Processing Power
The Celeron 3965Y is a 2-core / 2-thread processor based on the Kaby Lake (2016−2019) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 1.3 GHz from a base frequency of 1.5 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 2 MB of L3 cache, plus 512 kB of L2 cache and 128 kB of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 1,201, 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 372, while multi-core reaches 708.
