Technical Analysis
Detailed breakdown of Core i5-7640X specifications and capabilities.
Processing Power
The Core i5-7640X is a 4-core / 4-thread processor based on the Kaby Lake-X (2017) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 4.2 GHz from a base frequency of 4 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 6 MB (total) of L3 cache, plus 256K (per core) of L2 cache and 64K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 7,060, 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 1,419, while multi-core reaches 3,726. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 3,726.
