AMD Ryzen Threadripper PRO 9955WX 16-Core 32-Thread sTR5 Processor

The AMD Ryzen Threadripper PRO 9955WX is a high-core-count workstation processor built on AMD's sTR5 platform, designed for professionals who demand sustained multi-threaded performance across compute-intensive workloads. With 16 physical cores and 32 threads, the 9955WX delivers the parallel processing capacity needed for tasks such as 3D rendering, video production, scientific simulation, and large-scale software compilation. The processor operates at a base clock speed of 4.5 GHz, with a maximum turbo frequency reaching 5.4 GHz, allowing it to accelerate single-threaded tasks when workload conditions permit. This combination of a strong base clock and a high boost ceiling means the chip remains responsive during mixed workloads that alternate between threaded and sequential processing. The 9955WX uses the sTR5 socket, which is compatible with AMD's Threadripper PRO platform motherboards. The sTR5 platform is engineered to support the elevated memory bandwidth, PCIe lane counts, and ECC memory capabilities that professional workstation environments require. Users building or upgrading a Threadripper PRO workstation should verify motherboard compatibility with sTR5 before purchasing. The SKU 100-100000725WOF indicates a tray (WOF — Without Fan) packaging, meaning a compatible cooling solution must be sourced separately. Threadripper PRO processors require purpose-built workstation coolers rated for the TDP of this class of chip; standard consumer-grade coolers are not suitable.
