    I recall a vague form of consensus that mobile R520 was not going to happen. Dave, will you take the ceremonial first stab at Fudo? :lol:

    O Canada!
    I was at the same event that Fudo was at that prompted him to talk about this. All I can say is that there was nothing to disuade me from my prior suspicions about what M58 would be / now is.

    And M58 now is presumably Mobility X1900 :?:

    Edit: just what event are we talking about?

    Damn, you guys beat me to it. Tho Kemosabe handled it more gracefully than I would have. :lol:

    This is just the tip of the iceberg...

    Who's going to CES? ;)

    Hm... according to a friend of mine, M58 is the mobile R520, and there is an M68 coming in Q3 06 which will have 36 shader pipelines on 80nm. M78 will be on 65nm in Q1 07.

    Perhaps more like xenos less like r520.

    Needs more like R580/ RV530.

    Dave is still convinced there will be no mobile R520-based ASIC. That should lead us to conclude that M58 is based on R580, in which case your hypothetical M68 would be a downgrade since R580 should have 48 shader units. Unless of course Mobility R580 is castrated to a 8-1-3-1 design (but that can't happen, right Dave?) in which case 24 shader units would progress in orderly fashion to 36 units. And the circle jerk continues merrily on.

    It just peeves me when they don't fill in the boxes. :???: :)

    Could ATI be misleading by releasing a X1800 part that is not based on R520?

    What does that even mean? Does no one at the Inq ever bother to proofread Fudo's pieces before they go live?

    Those are his typical blunders - at least one or two in each article. :lol:

    Where did you get that "boxes" pic?

    Very interesting.

    Anyways its M58.

    The real question is, however, whether the mobility versions will also support dynamic voltage control via software. Although, I do see no reason whatsover for this to be not the case...

    The pic came from a French source (that quotes everything Fudo reports).

    From recent discussions about desktop vs. mobile ASICs, we've been led to expect that the cores will not change. So considering how rushed ATI was to get R520 to market after fixing the silicon, how hot/power greedy it gets at 625MHz+ clocks, the fact that the OEM cycle was already missed, and the advanced state of R580 development, it makes more sense that they would jump straight to an R580-based high-end mobile part which could theoretically be released near-simultaneously with the desktop version and regain the DTR performance lead unequivocally. There is talk of new power-saving technologies, but I still don't see how they are going to get a 48 pixel-shader core beyond 500MHz in a notebook.

    FYI, there also is M59. You can take guesses now, which one that may be. ;)

    M59 is the version they are making for me. $1m special order. I know, you can stop being jealous now.

    Where do these Sunrises and caboosemooses spring out from? :lol:

    Either an 80nm shrink or a speed bumped update of M58 :?: What's almost as interesting in that pic is the fact that there are two boxes below Mobility X1600 on the performance scale. Mobility X1300 occupies one of them but what about the other? I would have expected one slot below X1600 (X1300) and one above it (X1700). :???:

    That picture is impressively accurate.

    ATI is pulling an NVIDIA, so to speak. Guess the new name, shouldn't be hard to determine :)

    I don't like how I can't edit posts :(

    #1. thanks for linking me to the pic


    #2. ATI generally has a 14W TDP for midrange and 35W TDP for high end. I got this info from some Japanese article a long time ago and the info seems to still hold true :)

    7800GTX Go is running at 67W, up a bit (<1W) from 6800U.

    I would love to see a 35-40W X1800 :) I think it's more likely that the X1800 is 8-1-3-1 though, or something like that. This will allow clock speeds to be lower, yet still maintain a very nice die size.
