AMD EPYC 9965 192-Core Server Processor

The AMD EPYC 9965 is a 5th Generation server processor built for high-density data centre workloads. It delivers 192 cores and 384 threads in a single Socket SP5 package with a 2.25 GHz base clock and 3.7 GHz maximum turbo frequency. A 384 MB L3 cache and 12-channel DDR5 6400 memory controller support memory-intensive applications.

Suited for dense AI inference

This processor targets operators who need maximum core count per socket to reduce rack count and software licensing costs. It supports 128 PCI Express 5.0 lanes for extensive GPU or accelerator connectivity. Buyers requiring lower thermal output or fewer cores for lighter workloads should evaluate alternative SKUs.

500 W thermal design power requires robust cooling

The 500 W TDP dictates that the host platform must provide adequate heat dissipation; no cooling device is included in the box. System integrators must verify that their chassis, power delivery and firmware support this power envelope before deployment. Socket SP5 compatibility and 12-channel memory population are additional integration prerequisites.

Questions about this item

Which version of the AMD EPYC 9965 should I select?

The product is a single model, 100-000000976, with 192 cores, 384 threads, 384 MB L3 cache, a 2.25 GHz base clock, and a 3.7 GHz max turbo frequency.

What does the 2.25 GHz base clock deliver inside a server?

It provides a guaranteed 192-core frequency at the rated 500 W TDP, while the 3.7 GHz max turbo allows higher burst speeds when thermal headroom exists.

How does the PCIe 5.0 interface with 128 lanes affect expansion?

The 128 PCIe 5.0 lanes connect GPUs, storage controllers, and NICs directly to the CPU, giving each device Gen 5 bandwidth without going through a chipset.
