Processing Power

The Celeron N2840 is a 2-core / 2-thread processor based on the Bay Trail-M (2013−2014) architecture, manufactured on a 22 nm process node. It reaches a maximum boost clock of 2.58 GHz from a base frequency of 2.16 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 0 kB of L3 cache, plus 512K (per core) of L2 cache and 56K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 1,331, 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 230, while multi-core reaches 430.
