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.

Quite low quality design. The thermal density will be high - 600 watts in so small area will be tough to keep cool.

1. The PCB will melt;
2. The single power connector will melt;
3. Wrong PCB size;
4. Too many memory chips - this needs either 3 GB or 4 GB chips.

Overall, given the $3000-4000 price tag - it is a meh. Don't buy.

That's a big one!!! 512bit and 20+3 power stages. Yup that pcb is too small. The weight of the cooler will crack the PCB real fast on AIB cards.
If the 4090 just melted the connector this one will go supernova.
Do NV also supply a fire extinguisher in the box?

Of course not. It's a user's error if things go wrong.

Well it's official, Jensen's overcompensating. Poor guy.

It's gorgeous... Looks very well designed, anyone can tell that but salty fans of admittedly mediocre devices :).

So the 5090 it's an 512-bit card, while the 5080 it's a 256-bit card.
Good job nGreedia! /s

I must be doing something wrong cause my connector is still fine. It's been 2 years...

With GTX 200 series they did it right, 280/285 had 512bit and 260/275 had 448bit.

Or like with 1080 Ti and 2080 Ti, just knock one memory chip away and have the membus at 352bit.

If true this card will be instant 100°C
I don't know they squeeze so much the pcb ?
what for ? money ? again....

Vrm need to be away from mem chips/gpu core and same for memory
At least 2x16 pins 3 fans and a 2Kilos cooler

Good luck for repair when it's dead by crack or bend board
Will see

Same. I plugged in my card years ago, and it's fine. Same with my CPU...

No issues here , since day one .

Kingpin was associated with EVGA, but following their exit from the GPU market, he has moved on to work with PNY

Can we please get the USB-C port back?
One cable monitor connection for both display signal and USB data should be a thing on desktops too, not just laptops.

I guess that's what happens when you can't keep shrinking nodes gen on gen, you WILL have to get creative if you want to extract even more performance, and it seems like they reeeeeally wanted to extract more performance.
Or maybe this is just an enterprise card and we are being fooled, who knows!

PNY doesn't make enterprise cards.

Makes total sense, its also got double shaders and VRAM right?

Indeed. Double the shaders, double the VRAM, double the price, double the fun, 30% more performance.
Makes total sense.

That was 448 bit and 352-bit. NOT 256-bit :laugh: :laugh: :laugh:

Yeah.. I don't think video games are what this beast is made for.. the fact that it can play them is just a byproduct lol.

For people who are going to do work on these 3000-4000 is cheap. This is what keeps flying over peoples heads here. The x090 series are the new Titans. The gobs of memory, price, features, and more directly reflect that. That they also happen to be gaming monsters is an after thought and a bonus for people that have the spare cash but that is not the point. Go look at some of the companies that had the specs and their waterblocks in place prior to when gamers knew what they were going to be. They ship them in four or 8 per box with high end threadripper and xeon based systems. That's the target.

If you are a gamer looking at these you're doing it all wrong. I've owned most of the Titans and x090 cards and I don't game on them. When I give them away to upgrade the people who get them are not gaming on them either.

The prosumer market is highly blurry where the cards are cheap for professionals but good enough and way over what a consumer can use. But make no mistake since the 8800gtx nvidia has been open they aren't a graphics company for gamers and that's not what they care about.

Gotta give it to then, all those years giving us products saying "hey, buy this toy and play some games on it, but also take a look at what else you can do with it" to get us hooked up in their ecosystem during our professional lifetime, just like drug dealers lol

Sooooo to summarize (without all the techno-babble/marketing hype):

Big chip...
Big socket.....
Big PCB.......

And last but not least.....

wait for it...

wait for it....

A GIGANTIC, HUMONGOUS, bank account-BUSTING PRICE !

Looks like Jacket Man will be getting LOTS of new jackets next year, hehehehe
