ATI RV770 'On Par' With Expectations
With the launch of the GeForce 9 series getting closer and closer, AMD is hard pressed to find something to keep themselves competitive. While the RV670 and R680 are regaining some much needed market share, they will both pale when the GeForce 9 series is released to the public. Thankfully, AMD is not going down without a fight. About the same time as the GeForce 9 series is released, AMD is releasing a little something called the RV770. At this point, it appears that the RV770 is about 50% faster than the current HD3870, which is certainly respectable. How this compares to the GeForce 9 series is still a mystery. The release of CrossFire X technology ought to really help benchmark numbers, assuming AMD can make buying four AMD GPUs cost about as much as two from NVIDIA.

the r700 is the high end chip...eventually made up of a couple of r770s...i have heard multiple..with a possibility of upto four...so in actuallitythe r700 will be the high end while the 770 the low end or core component of the 700.
ati' see multiple gpus as a future so as long as the 3870x2 does well the r700 will continue to grow...and we are all waiting on drivers.
Still, though, dual core GPU . . . and if ATI decide to make a dual R770/R700 GPU PCB - that's 4 cores on one card
Rumor has it the R770 and R700 will also support GDDR5, and we all know how ATI loves to jump on new tech like that
brace yourselves . . . the GPU wars are about to become extremelly interesting again :toast:

I think ATI can make it Large Again! (Rise from the Ashes:))
Sorry not ATI, AMD!
translation,
may your mouth be filled with sweets and sugar ..... lol
wub be nice to see the red team right there on the horizon =P
Single chip, 45nm. Use their new FABs for GPU as well as CPU
Put two on a card and you have single-slot, quad crossfire and a pair of PPUs.
That would seriously rock.
It's like to reach 1.00 you can use two 0.50 or four 0.25. a 0.25 is weaker than 0.50, isn't it? The idea of using many weaker units to make a strong unit is worse than fewer units to reach the same? So to attain a certain performance would you take four ATI cards or two NVidia when a lot more things go against the ATI setup like the price of the platform, power and cooling?
Jab do balwan toh chaar ka kya kaam? - zOaib can translate that.
If they could do it in quad on a single chip, even better.
So dont everyone get worried Im sure there will be a R770 released as well
please lets be clear, if i cay "japs" that is not an insult, i love the japs, great people!!!
well their way of looking at tech advancement is why they can consistnatly bring out stuff that drives other countrys products off the market.
unlike americans and many western based culturs the japs dont go for the big score/touchdown/home run every time, they are happy hitting singles all day and just burrying you with runs(baseball anniligy) American companys alwase go for the big advancement, where as japs and some other culruts will just make small improvements and bring them out more regularly, eventuly they BURRY you in small improvements AND they by using this method they have managed to keep production costs VERY LOW, so dont go by the "home runs are alwase better" assumption,
your annaligy would lead one to belive it would be better if amd and intel had stuck with making singel core chips and had just made them drastickly more powerfull and higher clocked, when thats just not true, for SMP/threded apps its better to have more cpu's/cores to spred the load over, and slowly but surely the world is headed threded!!!!
and it really dosnt matter how you get there if the results back it up, if amd uses 45nm vs nvidias 55 and 65nm chips then amd will almost certenly have the more energy efficent chip, if u tag 2 dual core versions of that on 1 pcb you have quadfire in 1 card!!!
as to the guy who said he wanted to see a PPU onboard as well, if game developters get off their ass they could do PPU work on the x1k cards, but they havent bothered, mostly because intel bought havoc and havoc was the main company working on gpu as ppu emplimentations.
a "True" ppu is just a very powerfull math unit, guess what, thats also what a modern shader based GPU is, an x1300pro is ruffly equivlant to a first gen agena ppu card, an x1300xt kills it, if you look at the HD seirse the 2400 kills agena's current products for raw prosessing power, its just that nobodys bothered emplimenting it YET.
we need somebody like MS to step in and say "heres a new standred for phsyics thru a common API, make your drivers fit the API calls and you cans upport phsyics"
^Look at what an unoptimised game can do. So, it's important to have stronger units. Let's face it, the G92 is a superior core to the R670, we've seen enough people attesting that, just that when in an SLI array, it slightly falters but that's the platform to blame, not the cards. In a 32-lane SLI chipset like the NForce 590 SLI or the 680i SLI, the northbridge and southbridge give out 16 lanes each to a card while in a 32 lane CrossFire compliant chipset like the AMD 790 FX or the Intel X38, the northbridge supplies all the 32 lanes. So well, a SLI of two G92 based cards falters slightly to a Crossfire of two R670 but if NVidia works well with its internal SLI on the 9800 GX2, we'll have a card waay more powerful than a HD 3870 X2, reason: the use of a powerful unit core. And supposing the 9800 GX2 does end up facing an unoptimised game like the HD3870 X2, it will perform better due to its stronger unit core.
