Sorry, my bad. It's 100 hours per frame for modern CG.

And that's on 40,000 high powered Xeon CPUs.
yeah no i think you're wrong. It's probably that long for a frame on a single CPU.
If not the film would have to be rendered for years.
ps : 100hours still seems massive even for top notch CG. I believe Pixar's movie frames "only" takes a few hours to render.
