AMD knocked it out of the park with its Ryzen series of mobile CPUs, but there's no question that its discrete mobile GPUs have been falling behind. The Radeon RX 7900M rights the ship by being just as powerful as the mobile RTX 4080 fur hundreds of dollars less.
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!
