Source : FudzillaFor NVidia, 2008 will have to be tagged as the darkest year. After the manufacturing defect affecting 8x00M GPU, the company is now facing another problem. Due to patent infringement, NVidia will have to disable in all its nForce chipset the "PCI prefetch function" for which the company does not hold the license. This feature speed up PCI performance, and without it, all nForce 500-series and onwards-based motherboard will be affected.
This mess will only affect PCI-based motherboard, and the current PCI-Express-based MacBook models should not be affected. However, NVidia would have much prefer not to have its name mentioned once more in the news associated with another problem.
