Detailed breakdown of Core Ultra 9 285K specifications and capabilities.
Processing Power
The Core Ultra 9 285K is a 24-core / 24-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 5.6 GHz from a base frequency of 3.7 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 36 MB (total) of L3 cache, plus 3 MB (per core) of L2 cache and 192 kB (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 67,482, placing it in the Enthusiast performance tier as a Recent generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 3,200, while multi-core reaches 22,563. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 45,563.
