32-core EPYC server processor

The AMD EPYC 7543 is a 32-core, 64-thread server CPU built for dual-socket platforms. It runs at a 2.8 GHz base clock with a maximum boost of 3.7 GHz and includes 256 MB of L3 cache. The processor fits Socket SP3 and supports PCIe 4.0 with up to 128 lanes for high-bandwidth I/O.

Tray packaging and configurable TDP

This unit ships as a tray processor without a retail cooler or boxed accessories. The default TDP is 225 W and the configurable TDP range spans 225-240 W, allowing integrators to tune power limits for density or thermal constraints. System builders must provide their own SP3-compatible cooling solution.

Eight-channel DDR4 and enterprise workloads

The memory controller operates eight DDR4 channels at up to 3200 MHz, delivering 204.8 GB/s of peak bandwidth per socket. AMD Infinity Guard and Infinity Architecture features target security and workload affinity for virtualisation, databases and analytics. No integrated graphics are present, so a separate management or display adapter is required.

Otázky k tomuto produktu

Will the 256 MB L3 cache on the EPYC 7543 ever need replacement?

The 256 MB L3 cache is built into the silicon and has no moving parts; it does not wear out and never requires replacement.

What limit appears first when the 32-core processor runs at its 225 W TDP continuously?

The 225 W thermal design power is the first hard limit; the cooling solution must dissipate that heat or the CPU will throttle to stay within its thermal envelope.

How much noise and heat does the 225 W TDP tray CPU produce under all-day load?

The processor itself has no fan; total noise and heat depend on the cooler and chassis airflow chosen to handle the 225 W default TDP.
