Technical Analysis
Detailed breakdown of Core i5-1145G7 specifications and capabilities.
Processing Power
The Core i5-1145G7 is a 4-core / 8-thread processor based on the Tiger Lake-UP3 (2020−2021) architecture, manufactured on a 10 nm SuperFin process node. It reaches a maximum boost clock of 4.4 GHz from a base frequency of 2.6 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 8 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 9,266, placing it in the Budget performance tier as a Aging generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,653, while multi-core reaches 4,764. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 5,195.
