AMD's upcoming Cayman has been the source of much controversy in recent weeks due to a number of rumours and issues plaguing the launch.
Most partners did not get significant quantities in time and they expected the launch to be postponed by a week at best. AMD also did not deliver the final BIOS version as planned. In addition, rumours of yield issues also emerged and now there is another report painting a somewhat different light on the issues.
VR-Zone is reporting that the card was not delayed because of yield issues, but rather because of a shortage of DrMOS chips produced by Texas Instruments. AMD started using the chips on the HD 6800 series and they are in tight supply. However, it's worth noting that the shortage has not affected 6800 cards for some reason and let's hope it stays that way.
Interestingly, VR-Zone is now reporting that partners still don't know the new launch date and that the date should be set by the end of the week.
