You can read the whole article here. AMD is now on the clock, though given Win 10 2004's issues, it's a slow clock.

But I will post this excerpt, as it's likely going to be applicable to AMD as well. It looks like in Win 10 2004 the GPU choice page is integrated into Windows Settings itself instead of being preset in the GPU's software programs, which will be helpful for mixed mobile systems which have, say, an AMD or Intel APU, which you wouldn't install anything but the driver for, and a dedicated nVidia GPU.
WCCFTech did a quick comparison in two games, Gears Tactics and Forza Horizon 4. There isn't much difference on the 2080Ti, although with its 11GB VRAM it's to be expected, so I won't post that chart. The GTX 1650 Super, however, with its 4GB VRAM, shows distinct improvement. It will be interesting when tests are expanded to a couple dozen games and more cards to see if this kind of uplift is seen across the board, especially the upper midrange 2070/5700XT where 8GB VRAM is starting to become a real limitation, but a free 8% improvement isn't anything to sniff at.

TomsHardware's test results on this have shown mixed results, effectively no net gain.
