Nvidia chips to make tardy debut

Yeah, but he’s not saying 'free AA', he’s saying 'bandwidth free AA'. Like the AA on the Kyro. It costs fillrate to activate and transistors to implement, but it doesn't cost bandwidth.
(Ok, it's possible the smaller tilesize would cost bandwidth, but they could have made one that used the same tilesize for AA and non AA, so it ‘bandwidth free AA’ could be done.)

Wow you mean something really origional like... SuperSample AA...
What makes you think that if you can truly get bandwidth free Supersampling, that Multisampling then would influence bandwidth in any way?
It was just an example anyway. By the way wasn´t Supersampling until recently the "superior" method to antialias?

It still is IMO. Multisampling is cheap/cheat AA of course that is MO. SSAA does far more work yet does not get recognized with benchmarks...... So I guess until it does, MSAA is the bar. Maybe that means that nvidia has to do SSAA successfully before SSAA gets recognized as the measure? (that is a pretty poor indictment of the industry BTW.)

Multisampling is a more efficient way of doing AA: You don't need to waste time supersampling the textures as better filtering algorithms do a better job anyway. As shader programs get more complex, MSAA will become more important.Sabastian said:
That was one of the big problems comparing AA on the Radeon 8500 vs the GeForce 4.

My point was that you are making a tradeoff someplace. I'd prefer if people gave the tradeoffs being made when talking about something like "bandwidth free AA". OTOH, I wouldn't call the kyro's method bandwidth free because you take a bandwidth hit going through the geometry more than once. Of course, you take this hit with or without AA, but it is still a tradeoff.Thowllly said:
There's a good example of a tradeoff, thanks
Sadly enough yes. God knows how often it has been pointed out.
Dumb question: do any of the PR people even bother trying to reach reviewers about issues like that? I do not mean to influence them in any way, just attempting to show them what is and what not....
As far as Multisampling goes I like it myself a lot. MS algorithms are improving and will even more. What I would like to see though is better texture filtering algorithms (is it even possible to deal with texture aliasing f.e. via alternative anisotropic algorithms?).

What are the chances that Nvidia is leaking all these limited availabilty rumors in an attempt to make Ati relax a little bit. I know that it is highly unlikely, but it isn't bad bad idea; however it might backfire and send customers flocking to Ati for early Christmas shopping.
A healthy restructuring of the market in the immediate future can be for the biggest benefit for us consumers. With the release of the mainstream R300 line, NV will be forced even more to press their prices for NV25/8´s down, in order to stay competitive.
If that trend continues then ever better than Ti4200/9500 level price/performance rations might become the norm in the foreseable future.
Albeit I´d prefer to see more agressive competition from other vendors too, the more the two top dogs stand on equal or almost equal grounds in terms of market shares the better for all of us.
I'm not really going to comment much on this item since I think its as much as we knew already. However, given what we already know about NV30 I did find this statement a little amusing:

I'll stick by those now infamous words from Kristof....
"Nothing is for free in 3D" ?

Book you're looking for is "The Moon Is a Harsh Mistress". It's bloody fantastic, and despite being written decades ago still does not feel old. Maybe because it doesn't deal that much with technology, except in one notable exception (and even that one does not feel "old").

Yep - that's one of his better books. Later in his life he went a bit bonkers, though (he had a stroke, I believe) and some of his books were peculiar to say the least.
One I read when I was a kid many years ago was "Tunnel in the Sky" and that one really caught my imagination. I also enjoyed "Starship Troopers" myself, and was disappointed with the recent Movie - where was the powered armour!
