Technical Analysis

Detailed breakdown of Core i7-9800X specifications and capabilities.

Processing Power

The Core i7-9800X is a 8-core / 16-thread processor based on the Skylake (server) (2017−2018) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 4.5 GHz from a base frequency of 3.8 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 16.5 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 18,128, 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 1,372, while multi-core reaches 7,552. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 13,067.
