IDF 2010 - Ray Tracing with 80 threads

http://www.tweaktown.com Next up we get a demonstration of the raw power of the Xeon platform in the form of four Intel Westmere EX processors. Each CPU has 10 cores per chip with Hyper-Threading enabled giving us an insane total of 80 processing threads to work with on a single system. If you don't know, that is an insane amount of processing power. What do you do with all that power? You show off some amazing fully CPU-powered ray tracing in the form of a program called KeyShot by the folks over at Luxion.

We get a look at KeyShot which is real-time racing tracing software that only uses the CPU to do its work. What is displayed it the production of photo realistic images. And when we say that, we mean it. The chap from Luxion adjusted settings such as the index of refraction (Ior) of glass on a chess piece and it impacted its immediate vicinity according. There are a couple other neat demos in the video, too. Distributed by Tubemogul.

@BassPounderX 1000 years lol, more like 10 :D

@volatilecolon Wouldn't it be a better idea to figure out how to make gpus with a lot of VRAM then?

[truckcompany]

Cant wait for games to use this technology in real time. I would probably be over 50 tho :(

[airsombra]

I was expecting real time.....

[marcusbenhurr]

while watching this my computer had 6 BSODs...

250000 ram free thats like WTF supercomputer i have like 0 free D:

This is a very "soft" video. =p

[ulkord]

@TitanaMaster everyone knows that its not 60 fps. also everything is realtime. just like a very renderheavy scene would be like 1 frame / minute

[ulkord]

@MouthofSaurons no because for games you wont use these kind of textures

[josepena1127]

This video went viral on Sao Tome and Principe

@Subskil Well we've been doing that now for years, every video game renders an environment in realtime. You never stated the rendering method. I'm guessing you mean using this realtime ray tracing method, then yes, it's only a matter of making better computer hardware.

@ShadowriverUB I don't think you read the comment I replied to. The person stated that GPU's were way faster than CPU's, but are limited by their RAM. I simply asked if it wouldn't be better to then make sure the GPU's weren't limited by RAM.

Also it's not true that Windows uses all the RAM for nothing and forces applications to pagefile - it simply fills up unused RAM with commonly used files for faster acces, but that RAM will be instantly flushed when an application needs the ram.
