Steam On Linux Falls Short Of 2% For January, AMD CPU Adoption On Linux Hits 70.5% by Michael Larabel (phoronix.com)
The Steam on Linux marketshare per Valve's official survey put it at 1.97% for December after hitting 1.91% in November -- continuing a slow upward trajectory seen in recent months thanks to the ongoing success of the Linux-powered SteamOS / Steam Deck ... In turn the CPU results for AMD continue to climb for Steam on Linux use in part due to the Steam Deck. AMD CPUs power 70.5% of Linux gaming systems on Steam.

I did my part to contribute to the positive Linux and Linux-AMD trends. My workstation has an AMD CPU. However, my mini TV-designated PC and laptop, both of which have Steam (although I never really run Steam on them), run Linux with Intel CPUs.
