    On top of that here is what Charlie had to say in one of his posts at Aces forum:

    It's very vague, but at least we should have a surprise (good or bad :twisted:)

    Question: Does chip design/debug/validation/verification time scale with die size or what? :?:

    I'm thinking I should sell my GTX 285 now while it's still worth something and grab some cheapo card to hold me over until ATi shows their high-end DX11 card.

    WTF???
    Is he implying that not only was RV670 launched with A11 silicon but RV770 and RV840/870 will be aswell?

    If true that is ridiculously awesome, from an engineering standpoint, and I think that just proves the point eveN more that they guessed the right way of doing things when trying to rebound after the R600 launch.

    If you estimate based on PEG length, the card looks around 10.5" long.
    Not really a usual size for 256-bit single-gpu AMD card...

    It's probably lower, they mention it's slightly longer than 2900XT, which like most AMD's recent cards is 22cm (~8.7 inches), while the competition + their X2 cards are 27cm (~10.6 inches)
    So I'd put my bet on under 24cm, maybe 9 inches sharp aka just under 23cm?

    Isn't 2900xt 9.5in long? Same as 4870?
    I would put my money on 10in for this RV870.

    So this almost seems to confirm the 181mm2 chip and the card we saw at Computex was in fact RV830/840.

    So the real question is... what is under the cooler? A MCM design or some other unknown 240-300mm2 chip?

    For what it's worth, the ratio of card length to PEG sticky-out bits (front of square block which has no electrical connections, to point of hook) is about 2.17 for HD2900XT and HD4870. For HD4870X2 it's about 2.4. For this card it seems to be 2.4+

    The single-card GTX295 is 2.4 and GTX280 is 2.35.

    Anyone else get the same kind of ratios? I suppose I shoulda measured from bracket to the hook for the shorter measure, to be more precise, but can't be bothered now...

    2900XT isn't 9.5 inches long, and neither is 4870, they're a bit over 8.5 inches.

    HD4870X2: 270mm http://ixbtlabs.com/articles3/video/rv770-3-part1-p3.html
    HD4870: 220mm http://ixbtlabs.com/articles3/video/rv770-2-part1-p1.html
    HD2900XT: 220mm http://ixbtlabs.com/articles2/video/r600-part2.html

    220mm = 8.66141 inches
    270mm = 10.6299 inches

    10 inches would be 254mm, and going by the looks of older cards, they seem to put in few extra mm's if needed to make it even numbers on metric scale, so 250mm or lower would be my bet

    Not sure where they are getting those measurements from...
    Just got home from work and measured my 4850 and it is 9.25in.

    Most the numbers I've seen have...

    4870 ~ 9.5 in/24 cm
    4850 ~ 9.25 in/23.5 cm

    For comparison

    8800 GTX ~ 11 in/28 cm
    GTX 280 ~ 10.5in/26.7 cm

    Regards,
    SB

    Longer then the current cards for sure. Shorter then current X2 cards. But we have not seen a non 256 Bit x2 card yet.

    I think 3870x2 was a 192 bit X2 card.

    wait wat

    I think you're confusing it with the RV670 diesize, which was around 190mm^2, but the chip itself had a 256-bit (512b internal) ring bus.

    So, will "RV870" be a Dual-core GPU or not? What do u think?
