With one GTX 480 this may render for about 10 minutes, if you add 2 you'll see it for 5 min tops , add more till you get it for 5 seconds , and if you add MLT you get noise free render no time

But why so bright? And not the same DOF

because I didn't get your exact parameters
I redo with yours and always 30m12s

so...the 470 should do it in less than 20 minutes...not bad

I think (hope) less

Not only cuda core, but a new Fermi architecture.
I'm waiting some 470-480 test too.

Hi cecofuli, thanks for posting this!
I work at a 3D architectural studio that uses Vray, and have been, well...nagging them, haha, about GPU rendering for a while. Octane looks very promising, and has caught their attention, but there are no direct comparisons between it and Vray for speed.
Any chance of a benchmark version that could be used for comparing the two? That would really be great, so I could show some hard numbers and facts

This is supposed to be so much faster, but I gotta prove it!
Thanks,

You can't compare a biased CPU engine and an unbiased GPU engine
But they will dev VrayRT on GPU wich gonna be awesome
Its not a competitor of Octane since its gonna be biased
And its not node based, not standalone etc...

Sam- haha, yes, of course this is not really an exact comparison.
Maybe I should clarify- a benchmark to compare the time taken to get an image of equal quality and appearance from both.
Obviously there area billion and 1 factors that could fudge the numbers around, but if it's something like 10-20x, or even just 5-10x faster via Octane, with only basic calibration, then that's a solid ZOOM ZOOM number, no matter how either side is tweaked.
Currently making a simpler version to play around with on my GTS250 when I get home...

Oh, and it IS a competitor!
If we could get the same quality image, in less time, plus the huge advantage of a realtime viewport- this would save hours upon hours of work (and frustration). We use Vray RT, but it's not all that great, and Vray GPU seems to be slowww dev.
The issue is, the hours saved during render really DO need to be a lot, in order to compensate for the more complicated workflow. Hence, the need to compare speeds
