At this point, it's pretty clear that AMD's Radeon HD 5800-series graphics cards are in short supply—especially the 5850. What you may not know is that, according to DigiTimes, this scarceness has forced both PC makers and AMD to rejigger their roadmaps.
DigiTimes writes that tight supply "has caused several PC vendors to delay their mass shipment schedules by about two months to the first quarter of 2010." AMD, meanwhile, has reportedly postponed the release of Mobility Radeon HD 5000-series products, code-named Manhattan, from the fourth quarter of this year to the first quarter of 2010.
Radeon HD 5000 cards aren't the only affected products, either. DigiTimes claims Radeon HD 4000-series GPUs built on 55-nm process technology have also become harder to come by because of "AMD's conservative attitude towards its 55nm GPU sales after the launch of 40nm products."
TSMC, which makes the majority of AMD and Nvidia GPUs, recently admitted that its 40-nm yields had fallen to 40%. The foundry pledged to get yields back on track by the end of this quarter, though.
