    why would the highest end products not have 2 connectors. when was the last time that happened. this is not news unless the displayports are news too

    but as said above this has to be 6950 due to a cut down VR and 2x6pin connectors

    Here, let me tell you how wrong your statement about use of vapor chamber use is: 100% incorrect.

    The rumours all point to this chip being amazing, dire or somewhere in between. Roll on release day...

    Where is your proof? AMD seems to think otherwise

    "We first started shipping with Vapour Chamber coolers with the ATI Radeon HD 2900 series on products and have continued to develop them on every generation since (with patents pending); we will have further refinements on upcoming GPU’s. With regards to variable fan controllers it is hard to see what is new here – boards with 3 or 4 pin fan headers should have fan control anyway; with the ATI Radeon HD 4000 Series and on we moved from external controllers to fully programmable system on the GPU’s own internal microcontroller; this enable a fine grained, continuously variable control that handles multiple fan curves which change according to the temp ranges you are dealing with." - AMD North America PR

    thanks Safan ....

    anyway they use it since a long time, but they just no more advertise about it ( note the 580 vapor chamber is a bit different )

    I thought the technology of vapor chambers were only used in the vapor x series from Sapphire. There are typically big improvement when using the vapor x series compared to the regular stock cooling.

    they use an advanced design, more efficient... but ATI use a similar vapor chamber ( but less efficient, and cheaper design on standard cooler )

    this statement is wrong...

    ati has exactly the same vapor chamber on its 5970 card, nvidia just failed ocmpletely with the 480 cooler and that's why they make such a big deal out of the 580 cooler

    Difference to NV? Ati paints the underside of the vapor chamber...

    i respond about the Sapphire Vapor X, not against the 580 .. the Sapphire one is more advanced of the one used by ATI(AMD) ... nothing to do with the 580 ..


    About Nvidia, it's not a question of fail or not, they wanted to show to the public they have work on the bad aspect of the 480 ( hot, power hungry ) and they have hype their solution.

    from a marketing point of view, it's a good move to show it.

    Correct statement bolded.

    The standard ATI heatsinks are not vapor chamber design. Anyone with access to a PC can google to see the stock ATi heatsink designs for each card.

    Here's the 4870 and 4890's (thanks to eastcoasthandle for pics) for example

    5970 uses vapour chamber, just to say. ATI/AMD uses vapour chamber on only their very hot cards. Hell, 4870X2 wasn't vapour chamber. 5970 required it.

    Not sure about the 2900XT though. They are not marketing gimmicks. If they are, AMD wouldn't have used it themselves on stock design. Nor nvidia.

    While I agree with your first point, that leads me to ask you...Are you sure about (the whole of) your second?

    but as said above this has to be 6950 due to a cut down VR and 2x6pin connectors
    Higher density but only 6Gbps... there was no delay with the memory, they have had these ICs available since before Barts launch, just no reason to use them on a midrange product.

    Edit- Should be some solid leaks in the next couple of days, too many cards in the wild now.

    I like vapor chamber. To say every reference ATi product since the 2900XT used it, is blatantly incorrect.

    Thats a Sapphire card (and not even their regular model), not an ATi reference. I do also own a Sapphire 4870X2 by the way, no vapor chamber on it at all.

    I was under the impression that looks a lot like a vapor change cooler, as does the one on R600. Of course you're right about the other stock coolers, it's not at all on 4800 single GPU series, or any others for that matter other than 5970. I figured they were deployed by AMD in certain scenarios given the use on 2900XT, 5970, and I thought 4870x2; the only products that needed to dissipate that much heat per core/area (5970 even being overkill at stock clocks...It's obviously there because most will increase the voltages from 5850 to 5870 levels voiding PCIe spec). Using it only on one core does make some sense in 4870x2's scenario, given the need for a fan and sink anyway, and it being the highest load power draw for a stock card ever made.

    Yours has two flat sinks? Huh. Perhaps you have a non-ref model (with twin fans or something)? I was always under the impression it was the case for the stock cooler given reviews show one GPU with significantly lower temp, Theo declaring it so (as credible or incredible as he may be) and it was right when AMD made their announcement about partnership with Celsia on vc cooler options, etc.

    Not worth a fight though, amigo...and this is the wrong thread for that anyway.
