Right, unfortunately, was limited by the laptops I have on-hand for (re)testing... With routinely re-testing all laptops fresh, in this case on Ubuntu 25.04, not able to compare to prior dGPU-enabled laptops that since had to be returned to vendors, etc.
It makes sense, just leaves the article feeling kind of incomplete as a result. It's more like a data point to be compiled against other existing data. They could pull more clicks if they either had some of that other data done in house or collaborated with some other shop that does have the data (or a laptop to loan) readily available.
Phoronix just doesn't do much mobile dGPU testing in general to have any data to compare with there.
