NVIDIA RTX 5090 "Blackwell" Founders Edition to Implement the "RTX 4090 Ti" Cinderblock Design

[btarunr]

NVIDIA's upcoming GeForce RTX 5090 Founders Edition graphics card may implement a design closely resembling the cinder block product design the company readied for its RTX 4090 Ti graphics card that never materialized into a marketable product. This sees a 4-slot thick board design, with a slender main logic PCB arranged along the plane of the motherboard, on top of which the cooling solution is mounted perpendicular to the plane, as shown in the images below. This main logic board contains the GPU, memory, and VRM. There two additional PCBs—one has the display I/O, and the other has the PCIe interface. There is a fourth disaggregated component, the 12V-2x6 receptacle, located somewhere along the top of the cooling solution.

Confirmation of NVIDIA using the RTX 4090 Ti "cinder block" board design for the RTX 5090 comes from kopite7kimi, a reliable source with NVIDIA leaks. Kopite7kimi mentions a card that has a "Main Board, IO Rigid Board and a separate PCIE slot component (perhaps it should not be considered as the third PCB)," which perfectly describes with the RTX 4090 Ti. NVIDIA had completed the design phase of this card, which made it to its cooling solution OEM (which is likely where the images leaked out from). The company probably decided against launching this product because the AMD Radeon RX 7900 XTX fell significantly short of the performance proposition of the RTX 4090.

Does Nvidia still provide the 12pin power connector that can catch on fire? That's always a nice addition to a $2K+ card.

Just launch GPUs with a waterblock already.

Prometheus can only be assuaged with fins and air for so long.

Just looking at the 3rd & 4th pictures gave me a backache.

LOL @ those people with those tiny little SFF builds.

I need bigger cooler so I can fit an entire PC onto my GPU

If that's the cooler it needs there is no way this thing is costing less than 2k.... Return of the Titan

Maybe rumors of a 512bit bus monstrosity are true.

It comes with wheels and a Jetson add-on so you can (self) drive it to work.

 

[chstamos]

They should pack GPU holders with this crap.

 

[Chaitanya]

Why waste the money that was already spent on engineering that cooling assembly.

 

[Evildead666]

From what i can see, i count 11 heatpipes.
Holy crap !

With full level 5 FSD or the imitation cheapskate Elon is selling you?

It's not a "Blackwell", it's just a "Brickwall".

No idea what chassis would handle that monster and what kind of lever you will have to use to keep it unbent.

This looks like its going to be very expensive. But cheap if you can afford it!

Not a bad idea

Clearly matches Jensen's logic:

4 elephants = 1 GPU

A pass-through design with some X-shaped trim? Where have I seen this before? Oh yes! On every other Nvidia card in the last 5 years.

So where's the "leak"?

There havn't been any fires, and no more further melting reports since people stopped using CableMod Adapters.

 

[AusWolf]

Who wouldn't want an engineering sample like this?

The video is a bit old by now, but still a classic.

Well it's a nice addon.
For 2k+ you'll get a beast of a gpu and a free campfire.
Why'd you not want that.

HAF 700 EVO maybe or Enthoo Pro 2 Server

4 Slot design oh boy. Motherboard makers might want to redesign their boards. Case makers might want to do the same thing or maybe something new that would fit it somewhere?
Come to think of it. It also points to what the power consumption might be more or less. It wont be little that's for sure.

dont u dare to jinx that new toys from jensen huang, dude..... ^^

any way..... its very scary, that rtx 5090 series could be so BIG like that..... its freaking me out..... but, i hope rtx 5080 series will be more slim, also not as hungry power than rtx 5090.

Am i the only one that is perplexed how the PCB will look like? from the first photo, it seems that the pcb will be on the bottom of the card, not the classic side/behind the cooler. maybe a left angled PCIE connector? Looking at the fourth and fifth photo i see 2 big copper conductors, maybe to bring the 12v from the 12 pin connector at the top of the card to the PCB?

Purple - power rails
Orange - 4 hdmi/displayport
Green - Pcb
Red - 90° angled PCIE connector?

 

[P4-630]

No thanks...

 

[atila pereira]

Triple fan ?

The article mentions 3 separate PCBs - main PCB parallel with motherboard (goodbye to using any other slots!), output PCB with HDMI & DP sockets, Input PCB with PCIe slot. 12V Hpwr socket elsewhere on the heatsink.
