What owners and reviewers say
Summarised from 1 source(s), reviewed September 14, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- Reviewers describe it as the fastest mobile CPU they had tested at the time, with a notable multi-threaded lift over the previous generation.
- It brings a desktop-class platform to laptops, with PCIe 5.0 lanes and DDR5-5600 support alongside its high turbo clocks.
Commonly criticised
- It is essentially the prior 13th-gen HX flagship with higher clocks, so it is not worth upgrading to from a 13th-gen machine and needs robust laptop cooling.
