Steam Machine Specs (2026): Every Part Explained Simply
The short answer
What is the processor and why does it matter?
The processor is the brain of the machine. The Steam Machine uses a custom 6 core AMD chip (the Zen 4 design) that runs at up to 4.86 GHz.
In everyday terms, this is a modern, capable brain. It is noticeably stronger than the one in the Steam Deck, which means it can keep up with today's bigger games and still handle background tasks without slowing down.
What about the graphics?
Graphics are what draw everything you see on screen. The Steam Machine has an AMD graphics chip with its own 8 GB of dedicated memory.
Here is the part that matters most: that graphics memory is the chip's own, not shared with the rest of the system. That helps games load detailed textures and keeps the picture steady, so things look sharp and play smoothly on a TV.

How much memory and storage do you get?
Memory (RAM): 16 GB. This is the short term work space your games use while they are running. 16 GB is a comfortable amount for modern gaming.
Storage (for installing games): you choose one of two sizes.
- 512 GB for $1,049, a good amount for most people
- 2 TB for $1,349, if you like to keep a lot of big games installed
If you fill it up, you can pop in a microSD card for extra room, the same way you might in a phone or a Nintendo Switch.

How does it connect to the internet and your gear?
The Steam Machine has fast modern Wi-Fi, Bluetooth for wireless controllers and headphones, and a wired internet (Ethernet) port for the most stable online play. The exact list of ports on the back will be confirmed by Valve at launch.
Is this better than building my own PC?
A do it yourself mini PC with similar power usually costs somewhere around $700 to $900. So the Steam Machine asks for a bit more money. What that extra buys you is no building, no setup headaches, and software that is ready to go the moment you plug it in.
Curious about the trade offs? We laid them out in the Steam Machine vs build your own PC guide.
What software does it run?
It runs SteamOS, the same simple, controller friendly system as the Steam Deck. You turn it on and you are looking at your game library, no desktop to manage.
SteamOS is based on Linux, and it uses a clever tool called Proton to run games that were made for Windows. The large majority of Steam games work this way. If you ever want to check a specific game, the community site ProtonDB tracks how well each one runs.
