Phoronix recently conducted tests on Ubuntu 26.04, comparing the performance of the KDE Plasma 6.6 desktop with its Wayland session against the default GNOME 50 desktop. The analysis indicated a notable performance advantage for KDE Plasma 6.6, particularly when utilizing AMD Radeon graphics across various games and graphics workloads. The testing highlighted that Plasma 6.6 delivered improved frame rates and smoother operation in these scenarios. For users with AMD Radeon hardware, Plasma 6.6 is "in quite impressive shape for the upcoming Ubuntu 26.04 LTS release," as stated by Phoronix, suggesting a beneficial experience for that platform and desktop environment combination.
