You can download the .max file and convert it for Octane. =)

The Octane test has GI clamped to 1. It means almost zero caustics.
You can't compare 6 fastest gpus with a good dual Xeon rig.
Less noise, less heat, less power, less space.
The good side of gpu render is that we can replace our gpus. After 4 years of 24/7 of 4xGTX580s usage I can replace all of them with 4 Titans X and get 2,2X speed.
It's not true that the Titan X is fast as the Titan Z. Titan X is slight faster than the Titan Black, not 2X.
The bright side of gpu computing is the feedback. With Corona 1.0 we have a good rt feedback but not comparable to the Octane rt speed with 4 Titans.
I don't know if is possible to port Embree on gpus, I know that Thea did it.
The light distribution in Corona is better than the Octane one but the PMC (sort of Metropolis lt) produces incredible renders and we can use pmc always in realtime.
Never say never.

Buy CPU's that are equal price to 4 Titan GPUs and then do interactivity speed comparison. You will get dual Xeon machine for that price. Let alone it will eat a LOT less power, which will pay off on energy bills.

We got 48thread dual Xeon machine at work, and feedback is almost realtime in exterior scenes, and still reasonably fast in interior ones.

also embree will be never ported to GPU, as it is highly-specialized CPU code, plus... you know... it is being developed by Intel...
Rendering is magic.How to get minidumps for crashed/frozen 3ds Max | Sorry for short replies, brief responses = more time to develop Corona ;)
