Technical Analysis

Detailed breakdown of Core i3-8109U specifications and capabilities.

Processing Power

The Core i3-8109U is a 2-core / 4-thread processor based on the Coffee Lake-U (2018−2019) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 3.6 GHz from a base frequency of 3 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 4 MB (total) of L3 cache, plus 256K (per core) of L2 cache and 64K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 4,184, placing it in the Entry Level performance tier as a Legacy generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 1,100.
