Technical Analysis
Detailed breakdown of Core i3-8100 specifications and capabilities.
Processing Power
The Core i3-8100 is a 4-core / 4-thread processor based on the Coffee Lake (2017−2019) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 3.6 GHz from a base frequency of 3.6 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 6 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 6,073, 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 1,200, while multi-core reaches 3,600.
