Processing Power

The Core i3-2120T is a 2-core / 4-thread processor based on the Sandy Bridge (2011−2013) architecture, manufactured on a 32 nm process node. It reaches a maximum boost clock of 2.6 GHz from a base frequency of 2.6 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 3 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 1,570, 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 403.
