RV670 cards will have smaller PCBs and less complex compared to R600 cards and as RV670 is a mainstream card it will have to cost less than the high end PCB.

Our sources indicates that RV670 card will have 8 to 10 layer printed circuit boards and this will keep the cost of the cards on the acceptable level.

The same sources also have confirmed that the new chip will have TDP way under 100W and this certainly means that the new chip will be significantly cooler than the current ATI’s high end.  One more time RV670 is mainstream but it should bring some performance close to the current high end.
