Ummm... lots of mis-info and assumptions being made in this thread.

#1- Charlie is NOT the source. A different source leaked some info and a very good informant even posted up the numbers Charlie was going to quote yesterday. This informant quoted similar troubles but slightly higher yields, still under 10%.

#2- G300 never was getting 20-25% yields, that was a compeltely made up rumor based on RV740 yields.
G300 was either just taped out or not even tapedout 3 months ago...

#3- G300 is supposedly around G200 size, even though it is on 40nm vs 65nm.
