    Arabella 7, Jade Scalp Hair, Something Wicked Set. No other items in. 

    W:1600 H:1200 dimensions.
    Base Render settings, no Optix. HDRI map.
    Reached 98% convergence in 3 minutes 12 seconds. 
    And While I was using the PC and had 2 monitors active.

    A quick setup. 

    Thanks a lot for testing this out. This is awesome results.

    It appears that from my initial testing, the GTX 1080 is around 6~10 times faster than CPU rendering with an i7-6700K. 

    Is there some proper way to test this? Like a certain scene I could render and we'd check how fast it reaches 1000 Iterations?

    there is a speed  comparrison thread with a default scene somewhere

    @SickleYield, I think had a test scene in one of the threads here, or probably available at her deviantART account, too

    I was just about to buy a desktop today with a GTX 980Ti. If someone could post GTX 1070 benchmarks as soon as possible that'd really be appreciated.

    Thanks, I'll post the result when I come back from work.

    ..until your scene exceeds the VRAM, then all those CUDA cores mean squat..

    indeed

    ... But we've agreed on this elsewhere. :)

    Not bad, but I had hoped for better than that. I pretty consistently get a 10 times speed increase over CPU alone on my GTX970, and I had hoped a 1080 would do better than that.

    Yup, if I only got that, I'd be returning it; 980ti does considerably better than that. and costs less; so I'd be interested in seeing folks post comparrison between their system on old graphics card (970 and 980ti for preference), and what they get with a 1080.

    As it stands, Xeons are looking like the way to go.

    Depends what CPU you are comparing it with. If I was to consider my old CPU, this card is 35 times faster, but that means nothing.

    I posted the results on the test scene thread. That will be the most accurate way of testing the performance when we all have the same scene.

    I noticed Terradome renders way faster just with the new Iray... although I get the minecraft water reflection in my test render like you did too.

    Unrelated to the 10?0 speeds, does that 'minecraft water' effect (love the description!) go away or reduce if you subdivide the water?

    Well what a shock, out of the blue with no warning. I wonder how long it will stay in beta.

    Now does it render exactly the same? Or are there some changes to how it handles something, like sss in 4.8. Is memory usage the same? If it is faster in CPU mode, then something has to be changed.

    I have the now old 4.9 beta. How do I go about getting the new beta? Does it replace the old beta?

    ...well I just ran a test render on the CPU on a scene I rendered a few days go in 4.8 and there was a noticeable difference in render time.  The 4.8 version took 1 hr 29m 29s, in 4.9.3.117 it took 51m 44s. I made no changes to the file or the render settings just loaded the scene and clicked ""render".

    In DIM, change your settings to "public built" and you should see the update for DS4.9, also with the 4.9-Beta updates for various plugins, if you own them.

    I would also like to try my 1070 at last, and then, I loaded the DS beta, and when it's loaded, I just see a grey plane or whatever on the viewport sections.

    I can't see the move/zoom/pane... etc of the camera, nor the selection of the cameras, or the type or render. And If I render I just see the same grey plane. I never get to see the grid or the icons to navigate.

    Have you updated Nvidia drivers for your 1070 card?

    Windows or MacOSX? As far as I know, it does not work on Macs, yet.

    Is the viewport actually open? It should ahve a tab with the name at the top of the space. If not, Window?>Panes(Tabs)>Viewport and drag the top of the frame (not the tab) to the top of the space to dock it as a new group in the central well, you should see a line in the highlight colour when you are in the rigyt place to drop it.

    Yes, the old beta will be replaced with the new one.

    I thought that would come open, thank you Richard!!! now to dock and try my 1070!!

    ...that's a lot of reflective surfaces in theat lat one. Interior shots still seem to take more time than exterior ones.

    Are the lights all emissive?

    I had a scene render two minutes faster 18 versus 16 using a 980ti, so tbh, I'm not impressed with the new 10 series cards, seems to me all hype, and little substance - certainly if considering the outlay.

  • kyoto kidkyoto kid Posts: 42,132

    ...the advantage with the 1070/1080 is having 8 GB instead of 6 and not having to pay over 1,000$ for a Titan X. The only other Nvidia GPU with 8 GB is the 2,500$ Quadro M5200.  AMD's had an R9 Radeon GPU with 8 GB for a while which costs less than a 980Ti, but that is useless for Iray.

    Back when there were rumbles about a the forthcoming Maxwell 970 and 980, there was a lot "talk" they would be both "upgraded" to 8 GB.  Was very disappointed when they came out, especially with the price of the 980Ti. 

    8 GB is reasonably sufficient for a fair percentage of my scenes. Just have to remember not to "downgrade" to Windows 10 or the 1070 and 1080 become 6 GB cards.

    Yes, all lights are emissive - around 30 of them, according to Iray Light Manager PRO
    http://www.daz3d.com/iray-light-manager-pro

    For me it was a big upgrade, to get GTX1080. Previously I had GTX670 with 2 GB of VRAM, so I have not attempted to render such a big scenes before.

    ...yeah, that many emissive lights would slow rendering down something fierce.  I was wondering where you got that nice display and then saw it was the Iray Light Manager, a tool I do not yet have. 

    On my system (CPU mode) with that many emissive lights plus all that reflection going on, maybe 10 or 12 hours.
