Need to confirm the fps, it could be using less power because it's receiving less work to do.

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I agree, that's why I said I'd need to retest on W11 to confirm. I'm really going based on the clock vs power used behavior. The card consistently clocks higher within the same power budget on Linux.
I don't know how accurate the reported clock speeds from Mangohud are though.
IDK how big the performance vs Windows is exactly... FPS wise. All games seem to run really well and roughly in the same ball park.
The frame pacing on Linux is immaculate though. At least in the games I play and tried.
You need the number over time, and to confirm the same features are used, ie whatever Ray tracing or other effects.
This is hard to measure and confirm, could be more efficient, could be lower settings.
I applaud you investigating though!
It's really bumming me, I'll try to throw W11 back on a spare SSD if I'll get some more free time and test this.
I've spent quite a while benching and tinkering with the card and monitoring on Windows so seeing the monitoring results on Linux deviate this much from what I expected is interesting to me.
I need to think of some good games to try this on, games that offer results which don't deviate too much for simpler testing.
Yes, different drivers mean that could be possible. Run the same benchmark under both Windows and Linux if you want comparable data.
Absolutely had this with an older card on a laptop years ago The windows drivers no longer got the same updates but Linux was recent within the same month and certain games performed significantly better in Linux+Wine than Windows as a result
Idk about more efficient, but more performance? Yes. I've had 2 AMD cards now and both of them perform noticably better on linux than on windows
Did you measure this on the wall or in software? Dhe latter is not accurate nor comparable between OSs.
In Software. But I have an UPS that shows power used so I'll log both if I'll get to testing
