Steam on Linux managed 2.57 per cent marketshare for June 2025, down just 0.12 per cent from May’s record of 2.69 per cent. Despite the slide, it’s still looking solid compared to this time last year when Linux sat at 2.08 per cent.

A good chunk of that growth has been driven by the Steam Deck, which runs Valve’s SteamOS Holo and now accounts for roughly a third of Linux gamers. With more handhelds jumping on the SteamOS bandwagon, that number is only heading in one direction.

On the CPU front, AMD has officially taken over with a whopping 69 per cent share among Linux users. No surprise really, considering the Deck’s custom AMD APU and the open-source friendliness that keeps Linux punters loyal. For contrast, the Windows side of Steam still leans Intel, with Chipzilla holding 60 per cent against AMD’s 39 per cent.

AMD holds the graphics crown among Linux gamers, thanks to solid open driver support and Nvidia’s continued ambivalence about not being a total nightmare on open platforms.

So while Linux on Steam may have dipped a smidge, it’s far from fading. If anything, the Deck effect and AMD’s hardware love-in mean the penguin-powered platform is still marching forward.
