NVIDIA Readying Dual-GF110 Graphics Accelerator, Eying Total Performance Leadership
NVIDIA stunned the computing world with a speedy launch of the GeForce GTX 580. The GPU was able to increase NVIDIA's single-GPU performance leadership, and also iron-out some serious issues with the power-draw and thermal characteristics of previous generation GeForce GTX 480. It is now that a dual-GPU implementation of the GF110 graphics processor, on which the GTX 580 is based, looks inevitable. NVIDIA seems to be ready with a prototype of such a dual-GPU accelerator, which the Chinese media is referring to as the "GTX 595".
The reference design PCB of the dual-GF110 accelerator (which still needs some components fitted) reveals quite a lot about the card taking shape. First, it's a single PCB card, both the GPU systems are located on the same PCB. Second, there are slots for three DVI output connectors present, indicating that the card with be 3D Vision Surround ready in a single card. You just have to get one of these, plug in three displays over standard DVI, and you're ready with a large display head spanning three physical displays.
Third, it could feature a total of 3 GB of video memory (or 1.5 GB per GPU system). Each GPU system has six memory chips on the obverse side of the PCB. At this point we can't comment on the memory bus width of each GPU. The core configuration of the GPUs are also unknown. Fourth, power is drawn in from two 8-pin PCI-E power connectors. The card is 2-way SLI capable with another of its kind.

Board layout pretty much looks like GTX295 single pcb. Would probly run ok on a 750w+ psu, with at least 48amps on the +12v. Im seeing a 600 USD tag there..
And that SLI finger, THAT SLI finger...That's waaaaaaaaaaaaaaaaaaaaay too low...around 750 USD should be more adequate...
10 years later 2000watt card?
At any rate, the 'spec' is anything but one, as we can see GF100/GF110 clearly can draw more juice under load than 300W at stock, and AMD/nVIDIA implement their TDPs differently.
One has to question this product though, power consumption Nazi or not. It's outside the pci-e spec, and (if a nVIDIA-sanctioned card) can almost certainly be seen as a concession that the same configuration using GF114 will not beat 6990...which is perhaps a given.
For it even to be feasible, it needs to be faster than the same configuration using GF114 GPUs instead, even at a greater clockspeed. Since we know GF104 GPUs clock into the 800+mhz range, and would assume GTX560 will be clocked in the 750-800mhz range, this would need to be clocked at least around ~600mhz. I wouldn't think there is a lot of wiggle room between that and what they could get away with using a < 375W spec, even using tricks like lower clocked/voltage (1.35v, 3.6/4.0Gbps) 2Gb (denser, not GB) GDDR5.
*thinks about the crazy frame rate this card in sli could get* I wonder how well a pair of these would do in 3dmark11.
maybe dual 570, or dual 560(gtx 460 @ 750Mhz) sounds more realistic.
The 6990 didn't even come out yet, so it's too premature to spectulate
it actually does have the 1038A1 like on the sample w1zzard used in his review but the other marks are different and the identifyer the GF110 at the bottom isn't there so this could actually not even be a 512sp(disabled shaders) part but still based on the GF110.
this will draw little more than a GTX295, while whoppin' it twice over.
good on them I say, get it out fast like the GTX580.
