AMD just announced the Ryzen 6000 CPUs will move to the Navi2 GPU (as in Radeon 6000 series. The first laptops with this CPU has already been announced (Lenovo, Asus, IIRC). There will be -G CPUs (like the current 5x00G and 4x00 Pro too with integrated graphics.
How well they perform remains to be seen, as it depends on how many compute units or cores or whatever they fit in, but even the previous gen CPUs which had the much much older Vega graphics, wiped the floor with the best Intel had to offer in the graphics department. So this should be good.
For what it's worth, I have both the 6900XT (Navi2) and 3080 (Ampere) GPUs. They perform roughly similar. nVIDIA is a little faster in somethings, AMD in others, with the balance being on AMD's side (I think the 6900XT really fits in between the original 3080 and 3090 - I can't comment on the Ti models), but it runs a fair bit cooler, and thus lower power usage. Just my (limited) experience so far - YMMV
