AMD releases EPYC “Siena” 8004 series processors

AMD has unveiled its EPYC 8004 server processor series, codenamed “Siena.” Targeting single-socket entry-level servers, these processors are honed for density, and performance-per-watt optimization, catering especially to the edge and telecommunication sectors, striving for heightened energy efficiency and ideal for low Total Cost of Ownership (TCO) power-lean servers.

Fashioned on the Zen 4c architecture, the EPYC 8004 series is integrated with the SP6 socket. The SP6 socket, while mirroring the dimensions of the erstwhile familiar SP3 socket (58.5 x 75.4 mm), boasts a distinctive LGA packaging, featuring 4844 pins—noticeably more compact in both sizes (76.0 x 80.0 mm) and pin count (6096) than the SP5 socket.

The inaugural suite of the EPYC 8004 series avails processors with 8, 16, 24, 32, 48, and 64 cores, encompassing 12 variants, inclusive of models suffixed with “P” and “PN” (with P signifying single-socket and N denoting NEBS/network equipment system-compatible build). L3 cache spans between 16MB to 128MB, base frequencies range from 2.0 GHz to 2.6 GHz, boost frequencies oscillate between 3.0 GHz and 3.1 GHz, and the Thermal Design Power (TDP) lies between 80W and 200W, with select models configurable up to 225W. These processors support 6-channel DDR5-4800 memory, offering a maximum capacity of 1.152TB, in addition to hosting 96 PCIe 5.0 lanes and 48 CXL v1.1+ lanes.

AMD articulated that the Zen 4 series architecture proffers products codenamed Genoa, Genoa-X, Bergamo, and Sienna, adeptly addressing the niche market needs for processors with a substantial core count, spanning data centers, cloud computing, and edge computing domains. In alliance with partners, AMD introduced three systems predicated on the EPYC 8004 series, namely the Dell PowerEdge C6615, Lenovo ThinkEdge Se455, and the SuperMicro WIO system.
