Processing Power
The Xeon Gold 5318Y is a 24-core / 48-thread processor based on the Ice Lake-SP (2021) architecture, manufactured on a 10 nm process node. It reaches a maximum boost clock of 3.4 GHz from a base frequency of 2.1 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 36 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 33,139, placing it in the High-End performance tier as a Aging generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,251, while multi-core reaches 21,846. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 28,500.
