NVIDIA GeForce RTX 3080 Pictured?

Here are what could be the very first pictures of a reference NVIDIA GeForce RTX 3080 "Ampere" graphics card revealing an unusual board design, which is the biggest departure in NVIDIA's design schemes since the original GeForce TITAN. It features a dual-fan aluminium fin-stack cooler, except that one of its fans is located on the obverse side, and the other on the reverse side of the card. The PCB of the card appears to extend only two-thirds the length of the card, ending in an inward cutout, beyond which there's only an extension of the cooling solution. The cooler shroud, rather than being a solid covering of the heatsink, is made of aluminium heatsink ridges. All in all, a very unusual design, which NVIDIA could implement on its top-tier SKUs, such as the RTX 3080, RTX 3080 Ti, and in a cosmetic form on lower SKUs. We get the feeling that "Cyberpunk 2077" has influenced this design.

If that is indeed the reference design expect these cards to be expensive.

Anyone who knows Sumerian here ?



Except both fans look like they are pushing air into the heatsink, the problem with such a design is that the heatsink wouldn't have enough surface area and the fans would have to run at pretty absurd speeds, >2000 rpm. It would be the least efficient design that I can think of.



It just doesn't work though. With radial fans the air has to be directed, so if you want both fans to blow in the same direction that means one of them would be blocked by whatever directs the air for the other one. In this case it would be just as bad, some of the air would go out the back of the card, except it goes through almost no fins so it cools down nothing and the other one would do the same. The heatsink itself would just get airflow from both sides and little place for the air to escape. No matter how you spin (pun intended) none of this makes sense.

Also in case no one noticed there is almost no place for the die to be on board. You can't have the fan directly over the die as that would limit the area of the coldplate and heatpipes too much.
So, conclusion, in your eyes? I mean, yes, I get your response to me and others, but you offer no alternative plausible idea for it :)

I won't say this is the best design mankind has ever dreamt up... but its a design and apparently it somehow makes sense.

I don't know who copies from whom.

Intel:

nVidia:


Tiny, teenieweenie difference, this is an actual sample, and those renders are... renders. So Nvidia beat them at their own game even if they somehow copied something ;) Says alot about the state of Xe more than anything. I think Nv has proven it can bring new designs to cooling. Their NVTTM coolers have always been 'oh, that actually looks pretty good' moments. Not that they cool like that, but that's another story :)

In terms of design style I'm getting a strong Knight Rider / Tron vibe from this, both in their own way.

There is a ton of aluminum on this card. I have not seen more on a card before.

Alternative in what ? I just said it's a poor design.

Hehe yeah... that does tend to turn into metallic painted plastic at some point down the line, is my experience :)

Nvidia's 2000-series RTX coolers were not particularly good, despite being very expensive to build, and the same overbuilt, poorly-designed FE cooler was on the 2060FE which was the cheapest 2060 on the market for the first few months after launch.

No one could ever accuse Nvidia of being value for money.:)

That "poorly designed" cooler kept the 250W RTX 2080S cool and quiet though, didn't it?
And the 2060FE was actually as good as AIB cards.
All this while being a 2-slot card and looking so much better than anything else on the market.

I would not be surprised if AMD, copies this design on their next gen RDNA3 once again...
Id rather AMD do more AIO stuff like with the Fury X.

I changed my mind. As someone pointed out, this cooler has probably a vapor chamber. If so, how can it possibly exhaust air in the underside of the card? (see pic in quote) Unlike heatpipe heatsinks, vapor chamber heatsinks doesn't let air straight through. Like someone else said, we can't see anything between those fins on the underside anyway, which is highly unlikely if that indeed was an exhaust. Maybe it's just fins on the underside of the vapor chamber, which makes this part (front, underside in case) passively cooled. (Yeah it can be a combination of VC and heatpipes, but still, we can't see anything in there anyway.)
Here's the vapor chamber of the 2080 TI FE. Pretty much no air, or light, comes through.

Totally irrelevant as the PCB design is not the same.
Sorry you can't wrap your mind around this concept.

Isn't it amazing how many desktop engineers are calling this problematic/poor design just from a picture? Again, if this is real, you have to believe it was tested and works from flagship down.

Nvidia's reference cooler on turing was actually pretty good. Better, by far, then their own blower reference cards and AMD's. I have faith this will do the job...will have some headroom for overclocking...

I can see the two fans wont fight over for the same air which is a big plus on its own. But in the end, reviews will determine how effective it is and how is the pcb sorted.

Wait, have AMD copied an Nvidia reference design? When?

looks like this is gonna be fun to clean
Nothing is too crazy since the Model O mouse got copied into oblivion. Cleaning is an experience in 2020, make no mistake. There is apparently a market :)

there's hardly any dust in my case anyway since I got the p600s

Got this pic off the sff.network forums where someone attributed it to "Someone on Techpowerup", sorry that I don't know who (can't find it in this thread, though I might be going blind). Anyhow, the originally sketched flow path (green and red lines) is problematic, so I added my own to illustrate. Even if the lack of a shroud makes for a thicker than usual fin stack, that fin area is tiny compared to most open-air coolers. Also, the lack of a shroud means nothing directing flow, meaning the air passing through those two \ / fin stacks in the middle of the card will be negligible - the majority of it will take the path of least resistance and get out of the fin stack ASAP (blue lines) rather than following the fins all the way out. As such the red arrows there are highly unrealistic. Also, a relatively large part of those middle fin stacks will receive pretty much no air at all (orange fields) - their only access to air from the fans would be a tiny channel in the middle, underneath the silver bar. Overall, for this to be even remotely effective there needs to be heat pipes running from that part of the cooler and into the other. If that is indeed the case, this could be good, though it would lead to a lot of recirculation unless there are other fans around to ensure a steady supply of fresh air.

Vapor chambers work the same, they don't let air pass straight through like heatpipe heatsinks, no matter the PCB design.

I think the idea of the rear fan is to assist the cooling of densely stacked SLI cards but I am not sure.

I like how they made it such that the fan can be seen through the fins even though in the pictures that isn't the case at all :).
Interesting point of view!

I think you misunderstand me. The FE coolers were adequate and kept the cards quiet enough and cool enough - I had no complaints with mine other than a driver issue (well, decision by Nvidia really) that enforced a minimum fan speed of about 60% of typical full load speed which was far too much and made the card clearly audible at all times. 1200RPM idle is ridiculous for a 160W card that never even reached 2000rpm for me during an OCCT burn test. Other FE cards have an even more ridiculous 1500rpm idle which is borderline obnoxious if you don't have game sounds to cover up the GPU noise.

Watch some teardowns of the FE coolers (gamersnexus were particularly vocal about the FE cooler, though by no means the only ones moaning about them) if you want to see what I mean about poorly-designed. They are clearly very expensive to produce with a lot of manual labour required in addition to the over-complex design. They're sort of 'bodged' together with far too many component parts that show all the hallmarks of a company that is inexperienced in making an open cooler.

Third party cards were usually cooler and quieter, all whilst having cheaper-to-produce, simpler cooler designs on them and using lower-binned, hotter-running silicon. I'm not going to deny that the FE cards were the best-looking on the market though. I think that's one of the reasons I bought one ;)
