"To summarize, the pixel pipelines of the NV40 have been redesigned, and there are now 24 of them (as opposed to 16). Pixel processing power has increased two-fold over a GeForce 6800 Ultra. The number of vertex shaders has also been increased – from 6 to 8. A number of other tweaks were also implemented in the FP HDR, geometry setup, and anti-aliasing units."
