This pixel fillrate calculator works out the pixel fillrate based on the base or boost clock speed and the ROPs. There are two pixel fillrates which differ depending on if you use the base clock or boost clock in the calculation.

The pixel fillrate of a GPU is given by the equation Pixel Fillrate = ROPs * Clock Speed (base or boost).

The Pixel fillrate is given in MPixel/s when using the clock speed in MHz so you can divide this number by 1000 to get it in GPixel/s

Example Calculation

The Nvidia GeForce RTX 4080 has a boost clock of 2505 MHz and 112 ROPs. Therefore the pixel fillrate is 2505 * 112 = 280,560 MPixel/s or divide by 1000 to get 280.56 GPixel/s
