Detailed breakdown of Celeron G1820T specifications and capabilities.

Processing Power

The Celeron G1820T is a 2-core / 2-thread processor based on the Haswell (2013−2015) architecture, manufactured on a 22 nm process node. It reaches a maximum boost clock of 2.4 GHz from a base frequency of 2.4 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 1,599, 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 415, while multi-core reaches 629.
