Hi everyone,
I started playing around with 3D design. But rendering a scene can last for hours with LuxRender. So I'm looking for a solution to render scenes in the shortest possible time.
I was considering building a render farm with 6 nodes consisting of i7 2700k, but this would cost at least 3500$.
Now GPU rendering seems to have the potential to provide faster rendering while being more affordable. I have done a bit of research and here is what I've undersood so far : there are two serious options :
1) The proprietary option. NVidia card with Octane rendering. Octane is unbiased rendering and shows good results.
Issues :
- Octane is proprietary and costly, and so are plugins for it
- GTX680 has been stripped of computing power according to anandtech review, I dont know how much that impacts GPU rendering efficiency. But this would mean that I have to go for a "pro" Quadro card, which are much more expensive than the consumer version.
- I will be stuck with nvidia hardware
2) The open-source / AMD solution which is called OpenCL.
LuxRender already seems to support to some extent GPU acceleration with AMD GPUs.
But I already have a 5770 with a Core i7 860 and 8GB of RAM, and it's really very slow rendering. In a simple scene I get 0.3 samples/pixels/second on average.
This would be my preferred solution, buying a 7970, however it's really not that impressive so far compared to the videos I've seen of Octane providing almost instant render.
I'm interested in advice on Nvidia GPUs to consider, or if you know how to achieve faster render with the LuxRender/AMD solution.
Thanks!
