Processing Power

The Core i3-4120U is a 2-core / 4-thread processor based on the Haswell (2013−2015) architecture, manufactured on a 22 nm process node. It reaches a maximum boost clock of 2 GHz from a base frequency of 2 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 3 MB of L3 cache, plus 512 kB of L2 cache and 128 kB of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 1,948, 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 462, while multi-core reaches 1,071.
