Technical Analysis
Detailed breakdown of Ryzen Threadripper PRO 9955WX specifications and capabilities.
Processing Power
The Ryzen Threadripper PRO 9955WX is a 16-core / 32-thread processor based on the Shimada Peak (2025) architecture, manufactured on a 4 nm process node. It reaches a maximum boost clock of 5.4 GHz from a base frequency of 4.5 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 64 MB (total) of L3 cache, plus 1 MB (per core) of L2 cache and 64 kB (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 67,561, placing it in the Enthusiast performance tier as a Current Gen generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 3,016, while multi-core reaches 23,596. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 40,000.
