DIY Steam Machines Are Here: SteamOS Now Supports Any AMD Graphics Card Valve's SteamOS compatibility list now includes discrete AMD GPUs, meaning anyone with an AMD Radeon card can build their own Steam Machine without paying the $1,049 entry price for Valve's first-party hardware. SteamOS 3.8.10, released June 17, formally extended the operating system's support to off-the-shelf desktop PCs with Intel or AMD processors and any AMD graphics card.
The timing is deliberate. Valve's official Steam Machine launched this month at $1,049 for the 512GB model and $1,350 for the 2TB version, pricing that drew sharp criticism from reviewers.
Linus Tech Tips called it "an enthusiast price" and argued the PlayStation 5 delivers better value. A global RAM shortage forced Valve to ship some units with a single 16GB memory stick instead of dual-channel configs, further denting performance.
Valve's Pierre-Loup Griffais told Digital Foundry that "SteamOS is ready" for DIY builders. The intended setup is a TV-connected PC on a single dedicated drive, running the SteamOS gaming interface with a controller.
Valve says the experience now matches a Steam Deck connected to a display or an official Steam Machine.
Digital Foundry published four build configurations ranging from $783 (a budget AM4 Micro ATX build with a Ryzen 5 5600 and RX 9060 XT) to $953 (an AM5 Mini ITX compact build). All three AMD-based configs come in under the Steam Machine's $1,049 price tag, with the premium compact build expected to outperform Valve's own hardware.
NVIDIA GPU owners are stuck waiting. Valve software engineer Pierre-Loup Griffais confirmed in an interview with The Verge that a dedicated engineering team is collaborating with NVIDIA on driver support. But the work is structurally complex: SteamOS uses an immutable filesystem that cannot accommodate NVIDIA's proprietary userspace drivers the way standard Linux distributions do.
Multiple outlets characterized the timeline as not before late 2026, with 2027 seen as more realistic. For AMD users today, the path is functional.
SteamOS 3.8.10 ships with Linux kernel 6.16, updated Mesa graphics drivers, improved video memory management for discrete GPUs, and support for Variable Refresh Rate over HDMI. The recommended GPU pairing is an AMD Radeon RX 6000 or RX 7000 series card, with RDNA 4 support available through the kernel and Mesa versions included in the update.
Component costs still bite. Asus Systems Business General Manager Liao Yi-hsiang told Economic Daily News that PC product prices will see single-digit increases in the third quarter, a slowdown from the 300%-plus surge in RAM and 40% increases for PC systems over recent months.
Griffais acknowledged that a DIY Steam Machine will not always undercut Valve's pricing when buying new parts, but for users with existing compatible hardware, the option now requires no reservation.
Valve manufactured only roughly two-thirds of its intended Steam Machine supply, with AI data centers consuming most available components. Reservations close June 25 at 10 AM PT, with shipping beginning June 30. The DIY route sidesteps that lottery entirely.
Remaining limitations: Secure Boot must be disabled for installation, and kernel-level anti-cheat systems used by titles like Valorant, Call of Duty, and Battlefield remain incompatible with SteamOS regardless of GPU. Valve has said it is working on anti-cheat support but has offered no timeline.
