AMD senior vice president of platforms Rick Bergman said there are no plans to shift the company's entire GPU production to GlobalFoundries in the future. Despite lots of problems with TSMC's 40nm process, AMD continues to support the Taiwanese foundry, stating multiple sources are necessary to be successful.
Last month, AMD admitted that its short supply of ATI Radeon HD 4770 GPUs - RV740 - was due to TSMC's disappointing manufacturing yield on 40nm process technology. In June, the Taiwan fab's 40nm production yields stood at less than 25 per cent, a figure far lower than any chip designer would like, especially AMD.
The problem apparently was so bad that TSMC had to offer AMD preferential quotes in compensation. So, why, we asked Bergman, was AMD being so forgiving?
"New technology isn't easy," Bergman told the INQ, adding "you get rough spots on occasion, and TSMC has hit a rough spot."
