Overview

The AMD EPYC 9655P is a server processor with 96 cores, released in 2024 at an MSRP of $10,811. It is part of the EPYC 9005 lineup, using the EPYC 9005 platform, and fits the SP5 socket. Internally, it is built on the "Zen 5" 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 9655P has a base clock of 2.6 GHz and can boost up to 4.5 GHz depending on workload and thermal headroom. AMD manufactures the "Zen 5" silicon on a TSMC 3nm/4nm 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 9655P runs hot and requires a capable cooling setup. The cache hierarchy consists of 80KB/core of L1, 1MB/core of L2, and 384MB of L3 cache — a substantial cache pool well suited to memory-bound enterprise and virtualization workloads.

5th Gen EPYC 'Turin' — full Zen 5 core SKU on the SP5 platform with 12-channel DDR5 and 128 PCIe 5.0 lanes.
