    Ditching dual-link DVI should have been ridiculous on its face, as I thought it was a part of AVIVO. Yeah, I thought if they did ditch it, it would be a byproduct of internalizing XFire. Much ado.

    I have a hard time believing RV570 is as fast as R580, though, without seeing the 256MB as a hugely limiting factor. They should've tried 19x12 or something, and with 1x or 2x AA, to minimise potential memory limitations, but this /is/ just a preview.

    The drop in power draw is awesome, though. Surprisingly high, actually.

    Edit: Yeah, geo, I meant a surprisingly high drop, not surprisingly high draw. 54W seems crazy large for just a die change. Then again, the fact that it seems crazy just highlights my ignorance, as apparently the current ("quad"-disabled R580) GT already draws 40W less than the XT 256. That puts any savings from the process drop in the 10-15W range, if DT's overall system draw #s are comparable to TR's. Not bad, but not monumental.

    And there's something wrong with DT's #s, as TR shows the XT 256 to hit 5.7k in 3DM06, not a mere 5k (which is closer to the current GT's score). If they're using review drivers, maybe those are (severely!) impairing the XT 256.

    Those power draw numbers they showed appeared to only make sense as system power draw rather than just vid card draw, even tho not labelled that way. If that is correct, then a 54W drop off just based on the vid card is a yowza kind of number, as from a percentage pov a good bit of the overall system number is static.

    maybe the performance is because RV570 is 12-1-3-2? :eek:

    The RV560 numbers are nothing to sniff at, either! 805 points! For only 22.4GB/s bandwidth that's pretty nice (as compared to X1900GT's 38GB/s).

    It's interesting. From the above Digit-Life link:

    3DM06 1600x1200 4xAA 16xAF
    X1900XT 256MB 625/1450 - 1105
    X1950Pro 256MB 580/1400 - 985

    3DM06 1600x1200
    X1900XT 256MB 625/1450 - 1815
    x1950Pro 256MB 580/1400 - 1610

    Roughly in line with clock speeds.

    Maybe for 7900 GS, yes.
    But what it NV decides to kill that SKU, and lower the 7950 GT down to that price-point ?
    G73-B1 is coming, and since it's 80nm also, they could crank the speed of that part to compensate for the 7900 GS, and let 7950 GT take its place.
    It's not like it can't be done, look at the 7900 GTO vs GTX. It even manages to maintain the same core clock and cooling solution as the high-end.

    In that sense, is there any room for OC in those RV570's with the standard cooler ?

    Yeah, I don't get why RV570 is so close to the XT 256 in 3DM06 or CoD2, both with and without AA. I mean, CoD2 can't be bandwidth-limited, b/c even the X1950XT barely distances itself from the X1900XT. It's not ROPs or TMUs and probably not pixel shaders (see X1800XT). Maybe a vertex limitation? Must be the demo itself. As for 3DM06, I can't figure out how RV570 distances itself so handily from the X1900 GT, and why it's only 10% shy of the XT 256. Sure, the XT's hobbled by RAM, but is that really it? It looks like the difference is more in line with oure core clocks than anything else. Otherwise, RV570's spotting R580 33% more ROPs, texture units, and pixel shaders. Dunno about vertex shaders, but I thought '05 was setup limited, not '06. It's veird!

    Maybe the A64 is a limiting factor, but DT was using a C2D when they got 5k out of their XT. Xbit Labs got 5k from an XT 256 but with an A64. TR and now FS both pulled 5700 with the same C2D with which DT manages just 5k. Friggin' lack of standards. :)

    Aaanyway, the XT more properly (well, at least more in line with the theoretical differences) distances itself in everything else D-L benches, even 3DM05. Something just wacky with 3DM06 and CoD2, I guess, and probably more to do with the drivers in the first case and the demo (.exe) in the second.

    Edit: Welcome to the forums, Arnold, and thanks for the link.

    The X1950Pro is listed in some shops since September 23rd; Xada and Fortknox belong together. Such offers are normal: pre-order, pay and wait. You will get your X1950Pro, when it coasts, what you have paid, and it doesn't matter, that X1950Pro is available.

    I know, that the RV5x0 graphics cards are not available until October 17th (or later). What I have meant, is that is senseless to pre-order X1950Pro in these german shops.
    Example: You pre-order a X1950Pro today and pay 190,- Euro. Next tuesday the new ATi video cards are available in these shops, but they cost 200 € - 10 Euro more. Ergo: You will get your pre-ordered X1950Pro, when it costs 190,-.

    Die Size of RV570 is less than 238mm^2
