I would recommend the Intel X7 358H over the AMD because of the latest gen efficiency improvements that should lower heat and increase battery life compared to all the AMD options. I do not really know how these compare in terms of performance and even if they outperform the M5 (which shouldn't be too hard)
I'm puzzled by choosing that particular Intel processor. It is not particularly fast in either single or multi-threaded performance. The Intel Ultra 9 290HX Plus would be a tougher competitor.
Passmark, for example, says:
Overall Rank:
452nd fastest in multithreading out of 5872 CPUs
164th fastest in single threading out of 5872 CPUs
48th fastest in out of 1626 Laptop CPUs
Apple M5 and M4 processors are significantly faster in single threading, and among laptops, in multithreading, many Intel, AMD, and Apple processors are faster. Laptop processors
And, it actually is quite difficult to outperform the M5. So, I'm not really sure I understand the point you were making?
