Technical Analysis
Detailed breakdown of Celeron 4205U specifications and capabilities.
Processing Power
The Celeron 4205U is a 2-core / 2-thread processor based on the Whiskey Lake-U (2018−2019) architecture, manufactured on a 14 nm process node. It reaches a maximum boost clock of 1.8 GHz from a base frequency of 1.8 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 2 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 1,350, 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 347, while multi-core reaches 585.
