Nvidia’s Turing Architecture Explored: Inside the GeForce RTX 2080

Ray Tracing And AI: Betting It All on Black

Nvidia could have poured all of its efforts into features that make Turing faster than the Pascal architecture in today’s games, rather than splitting attention between immediate speed-ups and investments in the future. But the company saw an opportunity to drive innovation and took a calculated risk. And why not? Its performance and efficiency lead over AMD’s Vega RX series creates a comfortable margin to push next-gen technology more than we’ve seen in years.

Dedicating gobs of transistors to Tensor cores and RT cores doesn’t pay off today. It doesn’t pay off tomorrow. Rather, it pays off months or even years down the road as developers become comfortable optimizing their games for a combination of real-time ray tracing and rasterization. Nvidia needs them to spend time experimenting with neural graphics and AI. Technologies like mesh shading and variable rate shading aren’t used anywhere currently; they require adoption and support. With all of that said, developer enthusiasm for real-time ray tracing appears unanimous. This truly seems like a vision everyone wants to see realized.  

In the meantime, gamers aren’t going to spend their hard-earned dollars on a future promise of better-looking visuals. They want instant gratification in the form of higher frame rates. We can talk architecture ad nauseam. However, the features found in today’s discussion only amount to half of the story (the academic half, no less). In a few days, we’ll have a battery of performance, power, and acoustic results to present. Only then can we tell you if GeForce RTX 2080 and 2080 Ti warrant the high prices that have enthusiasts gnashing their teeth.

    "And although veterans in the hardware field have their own opinions of what real-time ray tracing means to an immersive gaming experience, I’ve been around long enough to know that you cannot recommend hardware based only on promises of what’s to come."

    So wait, do I preorder or not? (kidding)

    Well done article Chris. This is why I love you. Details and logical thinking based on the facts we have.

    Next up benchmarks. Can't wait to see if the improvements nVidia made come to fruition in performance worthy of the price.
  • Lutfij
    Holding out with bated breath about performance metrics.
    Pricing seems to be off but the followup review should guide users as to it's worth!

    i didn't expect the 2070 to be on TU106. as noted in the article, **106 has been a mid-range ($240-ish msrp) chip for a few generations... asking $500-600 for a mid-range GPU is insanity. esp since there's no way it'll have playable fps with RT "on" if the 2080ti struggles to maintain 60. DLSS is promisingly cool, but that's still not worth the MASSIVE cost increases.

    It is possible that they are changing their lineup scheme. 106 might have become the low high end card and they might have something lower to replace it. This happens all the time.

    turing does seem to have the ability to pump up the fps if used right with all its features. I just hope that nvidia really made a card to power up its upcoming 4k 200hz hdr g sync monitors. wow, thats a mouthful!
  • anthonyinsd
    ooh man the jedi mind trick Nvidia played on hyperbolic gamers to get rid of thier overstock is gonna be EPIC!!! and just based on facts: 12nm gddr6 awesome new voltage regulation and to GAME only processes thats a win in my book. I mean if all you care is about is your rast score, then you should be on the hunt for a titan V, if it doesn't rast its trash lol. been 10 years since econ 101, but if you want to get rid of overstock you dont tell much about the new product till its out; then the people who thought they were smart getting the older product, now want o buy the new one too....

    I see a lot of features that are seemingly designed to save compute resources and output lower image quality. With the promise that those savings will then be applied to increase image quality on the whole.

    I'm quite dubious about this. My worry is that some of the areas of computer graphics that need the most love, are going to get even worse. We can only hope that overall image quality goes up at the same frame rate. Rather then frame rate going up, and parts of the image getting worse.

    I do not long to return to the day where different graphics cards output difference image quality at the same up front graphics settings. This was very annoying in the past. You had some cards that looked faster if you just looked at their fps numbers. But then you looked at the image quality and noticed that one was noticeably worse.

    I worry that in the end we might end up in the age of blur. Where we have localized areas of shiny highly detailed objects/effects layered on top of an increasingly blurry background.

