It's probably just a bad GPU. Unfortunately the 40nm process those chips are made on is full of problems. The ones that work properly are superior to all else on the market but a few slip through the cracks that are right on the borderline.
According to Digitimes, Taiwan Semiconductor (TSMC) can't get its manufacturing process to yield more than 70 per cent, which is causing huge problems for the production of next-generation graphics processors and FPGA (field-programmable gate array) chips.
TSMC is the foundary of choice for GPU vendors AMD and Nvidia as well as FPGA chip supplier Altera.
TSMC HAS FINALLY come to terms with its 40nm ordeal. In a transcript published by EETimes, Shang-Yi Chiang, TSMCâ€™s R&D boss, laid out six bullet points to explain the situation the company is coming from, what steps itâ€™s taking to make amends and where it's going.
The 40nm yield issues were blamed on the companyâ€™s previous lack of experience with the new, smaller node. Without going into too many specifics, Chiang explained the delay in achieving a viable yield was due to it using 193nm shrink immersion on the wafers, which resulted in a high defect rate, and also its low-K process that would damage the dies when converted into a package. TSMC is looking at extreme ultraviolet and e-beam direct write as alternatives to shrink immersion depending, of course, on cost.
Having its clients breathing down its neck couldnâ€™t have been easy. TSMC immediately started developing its 3rd generation manufacturing process on the node. Currently, output for 40nm wafers is 80,000 wafers per quarter, as only Fab 12 is manufacturing these. However, the company vowed it will be able to double that by yearâ€™s end, that is, 160,000 wafers per quarter, once Fab 14 is up and running.
Considering TSMCâ€™s major clients are the likes of AMD, Nvidia, Broadcom and Qualcomm. not to mention Intel, it seems that it's taking fairly important measures to reassure its clientele about its manufacturing. Of course we should expect a reaction from Global Foundries soon, as it are developing competing processes in their own house.
So, if youâ€™re a GPU buff, late 2010 or very early 2011 would be a good estimate for a new generation of GPUs. That, or smartphones. We'll have to wait and see. >Âµ
It all just depends on when you want to buy a video card. If you are wanting to buy something between now and spring of next year you might as well buy a 5750 and test it with your favorite programs before the return period is up.
I wouldn't hesitate to buy one but like any electronics product there will be duds.
If I got a dud I'd return it and get another one just like it. More of them work than don't.
Besides any other video card you buy is likely made with the chips from TSMC. It doesn't matter what you pick you can't avoid them right now.
