NVIDIA GeForce RTX 5090 PCB Pictured, Massive GPU Die and 16-Chip Memory Configuration
NVIDIA's GeForce RTX 5090 graphics card printed circuit board has allegedly been shown in the flesh, showing the memory layout and some interesting engineering choices. The custom PCB variant (non-Founders Edition) houses more than 40 capacitors, which is perhaps not standard on the FE reference board, and 16 GDDR7 memory modules. The leaked PCB, which extends beyond standard dimensions and traditional display connector configurations, is reportedly based on NVIDIA's PG145 reference design. While lacking the characteristic NVIDIA branding of a Founders Edition card, a little marking indicates that this is a PNY custom design. The memory modules are distributed systematically: five on the left, two below, five on the right, and four above the GPU die. The interface is PCIe 5.0 x16.
As NVIDIA has reportedly designated 32 GB GDDR7 memory capacity for these cards, this roughly translates into 16 x 2 GB GDDR7 memory modules. At the heart of the card lies what sources claim to be the GB202 GPU, measuring 24×31 mm within a 63×56 mm package. Regarding power delivery, PNY seemingly adopted NVIDIA's practices of using a 16-pin 12V-6x2 power connector. The entire PCB features only a single power connector, so the 16-pin 12V-2x6, but with an updated PCIe 6.0 CEM specification, is the logical choice.

There is a fan at the end that moves air upwards for more efficient airflow.. the PCB is shortened to fit that goal. You don't need a paddle.
I do not have an issue with
- windows 11
- windows 10
- nvidia psu connector
- * fill out whatever you want *
Some people are unable to see. That topic is old enough, enough said about that power connector.--
Let's wait for the hole hardware assembly to see the constraints. Nope. They are not smarter. Work experience most likely. Education. And a job at Nvidia. Not sure if there are robots, humans, aliens or something else doing that job. Maybe Artificial intelligence? Or autorouting software for the printed circuit board design?
If that was true I would never see any flaw in any nvidia product since that company existed, right?
Smart is always up to definition. in my point of view - bad cars and bad car brand. I disagree. If you have bad manufacturing quality. I did not want to write my story again. But I have to in context of those other quotes i did in this post.
You can not judge those connectors with the naked eye. You need a special measuring machine. That I learnt in my work experience so far in different companies. (more than one)
My corsair rm 750 psu died. I replaced it with a enermax revolution d.f 750 Power supply unit. I just checked the emails and conversation I had with enermax Thu, 2 Mar 2023.
on the power supply side some connectors went loose itself while doing the cable management. I wrote an email to enermax and got those cables replaced. These cables had no retention force. You can not see those injection molding defects with the naked eye. You need a ogp machine. I was lucky that on the power supply side the cables for the 24 pin connectors and the cpu connectors both at the same time did disconnect completly in my fractal design meshify 2 case.
I'm not allowed to talk about my previous employer. We tested those assembled connectors even the pull out forces
Visually you can not see those differences with the naked eye. when you have the replacement calbes and the bad cables with the power supply - you can mechanically test the retention force quite easily by hand.
you get bad quality when you have a "bad process" wiht your injection molding machine and the mold.
i recommend you "gently" pull with a little force on those connectors to check if they fit.
I'm more upstet about corsair and their shitty quality. I have no problem with enermax. cables and connectors are replaceable. but a dead corsair power supply which was never used over 50% of those 750W in 1.5 years is unacceptable. While having a full time job. It'S about the retention force of the connector. I do not have that spec for that connector. I can tell you other connectors have that specifications. And that is also tested for certain customers and certain connectors.
you can not see with the naked eye visually the differences from a "bad" and a known "good" connector. You need machines to reliable test that.
you need a decent factory with a good injection molding process. And another factory with a good assembly process.

I do not think it'S a valid argument to say people will complain and will not buy it.
If the build quality can be seen beforehand it's worse I won'T buy it. I look at the information before I buy something.
This post was edited by a mod, if you have to be so passive aggressive towards me,maybe just put me on ignore instead.
I actually ran my 4090 for 8 months with the clip broken on accident no flames......
If you know your way around, it's not an issue whatsoever for inference, and you can work around this for training by using fp16 acc for your passes. I'd still consider it pretty much a titan substitute for all ends and means, even in pricing, given how expensive the 5090 is supposed to be.
How about the first lot of 7900xtx cards that blew up because AMD screwed up the cooling on them. Do you post about that non-stop?
512-bit bus is something enthusiast crowd has been asking for ever since the last card that did that and that both was a long time ago and GPUs have become more bandwidth hungry.
32GB comes with 512-bit bus, is more than previous gen, there is current fascination with more VRAM and this segment gets a lot anyway so that is simply logical.
Is it expensive? Sure. But this will be ultra-hind end segment where cost is not the question but getting all that is technically possible is.
No, it is not overkill or stupidity.
Not a huge fan of looping DP from the graphics card to the motherboard either, not that I have a motherboard with USB4 support...
