Iray and the GTX970

Just curiious how much faster will the Iray renders be with a GTX 970 video card? I am using the 8800GT 512mb right now and I only get like 1-3 itetrations each update. Will the GTX 970 make huge difference, or is CPU the biggest factor?

    It should make a huge difference -- the 8800GT only has 112 CUDA cores, the GTX970 has 1664.  And you'll be able to fit much more in a scene with 4GB of RAM than with 512MB.

    Thanks for the confirmation, Fixmypcmike! GTX970 purchased!

    You'll likely be very happy with it, I was and still am. :)

    I have it as a secondary card; so it is only used for rendering; don't set up SLI and continue to use your 8800 for normal use, although your normal Daz usage would likely benefit from the faster card. I use a GT 640 with 2GB GDDR3 of memory for normal use and it does get laggy at times when I have large scenes loaded in Daz. But I prefer the 970 to be purely for rendering.

    I have a scene based on Stefan "Stonemason" Morrell's Streets of Old London.  On my old PC (3.4 ghz I5, motherboard graphics) this took 15 hours to reach an acceptable quality.  On my new PC (4.0 ghz I7, 970 GPU) it took 1 hour 6 minutes!

    Cheers,

    Alex.

    Take a look at this thread on Share CG in which SickleYield has uploaded a bench mark scene.

    You should be able to see the contrast... that last one is my rig with a GTX960...

    Probably too late to benchmark your old card? Anyway you should be able to benchmark you new card against this.

    Depending on your ram generation, processor core count and speed using the CPU may or may not help - its one you need to test.

    More for others that are curious but I also found out that PCI 3 cards go fine in machines that are PCI 2 as they are forward and backward compatible codex. An older computer at home's GPU died and I could not find any Nvidia GPU's at my normal wholesaler in stock still on PCI 2 (GTX570 etc.)... SO i grabbed a nice new card on PCI 3 and it made the machine rock!

    I'm now using 2 970's and I used to render on an AMD laptop....lol yea its fast but i also have an I7 cpu. I don't know what just one would do but I'm sure it will do better then what you have now.

    Most renders I have done are between 1/2 hour to an hour no matter what I have in it.
