Blender 3D animation and render comparison with Luxrender and SmallLuxGPU with OpenCL 1080p HD

CPU used was Q8400s and video card ATI Radeon HD4650 only 64bit video RAM system also had 4GB RAM but not very important.
My conclusion is that for animation Blender internal is the best since is much faster and has good quality no noise.
For still image the Luxrender and SmallLuxGPU will produce a more realistic image but it will take a long time to get a good quality image.
The use of GPU for render is a great idea but the OpenCL drivers are not that great at the moment and do not use the full potential of the GPU.
A high end GPU has a lot of computational power is just that it needs good programs to use that potential.
I used the latest beta versions of this software under Ubuntu 10.10

Blender 3D and Luxrender are free open source software they will work on Linux, Mac and Windows.
You can get pre-compiled version of Blender 3D at www.graphicall.org

 Мне кажется вы из России. Are you from Russia?

@wadyn95 No but close Romania.

This may be a question you do not have the answer too, but I know blender internal is faster on linux, is luxrender? I have been using blender for years but never used external renderers until now so I am trying to figure out the right combo of blender, os, and render engine for realism and speed. Thanks for any advice

[electrodacus]

@BsTn32508 I did not used windows in years so I do not know if is faster.

Luxrender is a very realist rendering engine but because of that is also much slower than blender internal.

I now use cycles is much more realist than blender internal but maybe not as accurate as luxrender still relay good and if you have an Nvidia card is relatively fast my GT430 is 2x faster than my Q8400 quad core and that is not a performance videocard.

You cab find Blender+cycles on graphicall website.

nice comparison :) i would recommend lux for high end results, but shame you didn't make a comparison with yafaray and cycles rendering engine witch is great alternative to smallLuxGpu since it doesn't uses gpu it uses only cpu, and it displays results in real time. keep up with the great videos

[electrodacus]

@r4jk3 I just purchased a GT430 and I was testing cycles it seems that on this low end GPU cycles is 2x faster than my Q8400s 4 core CPU. Cycles will only work with nvidia cards or CPU but GPU is much faster.

@agustinbs Yes you are right Blender internal renders in a different way and dose not have caustics this is the reason the blender internal dose not look as real as pathtracer.

Thanks for the comment. 

[agustinbs]

you used very specular scenes to test the renders, so the probability to find caustic paths like those hot pixels you get are very high, thats is one of the weakest aspects of a pathtracer render engine like slg and lux, so the comparison is unfair, also they are performing global illumination computing indirect light. and blender not.

But yes for animation, most of the case you will find better stick with blender internal.
