Threadripper PRO 7975WX workstation CPU

The AMD Ryzen Threadripper PRO 7975WX is a 32-core, 64-thread desktop processor built on the Zen 4 Storm Peak architecture. It runs at a 4.0 GHz base frequency and can boost to 5.3 GHz. The chip delivers 128 MB of L3 cache and 32 MB of L2 cache for high-throughput workloads.

sTR5 socket with eight-channel DDR5-5200

The processor fits the sTR5 platform and requires a TRX50 or WRX90 chipset motherboard. It supports eight memory channels at DDR5-5200 with ECC, freeing bandwidth for large datasets. With 148 total PCIe 5.0 lanes, 128 usable at Gen 5, it leaves ample connectivity for GPUs, storage and networking cards.

Suited for simulation and render farms

Professionals running multi-threaded simulation, 3D rendering or virtualization will benefit from the 350 W TDP and 64 threads. Users who need integrated graphics or a lower-power chip for single-threaded tasks should consider other options.

Questions about this item

What thermal limit does the 350 W TDP impose during sustained all-core workloads?

The 350 W thermal design power is the ceiling the cooling solution must dissipate continuously; if the cooler cannot move that heat the processor will throttle to stay within its thermal envelope.

How loud and hot does the system get when the 32 cores run at 4.0 GHz base clock all day?

Noise and temperature depend entirely on the cooler you install — the CPU ships without one — so a 350 W-rated air tower or liquid loop will run quieter and cooler than an undersized cooler.

Which motherboard socket and chipset must already be in the build for this 7975WX to function?

A motherboard with an sTR5 socket and either the AMD TRX50 or WRX90 chipset is required; no other socket or chipset will accept this processor.
