Technical Analysis
Detailed breakdown of Core i7-11700B specifications and capabilities.
Processing Power
The Core i7-11700B is a 8-core / 16-thread processor based on the Tiger Lake-H (2021) architecture, manufactured on a 10 nm SuperFin process node. It reaches a maximum boost clock of 4.8 GHz from a base frequency of 3.2 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 24 MB (total) of L3 cache, plus 1.25 MB (per core) of L2 cache and 80 kB (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 21,581, 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 2,265, while multi-core reaches 10,050. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 10,287.
