AMD EPYC 9684X 96-Core SP5 Processor

The AMD EPYC 9684X is a 96-core server processor built for the SP5 socket. It runs at a 2.55 GHz base frequency and reaches a 3.42 GHz maximum turbo frequency. The chip provides 1152 MB of L3 cache and supports 128 lanes of PCI Express 5.0 connectivity. It is designed for dense, high-throughput server deployments.

Suits multi-threaded workloads.

This processor suits workloads that scale across 192 threads, such as virtualisation, large-scale databases and high-performance computing. Buyers who need higher single-thread clock speeds or lower power draw should look at other options. The 400 W thermal design demands robust cooling infrastructure.

1152 MB L3 cache capacity

The 1152 MB L3 cache is the largest available in the EPYC 9004 series and directly determines capacity for memory-bound applications. This specification decides whether the part fits workloads that require maximum on-die data retention. Cooling device is not included; a compatible solution must be sourced separately.

Questions about this item

Does the 128 PCIe 5.0 lanes support my existing PCIe 3.0 storage and network cards?

Yes, the 128 lanes operate at PCIe 5.0 and are backward compatible with PCIe 3.0 devices, which will run at their native 3.0 speeds.

What cooling solution do I need for the 400 W TDP on an SP5 socket?

You must provide a compatible SP5 cooler rated for at least 400 W; the processor ships without any cooling device.

How do I verify the 96 cores and 192 threads are active after installation?

Check the OS task manager or run `lscpu` to confirm 96 cores, 192 threads, and DDR5-4800 memory speed across 12 channels.
