    RV770 won’t do FSAA through Shader!

    http://www.fudzilla.com/index.php?op...7625&Itemid=34

    Pre-Computex 08: They will do it the right way

    We've learned that RV770XT and Pro won't do Full Scene Anti Aliasing via Shaders. Developers hated it but RV670's design flaw was responsible for it.


    RV770XT and PRO will end up significantly faster, especially with FSAA compared to RV670 generation. The numbers should be higher than you usually see from generation to generation, but we don’t know more details about it at press time.

    RV670 was improved and fixed R600, or should we say R600 done right, whereas RV770 is an improvement of the stuff that ATI has implemented.

    So then you can't get 24x edge detect AA, that's a shame.

    HDMI 8 channel Audio

    http://www.fudzilla.com/index.php?op...=7626&Itemid=1

    "We have just confirmed that ATI HD4800 series powered by RV770 chips will support 7.1 surround sound audio with AC3 and DTS and the new cards will be able to drive HD video and 8 channel audio via single HDMI cable.


    The RV770 based cards will use DVI-I to HDMI adaptor and the reference design of RV770XT and PRO includes two DVI outs. At same time RV770 / HD 4800 generation won’t have any issues supporting DisplayPort but this is a matter of a partner choice as DisplayPort is still not that important or accepted.

    The possibility is there and display manufactures do plan to embrace this new connector.

    The new RV770 chip also supports xyYCC color:end quote

    The new logos are better than the old ones. I don't like having to use DVI adapters since I can't get 75 hz on my monitor if I do that...

    Haha. OK. AA is not done in the shaders. Then where? In the ROPs? In its 16 ROPs?

    Same here. would be better with a separate (real) HDMI port.

    Um... yeah. Where else do you think it would be done?

    ROPs are not a bottleneck for RV670, and 16 ROPS @ 850MHz should be enough from what I see. It would give RV770XT only 18% less pixel power than the GTX 260. Even though it has 28 ROPS they are only clocked at 575MHz.

    If only I could step-up to HD 4870 with the eVGA Step-up program. HD 4870 is sounding better and better everyday, and at $300 versus $450 for the GTX 260.

    go 4870 \o/

    its my #1 choice for my new build atm, Unless the GTX 260 is priced very well, or a lot lot better

    hey everyone, by what percent is a 9800gtx faster than a 3870? and can u use that number to predict benches?
    well, no, u cant, cause there is no really fixed percent it is faster than it. so u guys are reading into the percent thing a little too much.

    But the fact remains that HD4870 > 9800, RV770 > GT200 price-wise, and R700 > GT200 performance-wise, and probably price-wise aswell.

    Is that a fact, all of a sudden?

    I mean, everyone is jumping the gun over a bunch of wildly differing powerpoint slides..

    At least wait a couple of days for Computex, where we'll see both card series in action..

    AA not in the shaders may sound good if there were any proper location to do it instead. I just can't see it. Wait and see...

    I doubt they would do it unless it was that big of an issue - increased shader count + speed + supposed double clocks/sec of ROPS would be more than enough. Besides, are they really going to remove 24x aa and edge detect?

    Naw, was just a spiky comment. But then again, it seems possible. At least I don't mind if X beats Y by +/- 5 % difference, some of it goes to the margin of error, alot of it goes to the drivers, and in some cases there are just too many factors which count to be able to give accurate readings of the performance. Well, I say that pricing(and PR!) is something which is going to declare the winner, IMO.

    maybe they do the AA up to 8x in RBEs and the shaders allow to go up to 32x with somes filters.

    & maybe it's always shaders and fudzilla lie

    Anyway Narrow-tent, Wide-tent and Edge-detect all produce blurry images for me. So nothing to worry about if they are disabled.

    I'm thinking Fud and/or his source misunderstood something.
    Why do I think they caught wind of the z being upped to 4x and they assume that AA is back on the ROPs.

    Box MSAA on ROPs, tent/edge detect on shaders I guess.
    But it doesn't matter I guess, considering both ways will be samely fast.

    And it's getting very ridiculous that the specs haven't leaked out a bit.

    Well, 32 TMU's on a single core is the first time ATI has ever done that. Everything from ATI up till now were no more than 16 TMU's. Nvidia already upped it to 24 with their 7800 cards. X1800, X1900XTX, and even the HD 2900 and 3800 cards only had 16. Nvidia's 8800GTX upped it again to 32 (64 texture filtering processors).

    I do not think the ROP would be too limiting, as evidenced by the 9800GTX cards. Thanks to excellent overclockability, those cards can equal the 8800GTX cards with 32 ROP's in nearly every game with FSAA except at 2560x1600 resolution which is hardly used by anyone. Remember, the 9800GTX's are also severely limited by 256-bit memory bandwidth (and also only 512MB buffer).

    We know for sure that the RV770XT will have nearly twice the bandwidth with GDDR5 (and it looks like there will be a 1GB version widely available). I think ATI just wanted to keep the die size and power consumption as small as possible and the first thing to ignore was the ROP's. The X2 version will have a total of 32 ROP's anyways, since that is what ATI is really betting its horses on.

    The question is: Will the R700 (4870 X2) actually beat the GTX 280 in overall games at 1920x1200 with 4xAA?

    I've heard some say that it will no longer be Crossfire scaling but a "hardware infusion" of both chips so that it can act like a single core processor altogether. But now I see from the heatsink design that it will still be two separate chips a few inches apart from each other, so it is probably still going to be nothing more than what the Crossfire drivers can do.
