3D rendering
GeForce 8 performs significantly better texture filtering than its predecessors that used various optimizations and visual tricks to speed up rendering while impairing filtering quality. The GeForce 8 line correctly renders an angle-independent anisotropic filtering algorithm along with full trilinear texture filtering. G80, though not its smaller brethren, is equipped with much more texture filtering arithmetic ability than the GeForce 7 series. This allows high-quality filtering with a much smaller performance hit than previously.
NVIDIA has also introduced new polygon edge anti-aliasing methods, including the ability of the GPU's ROPs to perform both Multisample anti-aliasing (MSAA) and HDR lighting at the same time, correcting various limitations of previous generations. GeForce 8 can perform MSAA with both FP16 and FP32 texture formats. GeForce 8 supports 128-bit HDR rendering, an increase from prior cards' 64-bit support. The chip's new anti-aliasing technology, called coverage sampling AA (CSAA), uses Z, color, and coverage information to determine final pixel color. This technique of color optimization allows 16X CSAA to look crisp and sharp.Sommefeldt, Rys.NVIDIA G80: Image Quality Analysis, Beyond3D, December 12, 2006.
The claimed theoretical processing power for the 8 Series cards given in FLOPS may not be correct at all times. For example the GeForce 8800 GTX has 518.43 GigaFLOPs theoretical performance given the fact that there are 128 stream processors at 1.35 GHz with each SP being able to run 1 Multiply-Add and 1 Multiply instruction per clock (2 FLOPs) + MUL (1 FLOP))×1350MHz×128 SPs ＝ 518.4 GigaFLOPs. This figure may not be correct because the Multiply operation is not always available giving a possibly more accurate performance figure of (2×1350×128) = 345.6 GigaFLOPs.
