Forums - PC - Sweeney: 5000 TFLOPS to reach "reality"

mrstickball on 23 April 2013

I'll have that much GPU power in a few months with my project. Too bad its on a ton of GPUs rather than a single system.

Still, I'd love to know what kind of graphics 5x ATI 7950s would get..



Back from the dead, I'm afraid.

What kind of processing power in FLOPS does Pixar's Renderman farm give out?

Not sure but:


The Weta render farm that made Avatar was ranked 194-198 in Top 500 November 2009 list.

Avatar used all of the power available at the time thats about 300 teraflops peak performance. For comparisson the HD 7990 has 8 teraflops. Quad SLI Titans would give 18 teraflops thats the best you can get in a modern PC today.

And it still takes an hour to render a frame!

Jup thats true. Its amazing how much ressources Avatar graphics need but there is still hope.

A  lets say 300 tflop chip is way more efficent than a 300 tflop renderfarm that spreads the workload over 30000 CPUs. The ways of communicating between the chips takes ages compared to a single chip and the overhead is gigantic. A 300 tflop chip could do that work faster than 1 hour. But still not fast enough for games I guess, atleast not with movie production standards.

There's more too it than that.  I think games can match Avatar graphics pretty quickly.  The trick is LOD systems.  Avatar probably isn't using any, everything's rendered in high res regardless.  Atleast that's what I suspect.

I suspect so too. They don't cut corners when making a movie.

Yeah, there's a lot of theory about pixel resolution and how much resources a model should use within that pixel count.  Having a 100k polygon model won't look any better than a 10k polygon model depending on how many pixels the model will eat up.  But with movies, since they have the render time, I think they just make all assets and call it a day.  This is why polygon tesselation and possibly voxel rendering will be so important with the upcoming hardware.  What we've seen in PC games is just the beginning.

 What no ? I don't get it.
