Very similar for me on kernel 6.5.9-arch2-1. A bit lower on video playback in firefox, 14-16W. PPD or TLP does not make a whole lot of difference, but I decided on PPD as recommended. GPU and CPU seem to clock down correctly, removing all extension cards does not change the power use. My installation is a swaywm desktop with pretty minimal background tasks running.
Maybe SSDs not entering power save modes could be a factor? I do not know how to check that. I’m currently using a WD SN850X.
Edit:
Found lspci -vv | grep 'ASPM.*abled;'in the Arch wiki.
echo powersupersave > /sys/module/pcie_aspm/parameters/policy
turns some of the “Disabled” entries into “Enabled” and that seems to reduce power use a bit. This is not persistent between reboots and I do not know if it has negative implications.
