Nvidia CEO Jen Hsun Huang revealed at a semiconductor conference that Nvidia is working on not one but two chips for Xbox. Up to this point, it was known that Intel would be providing the console's CPU and Nvidia the graphics processor, but this was the first that outsiders had heard of anyone developing a third chip for the console. Although Microsoft has revealed that the console will feature a custom 3D audio processor, no announcement of a supplier for that technology has yet been made, leading some to speculate that Nvidia may be dipping its feet in the audio chip market. Other speculation suggested that the second Nvidia chip would be handling more advanced video functions to complement its GPU. Microsoft did not comment.
