FLOPS calculation: 750 x 2 x 800 = 1.200.000 for 4870; 625 x 2 x 800 = 1.000.000 for the 4850.
Sorry, but you are the one missing things. My point is, the mere existence of a shader clock in a separate domain would throw a wrench in the works of the calculation you just made, the number of SP's and also the slide itself being valid.

I'm telling you there is a separate clock domain

Figure the rest out for yourself.
