You might try this formula:
Theoretical Max Value = Processor speed (GHz) * (4 FLoating-points OPerations per Second) * (Number of physical cores)
Theoretical Max Value = 2800000000 (2.80GHz) * 4 * 10 = 112000000000 FLOPS = 112.00 GFLOPS
How did you get the value of FLOPs? is it documented anywhere?
The 4 Floating Point Operations /sec
That was just an example. Use your processor speed, and number of cores.
