AMD’s new SP6 socket and Genoa-X plan exposed
It is rumored that AMD will release the EPYC 7004 series server processor code-named Genoa in the fourth quarter of this year, using the new Zen 4 architecture core, up to 96 cores. This is also AMD’s first server platform to support PCIe 5.0 and DDR5 memory, using the new SP5 socket.
According to AMD’s roadmap leaked by AdoredTV, in addition to Genoa, the Bergamo of Zen 4c architecture and the EPYC 7005 series codenamed Turin not only support SP5 sockets but also have a new socket called SP6. According to the roadmap, the SP6 socket has limitations for Zen 4 and Zen 4c architecture processors, such as the maximum number of cores is 32 and 64 respectively, the TDP range is between 70W and 225W, and the number of memory, PCIe, and CXL channels is also reduced.
With AMD’s successful application of 3D V-Cache (3D Vertical Cache) technology on the Zen 3 architecture, which greatly increases the processor’s L3 cache, AMD is also determined to continue this practice on the Zen 4 architecture. The roadmap shows that the Zen 4 architecture EPYC processor with 3D V-Cache technology, codenamed Genoa-X, may be released by the end of the third quarter of 2023.
According to AMD, Genoa-X is also supported by sockets such as SP6, and the platform will be optimized for performance per watt. Perhaps the SP socket will achieve a more energy-saving goal through a single-channel system and reduce the configuration of various aspects, plus other aspects of optimization.
