Technical Analysis
Detailed breakdown of Core i9-12900HX specifications and capabilities.
Processing Power
The Core i9-12900HX is a 16-core / 24-thread processor based on the Alder Lake-HX (2022) architecture, manufactured on a Intel 7 nm process node. It reaches a maximum boost clock of 5 GHz from a base frequency of 2.3 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 30 MB (total) of L3 cache, plus 1.25 MB (per core) of L2 cache and 80K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 33,018, placing it in the High-End performance tier as a Aging generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 2,426, while multi-core reaches 14,620. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 23,150.
