    Sums up my feelings. It seems they were well within reach but didn't go for it

    Of course that's pending results. If its < 400mm^2 and 190W and matching the GTX 580, it's a pretty damn good engineering win that's for sure, and the prices would be nice

    I still have the feeling that this is wrong , and 1536 is not the number of shader processors , Remember the time before HD 6870 ? how we all argued whether ALU count was 800 or 960 or 1120 or 1280 ? with several sites saying 960 or 1280 , and then the truth got revealed two days or so before launch ? I think we are in the same situation here .

    If the XT is really a 24 SIMD part

    The supposed switch to 4D saved them 10% die area and if the Cayman XT has less lanes than Cypress then why is its die 15-20% larger? The other arch improvements dont sound like they were anything radical to consume a greater die area.

    Something doest add up..

    459,00 € PALIT GeForce GTX 580
    446,49€ INNO 3D GeForce GTX 580

    HD 6970 (479€) will be slower than a GTX 580 (446€) ? :???:

    MSRP (or pre-release gouging) vs Street price.

    eh whatever life is too short to worry about SPs and performance. I'm going to sleep wake me when 2x Cayman are released

    I'm playing Lotro on eyefinity, just 5040x1050 though. What card you using - even my 5770 ran it well with 0xAA (obviously) and mid-high settings.

    But yeah I get your point. I signed up for TOR beta testing, giving eyefinity as my reason why I should get a spot ;) Too bad they left it for North America only.

    I don't think it will have eyefinity support to start with unfortunately. If AMD had any sense it would, but...well you know what they are like lol.

    That won't happen again. nVidia will have their own dual GTX560/GTX570 card to take the high end :wink:.

    if it's dual GTX560, do you expect THAT to beat Cayman too?

    It'd have to be a dual 580 wouldn't it? Let me know if you have inside info on this happening, I'll want to invest in a PSU company.

    If 6990 is dual 6790 and 6790 is 10% under 580 GTX then 6990 won't be "beatable" for the foreseeable future as a dual 580 GTX wouldn't be reasonable.

    BTW, how is Crossfire these days? Can a dual card (with the normal compatibility and stability issues) really be compared with a single-gpu card (typically more stable and compatible)?

    If the answer is yes...

    I think he was going that it wouldn't have the dual market to itself unchallenged not necessarily that it wouldn't have the performance crown.

    March 25th 2010 qualifies as "ages" ago!? Man, I'm getting old...

    I've had a 5970 since launch.. it's OK. With certain games, dual GPUs still have weird microstutter issues that only can be observed if you are pushing the card to its limits. Which, in my opinion, hurts the longevity of these cards.

    For example.. I can run L4D2 with 4XSSAA @ 2560x1600 on a 5970 but when it dips to 50FPS the perceived frame rate is something more like 25 FPS.

    You are also entirely dependent on drivers. Especially in the case of the 5970, as there's way to disable the second GPU via driver. So if there's a problem, you have to wait for AMD to fix it.

    Personally, I'm never going back to dual GPU. Waiting for the 69xx series so I can sell this thing off. Though I may end up going for the 580 if the 6970 isn't all it's hyped up to be.

    It isn't.

    ATi's driver support is still as bad as ever, people say it is getting better, but honestly they are either lying to themselves (fanboys) or are being deceived. SLI is better, but I would always get a single GPU card. Seriously, every time.

    I think a dual GTX570 would be doable, but it would be more like dual GTX569 or something, with 2 SMs disabled for 14/16 on each card and a total of 896 SPs, it would be competitive with 6990. Definitely. If you take around 10% off the GTX470 power consumption and multiply by 2 you would get the power consumption, and it would be possible. Plus with just 14/16 active SMs Nvidia could bin for lower temps.

    Indeed. If we aren't going to include 5970 we shouldn't include GTX295, and 5870 was around 20% faster than GTX285.
