24-pipes R520 Yield Rate at 3%

We heard that the last R520 spin at TSMC is at 3% yield rate for 24 pipes and we can certainly expect a much lower yield for 32-pipes R520. Obviously ATi is still facing some yield issues for their R520 @ 90nm process and ATI could resort to a 16 pipes R520 for better yield and make up the loss with a much higher core clock of 700MHz+ as INQ has previously suggested. It is still possible for ATi to keep to the time frame of August-September launch if decided to go ahead with 16-pipes R520. If not, 24-32 pipes R520 is expected to delay further to Q4 this year.

It seems like the so called 7800 Ultra card that takes up dual slot with 4 heat pipes cooler design...
