What's a Pixel Fill Rate?

[63]

I'm sorry for this noob question, but it's really buggin me! the 9600 has a 1.6 fill rate, and the 9800 has a 3.04 (I think), can anyone tell me waht this realy means?

I don't know the "exact" meaning but I do know the higher the number, the better.

I think it's how many pixels can be displayed per frame but I really have no idea.

Well if it was pixel fill rate it is how many pixels it coudl draw in a second. This determines the upper limit of hertz per resolution

1024x768 = 786,432 pixels per per frame
to execute 72 hertz (72 frames or updates per second) = 56.6 Megapixels/second

1600x1200 = 1.92 million pixels x 72 hertz = 138.24 megapixels/second

However I think the fill rate you are looking at is triangle fill rate. Complex graphics in games break all polygons in the scene into triangles (a basic building block for 3d rendering). Higher fill rates make it capable of rendering a more complex scene quickly.
