On the official framework guide for their AMD boards they say that you cannot use TLP / Powertop. You have to use the stock Power Profiles Daemon with Kernel 6.5.6 or greater. That nets the best results right now. Seems like TLP messes things up pretty bad as per some users on the Framework forums.

NOTE that TLP is recommended by them for Intel builds but not for the Pheonix based builds specifically

This is highly dependent on your machine and configuration.

I just got a framework 13 AMD with the 7840U chip. Seems to idle around -4-5W of total system power. Minimal loads with browsing etc will be around 7-8 watts. Windows still seems to be better optimized but it’s not bad at all considering.
