Figuring out which NVIDIA GPUs are defective — it’s a lot

So now that HP’s joined Dell in releasing information on which laptops have those defective NVIDIA GPUs, we can sort of piece together which chips are faulty — and just as had been rumored, it looks like basically every Geforce 8600M and 8400M chip is affected. That’s not good news for NVIDIA, which has been saying that only “previous-generation” chips were problematic — unless the chipmaker is planning on updating the hugely popular 8×00 series sometime, say, now, that’s not exactly true, now is it? Other affected chips appear to be in the GeForce Go 7000 and 6000 lines, as well as the Quadro NVS 135M and the Quadro FX 360M, but that’s just looking at model numbers, and we can’t be exactly sure. We’d say that if you’ve got a machine with any one of these GPUs, it might be wise to call in and see what your laptop maker is going to do — and it would be smart for NVIDIA to come right out and say exactly how big and how bad this problem really is.

All NVIDIA 8400M / 8600M chips faulty?

NVIDIA’s stock took a pretty big hit last week when it announced that “significant quantities” of “previous-generation” GPUs and mobile and communications processors were defective and that it would take a $250M charge against earnings to repair and replace the affected chips, but the company didn’t say which chips specifically were faulty, nor how many. That might be because the problem is much worse than it even sounds — according to a report in The Inquirer, every single G84 and G86 GPU in the 8400M and 8600M series of cards is affected. Apparently both chips share an ASIC, and the core design suffers from the same heat-related issues. That certainly implicates a “significant quantity” of chips, all right, but this is just a rumor for now — one that’s probably best handled by NVIDIA stepping up and letting its customers know exactly how big the problem is.
