Processing Power

The Core i7-7800X is a 6-core / 12-thread processor based on the Skylake (server) (2017−2018) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 4 GHz from a base frequency of 3.5 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 8.25 MB (total) of L3 cache, plus 1 MB (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 12,963, placing it in the Budget performance tier as a Legacy generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,114, while multi-core reaches 6,951. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 6,897.
