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.

Its an interesting take
Altho they could've gotten the idea of extending the heat-sink/fan-shroud over the PCB from someone else, say, Sapphire 5700xt Nitro+, Nvidia sure took it up a notch.
Another interesting thing is that the two white stripes we can see faintly from the rear of the card under the semi-seethrough plastic back.
My first guess is they are heat-interface materials usually stick on VRMs but what are they doing on the back of the board? There's no metal backplate to assist on spreading heat. Maybe it's just a habbit. Don't know they are doing it :p
So Nvidia concludes that instead of a blower reference design, it's going for a sucker reference design????? Ironic.
For those who do care about looks, rest assured there will be plenty of AiB variants.
I only wish at least one of the could go for more of a "tower cooler" design. I wouldn't mind the cooler being 6 slots as long as it pulled the air out in a silent fashion, and a such design would make much more sense in a typical computer case.
Here's the vapor chamber of the 2080 TI FE. Pretty much no air, or light, comes through.
This thread is 99 % speculations, and there are countless posts that suggests so.
The flow of air once it hits though depends on which direction the gaps dictate.
Saying they are designed that way is not correct, it is physically impossible for air to dissipate any other way with such a design.
rdna 1 is a new uArch with lots of changes and because the teams are small and the task is huge (nvidia is much larger than AMD), budget/timing constraints mean that navi 10 had a lot of hardware bugs that meant it is not efficient and required a lot of software tweaking (read drivers) to even make it work. You can see all these traits in the 5700xt. It eats a lot of power for a small-ish chip on 7nm, that even turing on 12nm is better. As regarding the drivers and the bugs...people are still complaining about crashes, so yeah. They were forced to sell it at a low price and create lots of subproducts from it in order to sell as many dies as possible, unfortunately for cheap. The strategy worked partially but many users got frustrated with bad drivers (in essence the drivers are OK, but you can do so much to hide hardware bugs) so they switched to nvidia. Anyway, this meant they couldn't launch a big die gpu based on rdna1 within reasonable power consumption/budget and thermal, so the focus was shifted on rdna 2 which is an improvement in many regards to rdna 1 but especially it has bug fixes for all the power/functionality related stuff.
So short answer to your question is that AMD cannot really make a great chip with new uArch from first try. If they would have succeeded to make rdna 1 what rdna 2 will be, then nvidia would have had a hard time competing with 2000 series. The 2080 ti would sell with 400-500$.
