    Well we now know the answer to that one as well with the x1400 being introduced today as well.

    If M59 is based off R580, then what is M58? This is the main question here.

    Yes, but do we know what core X1400 is based on? A faster version of RV515?

    Edit: and here we have a reference to Mobility X1500 :?: Typo, I gather.

    Go back to the original thread Dave just linked to - it's logical to assume that M58 was a mobile R520, but that ATI decided not to go into commercial production with this part and jump straight to R580 instead. For whatever reason, there is still no M59 (or R580, for that matter) showing up at PCI-SIG despite this being a different ASIC that requires PCI-E compliance.

    That struck me very much as a worried PR department getting a jump on their spin.

    And yet I don't see how they could release a mobile R580 that would adhere to those conservative thermal limits.

    It's natural to assume a mobility X1800 will compete with the Go 7800 and a mobility X1900 with the Go 7900.

    With the quick release of the R580 in replacement of the R520 I think it's safe to assume any newly released R520-based products is merely the same thing that ATi is doing with the X800's right now: burning off excess inventory to help bring in the M59 faster.

    Well now we've got a M52T :?: showing up alongside RV530GL and the RD580 reference platform. Funny that R580 hasn't appeared yet.

    Hmm... perhaps it wasn't evaluated at the most recent Compliance Workshop (#48) running from 5-9 December, 2005 or it may have been and the PCI-SIG are still reviewing additional checklists submitted since the workshop before adding it to the list?

    I sent an e-mail on December 15 asking for a possible ETA on the next update to the PCI-Express Integrators List (at that time the last update was November 22, 2005) given the recent workshop and was told that it usually takes several weeks to rollup the test results and review the checklists submitted following a workshop. I assume that the recent additions, such as M52T and RD580 are from that workshop.

    M56-d?

    Apple puts M56-D (X1600) into iMac Intel Desktop...
    [​IMG].
    I would like to ask, is this a Mobility or Desktop GPU core? Since AFAIK, M56 is a Mobility X1600 GPU.

    My first thought when seeing the M56-D codename was that it could be a 80nm variant of M56, as it is known that ATI are moving to 80nm for cost reductions, however I refrained from mentioning this possibility as ATI typically adjust the codenames for die shrinks of the same ASIC, e.g. RV360 (130nm) --> RV370 (110nm) and up and until today, there had been no 80nm production announcements.

    Looking at Dave's recent X1600XT and X1300Pro article, the M56-D die doesn't look noticably smaller than the RV530 die either, so I would lean towards the M56-D being a mobile X1600 ASIC, with M56's inherent power saving tech and thermals, uprated for desktop use at higher clockspeeds than M56, but with better thermals, etc than RV530.

    There could be and probably is, a better explaination. :smile:

    Yes, I seem to agree with your explaination. There are a bit different on both core (RV530 and M56-D) on the second line printed on the core. For RV530 it is 215CACAKA13FG (according to the page you pointed), but 216DLAKB24FG on M56-D (not sure 216 or 215 on the image, but look alike 6 than 5). Yes, just coding different but physically look almost the same. I also would like to see any review on this iMac Intel with X1600 on how could it be capable of playing QT H.264 1080p playback :cool: . Hope it would come shortly.

    I almost forget this tread already :smile:.
    Anyway, I think that kind of weird spec is only to make the chip fit well within power consumption and thermal rating on laptop parts... that resulted in cut-down quad and clock... until it looks merely like a mobility X1600 :sad:. Hopefully, there would be something that make different except for the part of 256bit memory interfacing... even if this core might end up with what people suspect as X1700 would be...

    Arhh... that's a killing pic... duo heat hugh piping for cooling the GPU module :twisted: . It seems all the GPU module is concealed under CU heatsink. This thing could be fitted onto only DTR with big cassy. Sound hopeless for ordinary laptop part by the look of it.

    ATI high-end parts have a maximum TDP of 35W. I would assume that the X1800XT 256MB fits this TDP as well.
