That could explains why I only got about 300-400 point more when I enabled the extra 4 pixel units on my BGF 6800 OC.
I wonder if higher clock speed will reduce the difference?
to me this implies a bandwith restriction even on the shader units, It makes me wonder if even the Nv4x series are seeing diminishing returns at 16 pipes (compared to 8x1 to 12x1) I wonder how bandwith limited the X800 is.
Which would of course raise several other questions, Clock effiency, Shader efficiency, ect
