During the latest financial conference call AMD Interim CEO, Thomas Seifert, revealed that AMD was well on schedule to release the first 28nm GPUs in 2011 - "We have working silicon in-house and remain on-track to deliver the first members of what we expect will be another industry-leading GPU family to market later this year. We expect to be at the forefront of the GPU industrys transition to 28nm".
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 AMDs 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 AMDs A-Series, the Radeon HD 7000 could be a mix and match of architectures as well as fabricators.Source: Xbitlabs