    I have to admit that since I have a high-refresh (non-Adaptive Sync) monitor, I am eyeing the 2080 Ti. DLSS would be nice if it was free in 1080p (and worked well), and I still don't need to worry about Gstink. But then again I have a sneaking suspicion that AMD is going to respond with 7nm Cards sooner than everyone expects, so we'll see.

    P.S. Guys the 650 Ti was a 106 card lol. Now a xx70 is a 106 card. Can't believe the tech press is actually ignoring the fact that Nvidia is relabeling their low-end offering as a xx70, and selling it for $600 (Halo product pricing). I swear Nvidia could get away with murder...

    4nm is no longer considered a "Slight Density Improvement".

    Hasn't been for over a decade. It's only lumped in with 16 from a marketing standpoint becuase it's no longer the flagship lithography (7nm).
  • TMTOWTSAC
    In a perfect world, the non-RT models would be based off the TU architecture without any of the RT silicon, and priced accordingly. They're claiming RT is the must have feature and subsequently worth the price premium. Given those claims it's going to be very interesting to see what pricing scheme they go with for the non-RT models.
  • mlee 2500
    Great article, very informative, thank you for taking the time to write it.
  • dimar
    No need to waste your hard earned money. AMD Navi is around the corner. And if Navi isn't that good, RTX prices will be lower by then. With AMD you get freesync which most monitors have these days.
  • Reynod
    Fantastic read as always Chris.

    Objective, with warts ... an easy read ... informative ... with detail.

    I hope you are editing the article that gets released here with the benchies once the NDA is lifted.

    I will spend money based on that content ...
  • cangelini
    Thanks guys.

    Yes, I will be spending a long caffeine-fueled weekend with graphics cards, Excel, and Word. Let me know if there are any specific requests on comparisons you'd like to see made!
  • truerock
    I've been running my Nvidiia Geforce GTX 690 for 6 years. It does 3840 x 2160 at 30fps.
    The lack of HDMI 2.1 is just enough of a negative to keep me from buying a Geforce RTX 2080 Ti.
    I guess it is ironic that I actually don't want HDMI or DisplayPort outputs on my Nvidia cards. I want Nvidia cards that only have USB-C output ports.
    Oh well - maybe next year. My Nvidiia Geforce GTX 690 will be 7 years old.
  • truerock
    Chris,

    Thanks for the review. It's the best I've seen on these cards so far.

    I'm interested in 3840 x 2160 at 120fps. That would be with the more popular games. What settings for a specific game allow 3840 x 2160 at 120fps vs 3840 x 2160 at 60fps and 3840 x 2160 at 30fps. I'm not interested in g-sync. Does graphics quality suffer much as settings are pushed down to allow higher frame rates?

    Crysis @ 4k? ...you know someone will ask it. And Anandtech tested it on the Titan V, so we can compare.

  • cangelini
    Before they did that, I did this: https://www.tomshardware.com/reviews/crysis-10-year-anniversary-benchmarks,5329.html ;)

    Time's going to be tight, but I'll see if I can throw it on the test system.
  • Reynod
    I agree ... if you still have the Original Crysis game ... then answer "But will it play Crysis?".

    The original Badly coded game please?

    I imagine you will alsso have received a couple of iterations of drivers since receiving the card, so let us know how much improvement you found with these?

    Finally, when you finish can you pull the HSF off and let us know anything about the TIM you find?


    :)

    Uh, it should be comparable to the other Crysis benchmarks, please.
  • Reynod
    Ok then both of them ...
  • kyotokid
    ...well the 2070 sounds like the RTX stepchild. No linking capability which means no way to improve frame rate. So my thinking is who would buy this card?
  • Crazyjay53
    So why so hurry getting these cards if there any game that run on rtx , it gonna take awhile for game software to add it in game ,ill stick with my 1080ti for awhile till they get benchmark on those rtx if they are worth it
