Processing Power
The Xeon W-3175X is a 28-core / 56-thread processor based on the Skylake (server) (2017−2018) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 3.8 GHz from a base frequency of 3.1 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 38.5 MB (total) of L3 cache, plus 1 MB (per core) of L2 cache and 64K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 46,125, placing it in the Enthusiast performance tier as a Legacy generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,467, while multi-core reaches 17,358. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 31,350.
