The Intel Core Ultra 7 255H demonstrated impressive single-threaded performance in a recently revealed benchmark run, pulling well ahead of the Ryzen AI 9 HX 370 APU.

However, multi-threaded performance leaves a lot to be desired, owing to the lack of hyperthreading.

Single-thread behemoth

According to the Passmark listing, the Core Ultra 7 255H managed an impressive single-thread score of 4631 points - a whopping 32% improvement over the Core Ultra 7 155H "Meteor Lake-H" CPU.

Arrow Lake-H utilizes Lion Cove performance cores, which are clearly showing their merit, aided by TSMC's N3B process.

Interestingly, this result puts the Core Ultra 7 255H roughly 17% ahead of the AMD Ryzen AI 9 HX 370 "Strix Point" CPU, although the story is wildly different in overall performance, where the Arrow Lake-H part lags behind the Strix Point part by almost 20%.

Arrow Lake-H CPUs are also expected to boast iGPUs with up to eight Xe LPG+ cores, which will be slower than those found in Lunar Lake chips that utilize Xe2 cores
