Intel Core Ultra 7 255H Shows 32% Faster Performance Than 155H in Early Tests

Intel recently introduced its new Arrow Lake processors for laptops at CES, including high-performance models for gaming and balanced-performance models optimized for battery life. Among them is the Intel Core Ultra 7 255H, which has now undergone early performance tests, showing a significant improvement over its predecessor, the Core Ultra 7 155H.
Significant Performance Gains in Passmark Tests
Performance tests conducted on Passmark reveal that the Core Ultra 7 255H achieved an overall score of 28,867 points, compared to 25,037 points for the 155H. In single-core performance, the 255H scored 4,631 points, while the 155H reached only 3,500 points, marking an over 32% performance increase in single-core tasks. In overall performance, the new processor also shows an improvement of more than 15% over its previous generation counterpart.
Hyperthreading Removed, Yet Performance Remains Strong
These results are even more impressive considering that Hyperthreading is no longer present in the Core Ultra 200-H series. The Core Ultra 7 255H has 16 cores and 16 threads, while the 155H had 16 cores and 22 threads. The removal of Hyperthreading has not negatively impacted performance, suggesting architectural improvements.
More laptops featuring these processors are expected soon, allowing further testing to confirm these initial performance gains.
