EPYC 7473X 24-core server processor

The AMD EPYC 7473X is a 24-core, 48-thread server CPU built for the SP3 socket. It runs at a 2.8 GHz base frequency with a 3.7 GHz maximum boost and provides 768 MB of L3 cache. The processor supports eight-channel DDR4-3200 memory and 128 lanes of PCIe 4.0 connectivity.

Operators running qualified DDR4-3200 platforms

This processor suits operators running qualified DDR4-3200 infrastructure with eight memory channels and 128 lanes of PCIe 4.0. It is not for buyers who need integrated graphics, a lower thermal envelope, or a different socket type. The 240 W TDP requires adequate server cooling solutions.

768 MB L3 cache capacity

The 768 MB L3 cache is the defining specification for latency-sensitive workloads. This large cache reduces memory accesses for complex, data-intensive tasks. Verify that your SP3 platform supports the 240 W power envelope and eight-channel memory topology before deployment.

Questions about this item

Will the EPYC 7473X fit in my existing SP3 motherboard without a BIOS update?

The processor uses the SP3 socket and supports DDR4 3200 memory across eight channels, matching the platform used by other EPYC 7003 series CPUs.

How can I confirm the 768 MB L3 cache is active after installation?

Check the reported L3 cache size in the BIOS or operating system; it should show 768 MB for the 24-core 7473X.

Does the box include a heatsink or thermal paste for the 240 W TDP?

The processor is sold without a cooling device; a compatible SP3 heatsink and thermal interface material must be purchased separately.
