Technical Analysis

Detailed breakdown of Core i3-1305U specifications and capabilities.

Processing Power

The Core i3-1305U is a 5-core / 6-thread processor based on the Raptor Lake-U (2023) architecture, manufactured on a Intel 7 nm process node. It reaches a maximum boost clock of 4.5 GHz from a base frequency of 1.6 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 10 MB (total) of L3 cache, plus 1.25 MB (per core) of L2 cache and 80K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 8,634, placing it in the Budget performance tier as a Recent generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,960, while multi-core reaches 1,900. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 4,388.
