Once again, the Core Ultra X7 358H was benchmarked, but this time we have a much more reliable benchmark platform than Geekbench.
Core Ultra X7 358H is 15% Slower Than Core Ultra 7 265H, while its iGPU is 23% Slower Than GeForce RTX 3050 Laptop GPU, according to PassMark
We have new benchmark numbers for one of the upcoming Intel Panther Lake SKUs, and this one has been the most prominent in the leaks. The Core Ultra X7 358H, which is a mid-range mobile CPU was benchmarked on PassMark, revealing that it's noticeably slower than the current Intel Arrow Lake-H chips. The CPU scored 4,282 points in the single-threaded test and 29,426 points in the multi-threaded test.
The result page confirms that the CPU boasts a 16-core configuration (4+8+4) and has 18 MB of L3 cache as was previously seen in various leaks. Clocks aren't disclosed yet, but coming to the scores, we see that the single-core performance is slightly slower than the chips like Core Ultra 7 255H and 265H, which deliver 4,347 and 4,433 points. In the multi-threaded test, the Core Ultra X7 358H is 4% slower than the 255H and around 15% slower than the Core Ultra 7 265H, which is somewhat significant.
Keep in mind that this is an early engineering sample, and the final results may vary. That said, we also have its iGPU scores, which we previously saw on Geekbench. Unlike Geekbench, PassMark is much more reliable in terms of CPU and GPU performance comparison. Here, we can see that the Intel Arc B390, which is based on the Xe3 architecture, delivers 9,339 points. Compared to desktop budget GPUs, it's closer to the GTX 1650 Super, but compared to the RTX 3050 laptop, it's 23% slower.
This is quite different from the last benchmark, where the Arc B390 was going head-to-head with the RTX 3050 Ti laptop GPU. Once again, take these numbers with some caution, as these are based on early engineering samples. Nonetheless, the scores do not look impressive, and it will be really disappointing for Panther Lake to lose to Arrow Lake. Panther Lake is coming in January 2026, and it's going to appear only on the mobile platform. If it doesn't offer impressive performance, Intel will have to take care of its Nova Lake lineup, which should be coming in late 2026.
