Maybe TSMC has had problems with 80nm - and this is why UMC is getting a look in. It's amazing that the analysts didn't press this point. Sorta: "Our mainstream parts are late, so our margins are hit by having to use enthusiast-level GPUs." "Oh, OK." Lame.
I wouldn´t call it problems, it´s more to do with TSMC´s plans to offer every customer a substitute for their 90nm process targets, meaning they need time to fully qualify not only their low-end, low-power and high-output targets, but they also need to cope with high-speed targets since TSMC is known for their customers to be very demanding especially in this field.
UMC is getting a look in because UMC always was ATI´s low-end FAB with substancial volume and very good yields and quality services. Based on that, UMC always wanted to grow even more, so they forced themselves to be competitive with TSMC not only process technology wise, but also on pricing and naturally this also leads to price biding between those foundries, since they need every FAB to be fully utilized to make money. Nothing is worse then having bought millions worth of equipment and leave it unused. UMC actually was in-front of TSMC, WRT their 80nm process, meaning they already shipped final silicon, while TSMC still has the advantage (and that takes additional time) that they offer more process targets.
Yields may be not quite as good as they´re on 90nm, which isn´t a secret, but i don´t buy that exaggerated "yields"-thing, not even for a second.
ATi is working with TSMC very closely and have been for years, meaning they both depend on each other heavily. If you take a look at ATI´s very early roadmaps, dating back to the beginning of this year, they always forecasted/planned those parts to be in full production in late august, early september, so there may be some delay involved, but since Orton didn´t exactly specifiy what caused this delay (and i´m pretty sure it´s because they still have X1800/X1900 inventory, which needs to be sold first -> the inventory "hangover" he also spoke of), it´s understandable, but not quite "definitive" that this has anything to do with the quality of 80nm in general. It´s nothing that should come as an unexpected surprise.
