Intel Core Ultra 7 255H Crushes Its Predecessor in PassMark Test
Intel’s new Core Ultra 7 255H has appeared in a PassMark benchmark, showing a massive jump in performance compared to the previous Core Ultra 7 155H. Both processors use the same 28W power, but the new chip is much faster, making it a big upgrade for gaming laptops.
The Core Ultra 7 255H scored 28,867 points in PassMark’s total test, while its predecessor, the Core Ultra 7 155H, got 25,037 points. This means the new chip is about 15% faster in multi-threaded tasks. In single-threaded performance, the difference is even bigger—the Core Ultra 7 255H scored 4,631 points, while the Core Ultra7 155H only managed 3,502 points, showing a 32% improvement.
One key change is that Intel removed Hyper-Threading (HT) in this generation, meaning the Core Ultra7 255H has 16 threads instead of 20 threads like the Core Ultra7 155H. However, it makes up for this with better efficiency and faster clock speeds, reaching up to 5.1 GHz.
Despite having fewer threads, the Core Ultra 7 255H still performs much better than the Core Ultra7 155H, thanks to improvements in Intel’s Arrow Lake-H architecture. It has 6 Performance cores (P-Cores), 8 Efficiency cores (E-Cores), and 2 Low Power Efficient cores (LPE-Cores), along with 24MB of cache.
The total power limit (TBP) is still 28W, with a peak power of 115W when needed. This means the Core Ultra7 255H gives much better performance without using more energy, making it a great choice for gaming laptops.
With this big performance boost, the Core Ultra7 255H helps Intel compete with AMD’s Strix Point processors. While PassMark is not the most trusted benchmark, the Core Ultra7 255H’s 32% increase in single-thread performance and 15% boost in multi-thread performance are impressive improvements over the last generation. Gamers and laptop users looking for more power without higher energy costs will likely find the Core Ultra 7 255H a solid upgrade over the Core Ultra7 155H.
