which is based around the LGA 6096 socket and will feature at least two generations of processor lineups, Genoa and Bergamo. The AMD EPYC Genoa CPUs will feature up to 96 Zen 4 cores in 200-400W SKUs while Bergamo will feature a total of 128 Zen 4 cores in 320-400W SKUs. The SP5 platform is a high-end design that offers both 1P & 2P support, up to 12-Channel DDR5 memory, up to 160 PCIe Gen 5.0 lanes, and 64 Lanes for CXL V1.1+, and up to 12 PCIe Gen 3.0 lanes.
The same roadmap also mentions Genoa-X, something that was also mentioned by Moore's Law is Dead in his video yesterday. The Genoa-X CPUs are expected to hit production by end of Q3 / early Q1 2023 and will launch around mid of 2023. They will feature a similar design methodology as the Milan-X chips with 3D V-Cache as 'Large L3' is a highlighted feature of the lineup. So in total, SP5 will end up with three EPYC families.
What's SP6? A Cost-Optimized Version of SP5 For Edge Servers
At the same time, AMD is expected to introduce a new platform known as SP6 which will be a more TCO-optimized offering for low-end servers. It will be a 1P solution, offering 6-channel memory, 96 PCIe Gen 5.0 lanes, 48 lanes for CXL V1.1+, and 8 PCIe Gen 3.0 lanes. The platform will feature Zen 4 EPYC CPUs but only the entry-level solutions with up to 32 Zen 4 and up to 64 Zen 4C cores. Their TDPs will range between 70-225W. So it looks like the SP6 platform is designed to support the entry level variants of EPYC Genoa, Bergamo, and even Turin CPUs. It will focus on Density & Perf/Watt optimizations for Edge / Telecommunication segment leadership.
Most of these products are expected to hit the market in the second half of 2022 and the first half of 2024. We can expect a formal announcement of the new roadmap by AMD soon and a possible unveil during the Computex 2022 event which is slated in a few week's time.
