can do aa in shaders probably if they bothered to try

Read the NH article.

So one website says a confidential source has told them yadda yadda yadda, another website(Fudzilla) has mentioned final clocks, so NH divulges information they were told not to share? I should take this as fact because? :rolleyes: If these are true then great but anyone can fake a document :down:

why would it hurt aa performance that much? The 9800gtx has 16 rops and still outperforms the 8800ultra in most cases except for ultra high resolutions and extreme detail in which case you won't be able to play the game anyways. Besides AA is handled by the shaders with the r600 design so it shouldn't really matter

He speaks sense. But I think we were just hoping for more extreme increases ^^ We won't know until we see the hard numbers i guess how this will pan out :yepp:

ati dont care, tehy make the cards to directX and ogl specs so just becouse devs are instructed not to by some pople dont mean that ati needs to change how they do things, they sell more cards to labs and industrial apps than gamers

in dx10 the same buffer is used for the pre and post render for AA, so its not needed to have special hardware models for it, unless u use AA from dx9 or ogl 1.5

well im just saying. why upgrade so much of the other parts only to keep one of the weakest points there. why not cut shadders for more rops if they wanted to keep the power envelope. Look at R600 it had way to much bandwidth and lots of shadder power but only 16 rops and of course while it not the only reason it was a major factor in it's "lackluster" performance. and RV670 kept the same number of rops and now RV770??? it's knid of a let down to see. hopefully RV870 (or whatever it will be called) will have at least double. also the reason AMD cards AA performance is not as good if because they don't use the ROP's, if they had more to use then the could very possibly move back and thus the hit for AA would not be as much. because the way it stands is the 3870 can pull playable frames normally but turn on AA and it can be right on the edge or comfortable frame rates. and i don't want to buy a brand new "high end" "upper midrange" and have it not be able to do AA and max out all of my games (not crysis) on a reasonable resolution.

i really hope AMD can pull up and have a good performing and well priced product but by the looks of it GT200 will be a hard competitor to beat. BUT if they price the 4870 well it will be a hit.

If that's why their holding back then they are idiots!! Maybe they like being raped by nvidia though.

They're idiots if they let it hold them back - but unless you're telling us you know their architecture better than they do, I can't say thats for certain that is whats holding them back. In fact, their 16TMU's seem to have been the weaker point, which will be doubled. Also, keep in mind 16 raw ROPS doesn't mean they didn't double their operations per second... there's a lot of optimizations they can do you won't notice until real world tests are done.

So SINGLEDIE and 256BIT bus. Now can the dualcore/MCM etc superhype fanboys rest? Or will it already start again with HD5xxx having blablabla :/

Are you drunk?
What does HD4870 have to do with R700?

Not at all.
I was simply asking a few questions, which you have yet to answer.

There is more to RV770 than what meets the eye, or ear.

If so, 4850 crossfire looks very nice

Not happening; the cards would have to be connected with a super fast interconnect, as fast as memory - Crossfire bridge nor PCI-E don't have that kind of bandwidth.

If perkam's price predictions are close, then I'm crying, haha, hopefully there'll be a nice price war to push things down a little between them and Nvidia.

HD 4870 1GB GDDR5 - most expensive and most useless. :( Anyway, I already have a HD 3870 since February - I'm would feel crazy and stupid to get an alternative after 3 months... who knows maybe by October they'll release HD 5870... :shakes:

ATi/nVidia stop messing with our brains, one generation per year should be more then enough. :down:

Nor did you. People claim miracle chips each time only to wakeup to a harsh reality on release day.

If you think AMD is havign a technological giant leap in their sleeves instead of basicly doign what they did for the last 15years+. Then its up to you to prove it. But this ends with the rest of the GTX killers and 50% faster clock for clock than Core 2 Barcelonas. In a wishdream that never materialized.

The Rops and Bus look like they are really going to hurt this card badly in terms of actual real world performance, especially when you up the AA at high res.

Its probably going to be an absolute monster of a 3DMark benching card though, just a shame that 99% of people couldnt give a crap about that though.

Sry to disappoint u, but this is fake and not the final specs. If u dont believe me, just wait a few weeks.

FAKE

They'll have a die shrink and slight update in around 6 months. Yes, a 6 month product lifetime. :rolleyes:

Oh well, I guess they feel like they need to make up for the 8800GTX/Ultra being the single-chip king for nearly a year and a half. :p:

If only game developers would follow their steps. Apart from silly games like Crysis every other game is a console port that runs perfectly with a single 9600GT..

i dont think the things your are suggesting...

Do we think core clock/shader speeds on the RV770 will be BIOS locked like the RV670?

^Ummm... RV670 is not bios locked.

No the lack of texture power was the biggest blow imo, this time around it'll have more than enough shader power for aa and hopefully enough TMUs (I personally would have liked to see the 64 g92 has, but that's just me), but only time will tell.
