[tgdaily] Nvidia GPU physics engine up and running, almost - Page 3

Intel offers up a proof of concept demo showing that their future architecture has expanded capabilities that will allow it to perform GPU tasks in the future, and nVidia responds by showing off their unreleased, flagship, discrete GPU. Big surprise, it does physics and rendering better than the CPU . Frankly, I'm surprised that the 9 series was only 10x faster than the CPU.
it was no flagship... it was not an unreleased card. It's software, to be honest there was no difference between a phyX card and a graphics card, I'd go as far as to say that the graphic's card are better at it since they are generally more powerful.

sounds like a new version of SLI on the way.. one card does GPU work. one does PPU work. all on 2 GPU's

interesting none the less =D maybe something to max out crysis?

AMD (graphics) rigs requiring Physics cards to keep up? Interesting thought.

150 people? Why keep so many significant figures when dealing with integers.

Guessing it should read 150,000.
How did that company survive with only 150,000 sales is my question.

Woops double post, please merge.

We were not really surprised to hear that it took just a month to convert PhysX from a stand-alone API to CUDA. After all, PhysX is a well-known multi-platform physics engine, as it is used in more than 140 games in development and number of registered developers tops out 25.000 figures. CUDA is supported by the GeForce 8 series and up (in all seriousness, don't go below 8800 if you want to play with CUDA), Ageia is now looking into expanding its user base from 150.000 to more than eight million, we heard.

In order to demonstrate the physics horsepower of the GeForce 8800/9800 series, Hegde took aim at Intel's eight-core Nehalem particle demo, which can be seen in one of our IDF articles. Back in Shanghai for IDF Spring 2008, our own Humphrey Cheung filmed Intel's demo and a statement from Intel's engineer, who talked about the fact that CPUs could soon be strong enough so that you wouldn’t need a GPU in the future. While Intel told us later on that the engineer’s remarks did not reflect the company’s opinion, the statement made waves at Nvidia and prompted the company to create a physics demo with 65,000 simulated particles.

While Intel's Nehalem demo had 50,000-60,000 particles and ran at 15-20 fps (without a GPU), the particle demo on a GeForce 9800 card resulted in 300 fps. If the very likely event that Nvidia’s next-gen parts (G100: GT100/200) will double their shader units, this number could top 600 fps, meaning that Nehalem at 2.53 GHz is lagging 20-40x behind 2006/2007/2008 high-end GPU hardware. However, you can’t ignore the fact that Nehalem in fact can run physics.
This leads me to believe that they either copied it or had more than 1 person writing the article.

I mean they have been around quite a long time, doesn't seam like they could have avoided bankruptcy that long.

It was only around for 6 years and was only actually selling stuff for a fraction of that time

Now lets hope once this is done Crytek will patch Crysis for support.

Who would have thought it was a mistake for Crysis to not support Physix?

If Crysis had AGEIA would have had it in the bag.
