The M2 Ultra will definitely crack the top 20 but it's no surprise a 24 core option is beat by 64 core competition, which tops that chart. Usually their performance claims are about previously available x86 Mac workstations, not x86 in general. You could even go beyond that chart and look at dual socket AMD to get 192 cores, you just won't be able to run a supported macOS on it.
Their more traditional "vs the rest of the industry" performance claims on laptops aim towards the single thread performance of M2. While maybe not a chart topper a year later, it's quite a far cry from the 2.5x difference you've found there. In the end though, if all you want is the fastest, loudest, most plugged in laptop you can just go out and buy a laptop chassis which accepts desktop CPUs from the likes of Clevo et al.
