It seems that GPU-Z 0.2.4 shows 800 shaders.. does not really correlate with a TDP of 110W but time will tell..
Also note your calculation of 160 shader * 625MHz = 1TFlop is really cool but suffers from a small detail: The shader clock is _unlocked_ in the 4850 series and does not operate at 625MHz, the GPU frequency. (The actual marketing calculation goes probably more in the line of 480 SP * 2 Ops * 850MHz = 0.8TFlop + TMU ops + GPU ops + Whatever ops >= 1 TFlop.
