I have several Ryzen laptops, including a 6800H. The thing is as fast as the latest and greatest from Apple, although with a bit worse battery life. I get about 12 hours in Linux with Gnome. Very quiet. The fan turns on only during gaming, or prolonged compiling.
The mobile Ryzen 7000 line is a bit messy, though. If you want the Zen 4 stuff, you need to look for a 7x4x model, such as the 7840 from this article.
7 is the generation.
4 indicates that it's a Zen 4 part. There are many 7x3x parts on the market because they are simply rebranded Zen 3 (5000 and 6000) parts.
It can be a problem with newer models. Make sure you run the 6.2 kernel or newer. Second best option would be to build the drivers yourself, assuming they are available in the first place
