    Wow theses run surprisingly cool for dual gpu solution

    Also great review as most are using i7s @ not the most impressive clocks for this cards review.

    Thanks for that additional info, Allan

    did you think that fermi picture that leaked the other day was fake? Theres another computer above it... I dont know... (sorry just related to uniqueheaven

    We actually were one of the first to post that http://www.driverheaven.net/news.php?newsid=296

    It was posted on Nvidia's staff page - I actually know one of the engineers. I see no reason for it to be fake as the A2 silicon cards were already produced for internal testing before A3 rolls out.

    Bookmark our news page, and try to limit your time on Anandtech ;)

    Oh and so you did, Sorry I missed it. It's a sexy looking card.

    I just to be able to compare Fermi performance to the 5970, and am wondering when that will be possible. I heard they moved to A3 silicon when means they probably didn't like the performance of A2, etc. Or whatever found a better way etc.

    I just was hoping to get a 5970, and wanted to make sure I was making the right choice especially since it got pushed back, Any idea if Sapphire will have a custom cooler by then (Jan 24th) ?

    Edit: come to think of it, I thought I remember seeing it here, and that's partially why the new newsroom is sort of confusing, you guys add so much stuff it quickly gets pushed back hehe.

    Sorry for that, Z

    Sapphire are already working on a custom cooling solution for 5970, I spoke with them a few days ago. I think the card is slightly more complex however than anything else they have had to deal with.

    They will crack it though, and I hope to review it here once they offer us one.

    Sounds like a plan Z, thanks for your insight. As always, you work to much, but it's not un-appreciated

    If I were AMD I would be embarrassed. What's wrong with them?
    Thank you for the info.

    make sure you get heatsinks for the memory too.

    First post here. I found the site looking for a CF review of the 5970. Good job!:D

    1- I found awful to compare single vs CF numbers, since these numbers are in diferent pages:sigh:. So i would still spend sometime at Anandtech:taste:

    2- The ideas for the heatsink are inoccent to say the least. It is impossible to dissipate soo much heat using a dual slot solution. The single blower AMD uses at least manages to vent some air outside the case.

    Putting heatpipes to the back of the card would occupy space near the CPU on single card setups and make CF really difficult , not to mention that it would divert heta that otherwise wasgoing outside of the case to the inside. and it would make a 2 solt card larger than 2 slots.

    Adding a second blower is even worst. Not only it messes with the airflow but also reduces the area of the vaporchamber/heatsink.

    The "best"way to use a hot VGA on air is simply take off the plastic shroud and add 2-3x80-92mm fans directly above the heatsink/vaporchamber. it will be silent, cheap. but will take at least 3 slots and turn the case in a furnace.

    Naturally watercooling comes to mind for space, silence and performance reasons.

    The review is mainly focusing on the CFx elements, hence the name of the review. We covered single 5970 results before in a dedicated launch review - it was merely there this time as an 'extra'. If it is a huge issue for you and you need to compare every figure, it is possible to have two browser windows open on different pages side by side.

    Yes, simply 'adding a fan' is not the only thing that would be needed, this is why we mentioned that changes would need to be made to the vapor chamber - we don't profess to be cooling experts as there is a lot of R&D involved - but we would like to expect that AMD - a multi billion dollar company would at least make the effort to try other solutions, rather than simply slapping in one of those tiny red fans from a previous bulk order 4 years ago. The point was to make people realise that there are alternative options, if the money is invested. Sapphire do it, so I fail to see why AMD can't at least try.

    Absolutely, but there was a conference earlier this year where a developer had a proposition for a very thin backplate which took up only a few mms, but was made of a very specialist material that could 'help' dissapate heat from the cores - the heatpipes were only 'fat' until they met this panel at the join to the rear so it took up very little physical space. You will notice in our mock up we didn't delve into an oversized cooler on the rear because the idea was not to use it as the sole cooling methodology but to help enhance the heat removal from the cores with the help of the vapor chamber.

    Yes, if the vapor chamber was kept the same design... certainly, but once again there are patients pending from a few companies we know with a dual dispersal heatpipe based methodology which not only means that more heat gets expelled from a dual core solution but also that the fans do not have to create noise akin to an apache helicopter. Simply adding a second fan is not the solution - but with some engineering changes, there is no reason why a cooler on each core is not feasible. Not quite as simple as that obviously, but once again it was just a rough mockup to offer possible alternatives.

    Watercooling is only an option for a select group of enthusiast user. There is still a huge audience, even on a site such as Driverheaven with a higher ratio of 'geek v ordinary person' who would not have a watercooling setup to deal with this. Self enclosed watercooling would be an option (and I know Coolit and Asetek were looking into it - but would probably once again mean dual cards could not be used due to the space needed), but we don't think it would be possible with such a high heat output board design.

    Honestly, and as I have stated before I will never understand why these companies don't flip their cards and have everything on top. So that the heat that's additionally on the board does not stagnate and flow across and is free to flow up, sure, it may get up near the cpu, but that's what exhaust fans are for. And it's only the excess heat not gotten to first by the exhaust fans.

    However DH mock ups, were simply a design idea, and at least someone is willing to recognize that by the next generation of chips, things will be so hot because of the 2000 or whatever number stream processors going into these beast there will need to be a more thought inclusive idea on how to re-direct heat.

    Nice review, insane performance.

    I presume you mean GTX285 tri sli on page 18 btw, or have I missed something big here?

    If I had limitless money, I still am not sure I'd buy this though. There's some shameful brand loyalty coming through here I fear, in the face of an obviously superior product (an essay for another day), but also they're just hugely overkill!

    Sounds like you prefer NVIDIA or am I mistaken

    I use to be hugely a fan of nvidia, but their ego as of late is bigger then their framerates, and they are really shoving me off, I've chosen to give AMD/ATI my money and will be getting the 5970 for my birthday. :)
