Maybe he meant homogeneity which Nvidia did try and tries with Arm.. but, on the other hand how wild would it be for Nvidia to enter x86-64 as well? It's probably never going to happen due to licensing if nothing else, lest we remember nForce chipset ordeal with intel legal.

Indeed, but I think people forget that the reason AMD have a license in the first place was because Intel's customers in the early days required a second source for it's processors.

Who owns the Cyrix x86 license these days?
