Nvidia's G80 has 32 pixel pipes

16 vertex & geometry Shaders

IT TURNS that the fancy Nvidia G80 chip taped out, and in working silicon stage it will have 32 pixel Shaders and, as predicted, have 16 vertex and geometry Shaders.

Nvidia wants to stick with a two to one ratio and assumes that the games of tomorrow will need twice as many pixels than they will need vertices and geometry information.

ATI believes in a different religion. ATI believes that every Shader should become one, united and bellowed. No more segregation to Pixel and Vertex Shaders. If ATI makes a chip with 64 Shader units all of them can do Shader either vertex or pixel or geometry stuff all the time. You can check the stories at the bottom for a better explanation.

We don't know the clock speed of the upcoming performer but we don't believe Nvidia can get more than 700MHz out of it - we could be wrong about that. µ
