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.

Waits for someone to asking if it comes with its own nuclear power plant to power it.
Happy now newtekie
if they are truly launching a dual 580 it will be epic, expensive, and powerhungry.
edit: also there must be 12 more ram chips on the back if this is truly supposed to be a dual 580.
WHY!!!!!!!!!!!!!!!!!!
YOU DO NOT BUY HIGHEND CARDS TO SAVE POWER YOU FREAKIN IDIOT !!! :laugh::roll::wtf::shadedshu
can't wait for it.
now when they make a new power guzzler nobody will be able to point the finger at the HD4870X2 lol
Yeah, the power issue is irrelevant. The 6990 will be just as bad.
I dont think both cards will be very good thermally or acoustically. But you never know...
I think what they can do is set up the power circuitry in a loop so when one gpu down clocks the other one upclocks and that might help
Ima guess 370 watts with limiter at least 400 without
?
The cooling is going to have to be very creative, so is the price. :wtf:
We're talking about a ~550W card here. Even if they figure out how to fit it in regular cases, it'll need a huge cooler (3-slot?).
But a dual GF104 card, with all 384 ALUs enabled in each GPU, would be much more believable.
Having the largest carbon footprint is the only claim to fame my poor card has left. :cry:
Anyway ... I hope this thing rocks. The GPU war never gets old in my book.
A 580 is currently power limited due to spiking above the total available power of 150+75+75=300watt max. In tpu's article here the 580 power limits itself after spiking up then it settles to a max watts of 200(question why 200 and not something more like 250 or 290??? Probably due to the limits of the electronics used on board...). One question I didn't see answered was did the performance increase proportionately to the increase in power used after the power limit was taken away?
In any case the point is a 580 really needs an 8pin+8pin power to keep itself from being power limited from the cables(let alone the electronics used on the board as well as possible problems with load balancing), so how is a dual gpu going to fare better if a single gpu is already power limited? I guess I will just have to wait till someone who actually knows what they're talking about gives a go at it, or just wait till the card comes out and reviews are posted.
ah! My guess: The gtx580 is so powerful to the point it has to be power limited when used to its fullest, however most applications will be limited by the weakest link in the gpu before using the full power of the gtx580(example: cut the rops in half and suddenly the card is limited by the rop count). The dual gpu card will still need to be power limited, but it won't matter as most normal applications will be limited by the weakest link in the gpu before reaching the power limit.
even downclocked a dual gf110 would be amazing, now I'm starting to wonder if the 6990 is going to dominate as the 5970 has, the 5970 didn't have any dual card competition.
