Sony used Nvidia to power the graphics of the current generation's PlayStation 3, while Microsoft uses AMD in their Xbox 360 and is expected to use them again for their next Xbox.
The note comes via former AMD employees, says Forbes.
Both companies declined comment, and Sony went as far as to not even acknowledge that the PS4 is coming, at all
While the move would be significant, the report must be taken as speculation as moving to a custom AMD Radeon graphics chip would likely kill backwards compatibility with PS3 games, says Xbit, unless Sony pays dual royalties to AMD and Nvidia.
