AMD EPYC 9354 32-core server processor

The AMD EPYC 9354 is a 4th Generation server processor built for Socket SP5 platforms. It delivers 32 cores and 64 threads at a 3.25 GHz base frequency. The 256 MB L3 cache supports demanding data centre workloads such as virtualisation, database analytics and high-performance computing.

Sustained load behaviour at 280 W TDP

With a 280 W thermal design power the processor maintains its 3.25 GHz base clock under continuous multi-threaded load. All 128 PCIe 5.0 lanes and twelve DDR5 4800 memory channels remain active without throttling. A cooling solution rated for at least 280 W is required because no cooler is included in the box.

Platform checks before ordering

Verify that your motherboard uses the Socket SP5 interface and provides a 12-channel DDR5 memory layout. Confirm the BIOS supports the EPYC 9004 series and that your chassis airflow can dissipate 280 W continuously. Ensure the power delivery subsystem supplies sufficient current for the 280 W TDP rating.

Questions about this item

How much heat does the 280 W TDP produce during continuous all-day operation?

The processor has a 280 W thermal design power, so sustained workloads will dissipate that level of heat and require a server-grade cooler rated for at least 280 W.

Which DDR5 memory speed and channel count must the motherboard support for this CPU?

The integrated memory controller runs DDR5 at 4800 MT/s across 12 channels, so the board must provide 12 DDR5 slots wired for 4800 operation.

Will the 128 PCIe 5.0 lanes work with PCIe 3.0 or 4.0 devices I already own?

Yes, the 128 PCI Express 5.0 lanes are backward compatible with PCIe 3.0 and 4.0 peripherals, which will operate at their native speeds.
