AMD has been receiving lots of praise for its lineup of Zen 5 processors. On the lower-end of the product spectrum, however, the chipmaker is still releasing new processors utilizing the older Zen 4 architecture. One of these processors is the mobile Ryzen 7 H 255 now widely available on certain systems including the recent Beelink SER9 Pro mini PC.
As shown by our benchmarks below, users can expect the Ryzen 7 H 255 to perform almost identically to the older Ryzen 7 8845HS or Ryzen 9 8945HS all of which are also based on the Zen 4 platform. When compared to a Zen 5 processor like the Ryzen AI 9 HX 370, the Ryzen 7 H 255 is about 25 percent slower in traditional multi-threaded tasks. Indeed, the new CPU shares the exact same core count and cache sizes as the Ryzen 7 8845HS but with a fancier name.
Integrated graphics performance and power consumption are also just marginally better than the Ryzen 7 8845HS at best and so performance-per-watt remains about the same. These signs suggest a simple rebadge and a processor that you should generally avoid since older hardware offer essentially the same performance for less.
More benchmarks and comparisons can be found on our review of the Beelink SER9 Pro.
