New Ryzen 7 H 255 performs almost identically to the 3-year old Ryzen 7 7840HS

Systems shipping with the Ryzen 7 H 255 CPU like the GMK NucBox K12 are now becoming more widely available. After spending some time with a few of these systems, however, buyers may want to consider older and oftentimes cheaper Ryzen 7 7840HS, Ryzen 9 7940HS, or Ryzen 9 7940HS options instead. Performance is also similar to the Ryzen 9 8845HS as previously reported which is arguably far too many processor SKUs with few differentiating factors between them.

Our benchmarks below show that the Ryzen 7 H 255 performs almost exactly the same as the aforementioned alternatives. All four processors share the same number of cores, threads, cache sizes, integrated Radeon 780M graphics, and even lack of an NPU. Indeed, the Ryzen 7 H 255 is really just a rebadged last generation Zen 4 processor despite it launching amongst a sea of faster and more efficient Zen 5 options.

Overall performance is still very good for most HTPC or 4K streaming purposes especially when compared to outdated Iris Xe or Radeon RX Vega mini PCs. Users looking to save a bit of money will nonetheless find that the nearly 3-year old Ryzen 7 7840HS can offer better performance-per-dollar. The AMD CPU naming convention has changed since the days of the Ryzen 7 7840HS and so the Ryzen 7 H 255 isn't making it any easier for buyers who may be unaware of the recent changes.

More benchmarks and comparisons on the Ryzen 7 H 255 can be found on our review of the NucBox K12.
