Valve beats down the rumors with a crowbar.
When the prototype Steam Machines’ specs were released, they all had Nvidia GPU’s. This sparked rumors that Nvidia might have an exclusivity on the rigs. However, Valve shoots down said rumors.
Valve’s Doug Lombardi said that AMD and Intel versions of the SteamOS-powered living room machines will be revealed at a later date.
Speaking with >Maximum PC, Lombari said:
“Last week, we posted some technical specs of our first wave of Steam Machine prototypes. Although the graphics hardware that we’ve selected for the first wave of prototypes is a variety of Nvidia cards, that is not an indication that Steam Machines are Nvidia-only.
In 2014, there will be Steam Machines commercially available with graphics hardware made by AMD, Nvidia, and Intel. Valve has worked closely together with all three of these companies on optimizing their hardware for SteamOS, and will continue to do so into the foreseeable future.”
Valve and Nvidia also worked together for the SteamOS, but it seems that was nothing than a collaboration, or a deal for more Nvidia-powered Steam Machines. Who knows?
