Technical Analysis
Detailed breakdown of Core i7-840QM specifications and capabilities.
Processing Power
The Core i7-840QM is a 4-core / 8-thread processor based on the Clarksfield (2009−2010) architecture, manufactured on a 45 nm process node. It reaches a maximum boost clock of 3.2 GHz from a base frequency of 1.86 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 8 MB (total) of L3 cache, plus 256 kB (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 2,025, placing it in the Entry Level performance tier as a Legacy generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 390, while multi-core reaches 1,050.
