The AMD EPYC 8004 series processor, code-named “Siena,” is an energy efficient line of server processors built on the AMD “Zen 4c” 5nm microarchitecture. The 8004 series features up to 64 cores for single-socket (1P) servers and utilizes up to six channels of DDR5 to deliver high performance bandwidth for demanding applications. The low TDP but high core density makes the 8004 series a small but powerful solution for edge or dense computing environments.
