So, do we know anything about RV670 yet?

    I'll be damned if Joe doesn't buy the GT with a big chart on the box saying "30% faster than RV670" ;)

    The Inquirer reckons RV670 will have a low-noise cooler. (There are some pictures at the linq).

    http://www.theinquirer.net/gb/inquirer/news/2007/11/08/hd3850-3870-finally-quiet

    I had been under the impression that 3870 was also single-slot, but maybe not.

    "3870 X2". Well, that seems to settle that.

    Sooo, "775MHz+" - still undecided, or something related to the new "selfadjusting clockrate"?

    Thank you! :cool:

    From the slides - in 3DMark the 3870 is 2% faster than 2900XT. Which brings us back to question: for what was 512bit external interface of 2900XT actually intended for? Uber-resolution gaming with insane amounts of AA?

    Edit: I don't really understand why clockrate 775MHz makes sense for 3870. 780Mhz would probably still be about 35dBA, but "500+ GFLOPS". :???:

    If the claims are correct and clock-for-clock performance is identical to 2900XT then we can predict: 800MHz is 8% faster, 825MHz is 11% faster. At least it isn't slower, as I feared! :cool:

    Two 3850's in Crossfire should work just fine with the aging RD580 chipset right? That would be a sweet upgrade and should last a while. Still on 939 with an X1900XT here. :???:

    Thanks for the slides.

    unfortunately no word on performance improvements with AA. 3DMark is relatively meaningless.

    At least that name will make sense, even if the X remains.

    Those CrossFire scores aren't much to write home about, and the lack of AA in the CoJ test doesn't bode well. AFR coming undone?

    Will the drivers get substantially better? Will AMD delay X2 until the driver is decent?

    The funny part is Joe will have no clue what RV670 is .. :lol::lol:

    True. The only thing I found interesting in those slides are X2 and the die size of RV670. Gosh, AMD have a 70% die size advantage this round.

    Bear in mind that the 1Gb 2900XTs(I know, fairly rare), at least Diamond's ones, are already at 825 GPU-clock(as per Diamond's site). So the 775Mhz clock is even less impressive, IMHO.

    When we first heard of the 775MHz clock, there were two possible explanations. To keep the stock cooler single-slot or to hit lower price levels. I was in the latter category, now it looks to be the case.

    It would be, except F@H does not yet support anything beyond RV560/RV570/R80.

    It's half the price and half the power consumption, with less noise and far less heat. How is that anything but impressive? Sure, it's not twice the speed, but it's just a refresh.

    With proper cooling I wonder how well the 3870 will scale in performance when oc'd?

    I'd consider 10% normal, 15% good. I'd expect a whole lot more, of course, but these kind of expectations are often called dreams. :cool:

    Let's discover a new concept:IMHO, it's unimpressive. I should've pointed that out. Because I really dont care all that much about power consumption, noise&heat(watercooling is my good friend). I'm more into performance types of things...or features-the RV670 brings neither(DX10.1 solving Global Illumination-yeah, sure, now why didn't we figure out ages ago that it was that simple:D). Probably there exists a niche for those like myself.

    It's also unimpressive in terms of the about a billion five hundred million posts:OMG, it's going to OWNORRZ, it is ATi's comeback etc. Call me odd, but fanboysm pisses me off considerably(from either side of the fence), and the fact that it's simply a middle ended not excessively sexy refresh gives me a limited ammount of satisfaction. I'd still like to get my grubby mitts on a pair of 1Gb 2900XTs from Diamond, just for shits and giggles...hmm, time to sell the 512MB ones.

    The "giggles" part I can understand, but do Diamond's 2900XT cards really act as a laxative? :???:

    Or maybe you need 2 of HD3870 1GB DDR4 cards :cool:

    Just only a week left for the RV670 parts and the INQ added more to it...
