This is either a very weird driver glitch, or NVidia has a very serious problem.
This must be much lower level than the driver.
This comes down to the binning process, where the appropriate lower quality ROPs are "fused off", I can only come up with two possible reasons why;
1) The affected GPUs are a lower bin, which for some reason was combined into the same SKU, and these missing ROPs are "defective".
2) The affected GPUs have 8 fully working ROPs fused off unintentionally, which makes the GPU avoid using these. A Nvidia engineer would be able to explain exactly how this works on a hardware level, but it's one of two;
a) Somehow "burned" into the chip, so no firmware update can change it.
b) Controlled by firmware, but in this case they should have fixed it instead of taking returns. (and now with multiple models affected…)
Either way it's not a driver issue.
Is there anything I've missed?
Also,
every finalized graphics card is run through extensive validation by the AiB partners, it surprises me that none of those checks validates that the reported hardware matches the spec.
This is grounds for class action law suit right? How soon can we expect one? Nvidia needs to get their shit together.
That would have to be done per country (or EU combined), and after years of deliberation and a settlement is reached, owners will get their ~$2 after lawyer fees.
I'll get a 9070XT in pure retaliation.
And most will quickly return when they get burned there too…
I think it's obvious to everyone that "0.5%" is a blatant fabrication - but who can prove otherwise?
Firstly, they
do know the exact number, as this is a binning issue. But whether the reported figures are correct or not, I have my doubts, considering very few units are in use and users have a very low probability of detecting this, so my expectation would be that the real figure is in the ~10% range. (That's just a qualified guess, but don't quote me on that.)
It is however always hard for the public to gauge how widespread an issue may be, especially problems which may be tied to specific production batches, and a few people shouting loudly in the forums. A couple of generations ago Nvidia got a tremendous amount of flak for the "space invaders" defect on certain RTX 2080s, which in the end turned out to be an issue with EVGA. (Except for the random occurrences which is normal with mass produced graphics cards.) Outright failure rates with graphics cards are still very low compared to e.g. motherboards, and CPUs are even lower. So we have every reason to expect a graphics card to be fully working, and we should continue to hold vendors to that standard.
