Processing Power

The Pentium U5400 is a 2-core / 2-thread processor based on the Arrandale (2010−2011) architecture, manufactured on a 32 nm process node. It reaches a maximum boost clock of 1.2 GHz from a base frequency of 1.2 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 3 MB (total) of L3 cache, plus 256K (per core) of L2 cache and 64K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 1,286, 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 170, while multi-core reaches 300.
