My desktop with KDE Plasma 5 consumes somewhere in the ballpark of 500 MB RAM initially on startup. RAM consumption by Konsole, tmux, and Neovim (30+ loaded buffers) combined is negligible to say the least. RAM consumption by my browser with 10+ windows and 100+ tabs loaded easily exceeds 4+ GB even when exclusively visiting supposedly "lightweight" text based sites (ie documentation). Going beyond RAM, playing a video on YouTube occupies a small but noticeable fraction of total CPU time. A single script heavy ad laden site sometimes manages to occupy a problematically large fraction of all available cores. Depending on the site, Dark Reader might slow this all to a crawl for 10+ seconds as the bloated page gradually loads (I'm looking at you, Amazon). The problem isn't modern desktop environments.
