reported on Friday, AMD's upcoming Cayman appears destined for a delay or a paper launch, as some partners have still not received the boards, or final bios versions.
According to TechEye, the delay was caused by poor yields, which is supposedly in the single digit range. This is somewhat surprising, as the 40nm process is rather mature. Nonetheless, building a 3 billion transistor chip was never going to be easy, a fact clearly demonstrated Nvidia's GF100.
Taiwanese sources told TechEye that there was only a slight chance of AMD keeping its schedule and shipment targets in Q4. Cayman was originally scheduled for a November 22 launch, just in time for the holiday season. We can only hope that AMD and TSMC will manage to work out the kinks plaguing the new GPU in time to start volume shipments in early December.
