Valve has released the full technical breakdown for the Steam Machine, and this thing is a serious jump over the Steam Deck. Valve themselves have said it delivers around six times the performance of the Deck, which gives you a rough sense of the upgrade without needing any guesswork about frame rates or game-by-game results.

Where This Sits in the Real World
Valve’s six-times-Deck claim already paints the picture. On paper, the raw numbers place the Steam Machine slightly under a PS5, but the updated architecture and fixed hardware profile should put it closer than people expect in actual use. That’s without making any promises or trying to call performance before review units land.
Once hardware is in the wild, we’ll look at the real stuff that matters:
• how AAA ports behave
• how far it can push 1440p and 4K
• thermals
• noise
• Deck vs Machine comparisons for older games
• TV play and SteamOS improvements
But for now, these are the specs, clean and simple.
