Nope this is purely from a broken test. Watch the video and you’ll see that its not testing with the same power limits.
17w tests are actually 16w vs 20w+ and 35w test is 25w vs 35w
This leads to drastically higher clock speeds on both cpu and gpu as seen in the video and thus higher fps (and power draw, so lower battery life)
They are supposed to have the same settings, the Linux ones are just wrong and using more power than told It’s supposed to be capped to 17 but pulling over 20 vs 16 on windows. That’s a lot more lower resulting in higher fps but lower battery life.
It’s bad test.
Watch the video the tdp, clock speeds for cpu and gpu are much higher on Linux which accounts for the differences
I had an all in one a decade ago (think epson?).
I couldn’t scan a document because it was low on some color.
