NVIDIA's next-generation Fermi-based graphics chipset, the GeForce GTX 580, was said today to be shipping in late November or early December. The design is estimated to be about 20 percent faster than a GTX 480. It would be followed by 2011 releases of mainstream cards using the GF112, GF114 and GF119 architectures, which would mostly pare back the GF110 architecture the GTX 580 will use.
