We will have to wait more to know something more.
Simple mathematics

several fillrate tests from 4850 in the wild show ~19500MT/s and clock of the Card (TMUs) is 625Mhz

with 32TMUs and 625mhz you get a theoretical fillrate of 20.000MT/s
with 40TMUs at 625mhz you get 25.000MT/s.

i dont think RV770 is that inefficent.
