Can't agree more. I can only get it where I'm for 6500+ USD (Not from scalpers). Stupid.

The price. Scalpers. Availability. The power cable. What's left?

Whoever had QA duty the day this batch of defective chips were approved for release to the AIBs is probably already looking for a job.

Oh you must be new to this if you think AMD hasn’t had dumpster fire paper launches in the past with sub par over promised hardware and misleading graphs.

You are saying AMD had a card with a certain spec on paper but the actual card had missing or disabled hardware.
The 5090 SPEC says it should have 176 ROPS and this one only has 168. Disabled or missing hardware.
Show me where AMD had ROP = XXX but the actual hardware was YYY. Or any version of that.
This doesn't have anything to do with promised performance but usable hardware.
 
I would have imagined AIBs usually test them in some way before using them and after assembling the gpu, maybe they only go by temp-performance result and they went over the bar without looking at working core counts

Nvidia pulling a AMD

They both have had trash launches lately.

Nvidia has zero reason to improve because people are happy to pay for the pleasure of being bent over and take it dry.

AMD for some reason has people in their GPU division that either can't or don't want to look at how successful their CPU revitalization has been regarding marketing and value.

It's more important than ever that Intel gets their GPU's off the ground to really begin competing in the mid to upper-middle tier. Hopefully at least the most of us normal users that don't need a 5090 can hope that drives better competition.
 
So, lets be honest......This is basically a 5080ti card they released by accident...

Makes ya wonder if they are hoarding those chips and accidently put them in a batch of 5090s..

Funny times indeed.
 
Next it will come out that their cards really only have 28.5gb of ram.

I wonder if Nvidia was mad at Zotac or just figured buyers of Zotac cards would be less likely to notice.

They test them to ensure they function, don’t crash, etc the basics, yeah there a quick stress test but they aren’t checking scores just functionality.

This is a QA issue above the AIBs, Nvidia sells them the silicon they use in their cards and it’s Nvidia’s job to ensure the parts are labeled correctly and running to spec, and that is something they contract to TSMC who checks them after packaging.

So this would indicate a failure at the top, unless it wasn’t a failure….

Here me out, the 4090 was a slightly defective chip and the full chip went to the workstation cards…
What if the 5090 was originally going to be the same and in the rush Nvidia changed up the plan but never pulled the old stock.

It looks to be affecting 4-5 vendors. MSI, Gigabyte etc etc.

Ya that is much worse. I mean its a minor fusing, but this is what GRE models are for... oh wrong company. More bad 5000 PR.
I feel for people that may have paid insane scalper pricing for some of these.

Jensen cancelling the 5000 series and announcing that NVidia is leavng the consumer GPU market, effective yesterday. All driver work halted and the driver teams "DOGEd" from their jobs.

4090-5090 are both 88-89% enabled chip not full chip.

They seem to run quite extensive test in some ways (and temp), to see if the boost clock reach the specs (they will usually bin them, put the best clocking one in their super OC edition), RMA is costly, a run of 3dmark an an alarm under score X would not surprise me:
MSI for example:

You can see them run 3d scene, they test them before mounting them to a pcb and after, at 3:40 it once assembled, once in a bench setup, they also need to run a Nvidia-AMD as proprietary test suite and must return as positive for them to sell the cards as well, that throw error code on defect found.

I was referring to this being a dumper fire shitty paper launch, and misleading at best.

Semantics man. Bad launch, overpriced hardware. It is what it is.
 

NVIDIA’s GeForce RTX 5090 “GB202” Chip Turns Out To Be Defective For “Specific” Units In The Market; All Variants Potentially Affected By The Issue​

Well, when would gamers find peace in the GPU markets? Initially, we had inventory issues, with NVIDIA's flagship RTX Blackwell model being available in "marginal" quantities, and now, it is reported that Team Green's silicon has turned out defective for some of the models out there, creating a massive performance degradation. We recently reported about a ZOTAC GeForce RTX 5090 experiencing this issue, and now, according to @MEGAsizeGPU, the core issue actually lies in Blackwell's GB202 chip, which we'll discuss next.

I wish this wasn’t going to happen but really does anyone think they will be in stock at a reasonable price at all? Ever?

Don't worry, instead of swooping in to save the day AMD is going to flub their launch even worse. We live in clown world.

Maybe the gimped ROPS ones will get resold for cheaper... :ROFLMAO:

Just read that on wccftech. Amazing. Imagine some loyal nvidia lovers paid two thousand dollars for this garbage.
 
I can't help but assume Nvidia knew about the missing ROPs and shipped them hoping to not get caught. If supply wasn't so constricted they probably wouldn't have been.
