In some power constrained scenarios that sort of thing is often petty reproducible.

Especially if the different SKUs have different power budgets. Laptop GPU naming and performance is a bit of a mess, as in the example shown (the 4060 on the Asus TUF Gaming A16 has a limit of 140w GPU+CPU, while the 4070 on the Asus Proart PX13 has 115w GPU+CPU - and even that is a "custom" non-default mode with 95w being the actual out-of-the-box limit).

With wildly varying power profiles laptop graphics need to be compared by chassis (and the cooling/power supply that implies) as much as by GPU SKU.

That just proves the point about the source, right?
