AMD EPYC 8004 series has been verified for SATA-IO: Up to 64 Zen 4 cores using SP6 socket
Recently, Twitter user @momomo_us revealed that AMD EPYC 8004 series server processors have passed SATA-IO certification. Codenamed “Siena,” these processors boast up to 64 Zen 4 architecture cores and utilize the SP6 socket, targeting single-socket, low-end servers with a focus on density, performance-per-watt optimization, and catering to edge and telecom domains, aiming for higher energy efficiency.
The known EPYC 9004 series server processors, codenamed Genoa, Genoa-X, and Bergamo, employ the larger SP5 socket with a maximum TDP of 400W. Although AMD has not yet confirmed the SP6 socket, it was exposed last year, bearing a resemblance to the familiar SP3 socket in size (58.5 x 75.4 mm), with a different LGA package and 4844 pins, noticeably smaller and fewer than the SP5 socket in both dimensions (76.0 x 80.0 mm) and pin count (6069).
Zen 4 and Zen 4c architecture processors using the SP6 socket will have some specification constraints, such as maximum core counts of 32 and 64, TDP ranging from 70W to 225W, and reduced memory, PCIe, and CXL channel numbers. The EPYC 8004 series server processors are said to support six-channel memory, 96 PCIe 5.0 lanes, CXL V1.1+ lanes, and eight PCIe 3.0 lanes.
Siena may not be the only product to utilize the SP6 socket. Rumors suggest that the Ryzen Threadripper 7000 series, codenamed Storm Peak, may also feature two different socket models, including the SP5 and SP6 sockets, with the former corresponding to eight-channel memory and the latter to four-channel memory.
