For those that can't load and are curious, the M1 Max scores about 2x the Intel Core i7-11800H in the Dell laptop on both single core and multi core scores.

I don't think that was a good sample, most of the XPS 15's I see have a much higher single thread score, almost double the one linked above:

It looks like the original as been updated, the differences don't seem very drastic especially when you consider what the SKU's w/ the m1 max cost

guess it's about a 1.5-2x difference in battery life though

I think there is a big variance in XPS 17 scores. For reference, here is a top scoring XPS 17. In this case, scores are much closer.
