We Built he Fastest All-AMD RDNA4 Steam Machine! Insane Performance

In this video, we're taking a look at official SteamOS 3.9 running on the most powerful all-AMD small form factor gaming PC I’ve built in a long time. We’ve got the AMD Ryzen 7 9800X3D paired with an RDNA 4 Radeon RX 9070 XT inside an M3 Mini-ITX case — and performance shocked me. Running SteamOS on RDNA4 has been impossible until now, but with Valve’s latest main branch release, everything finally boots and works correctly. So in this video we put it to the test with Cyberpunk 2077, Spider-Man 2, Witcher 3, Marvel Rivals, God of War: Ragnarok, and Borderlands 4 — all at 1440p and 4K Ultra.
