I only have the reference of Luxrender and the highest ray firing rate I've seen was about 40 million rays on a 2x5870 + 7970 + i7 3930K system.

 

Was that all the cards putting all their resources into ray-tracing?

And the i7 3930K. Luxrender is a seriously impressive piece of software.

Go to 3:10 if you want to skip other features.

That is definitely interesting. Presumably this would be an PCIe expansion card? If they could get away with x1 slot then I would see good number of games grabbing one if it's cheap enough and benefit is visible enough. Say, ~50 EUR and using x1 slot, a lot of people could grab that. At, say ~300 eur and needing x16 slot the market would be a lot smaller probably for just prettier shadows. Well - not only prettier shadows tbh - I myself would be a bit more interested in accurate line of sight for AI units.

Sincerely I see a lot of applications of this for enhanced reality, driving aid and other minor stuff like 3D scanning.
post #25 of 33

Very nice. In that case this ray-tracing chip isn't just "miles better" but a whole order of magnitude better - Which is just awesome to think about. It can't get into consumer GPUs fast enough.

As long as there is Lite-Coin, this idea doesn't stand a chance...

Well, there are vastly faster "single-tower" systems what the one with 3 GPUs you are describing, plus there are distributed over network GPU accelerated renderers.



Now, lets see if we can squeeze 7-8 of those PowerVR babies in that Tyan FT77A. thumb.gif

Well considering a Titan uses 350 watts and Rogue generally uses less than 15 watts you wouldn't even need to pack them in all that tightly for some pretty cool results. My brain can only imagine though how awesome it would be to have equivalent wattage from Wizard as a few Titans packed into a box. 20x cards * 6 = 60x rogue chips equivalent to 6 titans. 60 * 300 = 18 Gigarays per second.

With 18 Gigarays you could have 18,000 Megarays / 2 megapixels (1080p) = 9,000 rays/per pixel /s divide that by 30 frames per second and you're looking at 200 rays per pixel per frame. That would be a little grainy but pretty close to a production quality rendering in real-time.

Best first post I've ever seen. +rep :thumb:

 

I still don't think it's fast enough to render all the cash draining out of your wallet though.

Well, it will be some time before it is accessible for "small-time-crooks"...
Those that do care though (e.g. movie and tv studios), would be willing to pay dearly for it starting day 1.

As for the rest of us, Soon™
