48-Core EPYC 9454 for Data Centre Workloads

The AMD EPYC 9454 is a 48-core server processor built for high-density compute environments. It targets operators running virtualised infrastructure, large databases or AI training clusters that demand maximum thread count per socket. The SP5 platform provides twelve memory channels and 128 PCIe 5.0 lanes for balanced I/O.

256 MB L3 Cache and 12-Channel DDR5 4800 Headroom

The 256 MB L3 cache feeds 96 threads with low-latency data, keeping utilisation high on memory-bound workloads. Twelve DDR5 4800 channels deliver aggregate bandwidth that sustains large working sets without stalling. The 290 W TDP marks the thermal ceiling; sustained all-core loads will sit at the 2.75 GHz base frequency rather than the 3.8 GHz single-core boost.

Socket SP5 Platform Constraint

This processor only fits motherboards with the SP5 socket and supporting infrastructure for 12-channel DDR5 and 128 lanes of PCIe 5.0. Existing SP3 or consumer platforms cannot accept it. Buyers without a qualified SP5 server board and adequate cooling for 290 W should not purchase this CPU.

Questions about this item

Will the EPYC 9454 run on an SP3 board I already own?

No, this CPU requires the SP5 socket and will not fit SP3 motherboards.

How can I verify the 96 threads are active after installation?

Check the operating system task manager or run lscpu to confirm 48 cores and 96 threads are detected.

Does the box include a heatsink or thermal paste for the 290 W TDP?

The processor ships without a cooling device; a compatible SP5 heatsink and thermal interface material must be purchased separately.
