All those scenes have been done in 3D rendering packages by people who probably don't own an NV30. You can find where the originals at http://www.exluna.com/products/gallery.html. nVidia just brought the rights to use them, and (probably) rendered them on an NV30. I could render the same scenes on a system with a Riva TNT and they would look just as good.

The main question is, how long does it take the NV30 to render these pictures. If it could render a scene like that in 1/30 of a second then you can claim its real time. But we have heard nothing about the render times of these pictures.

Until we get more official press releases from nVIDIA, I wouldn't take these as gospel examples of what the NV30 can do in real time. On the other hand, with the new pixel shaders on the NV30, I wouldn't be suprised. nV has also been working with SGI on a good way of doing real-time "soft" shadows for some time. The most complex picture is the bike, but does it really have much more detail than a frame from the Wolfman Demo?

If NV30 is not as fast as the 9700 but offers better image quality then that's the card I'm going to purchase.
This is what's probably going to seperate these two cards, both will of course be much faster than what's currently available, which one has the best features and image quality will "win" this round IMO.

There is nothing to worry about. R300 will be in store around September. NV30 little later but i bet this year.
Thats actually a fair comparison, because like with the 8500, FSAA won't actually work on R300 until weeks after its release anyway. Yeah, yeah, I know... ATI drivers don't suck anymore... but they say that with every ATI product release.

Have you used a Radeon within the past 6 months?

>Realtime is considered 30fps


Ok... Then if the question is "Can this be rendered at 30 fps?", I think we'll just have to wait and see...

For those willing to have the answer sooner, a lot of things are public already; probably enough to find the answer, but you'll have to dig by yourself, which can take some work (and an understanding of those things)...

While I'm there, just a quick comment:

Exluna's sell to NVidia... is imho a bright move, which just says how much they know already that the graphic hardware will be at risk of becoming ‘commoditized’ in the future - because it's 'merely' big arrays of transistors, and it's getting fast (a few years?) to the point where further improvements might be regarded as "details" by the general public. I also certainly see it as an acknowledgment of ATI's recent competitive lead... Anyway, the battle will expand to the software area, and they're the first graphic chips designer getting there it seems...

About the 256 bit bus (quite a technical achievment! Kudos ATI!), it seems Samsung might well supply its latest DDR II 1 GHz for the high-end nv30 cards... And that would mean a nice bandwidth to play with...

Not me and I bought one last October or November (can't remember the exact month).

That was actually a comment someone made in some newsgroup. Then I quoted it over at 3DGPU forums as an example of what people would say to defend the competition (or in the case of that guy, to criticize NVIDIA). That was in 2000 Spring. So....it is actually more than two years ago.

So 1 Ghz mem will compensate for the lack of 256 bit bus?

I'm not too sure, but according to my info it would come in chips of 128 megabits with a bandwidth of 4 GB/s.

That would mean 16 MB per chip, so for, let's say 128 MB, you need 128/16 = 8 chips, and 8 * 4 GB/s = a lot of bandwidth!

Take this with a pintch of salt, it's nothing but speculation. Even if I believe Nvidia and samsung have signed an agreement in which Samsung agreed to supply volume quantities of their memory (which precise model, I do not know).

Some people state that these pic were rendered with a nv30 using a cg plug-in for Exluna's rendering software.

I find that very difficult to believe, if nVidia had access to all these scenes then why not render them with a different angle or camera view? I mean, is it that difficult to change the camera angle in 3dsMAX? also, it should take less than a second to render, right?

I don't think that nVidia needs this kind of hoaxes, the nv30 is sure to rock the 3d world all over again.
