The AMD EPYC 9754S is a server processor with 128 cores, released in 2023 at an MSRP of $11,900. 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 4c" architecture. Thanks to AMD Simultaneous Multi-Threading (SMT), each core can handle two instruction streams simultaneously, yielding a total of 256 threads for improved parallelism. The EPYC 9754S has a base clock of 2.25 GHz and can boost up to 3.1 GHz depending on workload and thermal headroom. AMD manufactures the "Zen 4c" 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 360W, the EPYC 9754S runs hot and requires a capable cooling setup. The cache hierarchy consists of 64KB/core of L1, 1MB/core of L2, and 256MB of L3 cache — a substantial cache pool well suited to memory-bound enterprise and virtualization workloads.
4th Gen EPYC 'Bergamo' — compact Zen 4c cores on the SP5 platform, optimised for cloud-native core density over per-core clock speed.
