NVIDIA on Wednesday denied rumors that the majority of its GeForce 8M mobile graphics chips are flawed. The video hardware maker contradicts the earlier reports that all G84 and G86 video chipsets are more likely to fail and tells Ars Technica that only a subset of its graphics processing units (GPUs) are at increased risk, with just a "very small percentage" of that group likely to die early. When that happens depends entirely on the specific notebook and is more likely to happen with systems running intensive tasks or in warm climates, the company says.
The chip designer has already taken the steps of developing a software driver that downclocks affected chips to prevent them from overheating, and has made sure that none of its in-production chips suffer the same flaw. Desktop parts have never been affected, the copmany says.
NVIDIA's assertions haven't been corroborated elsewhere but potentially assuage worries that all of the affected chipsets would die early. The G84 and G86 platforms are used throughout much of the company's GeForce 8M series and are used in many mid- to upper-range notebooks, including those from Apple, Dell, HP, and other major PC builders.
