ATI Radeon 4870 x2, rival NVIDIA is potentially looking at more problems with defective GPUs rolling out of its fabs. According to an article from UK tech blog The Inquirer, a recent batch of bad notebook chips was only the first sign of a malady affecting a wide swath of the firm's graphics processors.
The site reports that four of NVIDIA's partners are seeing G92 and G94 chips "going bad in the field at high rates." These two GPU parts power a number of the company's most popular notebook and add-in solutions, notably the 8800 mobile series, 8800GT, 8800GTS, 8800GS, and 9600GT. Laptops from Dell and HP are reported to be most affected, but with the problem seemingly creeping into stand-alone cards, desktops from these vendors – along with others, not to mention home-built rigs – could be in danger of GPU failure. Until there's a formal announcement from NVIDIA, new hardware purchasers should probably keep their receipts handy just to be safe.
