AMD · EPYC 9004 · 2023 · SP5
The AMD EPYC 9684X is a server processor with 96 cores, released in 2023 at an MSRP of $14,756. It is part of the EPYC 9004 lineup, using the EPYC 9004 platform, and fits the SP5 socket. Internally, it is built on the "Zen 4" architecture. Thanks to AMD Simultaneous Multi-Threading (SMT), each core can handle two instruction streams simultaneously, yielding a total of 192 threads for improved parallelism. The EPYC 9684X has a base clock of 2.55 GHz and can boost up to 3.7 GHz depending on workload and thermal headroom. AMD manufactures the "Zen 4" silicon on a TSMC 5nm process node. This processor supports DDR5 memory across 12 channels, up to 6TB total, with ECC support standard for data integrity in server workloads. It supports both single-socket (1P) and dual-socket (2P) configurations, with 128 lanes of PCIe 5.0 available for storage, networking and accelerators. With a TDP of 400W, the EPYC 9684X runs hot and requires a capable cooling setup. The cache hierarchy consists of 64KB/core of L1, 1MB/core of L2, and 1152MB of L3 cache — a substantial cache pool well suited to memory-bound enterprise and virtualization workloads.
Flagship Genoa-X — adds 3D V-Cache to the Genoa platform, tripling L3 to a massive 1.15GB. Built for technical computing (EDA, CFD, structural analysis) where cache capacity is the dominant performance factor over raw clock speed.
