The texture fillrate calculator works out the texture fillrate based on the clock speed and texture mapping units.
Texture fillrate is calculated by the equation Texture fillrate = TMUs (texture mapping units) * Clock Speed (base or boost)
This gives the fillrate in MTexels/s so you can divide by 1000 to get it in GTexels/s
Usually the boost clock is used for texture fillrate calculations in GPUs.
