Notes
  1 - All GPU vendors use a unified architecture for their DX10 chips - this means execution units are used to process all kinds of components (vertex, geometry and pixel).  Previous architectures had    pipelines of units dedicated for each type of component.
  2 - The ATI Radeon HD 3870 X2. 4850 X2, 4870 X2 and NVIDIA GeForce 9800 GX2 and GTX 295 are composed of two GPUs.  The performance figures are calculated for when operating in AFR (alternate frame rendering) mode.
  3 - The complete G80 chip has 32 texture addressing units and 64 units to fetch and bilinear filter texels; the complete G92 chip has 64 addressing and fetch/filtering units.  This is why there is a significant difference in the "texel applied rate" between the two processors.
  4 - The RV770/RV790 has 32 fixed function interpolators, the RV730 has 16. The displayed texture fillrate figures reflect the impact the interpolators have on the theoretical maximum values.  When using AF, however, this limitation does not restrict the texturing ability.
