Radeon HD 7990 delayed
According to ORB-Hardware Radeon HD 7990 may be delayed because AMD cannot produce sufficient cooler for this card (which requires lots of power – far more than Radeon HD 6990). Card is not planned for first and second quarter of this year.

i hope so, those lights would piss me off
They would also be a waste of precious wattage...

pictures are apparently fake.
Woah... That is one sexy card! 
I may have to pick me up one of those when they drop...
Glad to see the fan back on the front end of the card, as I was never a fan of the 6990 central fan layout. There really was no advantage gained from that design...

Fucking sweet. Two 8-pin connectors mean I smell POWER POWER POWER draw like never before. End mounted fan means no air barfing back into a case, if that's your thing, but 2nd GPU will be hotter.
The 6990 has 2x 8 pins.... These pictures look correct to me though. I was hoping for 3x 8 pins but didn't expect it to happen. The fan looks a little larger, or it may just be more open. Hard to tell. The 6990 fan design sucks. Not sure why anyone defends that design. Can't control the heat, if its just blowing out both ends.
It may be how it will look, but that looks like CGI so they can just as well be fake.
I wonder if the red accents really light up.

Exact specs haven't even been "leaked" (although companies now have timelines for their "leaks") yet. No way it is March 6th. Gamers need time to commit to $850 and specs, and early previews, websites talking about they have one but are NDA until March XX, etc. None of that has happened and usually all that occurs weeks (plural) prior to release date.
Roger that. What we may expect is the release date to be announced at CeBIT. I expect that date to be a few months away, though.Damn it.
I was getting excited about the 6 March date
They are supposedly releasing the Pitcairn chips so that may be good as well for better $/MH ratio

I heard a rumor that March 6th is the release date. Anybody know if this is true?
Yeah. That is what I heard too.
I still think getting 1.3 ghash/s out of a 7990 will be pretty easy.
After all, getting 440 on a 5870 = easy and getting 800 mhash/s ( not quite double 440 but a 7970 gets 700 easily ) on a 5970 = easy as well so ...
about march 6th online anywhere. Seems like they would have announced something if it was going to be that soon.

Yeah. That is what I heard too. Are you guys kidding? This is the release date of the 78xx series.

Hopefully they will put 3x 8 pins on the 7990. There are cards out with 3x 8 pins, I would think it could reach 7970 speeds if it was built that way. I can't get any more hashing power out of my 6970's then my 6990. They both run at 440hashs, if I raise them above 950mhz they because unstable for things like gaming. At higher clocks like the 7990 should be able to do, max power draw should be a issue with 2x 8 pins.
Yeah I was able to reach 825 MH/s on a full EK waterblock at about 1300 MHz core. The voltage needs to be around +1.1V for stability, and artifacts begin to appear significantly at that speed, anything higher than 1350 MHz crashes fast on 1.1V (1375 MHz = 50% overclock, crashes in an instant, unless doing max overvolt, but not feasible for many obvious reasons) on watercooling. On air cooling artifacts appear around 1225 MHz (~70 C), watercooling around 1300 MHz (~32 C); temperature appears to be factor in this, but I won't get away with this for long since winter is ending, and no more freezing outside air will be chilling my 200mm radiator.
Without a doubt the 7990 will reach over 1 GH/s, but whether a 7990 could attain close to double the hashing rate of what I reach on my 7970 I would not be easily convinced, unless someone can accomplish it through trial (even if any modding is needed to be stable). The major issues to consider is the amount of heat a single 7970 can produce just through its own vrm; one could speculate that a 7990 would draw close to 500 watts on a single board. Thus the amount of electrical current needed is extremely high, and cooling would probably be the top concern for an overclocked hashing 7990; besides when you begin to overclock, the current also rises up to a point, until which the voltage will need to be raised. I am just wondering how a significantly overclocked 7990 would stand on air cooling: temperature-wise, power consumption-wise, and then noise-wise. I guess all we can do is wait and see how this upcoming video card performs once it is released.

They was someone on this board claiming that they were getting 800 mh/s from a 7970 that was watercooled. If you can cool the card effectivtly I think you may be able to get to 1.3 gh/s. But it will hit at least 1.0 gh/s. Though the power used is going to be huge though.
