This is no surprise, of course, considering AMD have always been first to a new process technology, well ahead of NVIDIA. However, 40nm has been an exception, a trouble process lasting for well over 2 years thanks to the cancellation of 32nm and constant delays to 28nm. Some thought this would allow NVIDIA to catch up, but the latest rumours have suggested AMD releasing 28nm GPUs in 2011, with NVIDIA following up sometime in 2012. 

 

Seifert also confirms that 28nm GPUs will be fabricated at both TSMC and Globalfoundries. This would mean that certain GPUs will be handled by TSMC, while others more suited to Glofo will be assigned to them. 

 

Few details are known about AMD's next-gen 28nm GPUs, codenamed Southern Islands and rumoured to be branded Radeon HD 7000 series. With VLIW-4 still only used in HD 6900 series, GCN looming and VLIW-5 required to crossfire with AMD's A-Series, the Radeon HD 7000 could be a mix and match of architectures as well as fabricators.
