Intel's upcoming Core Ultra 7 255H mobile processor shows impressive single-threaded performance in a leaked PassMark benchmark, but its multi-core capabilities raise concerns.

The Passmark results (via Notebookcheck) reveal a significant generational leap in single-threaded performance. The Core Ultra 7 255H scored 4631 points, a 32% increase over the Core Ultra 7 155H CPU. This impressive gain can be attributed to the new “Lion Cove” P-cores and TSMC's N3B process technology. Interestingly, the 255H even outperforms the AMD Ryzen AI 9 HX 370 “Strix Point” APU by around 17% in single-threaded performance.

However, the tables turn regarding its multi-core performance, where the 255H falls behind the Strix Point chip by over 20%. This discrepancy highlights the impact of Intel's decision to remove hyperthreading support from its non-K Core Ultra 200 series CPUs. While this move benefits single-threaded performance, it limits the multi-core capabilities of these processors. Despite the disappointing multi-core results, the Core Ultra 7 255H still shows a respectable 12% multi-threaded performance improvement over its predecessor.

It's worth noting that Arrow Lake-H CPUs will feature integrated GPUs with up to eight Xe LPG+ cores. While these iGPUs are expected to be slower than the Xe2-based graphics in Lunar Lake processors, they should still offer decent performance for casual gaming and everyday tasks. These processors should be available this quarter with new laptops from different manufacturers.

KitGuru says: Based on these results, the Arrow Lake-H processors will likely perform better than AMD's latest Ryzen AI 300 series in gaming when paired with a discrete GPU. However, we expect AMD Strix Point processors to be the better option for productivity.
