Calculatin FLOPS of GPU

How to Calculate FLOPS (floating point operations per second) of GPU

or How to Calculate GigaFlops of GPU

For this You should know

1.Clock Speed of the GPU
2.No of mul-add (ALU that can perform both mul and add in one clock second) units, nof of mul units
3.No of SIMD units
4.No of Cores
Max GFLOPS (CoresSIMDs(mul-add2+mul1)*clock speed)

Frecuencia de shaders o GPU * Cantidad de cores * 2 / 1.000.000= GFLOPS totales que da tu tarjeta.


I am wondering whether the GFLOPS calculation is based on 32 bit or 64 bit? What is SIMD? Can I found SMID and numbers of ad and mul in the datasheet? Is there any way around to calculate FLOPS? Please let me know if you have any information/document in this regard.
