Octane Render test with 3x EVGA GTX 780 Ti's

This is how Octane Render performs with 3 GTX 780 Ti’s using the Octane Render sample projects. It is blistering fast real-time speeds!

SLI is disabled in the NVidia control panel in case you’re wondering.

I will probably end up water cooling the GPU’s to keep temp and noise levels down but so far I’m very pleased with the benchmark results across various programs that utilize CUDA core technology for GPU accelerated performance.

Computer specs:
Corsair 900D case
ASUS Maximus VI Extreme motherboard
Corsair H100i liquid CPU cooler
Corsair SP120 fans
Corsair AX1200i power supply
i7 4770k CPU
3-way EVGA GTX 780 Ti ACX SC GPU’s
G.Skill Trident X 2400 32GB RAM

  • That is pretty sweet! So, you have three 780 Ti cards, but not in SLI mode per your description. Does the PC just utilize any GPU that's there, I suppose? I'm guessing SLI doesn't help?

    As a side note….work on fewer ahhhhhhhhs and uuummmmms in your videos…especially doing the croaky thing with your voice, haha. Good content, just a bit difficult to listen to. 😉

  • I'd like to start in vfx/3D and I need a good PC for around 600$.Using old high end graphics cards (2x780ti) seems to be a good idea they are very cheap (2 used for 180$ ).
    Have you got some advices for me please?

  • @aedrah, no the SLI bridge is not used for rendering programs. That is more for a gaming thing.

  • Do you have all 3 cards connected to the SLI bridge hardware to get this rendering to work?

  • Do you think that it's better to go with a single Titan X or 2*GTX 980ti ?

  • Rodrigo, for whatever reason I can't reply directly to your comment. Octane Render, like many other renders, uses the card with the least amount of VRAM. It does not add VRAM per each card. My scenes are typically not heavy enough to fill 3GB so that is why I didn't go for 6GB cards. Until there is a need for that much memory it's just a waste in terms of cost per performance.

  • I have a doubt, with 3-way 780Ti you are going to have 9GB of memory or just 3GB, like in games? Does Octane split the task in between the VGAs and multiple the VRAM? Do the Octane files easily reach 3GB? I have a friend who is building an Octane rig and he is not sure about the VGA configuration, especially how Octane reads the VRAM.

  • How are you liking this setup? Used octane in the past with 2 gtx 480s, wondering if i should go for quad titan blacks or 780 tis

  • is just one 780ti enough for animation?

  • I also got a GTX 780 TI but from Palit, I read on the internet that there isn't support yet for the GTX 780 TI and CUDA. Do you know anything about this? Thanks

  • Listen mate, I love that you are throwing your system out there for people to see how amazing it is – But if we system builders are to understand the data we recieve, we need something to compare by. You just showed how amazing your system is, but how good is it COMPARED to doing a single 780 Ti or something like that? Give us benchmarks mate..
