128-Core EPYC 9754 for dense compute

The AMD EPYC 9754 is a 128-core server processor built on the 9004 series architecture. It targets high-density cloud, virtualisation and HPC workloads that scale across many threads. Buyers needing a smaller core count or lower thermal envelope should look elsewhere.

Socket SP5 with 128 PCIe 5.0 lanes

The processor fits the SP5 socket and exposes 128 lanes of PCI Express 5.0 for accelerators, storage and networking. It also runs 12 channels of DDR5 4800 memory. Systems without an SP5 platform or with fewer memory channels cannot use this part.

Processor only — no cooler included

The box contains the CPU alone; a compatible SP5 cooling solution must be sourced separately. No software licences or mounting hardware are bundled. Integrators should plan for a 360 W thermal design power when selecting that cooler.

Questions about this item

What does 128 cores at 2.25 GHz mean for throughput in a live server?

The 128 cores and 256 threads deliver massive parallel throughput at the 2.25 GHz base frequency, with headroom to 3.1 GHz max turbo for burst workloads.

How does the PCIe 5.0 interface with 128 lanes cap real-world I/O?

PCIe 5.0 provides 128 lanes total, setting the bandwidth ceiling for add-in cards, storage controllers, and interconnects in a single-socket build.

What cooler clearance and power budget does the SP5 socket and 360 W TDP require?

The SP5 socket needs a compatible server heatsink rated for 360 W; no cooler is included, so a qualified SP5 thermal solution is mandatory.
