Technical Analysis
Detailed breakdown of Core i9-9990XE specifications and capabilities.
Processing Power
The Core i9-9990XE is a 14-core / 28-thread processor based on the Skylake (server) (2017−2018) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 5.1 GHz from a base frequency of 4 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 19.25 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 30,162, 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 1,392, while multi-core reaches 16,199.
