AMD EPYC 9554P 64-core server processor

The AMD EPYC 9554P is a 64-core, 128-thread server processor built for Socket SP5 platforms. It operates at a base frequency of 3.1 GHz and can reach a maximum turbo frequency of 3.75 GHz. The chip includes 256 MB of L3 cache and has a thermal design power of 360 W. It is sold without a cooling device.

DDR5-4800 twelve-channel memory interface

The integrated memory controller supports DDR5 at 4800 MT/s across twelve channels. This configuration defines the maximum memory bandwidth and capacity ceiling available to the processor. Systems requiring higher memory speeds or different memory generations cannot use this CPU. The memory subsystem is fixed by the processor design.

360 W thermal design power and Socket SP5

The 360 W TDP determines the cooling solution and power delivery infrastructure required for stable operation. The processor fits only motherboards equipped with the Socket SP5 interface. Builds constrained by lower power budgets or different socket types cannot accommodate this part.

Questions about this item

Should I pick the 9554P or another EPYC 9004 SKU for a 64-core requirement?

The 9554P is the only 64-core model in the EPYC 9004 series, so it matches the core-count target directly.

What does the 3.75 GHz max turbo frequency deliver in a live server?

It lets up to 64 cores burst to 3.75 GHz for short periods, raising single-thread and lightly threaded throughput before the 360 W power envelope forces clocks back toward the 3.1 GHz base.

How does the PCIe 5.0 interface limit real-world I/O expansion?

The processor exposes 128 lanes of PCIe 5.0, capping aggregate I/O bandwidth at 128 GB/s and defining the maximum number of GPUs, storage controllers or networking cards the platform can support.
