NVIDIA’s next generation Fermi based graphics chipset, the GeForce GTX 580, will be shipping in late November.
The new design is shoould 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.
Most of the performance difference is due to a huge leap in the number of texture units; from 60 in the GTX 480 to 128 in the GTX 580. Teh 580 will have at least 512 shader (visual effect) cores from the current 448. A 512-bit memory bus and GDDR5 memory would supply extra bandwidth.
