Following on from the B580 video, I got hold of an Intel Arc A380 for around 100 quid well £129 on amazon uk at the momment new , a 6GB card, no external power needed — to answer one question: do the older A-series Alchemist cards work in SteamOS too? The answer is yes. All of them should. And that opens the door for a lot of people.

WHY THIS MATTERS
The B580 proving SteamOS runs on Intel was one thing. But the A-series cards are where it gets interesting for budget builds. A brand new A380 is about 150 quid. A used one is 100. The 16GB A750 and A770 are being flogged cheap because nobody knew what to do with them. If they all work in SteamOS — and this test says they do — that's a whole tier of dirt-cheap gaming hardware suddenly viable.
THE TEST
Arc A380 6GB on SteamOS, benchmarked against a CachyOS laptop and a base Arch laptop, both running an RTX 3050 6GB with a Ryzen 9 7945HX. So the A380 is going up against a far more powerful laptop chip and an Nvidia card with DLSS. Not a fair fight on paper.
The RTX 3050 laptop edges ahead, CachyOS pushing slightly in front as usual. But keep perspective — that's a 100 quid 6GB card going toe to toe with a premium laptop chip and an Nvidia GPU, and landing within a handful of frames. All on low settings with FSR, because XeSS still doesn't work properly on Linux — it falls back to a slow software mode, so always use FSR.
FRAME PACING
This is where it gets good again. Despite the lower frame rates, the A380 on SteamOS beats the others on frame pacing across almost every game. Homeworld 3 and Cyberpunk are noticeably tighter. Returnal is neck and neck. Only Black Myth Wukong was wonky and I may retest it.
That's the point — because the frame pacing is so tight, that 40-50 FPS actually feels smooth. No stuttering, no juddering. For a 100 quid gaming card, 40s and 50s delivered smoothly is genuinely playable.
THE HEADLINE — ALL XE CARDS SHOULD WORK
If it works on the A380, it works on the whole Alchemist A-series. And it's not just discrete cards — someone pointed out the Iris Xe integrated graphics in things like the NUC 12 use the same architecture as the Alchemist cards. So mini PCs and boxes with Intel Xe graphics may be able to run SteamOS too. Any Intel Arc Xe graphics should work straight out of the box.
PUSHING IT FURTHER
6GB is limiting and you're not getting much headroom, but you could probably squeeze more out of it with Lossless Scaling — the little plugin you can buy. I own it but haven't tested it on Arc yet. That might get you over 60 FPS if you wanted to push it.
WHY THIS IS BIGGER THAN THE STEAM MACHINE
This opens SteamOS to people who don't have cash for a big Nvidia card and didn't go AMD. They bought an Intel Arc card, wondered what to do with it, and now they can flip to SteamOS and just play games. Well done Valve.
And when Nvidia support lands — which Valve has confirmed is coming — that's the real game changer. Nvidia holds 70-80% of the GPU market. Right now those users have to go the Bazzite route with all its layers. Pure SteamOS with that frame pacing is a far better experience. Once Nvidia works, the Windows exodus gets a lot bigger.
The headline is Arc. If you've got any Xe-based Intel card sitting around, you can build a SteamOS gaming machine with it.
