Core Ultra 7 255HX review: a more energy-efficient HX processor

Strong single-core performance and solid mid-to-high-end multi-core performance, roughly comparable to the i9-14900HX; its improved efficiency reduces heat and noise at moderate power levels.

A logical but unexciting update: gaming is similar to the i7-14700HX, single-core is faster, and removing Hyper-Threading slightly hurts some extreme multithreaded workloads.
