Did you all see that the 1 Quadro RTX 8000 was just as fast as 4 V100's in doing the Star Wars Demo?
 
So no idea what Stanford could do with that kind of power and AI and Tensors core but it could be awesome.

    I wish I could afford one, and will have to see what kind of craziness is in the GEForce lineup.

    Quadro did not seem well received - not really supported - when I was looking into them about 2 yrs ago, before buying my Titan X(p)
     
    The drivers that are specific to the Quadro can make them perform very well - at a significant price

    its only 4x as fast when under ray tracing (RT) loads. under non RT loads is where i really want to see how well it can perform, because that is where F@H will run. i strongly doubt F@H will ever update to where it could utilize the RT specific hardware, though i may be wrong.

    We need more specifics from nvidia about it. The ray tracing uses less precision as it's an AI style algorithm. The split between integer and floating point units looks interesting though. They could have increased the size of the floating point units to support the extra 8bit fp units Deep learning is all hot and bothered about.

    heck now we may even see the 2080 Ti launch monday as well! if so that will be unprecedented!

    would be nice
     
    Sure hope there are about 10K units world wide on Launch day & not just a couple hundred

    Since there are pictures of the MSI, Gainward, and Palit 2080Ti's out there, seems likely.
     
    I've been hoarding folding bucks since I bought my 970, looks like it's about time to spend them all.

    The Ti series is almost never the first announced. Probably be an xx70 and xx80 like Pascal's launch. The 1080Ti was months later.

    10 months later, nearly a full year. that is why it would be abnormal for them to do so and only one real reason i can think of to do so. not so great yields on these massive chips for the Quadro 8000 and they need to offload them somehow.

    My 1080Tis are working their magic now. Unsure if I'm gonna try upgrading this cycle. We'll certainly find out more on Monday, but I expect mostly marketing fluff. Many of the improvements are the result of dumbing down the floating point math to 16bit or even 8bit with regards to the fuzzy ray tracing. I can't wait for a good technical analysis of the impact of splitting the integer and floating point pipelines. Of course the impact on folding will take actual hardware to find out. Certainly Stanford won't be in a hurry to update their code.

    Dang is it interesting. The split on int and FP looks awesome on paper. 50% more perf across board supposedly. Wonder if folding can take advantage if it. The rest of it Tensor and RT units might prove useful in long term but I don't see any short term benefit as the coding is probably gonna be long in coming.

    One thing is for sure... we're due for a goal line push in February / March now.  Best keep an eye open for those killer 1070 / 1070ti / 1080 / 1080ti deals to make sure you don't have to drop a boat load of cash for Folding Year 12.

    Me too. I have to decide if I go for the current ultra card or wait for FTW3 to be available.

  • Microsoft® DirectX® 12 API, Vulkan API, OpenGL 4/5  -  This from EVGA's website.  I haven't seen anything about OpenCL support, it only talks about OpenGL.  Since I don't anything about this side of things will it still work with FAH with it needing OpenCL?  I was just curious, my pocket book won't let get any of these new cards this year.

    Depending on the F@H workload, splitting the int and fp units could have a great impact. Nvidia could implement their OpenCL driver to run int16/8/4 through tensor cores for an even more dramatic speed up. Folding performance on a new architecture is always hit and miss for a while.
    Nvidia really wants to keep the tech open (more demand) and building libraries for openCL is a must for researchers right now. How you have to access the specific features of the hardware for optimal performance is an open question. We haven't really seen the research papers and code libraries yet. Expect more details in the coming months.

    If they were going to use the Tensor cores, then the Volta that is already out would have a HUGE increase in score.  As it is, the performance increase isn't that huge, and the Tensor cores on the V100 cards are not being used.  Stanford would also need to redesign their cores to take advantage of the new hardware.  Currently everything is designed to run on Kepler, that is how far behind they are.  Not Maxwell, but Kepler, currently 6 year old architecture.  Stanford only has 1 programmer as they are either too cheap, or too underfunded to pay anyone else to update their code.  This was pushed hard when crypto was booming because of the sheer amount of farms using Pascal cards and they were told to update their ancient cores, and Stanford basically said "no", but not as politely.
     
    Stanford doesn't care about this new hardware, because the majority of users don't have it.  That's their attitude, and it won't change.

    Thats what I've seen from a few reviewers say.  Which makes since to pull the Titan name from the Gaming cards.

    Will see if it pulls 60fps 4k maxed in the new tomb raider. Probably won't invest otherwise.

    I'm getting fps in the 40s for the most part in Andromeda and Tomb raider. A good boost and nvlink might push it up. I'm not sure if I care about the ray tracing. I don't see a huge difference in demos unless it's tomb raider and super overkill. Dlss seems much better and I hope nvidia enables it for older games, but its dependent on them running it through the big box first.
    Unless there's a significant increase in fah output or some of the WCG projects can make use of the extra power I just don't see the point. Especially for folding, the slides showing a 20% to 60% increase for regular workloads looks quite inconsistent and remains to be seen how it stacks up. I can't wait for you guys to test it out. Since I like to wait for the hybrid cards there's plenty of time to see real results. Right now it is just a super hype train.

    Real Time Raytracing in the home has been a fascination for me ever since I saw this demo that was created on a Pentium 4 back in 2000
     
    https://www.youtube.com/watch?v=CFRZfCgIs2E
     
    That Nvidia managed to recreate cinematic levels of RTR (Yes, I know the framerates are limited at THIS time, give it a gen or two to catch up!) in a price range that will allow this tech to be put in the hands of the consumer? THAT'S the big leap in the technology for me.  Imagine the creativity that is going to come pouring out now with this kind of visual output available to the average end user.  Machinima will never be the same, for sure, and you better believe that Hollywood studios will be leveraging the technology as well!
     
    Now, imagine what COULD happen if a clever coder were able to take the AI decision making paths that RTX relies on and apply them to folding? THAT could be a game changer right there!

    i honestly could see a new folding core designed around the RTX as it has all these new features and will eventually be mainstream in another generation or two. though i wouldn't plan on seeing that new folding core till at least 2 years from now

    10 gigaray (10million?) is a far cry from traditional ray tracing. The 10Giga rays might even only refer to effective equivalence to traditional ray tracing for all we currently know. They are reducing the number of rays by an order of magnitude by reverse bounding the visible rays to the viewpoint.

    Giga is Billion not Million, so it's probably more in line with what you're expecting.
