Prototypes of Valve's Steam Machine consoles, which were seen last week used Intel CPUs and graphics chips made by Nvidia. But a spokesman for Valve Software has confirmed that future designs will use AMD graphics.
At the time of the launch there was a confusing statement from Steam. It said that the graphics hardware which had been selected for the first wave of Steam Machine prototypes included a variety of Nvidia cards. However it warned that it was not indication that Steam Machines are Nvidia-only.
Now it seems that it has clarified that position by saying that there will be Steam Machines with graphics hardware made by AMD, Nvidia, and Intel.
Valve has worked closely with all three of these companies on optimising their hardware for SteamOS, and will continue to do so into the near future, the spokesman said
What is still not clear is if the Steam Machines would actually use AMD's microprocessors, or just still to Intel's creations.
The Steam Machines are Valve's attempt to create a working console. It has also released a large number of different specs with varying hardware.
The company thinks that there will be a significant percentage of Steam users would actually want to purchase—those who want plenty of performance in a high-end living-room package. Others will want budget machines, or super quiet versions.
When the specs came out, many were surprised that AMD was not included because of its strong presence in the graphics and games market. AMD chips had also been under the bonnet of both the Sony and Microsoft consoles.
This led PC World to get onto the blower and ask AMD why it been excluded from the Steam Machine programme.
AMD confirmed that it had been actively engaged with Valve on these products and campaigns. Valve has not named the AMD GPUs which will be used.
