AMD EPYC 9965

With 192 cores and 384 threads, the EPYC 9965 is built for the most extreme hyperscale virtualization and container-density deployments in AMD's lineup, exceeding even the 128-core EPYC 9745 and EPYC 9755 by a wide margin. Its 2.25GHz base clock is the lowest of any current EPYC SKU, reflecting the tradeoff of cramming 192 cores into one socket at a manageable 500W.

The EPYC 9965 runs on AMD's SP5 platform with 12-channel DDR5 memory support and up to 128 PCIe 5.0 lanes per socket, though at 192 cores, per-core memory bandwidth is the tightest in the EPYC lineup. It supports both single-socket (1P) and dual-socket (2P) deployments, though most 9965 deployments are single-socket given the extreme core count. At 500W, it requires the most robust cooling infrastructure AMD's server platform supports.

Against the 128-core EPYC 9755 in this catalog, the EPYC 9965 adds 64 more cores at the same 500W envelope by using denser Zen 5c cores and lower clocks throughout. Compared to the Threadripper PRO 9995WX in this catalog, the gap widens further: nearly triple the core count with true dual-socket scalability. It stands alone at the top of the EPYC lineup for pure core density, competing with Intel's absolute highest-density Xeon Scalable parts.
