Created in a dark, futuristic setting, the demo utilized a host of advanced rendering techniques that smoothly tessellated and morphed facial features, created realistic street scenes using point light reflections, and replicated the work of the best movie directors through the use of fine-tuned out of focus bokeh filters. The only downside was that it took three GeForce GTX 580s to run the demo in real-time.

Today GDC 2012 is upon us, and once again Epic has shown the Samaritan demo, but this time with a twist - instead of three GeForce GTX 580s, the demo was shown running on a single next generation NVIDIA graphics card.

If you'd like to learn more about Samaritan, Unreal Engine 3, or any other aspect of the demo, check out our in-depth Samaritan deep dive from May 2011.

For more info on our next-generation Kepler graphics card, stay tuned to GeForce.com.
Looks like the March 12th date just got some more substance? I don't buy that it's running identical settings/performance as 3x GTX 580 SLI, though.

And this is nice to see Samaritan running only on one kepler.
But would the kepler been able to run the demo smoothly if it wouldn't use fxaa? that is the question. but still 580x3 4xMSAA vs kepler FXAA is impressive
Haha

, and I agree with your assessment.

I am not a fan of FXAA at all, i would rather have no AA than FXAA. Thats still impressive though, cant wait to SLI some 680's or 780's

I agree. To both things.

If I had to guess I would say gk110 considering other posts here on the news section say the gk104, which is called the gtx 680, is about the same as a 7970...

If it is indeed the one being released soon, then 3x GTX 580 vs 1x GTX 680 even with the 4x MSAA vs FXAA is still a very large feat. Sadly, this means nothing unless they say this was a GK104 or GK110.

I think people are taking this the wrong way. The 3 way gtx 580 obviously has more power then a next gen nvidia card. What this demo shows is that a single kepler can with some shortcuts and optimizations, produce graphical fidelity that is very similar to the original Samaritan demo. Another thing that is not shown is FPS. We can assume that the original Samaritan ran in the 50-60 FPS with 3 gtx 580. From a youtube video its impossible to know how much FPS the kepler was able to manage. Maybe it managed the same 50-60 but I think its much more likely that is slower perhaps in the 30-45 FPS range.

Of Course this is just speculation on my part

Quite a bit.

It took three GTX 580's for 60 FPS. It's probably running at 30 FPS on one Kepler.

Its pretty easy to tell from the video it's not 30FPS. Looks like 50-60FPS to me, but I doubt it's the GK104.

Hate to brake it to you buddy but youtube videos only do 30 FPS max so even if the demo was run @ full 60 FPS you would/should not be able to see it in the video. So unless there is a version with the FPS displayed we are left guessing.

If it is, Nvidia just made the best microarchitecture ever known to mankind.
They did such a leap with G80 after the 7900. It's not out of the realms of possibility they did it again.

Why is everyone assuming that 3 x GTX 580 in the Samaritan demo is 3 times the power of one GTX 580? Unless anyone has evidence then it's more reasonable to assume much less scaling which would make a single kepler much more possible especially when you consider how much of a performance hit MSAA causes in a DX11 game. I came to this thread expecting to have to explain people to take this with a grain of salt but it appears the opposite has been forced from me.

What's wrong with FXAA? Gah...I thought it was confusing with MSAA and QSAA and ZSAA (jk) what is the difference?

And yeah....3 GTX580s in SLI isn't 3x the power of a single GTX580 except in consumption.

Gah...all this nvidia talk has me worried that these cards aren't going to be good since this is sounding like...you know what I'll not mention the CPU codename that creates flame wars.
