A recent benchmark for Intel’s Core Ultra 7 255H processor has appeared online. From the data, Arrow Lake-H looks poised to significantly enhance single-threaded performance, though the multi-threaded performance appears to be a letdown, mainly because Intel has removed hyperthreading support.
Impressive Single-Thread Performance
The Passmark score reveals that the Core Ultra 7 255H achieved an outstanding single-thread score of 4631 points, marking a remarkable 32% increase compared to the Core Ultra 7 155H “Meteor Lake-H” CPU. The Arrow Lake-H series utilizes Lion Cove performance cores, which are showing their value, supported by TSMC’s N3B fabrication process. Interestingly, this benchmark positions the Core Ultra 7 255H approximately 17% ahead of the AMD Ryzen AI 9 HX 370 “Strix Point” CPU. However, in terms of overall performance, the Arrow Lake-H model falls short, trailing the Strix Point by nearly 20%.
Generational Improvements
When compared to its previous model, the Core Ultra 7 255H exhibits about a 12% advantage in overall performance. While this is a respectable increase from generation to generation, it’s not nearly as striking as the gains seen in single-threaded performance. Additionally, the Arrow Lake-H chips are anticipated to feature integrated GPUs with up to eight Xe LPG+ cores, which will be less powerful than the Xe2 cores found in Lunar Lake processors. It’s important to note that synthetic benchmarks should be viewed cautiously, as actual performance can vary widely based on specific workloads.
