64-core EPYC 9554 for dense compute

The AMD EPYC 9554 is a 64-core, 128-thread server processor built for Socket SP5 platforms. It runs at a 3.1 GHz base frequency and reaches 3.75 GHz maximum turbo. With 256 MB of L3 cache and a 360 W thermal design power, it targets high-density virtualization, database and HPC workloads that need maximum core count in a single socket.

DDR5-4800 twelve-channel memory and PCIe 5.0

The integrated memory controller supports twelve channels of DDR5-4800, providing bandwidth for memory-bound applications. The processor also exposes 128 lanes of PCI Express 5.0 for high-throughput accelerators, storage and networking. No cooling device is included, so a compatible SP5 heat-sink or liquid block must be sourced separately.

360 W TDP dictates platform power and cooling

The 360 W thermal design power is the single figure that determines whether a chassis, power supply and cooling solution can support this CPU. Builders who cannot deliver 360 W of sustained cooling or whose platform power budget is lower should select a lower-TDP EPYC model.

Questions about this item

What cooling is required for the 360 W TDP on the EPYC 9554?

The processor ships without a cooler; you must supply a Socket SP5 heatsink or liquid loop rated for 360 W continuous dissipation.

Which limit appears first when all 64 cores run at 3.1 GHz for hours?

The 360 W thermal ceiling is reached before any frequency throttle, so sustained all-core speed depends entirely on your cooling capacity.

How much power does the 12-channel DDR5 controller draw at full load?

The CPU package is rated at 360 W total; memory subsystem consumption is included in that figure and not itemised separately.
