Technical Analysis
Detailed breakdown of Core i3-10305 specifications and capabilities.
Processing Power
The Core i3-10305 is a 4-core / 8-thread processor based on the Comet Lake-R (2021) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 4.5 GHz from a base frequency of 3.8 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 8 MB (total) of L3 cache, plus 256 kB (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 9,210, placing it in the Budget performance tier as a Aging generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,536.
