Now the question is, how many rv770 needed for this ruby demo. 2, 3 or 4? Anyway it will cost much less.
Which one looks better? Definitely Ruby.
OMG do people read others' posts. Look at the few ones above yours, they have said it all. Ruby one looks better because they made it to look better. This one is an I-N-TE-R-A-C-T-I-V-E T-E-C-H-N-O-L-O-G-Y D-E-M-O
. It's meant to show that 1920x1200 @ 30 fps can be done. Especially in ray-tracing textures don't matter as much as in rasterizers performance wise and same happens with many effects. This demo is lacking them because they were out of their scope, but they could add them with any significant performance penalty.
About the hardware, we don't know the one used by Ati, but those Quadros are nothing else than GTX cards. So in reality they just used 4 GTX280. Sure, they are more expensive than RV770 derivatives but not by that much and they are really doing a lot more work than on the Ruby demo.
And again, as many many many others have said it doesn't matter how it looks. What looks better real games or 3Dmark?
Hint: 3Dmark is not interactive.
And about tesselation. Yeah they used tesselation and that is good, as it increases the detail level with minimal performnce penalty (compared to actual polyfons), but tesselation on the other hand very hardly adds details (and also very hardly can be animated), it just makes things smoother. And that's a very different thing. Nvidia demo demostrates that they can use 2 million of actual polygons that can be transformed and animated. The Ruby demo even if it had 10 million polys after the tesselation was applied doesn't mean anything special, as the 2 ones of the Nvidia demo are far more interesting from a real performance point of view.
