Well, damn:

Seems like I'm missing a few as well. Are we sure it's not a bug? I mean my scores in 3dmark seem to be in line, now it's OCed so its even better. Maybe the spec in the database is wrong?


Oh well that would explain it.

I went and checked the reviews on the 5080's, at the tables they're listed as having 112 ROPs. Seems the GPU DB is wrong after all.

Read above in thread, apparently its an error on TPU site, not bug with GPUz. 112 is the correct number.

The 5090 already uses a slightly disabled version of GB202, so I’m having a hard time imagining defect rates are so high to kill another 8 ROPs.

You need to understand that the larger the chip is the yields go down dramatically, it's why AMD is trying to use chiplets for everything, any section that you can fuse off is an improvement.

I'm just checking on my 5080 and apparently I'm missing almost 13% ROPs...

This was a mistake in GPU DB, the correct number is 112. I've updated our database

The 5090 already uses a slightly disabled version of GB202, so I’m having a hard time imagining defect rates are so high to kill another 8 ROPs. And even if they are, the 5080 uses a fully enabled GB203 so if they do want to launch a 5080TI Super or something eventually they’ll have to bin the 5090 anyway. They could start saving those dies now.

We're still looking at a 750mm2 die at very high density and >90M possible failure points. Anything above 550-600mm2 is really quite prone to yield effects.

Now... we've seen AMD chase the chiplet route... and they're now NOT producing a very large die RDNA4 card. Do the math. I think we might see those chiplets come back in the near future. Its the ONLY way to avoid these problems, when you've concluded the only way to move up is by scaling things up.

I tried to submit my vbios to online database, but it says BIOS reading not supported on this device.

I just released a new build of GPU-Z that supports BIOS reading on Blackwell

What's the opposite of Titanium? Something that's not cutting edge tech, that's brittle and cheap?

Yeah, I upgrade GPUZ to 2.63.0 and successfully upload my vbios to the online database.

And people thought that Radeon RX 9070 launch was a disaster. Including me. I was wrong. Terribly wrong.

I was wondering what do they do with all those defective RTX 4090 and 5090 chips that are actually functional but only partially.
Since it's insanely huge monolithic die, defect rate is muc higher than with chiplet approach. Yield must be way worse than with RTX 5080 dies.

Before this I read that RTX 5070 and 5060 are delayed because of performance issues:

NVIDIA GeForce RTX 5070 and RTX 5060 mass production faces delays - VideoCardz.com

NVIDIA RTX 5070 and 5060 mass production delay rumors Media reports from CTEE suggest that NVIDIA encountered a performance issue in its mid-range GPUs, forcing a delay. As we know, NVIDIA has already confirmed that the GeForce RTX 5070 non-Ti has been delayed until March 5. The company...

No other AIB cards reported to be impacted by the same issue yet? I'd expect PNY and Manli to be in Zotac's club as well.

I’m aware of area scaling and the fact that this gpu is quite a bit larger than even the 4090, but TSMC 4N is a pretty mature process. Like I said they could’ve turned these into a 5080Ti later, or even some slightly different professional grade GPU that consumers don’t usually see. For NVIDIA to be willing to scrape the bottom of the barrel and impact the reputation of their halo product for just 8 more ROPs feels like either yields are worse than they expected (otherwise why not just release vanilla 5090 with 168 from the start) or something else is going on. Maybe they did almost release the 5090 with 168 ROPs and some snuck into the release channel, but that seems like a major screwup too.
Basically what I’m saying is that anything that could make them need to disable 8 ROPs should’ve been known about well before the 5090 came out anyway. Super weird situation here.

I sometimes wonder if anyone's ever put a AD103 and a GB203 under a microscope yet.

You know...Just to make sure?

I was honestly thinking about that the other day...so when you see something like this it kinda verifies something like that *could* happen. It never made sense AD103 has 2/3 of a shader cluster.

 

[Vya Domus]

Who knows, maybe board partners are pissed because the supply is so low and they wasted all that money on marketing and promotion and so Nvidia came up with a solution to slightly boost the supply of chips.

 

[alwayssts]

I've been waiting for somebody to say it, and they haven't, so I will bc well...gotta have some fun w/ this stuff:

When nVIDIA does it, it's a bug. When AMD does it, it's a feature!

Hm, wasn’t there recently a rumor that due to lower than expected b200 demand some wafers were going to be pushed to GB202 production instead? Wouldn’t it be funny if actual rush in 5090 supply came from simply using broken chips and lying about it.

 

[FiRe]

So, fraud

 

[InVasMani]

Pepperidge Farm Remembers when you would unlocked more ROPs on NVIDIA GPU's...

 

[Wuxi-gamer]

It's such a relief to know that I'm not the only one who has this problem. Thank you very much for checking it out. Now waiting for a response from Zotac/Nvidia.

 

[Cheeseball]

Damn. More ZOTAC drama again. LOL

First was the shitty customer support throughout 2014 to 2020, then blatant price gouging and mining-promotions during COVID. Now its cut-down GPUs which may not directly be ZOTAC's fault since they don't fab them themselves, but they are involved since its only been seen on their boards.

 

[Darmok N Jalad]

LOL, on eBay, these Zotac 5090s are listed for over $4000.

 

[R0H1T]

Just 5k short of a meme then

Spoiler

 

[dyonoctis]

Calculated risk. These chips are expensive. What's 8 rops, hopefully customer won't notice, profit.

Its the same lame low-effort production method as what we've seen on 12VHPWR. Bare minimum, and actually, not even that. On halo products. You can't even make it up. What used to be hidden behind just the unified product lines, is now showing its true nature because these cards have crossed every line of common sense. High wattages to cover up zero progression; a new gen that offers literally nothing new, etc. A 5090 is nothing other than a cheap ass x60 except with more cores and chips around it. Everything Geforce is now in the low-effort budget segment for Nvidia.

Enjoy that thought while you pay >2000 for your graphics card.

Back in the days, it would have been called a RTX 5090 SE. Or RTX 5090 168.

In times of GTX, it would be a GTS. So maybe RTS 5090?

 

[HD64G]

5090D for China, remained and sold as a full 5090. What a mess this gen has become with burnt connectors, fake MSRPs and untra-low stock and now this...

 

[AusWolf]

I'll call it the 5090 GTX 970 Edition. The way you're meant to be played.

Collector's item by now.
