Processing Power
The Core Ultra 7 265K is a 20-core / 20-thread processor based on the Arrow Lake-S (2024−2025) architecture, manufactured on a 3 nm process node. It reaches a maximum boost clock of 5.5 GHz from a base frequency of 3.9 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 30 MB (total) of L3 cache, plus 3 MB (per core) of L2 cache and 112 kB (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 58,789, placing it in the Enthusiast performance tier as a Recent generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 3,283, while multi-core reaches 22,293. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 36,309.
