Technical Analysis
Detailed breakdown of Core i9-9900KF specifications and capabilities.
Processing Power
The Core i9-9900KF is a 8-core / 16-thread processor based on the Coffee Lake-R (2018−2019) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 5 GHz from a base frequency of 3.6 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 16 MB (total) of L3 cache, plus 256K (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 18,029, placing it in the Mid-Range performance tier as a Legacy generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,720, while multi-core reaches 8,150. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 12,812.
