One of my great disappointments with NVIDIA’s Fermi is that we know it has 512 streaming processors. Unfortunately, none of the graphics cards, whether for professional or gaming purposes, that have been released by NVIDIA enable all of these streaming processors. The GeForce GTX 480 has only 480 streaming processors. In the professional realm it is even worse. The Quadro 6000 has only 448 streaming processors.
A user over in the [H]ardOCP forums has collected some nice NVIDIA GeForce GTX 580 rumors. Among those rumors are that the GeForce GTX 580 will have all 512 streaming processors enabled.
