Technical Analysis
Detailed breakdown of Core Ultra 7 155H specifications and capabilities.
Processing Power
The Core Ultra 7 155H is a 16-core / 22-thread processor based on the Meteor Lake-H (2023) architecture, manufactured on a 7 nm process node. It reaches a maximum boost clock of 4.8 GHz from a base frequency of 3.8 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 24 MB (total) of L3 cache, plus 2 MB (per core) of L2 cache and 112 kB (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 24,705, placing it in the Mid-Range performance tier as a Recent generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 2,384, while multi-core reaches 12,433. Cinebench R23 multi-core (measuring sustained rendering workload performance) scores 17,650.
