Technical Analysis
Detailed breakdown of Core i3-2120 specifications and capabilities.
Processing Power
The Core i3-2120 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 3.3 GHz from a base frequency of 3.3 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 1,979, 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 534, while multi-core reaches 1,140. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 1,073.
