Default Re: why do fx cards perform so badly in 3dmark05

Increase from 5 to 6vp => 100

The word limited is, to be honest, also incorrect as it implies it is stopping the score going up. This is not the case, even with 4VP at 16 pipelines you get 600 points more than 6vp at 8 pipelines .

It would be more accurate to say that 3dmark05 is both pixel and vertex dependent but with pipeline quads being more important.


Oh jeez, you're getting bent out of shape over a techicality? The whole point of the chart was to show that 3dmark is sensitive to vertex performance and its not entirely a pixel shaded limited demo, In which case, This hasnt changed a bit,

of course 4 pixel pipelines is going to have a dramatic increase on effect, you gain 4 shader dedicatedt shader units +4 shared shader units with 1 quad activation, You only lose 1 vertex unit by disabling vertex performance.

And no this is not a 6800NU, If you look at the chart it clearly labels it a GT.
