GeForce is clocked at 120 MHz, thus the pixel fill rate of GeForce is four pixels times 120 million per second = 480 Mpixels/s. Therefore GeForce's texel fill rate is 480 Mtexels/s. Now since GeForce2 is clocked at 200 MHz, four pixel pipelines sum up to a pixel fill rate of an impressive 800 Mpixels/s Due to the 'Hyper Texel Pipeline' however, the texel fill rate of GeForce2 is even better. Getting back to the impressive fill rate numbers of GeForce2 GTS we should realize that it does not only mark the leader in the 3D arena for some time to come, but also that it represents an improvement of 66% in pixel fill rate and 333% in texel fill rate over its predecessor GeForce....

If it had the claimed fill rate it would kick GeForce2's butt. However, its 16-bit fill rate is closer to 500 Mpixel/s and its 32-bit fill rate just above 200 Mpixel/s. We have just learned that even chips with the highest theoretical fill rate can't deliver due to memory restrictions, so that claims of fill rates above 600 Mpixel/s can only be sustained with either a memory bandwidth way above 5.3 GB/s or a new technology that avoids unnecessary accesses to memory. HyperZ reduces memory bandwidth requirements at the same time as it limits the waste of fill rate for pixels that are not supposed to be displayed. Radeon is the first 3D chip of the year 2000 that can actually live up to its (admittedly modest) fill rate claims. ...

Fill Rates One item you can see advertised on the side of a graphics card's packaging is the fill rate. The fill rate is generally referred to as the rate at which a graphics processor can draw pixels. However, there are generally two forms of fill rates: the pixel fill rate and the texture fill rate. As described above, the pixel fill rate is the total number of pixels the card can output and is calculated as the number of raster operations (ROPs) multiplied by the clock frequency. The texture fill rate is calculated differently by ATI and Nvidia....
