Technical Analysis
Detailed breakdown of Core i5-12400T specifications and capabilities.
Processing Power
The Core i5-12400T is a 6-core / 12-thread processor based on the Alder Lake-S (2022) architecture, manufactured on a Intel 7 nm process node. It reaches a maximum boost clock of 4.2 GHz from a base frequency of 1.8 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 18 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 15,543, placing it in the Mid-Range performance tier as a Aging generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,650, while multi-core reaches 7,800.
