These numbers are what i was expectingfrom the wall Witcher 3 power consumption

216 for 7900m309 for 4090 version

This is for about a 10% framerate difference. Though 1080p seems a bad way to compare these chips. Guessing this is other things like screen, cpu etc but still a huge difference for a chip which is suppose to be horrible with efficiency due to chiplets.

They literally isolate GPU-only power draw in the review, so you know the 4090L is pulling 161 W to the 7900M's 179 W. For 28% more FPS, not 10%

The higher power draw is mostly from the CPU. Efficiency complaints - at least for the CPU - are largely around idle power.

Raw numbers sure but 7900m is brought down by dips. Look at the chart its normally running about 10% behind.

You can really compare from wall, AMD and Nvidia measure their draws differently. Nvidia actually measures their draw, AMD does some strange estimate stuff based on measurements from other parts of the board. The furmark does test from the wall I think.

Gee I love dips in my framerate, good thing my eyes see normal framerate and turn off when there are stutters!
