Product identity

The AMD EPYC 7573X is a 32-core server processor built for the Socket SP3 platform. It targets data-centre operators who need high core density and large cache for virtualisation, database or compute workloads. The part ships without a cooler and requires a motherboard qualified for 280 W TDP.

Sustained-load behaviour

With a 280 W thermal design power the chip maintains its 2.8 GHz base frequency across all 32 cores under continuous load. The 768 MB L3 cache reduces memory latency during long-running jobs, while eight DDR4-3200 channels and 128 PCIe 4.0 lanes keep data flowing to storage and accelerators without bottlenecks.

Deciding specification

The 768 MB L3 cache is the single figure that determines fit: workloads that fit inside this cache see markedly lower latency, while those that exceed it will depend on main-memory bandwidth. Buyers whose datasets are larger than 768 MB should verify memory-channel scaling before committing.

Questions about this item

How much heat does the 280 W TDP produce under continuous load?

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

What memory and motherboard must I already have for this Socket SP3 CPU?

You need a Socket SP3 motherboard with eight DDR4 3200 channels populated to reach the rated memory bandwidth.

Will my existing PCIe 3.0 add-in cards work with the 128 PCIe 4.0 lanes?

Yes, the 128 PCIe 4.0 lanes are backward compatible, so PCIe 3.0 cards will operate at their native speed.
