How to read result of bandWidthTest

Hi all,

I've run the bandWidthTest project for several times, each time I got different result. I would like to check my global memory bandwidth. Could you please guide me to read the result. Quadro FX 5600 is the one I am using, it lists 76.8 GB/sec as the memory bandwidth. Is this the global memory bandwidth?

The following is the result I got:
