24-core EPYC 7443 for dense server workloads

The AMD EPYC 7443 is a 24-core, 48-thread server processor built on the Milan architecture. It runs at a 2.85 GHz base frequency and can reach 4.0 GHz max turbo. The chip provides 128 MB of L3 cache and fits the Socket SP3 platform with an eight-channel DDR4 3200 memory controller.

Suited for compute-heavy virtualisation

This processor fits operators who need high core density and large cache within a 200 W thermal envelope. It is not intended for builds that require integrated graphics, desktop consumer sockets or single-thread optimisation beyond the stated turbo frequency.

128 MB L3 cache and 128 PCIe 4.0 lanes decide fit

The 128 MB L3 cache and 128 lanes of PCI Express 4.0 determine whether the part matches your memory and I/O topology. Verify the platform supports Socket SP3 and eight-channel DDR4 before selection.

Questions about this item

How much heat does the 200 W TDP of the EPYC 7443 generate under sustained load?

The processor has a 200 W thermal design power, so a server-grade cooler rated for at least 200 W is required to maintain 2.85 GHz base clocks during continuous operation.

Does the 100-000000340 include a cooler, or must I supply my own SP3 mounting hardware?

The box contains the processor only; you must provide a compatible Socket SP3 heatsink and the platform's mounting mechanism.

Will my existing DDR4 3200 RDIMMs populate all eight memory channels of this 7443?

Yes, the integrated controller runs DDR4 3200 across eight channels, so eight matched RDIMMs will fill every channel for maximum bandwidth.
