Here’s a bit of news to warm the hearts of Radeon fans everywhere. AMD GPUs will be included in next year’s batch of Steam Machines. We can’t say we weren’t expecting this, but Valve’s original announcement did not mention AMD at all – it was all Nvidia.

The announcement caused plenty of controversy, as many speculated that Valve is basically focusing on Nvidia hardware and that its SteamOS gear won’t feature any AMD hardware. This is clearly not the case and Valve is moving in to squash the rumourmongers.

Valve’s Doug Lombardi told Forbes that the first wave of Steam Machine prototypes includes a variety of Nvidia cards, but he stressed that it 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,” he said.

So much for conspiracy theories peddled by the usual suspects.

But why didn’t AMD or Valve respond a bit earlier? Forbes speculates that the entire mess could have actually benefited AMD, which is set to hold a quarterly earnings call on October 17. On top of that there is the Origin controversy.

We are not in the conspiracy theory business, there’s clearly plenty of stuff going on behind the scenes but there’s no reason to jump to conclusions.
