Valve Says Steam Machines Won’t Be Exclusive to Nvidia

“Last week, we posted some technical specs of our first wave of Steam Machine prototypes,” said Valve spokesman Doug Lombardi. “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.”
