The Core Ultra X7 358H processor, recently featured in the Samsung Galaxy Book6 Pro laptop, has now appeared in the PassMark database, allowing us to compare its performance with other CPUs. Although PassMark is a specific benchmark, it’s currently the only one available.

The new 16-core chip (with a core configuration of 4+8+4) scores 4282 and 29,426 points in single-threaded and multi-threaded modes, respectively. These are far from record-breaking figures. For comparison, the 16-core Core Ultra 7 255H achieves similar results, while the 265H scores 4433 and 34,678 points.

Firstly, it’s worth noting the single-threaded performance. It hasn’t improved compared to the Arrow Lake results, although the Panther Lake series is based on the new generation of large and small cores with different architectures. Expectedly, the multi-threaded performance hasn’t increased either, when compared to the Core Ultra 7 255H. However, the latter has a 6+8+2 configuration, which means two more large cores, suggesting that Panther Lake is somewhat more efficient per core. It’s important to understand that the tests involved a non-retail sample, and the performance might eventually be higher, although not significantly.
The critical point is that Intel hasn’t promised high performance, but high energy efficiency, which we cannot evaluate here.

Benchmark results also include iGPU performance. The Arc B390, with 12 Xe3 cores, scores 9339 points against 10,188 and 12,144 points for the GTX 1650 Super and RTX 3050 Laptop, respectively.
