Review: Nvidia Turing architecture - GeForce RTX 2080 and 2080 Ti

by Hilbert Hagedoorn on: 09/14/2018 02:00 PM | source: | 130 comment(s)

As time closes in on the actual performance reviews, today we'll be taking an architectural deep dive into the Turing graphics processors, and of course, we can share with you all specifications, you know the nitty gritty stuff. We'll also present an in-house photo shoot of the cards that have arrived already.

Read the article right here.

I like the look of the Duke better than the Gaming Trio.

DLSS =
- Take angle under which 2 edges intersect
- take color information at edge
- load resulting pixel values from database

Variable rate shading =
- 1/2 precision
- 1/4 precision
- 1/8th precision
- and lovely 1/16th precision
This for sure boosts performance. Gamers will have mandatory camera tracking their eyes...

TSS =
- Bake in results into texture on the fly
- use old information to skip actual work
- update baked in texture from time to time (or at rate you feel comfortable with)
- probably would not be as bad as it seems if we had higher than 16xAF

To sum it up: New features can be paraphrased as "Way to cheap out IQ for performance gain."
Maybe good for 8K, somewhat OK for 4K. But hit to per pixel quality on 1440p will be unpleasant. On 1080p unacceptable.

Same here, Duke all the way. Regarding the architecture, it's clear where the gaps are that will be filled by the 2080+ and the Titan X (looks like there won't be a 2070 Ti). Anticipation for the reviews at like at 11.

Wow this 2080rtx is crippled like shit with tensor cores compared to TI variant nvm 2070..

Yeah, comparitively small gaps between 2070 up to 2080, and then 2080ti comes along & massively increases the gap in specs.

I like the look of the Duke in comparison with the other MSI card, like someone already mentioned, I also like the NVidia Founders aesthetic. Looking forward to the reviews, and will read up on the associated tech of the architecture a bit more once the card reviews are out, I understand/know some of it, but not all.

The dlss comparison shot is really tiny.

At least this way 2070 won't be made using second-rate chips that weren't good enough for 2080.

@Hilbert Hagedoorn

Thanks for the article.

Can you post the full photo of DLSS comparison?

Also can you comment on this

"Another important change with NVLink SLI is that now each GPU can access the other's memory in a cache-coherent way, which lets them combine framebuffer sizes- something that was not possible with SLI before. The underlying reason is that the old SLI link was used to only transfer the final rendered frames to the master GPU, which would then combine them with its own frame data and then output the combined image on the monitor. In framebuffer-combined mode, each GPU will automatically route memory requests to the correct card no matter which GPU is asking for which chunk of memory."

You said that RTX cannot share memory.
Is this a software limitation where shared memory-access is limited to 'prosumer' cards?

First of all, very nice article, i managed to understand most of it... Can´t wait for the review!

That Duke card is really a looker although my Duke card looks even better. Too bad MSI managed to ruin the looks of the gaming version... Nvidia´s FE look a lot like the cards from Pallit, at least to me.
Also 79$ for a SLI bridge??? Nvidia needs to stop copying Apple´s business practices...

just wow at these prices.

given that there is no need for any of these products the enthusiast market will quickly be tapped. and this is exactly why the 10xx is slow-walking its E.O.L.

even a competitive gamer can buy a 1080ti (at the lowest ever price) for half as much and have better performance in some scenarios.
my gawd, you can even buy a 1080 and a g-sync monitor together for less money... i'm shocked i can even say that.

all of this just to beat out C.E.S. and AMD's announcement of the first mid-level card with high-end performance.

Yeah, what gives these prices? They´re stupid man...

For real, i can remember a time not too long ago when the top dawg went for 600 bucks.

Great job Hilbert!

I know that everybody is justified to talk about the prices, but the tech itself looks crazy, I am genuinely impressed, especially considering that Nvidia didn't have to innovate at all. Pascal with +40% Shader engines would be enough for everyone to be satisfied, and much cheaper to produce.
Applause for the leather jacket.

I expect the initial benchmarks to be underwhelming, as this is a new architecture, but if Nvidia has a good driver for this at a point, it should be night and day with Pascal. The potential of the Tensor cores alone is insane.
