AMD's 40nm ATI Radeon HD 5000 series and 55nm ATI Radeon HD 4000 series GPUs are currently both facing shortages; the former due low yields on Taiwan Semiconductor Manufacturing Company's (TSMC's) 40nm process and the later due to AMD's conservative attitude towards its 55nm GPU sales after the launch of 40nm products, the sources noted.

AMD released a new generation of Radeon HD5000 series of graphics cards, in addition to the first to provide support for DX11, there is the biggest highlight Eyefinity technology, for the first time graphics output interface from the two-headed extended to three or even six, AMD claims that Eyefinity technology, the output image has gone beyond the human eye resolution limit, can be for gamers or professionals to provide the perfect display of the program.

If ATI plays it safe it will develop the chip for both TSMC and Globalfoundries and will benchmark which of the two gets the job done better. AMD is yet to announce that it will officially do its GPUs in Dresden bulk part of factory, but this is something that won’t surprise many people.

Never missing a beat, AMD's Huddy fired back in a little over 24 hours, further suggesting that NVIDIA is "moving its focus away from gaming", before concluding that "GPU leadership is presently AMD's".

TSMC said it has seen yield rates for its 40nm node drop to 40% due chamber matching issues. Main customers for TSMC's 40nm processes are GPU vendors AMD, which recently launched its new 40nm-based Radeon 5870 series, and Nvidia, who is scheduled to launch its 40nm-based GT300 series of chips in December, according to previous reports. TSMC's recent issues may impact the shipping schedules of the GPU vendors, market watchers commented.
