16-Core Threadripper PRO for sWRX8 workstations

The AMD Ryzen Threadripper PRO 5955WX is a 16-core, 32-thread desktop processor built on the 7 nm Chagall PRO (Zen 3) architecture. It operates at a 4.0 GHz base frequency with a maximum turbo of 4.5 GHz and carries a 280 W TDP. The CPU fits the Socket sWRX8 platform and supports eight-channel DDR4 3200 memory with 64 MB of L3 cache.

Suits multi-threaded workloads.

This processor targets professionals running heavily threaded applications such as rendering, simulation or compilation that can use 16 cores and 32 threads across eight memory channels. It lacks any integrated graphics, so a discrete GPU is mandatory. Buyers who need onboard video output or a lower thermal envelope should consider a different product.

280 W TDP drives cooler and power choices

The 280 W thermal design power is the single specification that determines whether this CPU fits a given build. It requires a robust sWRX8 motherboard, a capable cooling solution rated for at least that heat load, and a power supply with sufficient headroom. No cooler is included in the box.

Questions about this item

What does the 4.5 GHz max turbo mean for single-threaded workloads on the Threadripper PRO 5955WX?

The processor can boost one core to 4.5 GHz when thermal and power headroom allow, giving higher single-thread performance than the 4.0 GHz base clock.

How does the eight-channel DDR4 3200 interface affect memory capacity and speed?

Eight channels let you populate up to eight DIMMs for large total capacity while running each at DDR4 3200; the memory controller caps data rate at that speed.

What cooler mounting and clearance does the sWRX8 socket require for this 280 W CPU?

The sWRX8 socket uses a 4094-pin LGA pattern with a standard Threadripper mounting frame; you need a cooler rated for 280 W TDP that fits the rectangular ILM.
