Technical Analysis
Detailed breakdown of Core i5-1240U specifications and capabilities.
Processing Power
The Core i5-1240U is a 10-core / 12-thread processor based on the Alder Lake-U (2022) architecture, manufactured on a Intel 7 nm process node. It reaches a maximum boost clock of 4.4 GHz from a base frequency of 1.1 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 12 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 13,387, placing it in the Budget performance tier as a Aging generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,650.
