Processing Power
The Xeon Platinum 8280M is a 28-core / 56-thread processor based on the Cascade Lake-SP (2018) architecture, manufactured on a 14 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 38.5 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 37,665, placing it in the High-End performance tier as a Legacy generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,214, while multi-core reaches 11,500. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 35,400.
