But the per-watt performance of these chips is usually terrible, made as they are on older silicon processes. Any recent-ish laptop CPU will have no problem beating them.
It's successor arch, Meteor Lake has only recently launched, so the N100 shouldn't be too far off in terms of efficiency.
In lower power scenarios the little cores can be more efficient than the large ones. And at 6W TDP the N100 is a low power scenario. https://chipsandcheese.com/2022/01/28/alder-lakes-power-effi...
