Additional PassMark testing reveals the Intel Core Ultra X7 358H has surpassed its direct predecessor in multi-core performance, though margins remain narrow. The Panther Lake processor scored 32,003 points across multiple samples, delivering roughly 4% better multi-threaded results than the Core Ultra 7 255H while trailing by 1.4% in single-core evaluation. Testing confirmed a turbo frequency reaching 4.8 GHz.
The gains appear modest compared to the previous generation leap from 155H to 255H, which delivered approximately 20% improvements in both single and multi-threaded workloads. Engineers attribute the smaller advancement to architectural adjustments, with the 358H exchanging two performance cores for additional low-power efficiency cores within its 16-core configuration.
Intel designed the Panther Lake lineup to prioritize power efficiency over raw performance gains when matched against Arrow Lake-H processors at equivalent workloads. Early testing suggests the integrated Xe graphics may substantially outperform the Xe2-based solution found in Arrow Lake-H systems.
