Titan RTX 24GB or 1080/2080ti?

edited July 2019 in Technical Help (nuts n bolts)

I have a 980ti now.
Most of my scenes involve multiple figures, rendering with the CPU and sometimes using as much as 40GB of system ram.
Which card would show the greatest speed increase, and what problems might I encounter?
I'm driving a 4K monitor with the onboard graphics chip, so no need for video outputs.
Win7, Studio 4.9.2.70, Intel I7 6700, 64GB RAM.

    For scenes that big a 2080ti might not have enough VRAM. Your options would be the Titan or Quadro's that have 24+ Gb of VRAM..

    enable a GPU render and start a render of one of your scenes, yes, it will drop to CPU which is fine. Stop the render and check the log for the entries that say how much memory iRay tried to allocate for the scene on the card. That should give you a rough idea how much VRAM you need. I also strongly recommend you consider Scene Optimizer before spending $2500+ on the Titan.

    Thanks. I'm using Scene Optimizer, it's fantastic. But many  of my scenes use multiple characters close up. I'll do as you suggest and check the log. Will I have any problems with a 2080ti in my current computer? I can move the 980ti to another one.

    And with so much in my scenes, Scene Optimizer takes a looooong time! Ordered SSDs, maybe those will help.

    You can also try doing multiple spot renders and then composite them together in post. I've done that before when I had a scene that was too big for my 1080TI (before I got scene optimizer). I rendered it in quarters and then they went together fine later.

    My problem is production time limits. I have to produce more than 4 images every day, 1800X1500, and setup takes a big chunk of time already.
    I would rather do less work than more.
    I've actually thought of building a duplicate system so I could alternate between the two for creation/rendering! But desk space is also scarce.
    So we're getting kind of away from the question, would the Titan RTX / 24 work for rendering in Studio in my current box without problems? I think that the memory would make it worth the price, all other things considered.

    Here it is, by the way:

    We don't know whether the Titan will work in your rig because the component that matters, the PSU, isn't listed. It should but it does draw some more power than a 980ti so it might not.

    As to production workloads, spend the money for Render-queue and render overnight. I set up scenes in the evening and they run overnight and while I'm at work. That keeps my rig busy roughly 24/7 and I don't waste my available time waiting on renders.

    It's an EVGA Supernova gold 850 watt. I'll buy a larger one if needed. I usually work on the previous scene in Paint.net while the next scene renders, and often have to stop the render to make a change.

    You should have no problem with installing a Titan with that PSU.

    As to fine tuning a scene and then rendering it. I do that too but I leave the full render until I'm done for the night and let them run to full convergence, or now with the denoiser to what ever threshold I find acceptable. You don't need to run the full render every time to see enough to adjust positions and poses.

    I don't think that version of Studio will support the RTX GPUs.

  • kenshaw011267kenshaw011267 Posts: 3,805

    True. You need 4.11 for RTX cards, and maybe for the GTX 16xx ones as well.

    Well, that kills that, then. Thanks.
    What about the Tesla M10? I can get one with 32GB DDR5 for about the same cost, and the lack of video outputs wouldn't be a problem.

    Or the M40/24GB for $1000.00?

    Or a K80/24 ditto?

    Or, to put it simply, what are my best hardware options for speeding up my renders? Sticking with my current software.

    Thanks to all who've replied so far.

    Go for the 1080TI (11GB VRAM) using this NVIDIA display driver
    version: 419.67, only the driver installing, DO NOT install all the other software who comes always with!
    if you have the money for an RTX 2080Titan buy two 1080TI (around 1000$) and spend the rest of the money for some nice holiday, just saying laugh.
    with the 4.11 Daz3d version
    use Iray and stop rendering on CPU, 
    just slows all down, even the GPU
    Why no CPU Render? That's simple!
    For example, in the same time, the GPU is doing 3710 iterations
    the CPU makes just 200 +-.
    And if you render with both, CPU and GPU, your whole system slows down, just because of it.

    You creating a bottleneck and he is called CPU. The ram on the mainboard, the GPU, hard drive,

    just about everything is waiting for the CPU til its finely finished with just 1 iteration for each core

    and therefore is also the Render time slower.
    it's .... as ..... I .... would.... write .... just ..... like .... that.
    Yes, an Intel system is less affected by that than an AMD system, I know, I have both of them, intel is just better in hiding it, but still...

    I hope this will help, not only for you!
    And remember, display driver, important, if you decide to go with any of those 1xxx GPU cards and 4.11.xxxx DAZ.

    sorry for my bad English but I'm not a native.

    Thank you. I might have to go with a 1080ti, but I'm hoping for a way to have more video RAM.
    Cuda cores don't help if the scene won't fit on the card. I'm using Studio 4.9.2.70..
