This is more fitting for the off-topic section, not Octane Renders General Discussion section.

You're right.
Don't now how to move it or delete it though...

Already done.

Thanks!

Im very interested in this stuff.

Have you seen this?

How can it be that fast? Could it rival octane?

[RobSteady]

Yep, it's fast and has a lot of interesting features!

They've obviously spent a good deal of time and effort developing their algorithms. Also, it can combine both unbiased and biased modes (or use one or the other). I can't tell from this video if it's strictly unbiased here or using a combination, but if so I'd guess irradiance caching is only used for one bounce since there's no splotchiness going on. If it's all brute force, even better, considering this is on a 6-core machine.

Could it rival Octane? Well, that really depends on what ones goals are, and also their hardware limitations. As far as image quality, Corona seems to be able to hold its own, at least that's what Peter Guthrie's recent project with The Boundary seems to indicate. Bertrand Benoit has made some extremely nice renders using Corona as well, also Octane I believe. So, I'd say yes it does rival Octane there, but so do other renders.

Pure speed? Can't say as there's no MODO plugin for Corona for me to compare.

Features and simplicity? Corona materials and rendering seems to be pretty straight forward and uncomplicated, even the GI cache settings (for an unbiased renderer). As far as features, I think Corona absolutely rivals Octane. In fact, being CPU-based, I think they have an advantage in ability to add new features more easily that developing for GPUs.

The one area where Corona clearly doesn't rival Octane is in the plugin and platform options. Corona doesn't even run on OSX at all, never mind have plugins for MODO, Lightwave, and other DCC apps.

But I mean, the thing of the gpu is that it is fast, faster than cpu.
but now, if the cpu with corona can reach octane then whats the point?

If you've already got a beefy CPU, there could be no point. But there are two things that go in the GPUs favor: 1) parallel processing power seems to be increasing in GPUs at a rate that CPUs used to, and 2) adding or upgrading GPU hardware can be considerably easier and cheaper.
