Technical Analysis
Detailed breakdown of Core i3-1005G1 specifications and capabilities.
Processing Power
The Core i3-1005G1 is a 2-core / 4-thread processor based on the Ice Lake (Client) (2019) architecture, manufactured on a 10 nm process node. It reaches a maximum boost clock of 3.4 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 4 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 4,827, 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 603, while multi-core reaches 2,605. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 2,319.
