AMD Siena CPUs For SP6 Platform To Launch Under EPYC 8004 Branding, Up To 64 Zen 4 Cores
AMD will soon be releasing its Siena CPUs for the SP6 platform which will be branded under the EPYC 8004 family.
The AMD EPYC 8004 "Siena" CPUs will exist alongside the more powerful EPYC 9004 family which includes Genoa, Genoa-X, and Bergamo chips. These chips will be targeting entry-level servers & platforms that are optimized with higher TCO in mind. We recently got to see the first coolers for the SP6 socket which share the same design as the SP3 socket. Both sockets are very similar and retain a maximum of 64 cores per socket. Only the bigger SP5 sockets will be able to feature core counts up to 128 (Bergamo Zen 4C).
The AMD SP6 platform and EPYC Siena lineup 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 under the EPYC Siena family.
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 the Zen 5-based Turin CPUs. It will focus on Density & Perf/Watt optimizations for Edge / Telecommunication segment leadership. Documents discovered by @Olrak (via Anandtech Forums), it looks like the SP6 socket is vastly similar to the existing SP3 socket so the packaging layout of the SP6 chips will be similar compared to existing EPYC CPUs too.
They won't use the full 12-die layout as the AMD EPYC Genoa or Bergamo do but rather stick to an 8-die layout as the existing parts. While the socket looks the same, the internal pin layout has been modified to LGA 4844 vs LGA 4096 (on SP3 sockets). Other measurements are the same at 58.5 x 75.4.

It remains to be seen if a version of SP6 comes to the AMD Threadripper lineup. For now, we know that the next-gen Threadripper 7000 "Storm Peak" family will come in HEDT & Workstation flavors with HEDT offering 4-channel memory support and WS offering 8-channel memory support. AMD is likely to use the SP5/TR5 socket for its WS chips which will feature the LGA 6096 socket that is also used for Genoa / Bergamo chips but the HEDT platform may utilize the SP6/TR6 socket. The next-gen Threadripper chips are expected to launch in Q3 2023.
