but whats the point of gtx460 quad sli?
gtx580 quad sli is possible with 4 cards, so...
its not very user friendly, but i find it hard to imagine that using 2 dual 580 cards will be MORE user friendly than 4 individual cards... 2 dual cards will be slower, noisier and hotter...
so yeah, i dont really get the point of this...
the pcb is surprisingly small though... well engineered pcb...
For a high-end card is there any reason to be limited to air-cooling?
This wouldn't fit in many mATX cases due to length, so would it really be a big deal to ship the card with a waterblock and the option of a self-contained pump/rad combo?
2 GPU's would take up 2 pci-e slots, plus the radiator attatching to a fan mounting point either internally or externally.
you mean, dual-head cascade + caseQuote:

if it would be, youd see a lot more companies offering 480s with waterblocks or unconventional cooling solutions.
Maybe the board is a GF110 + GF104, GF104 being advertised as a co processor for PhysX.
Why don't they just encourage people to buy 2 x 460 / 2x 470 / 580 cards and give some discount.
Then they could edit sys info to tell people they have "GTX 695" or something installed on their system.
People can then enjoy god-like performance and be happy :D
I believe GTX570 with 480 Shaders (15x 32) and 320bit memory could have 210-220W Max Graphics card power usage, that’s the same as GTX275.Quote:

youre on to something and I further add to your input by saying they could sell sli combos in one box. picture a giant box that bundles two gtx 460 for 399$ with a full crysis 2 included. Now whos gonna ignore that!Quote:

The disadvantage is the extra heat and power in a single card. The PCI-power-limitation can be solved by adding 3 (or even 4) 8-pins connections, but coolers are still a big problem. A better cooler is needed for such a power-monster for sure.
This seems like an interesting solution for guys running mini itx boards like myself, specifically SG07 or capable cases.
I have a gtx470 now, I wonder how this'll compete w/ the 5970 or gtx580 in general.
Way too low power consumption estimate.Quote:

system load power: http://www.anandtech.com/bench/GPU/1...69.168.166.167
an extra "275" in the 295 adds ~50W.
an extra 285 in SLI adds ~100W.
system perf: http://www.anandtech.com/bench/GPU/88?i=169.168.166.167
an extra "275" in the 295 adds ~15fps
an extra 285 in SLI adds ~22fps.
the 295 is more efficient. they are able to produce a card with two hot chips by introducing new efficiencies.
can they do that with GF110? consider that the power draw of the 275 is close to the power draw of the 470: http://tpucdn.com/reviews/ASUS/GeFor...power_peak.gif
if the 570 is also close, we can imagine a dual GF110 card is doable.
you hit the nail on the head, people don't seem to under stand that a dual card is not 2x the power of a single one. there are many improvements that can be made to lower power consumption of 2 full cards. I think dual GTX 570's is perfectly doable...Quote:

It's doable i think two GTX 570 gpu's at lower frecuency, 600Mhz with lower voltage.
It should be 35-45% faster than GTX 580, but it would be faster than 6990? It depends on what 6970 is.
The 6990 seams to have gone back to drowning-board, and delayed to next year, just after they saw the GTX580, apparently.Quote:

So yes, indeed, it will be interesting to see what comes out of the new-drown 6990, but these delays are suggesting that AMD is straggling. Nothing is clear yet thought, we have to wait and see.
Its not back on the drawing board it was planned to be released 30 days after cayman but as cayman got delayed due to production problems so did antilles. it will not be a paper launch on cayman though and antilles is still dual cayman xt with lower clocks, here is the latest info leaked and what the gtx 595 will go against:Quote:

Yeah, I've also heard the rumors that explains those delays smoothly. Lets hope those are the real reasons for tow "strange" delays.
To me, those delays suggest performance-trouble in AMD-camp, but who knows maybe you are right.
Anyways. lets hope AMD can compete on performance, with or without going back to drown-aboard, it will be good for competition. With a aggressive nVidia on the ride, a competitive AMD will bring out better and cheaper GPUs from both camps.
new Details about this card GeForce GTX 590 :)
----------------
GeForce GTX 590 in February with dual GF110
the Name will be GTX 590 not GTX 595
NVIDIA has already set the launch date of GeForce GTX 590 to sometime in February

With dual GF110 GPUs comes a big memory buffer. GeForce GTX 590 gets 3072 MB graphics memory work with and with dual 384-bit memory buses bandwith shouldn't be a problem. Reference design set with large centered fan
We have no pictures to show of the card since NVIDIA is holding everything tight before the launch of the new flagship. According to reliable sources to NordicHardware the reference design is set and as expected the card will get a full-cover cooler with a large radial fan in the center. The fan will be around 90mm in diameter and hte card will be very similar to GeForce GTX295 (generation 2), but most likely a bit longer.
Launch in Febrary with a surprise
NVIDIA has already set the launch date of GeForce GTX 590 to sometime in February. The exact date was not revealed and from what it seems like it is aiming for a launch similar to the one of GeForce GTX 580, in other words as soon as possible to surprise competitor AMD and the media.
Today we know more about GeForce GTX 590 than we know about Radeon HD 6990 "Antilles" that sporting dual Cayman GPUs will arrive in February. NVIDIA beat AMD with the new performance series a few months ago, but the question is if they will do it this time too.
There's no doubt in my mind these things have been kickin in a development center somewhere. Considering how close power consumption is between the 570 & 6970 I can understand the feasibility of bringing a dual 570 based card to market if AMD can bring a dual 6970 card to market but a full dual 512 shader in retail will definitely be interesting to say the least.
I'm a bit skeptical but with how they're getting to the point of firing on all cylinders again with their lineup things may get interesting for the top performance enthusiasts.
If those specs are true, then this card will be expensive, though I still find it hard to believe that NVIDIA slapped two GTX 580's into one PCB.
" a lot "
hmm..
it can be done, but I'm skeptical because gf114 is so good. since they are constrained by power, I feel like 300W of gf114 might be just as good as 300W of gf110. BUT maybe the underclocked 580 yields very high efficiency. we've never seen anyone benchmark an undervolted 580 to see.Quote:

yeah.... to me, that part makes it all bull$#!7. if they release a duel card it will have the 570 core.Quote:

I believe, 2x GF110 low clocked can do the job, even if im a little bit sceptic.
