NVIDIA GeForce RTX 5090 Spotted with Missing ROPs, NVIDIA Confirms the Issue, Multiple Vendors Affected, RTX 5070 Ti, Too

[Vya Domus]

The kinds of defective RTX 5090s discussed in the article have 168 active ROPs, so they can be disabled in groups of 8 or factors of 8. I would think that disabling the same 16 ROPs via VBIOS would cause yields to plummet because those left could be damaged or failed.

I imagine they are sorted by which ROPs are fussed off and configured independently then sold as different models, sometimes even amongst the same model you have cards that come with different versions of VBIOS.

I also explained that there are just way too many defects to figure out by simply checking fuses.

that come with different versions of VBIOS.

The VBIOS does not configure any unit counts on modern GPUs, hasn't for like 10+ years. The VBIOS is identical on all cards, no matter how they are configured for harvesting.

Because otherwise people could unlock units and GPU vendors really don't want that. Yet its how this journey into computer hardware began for me around 2003

If they are physically disabled as I am assuming it must always be the case these days there would be no risk of that, even if it's by means of blowing fuses or whatnot. Every wafer gets checked for defects anyway, I just don't see why you'd leave it up to software, it's not reliable and in theory there would always be a risk of someone finding out a way to enable them.

Why does Nvidia talk about seeking replacements rather that giving people the option to update the VBIOS. This doesn't make sense, if they are defective this means there is no risk of unlocking units, if they aren't that means they were disabled through the firmware and this could be fixed by a VBIOS update but why would they ever do that in the first place, doesn't sound plausible at all.

 

[N/A]

to be honest 5090 should have had 240 ROPs for the shader count.
Now it's just a pale shadow of what it could be. 8 ROPs is not the only issue here and you're missing the forest for the trees.

Paper launch, fake prices, fake frames, fake resolution, terrible generational performance uplift, bricked cards, flawed board design, defective chips and no PhysX. But hey, at least we got real flames for our $2,000 $6,000 card.

except Macz is correct

No. The economic theory that user presents is little more than amateur-hour nonsense.

For people buying directly a dGPU through retail, you are probably right, but what about people buying prebuilt ?

That's a larger, more expensive purchase. Do you think people would not do their homework? Sure, some don't, there are always going to be those who buy based on buzz words and flashy gimmicks. But to say most are like that is very narrow thinking indeed.

What really sucks is that you are not wrong. This has become the most pathetic GPU launch in history. What makes it even more pathetic is that NVidia is likely going to call it a success.

das ist nicht gut

Translation, That is not good.

This is either a very weird driver glitch, or NVidia has a very serious problem.
