Processing Power

The Celeron 5305U is a 2-core / 2-thread processor based on the Comet Lake-U (2019−2020) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 2.3 GHz from a base frequency of 2.3 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 2 MB of L3 cache. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 1,307, placing it in the Entry Level performance tier as a Aging generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 480, while multi-core reaches 865.
