Processing Power
The Xeon W-3365 is a 32-core / 64-thread processor based on the Ice Lake-W (2021) architecture, manufactured on a 10 nm process node. It reaches a maximum boost clock of 4 GHz from a base frequency of 2.7 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 48 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 57,312, placing it in the Enthusiast performance tier as a Aging generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,960, while multi-core reaches 16,817.
