writes the yields of AMD's Llano APUs are somewhere between 50 and 60 percent:
AMD did what you may call a tick - tick strategy, as they changed the architecture and the manufacturing process, which is definitely a tricky thing to do. In addition, let's not forget that this APU has a gigantic GPU attached on the same die to AMD's 32nm CPU. This is one of the most complex chip that was ever made in computer industry and it is really a big one.
Good yields mean that company makes more money but we are hearing Llano chips in a wafer work in 50 to 60 percent cases. Furthermore, the chip is quite big and you cannot get too many of them from one 32nm wafer. Good yields would probably be if 80 to 90 percent of the chips worked, while 90+ yeild is a really good one.
