    Phoronix: GNOME's Wayland Session Shows Potential For Better Battery Life Than With X.Org

    While not talked about as much as raw performance and other factors, but in the recent testing of the Lenovo ThinkPad T14s Gen2 laptop with AMD Ryzen 7 PRO 5850U, it was observed that the GNOME Wayland session by default on Ubuntu 21.10 is delivering better battery life / lower power consumption than using the GNOME X.Org session...

    Well, considering how much bloat and needless legacy functionality x has, that's no wonder.

      Apart from less code bloat, Wayland also implies less context switches than x11. This is just GNOME's wayland implementation getting mature and starting to deliver on the promised advantages over x11.

        While I expected the performance difference, the 3 Watts savings is really impressive.

          It's the overall architecture of Xorg that simply sucks. Code bloat doesn't have a performance impact so much because it's just unused data consuming some storage space.

            And Ubuntu is just on Gnome 40. Pretty positive there were some performance improvements in 41.

              Michael I'd be interested in a comparison between Plasma Wayland and Plasma X.Org!

                I‘d be interested in how KDE Plasma behaves under Wayland indeed.

                  Are these tests pure Wayland ones or are they XWayland?

                    does ssh offers a Waylandforwarding like x11forwarding feature?

                    I believe Wayland doesn't have that masterpiece, very useful on servers..
