Additional Observations Part Deux

  • Use case: streaming video.

Watching Netflix with & without hw accel in Firefox. It looks like hw accel is advantageous as the gpu uses less power than cpu based rendering (thx AMD :wink: ).

Fedora is already using pipewire. Migrating Ubuntu to that seemed good for an avg power reduction of 0.5-1W. Streaming for 85 mins took 17% @ 6.6W avg. Est endurance is over 8 hrs.

Config: PPD power-saver, EPP balance_power, usb autosuspend, pipewire, FF hw accel

  • Use case: benchmarking.
    Running Furmark windowed at 1280 x 1024 and openssl RSA4096 concurrently. Maxes gpu & cpu load. 35 mins took 25% @ 23.6W avg. Est endurance 2:20.
    Config: PPD balanced, EPP balance_power, usb autosuspend

  • Currently using 6.5.0-1008-oem kernel. Looking at updates in 6.6, interested in retesting consumption. Also considering @David_Markey’s 6.7 kernel with fixups as @jwp has mentioned or running Fedora rawhide or Ubuntu mainline for additional testing.

  • Use case: large file downloads.
    powertop showed as much as 6.2W draw from the wifi card. Over time 5g throughput would taper off by as much as 50%. 2.4g was consistent, albeit expectedly slower. Seemed unaffected by status of power management via iwconfig
