    So it is true! NVIDIA does have a single-PCB GeForce GTX 295 accelerator in the works, and partners already seem to have access to it. The card must have had some serious development put into it, given the sheer complexity of the PCB (to cram two G200b GPUs, their display processors, and the PCI-E bridge chip, along with 28 memory chips). The accelerator first surfaced in the form of CAD drawings, in March.

    The PCB is pretty straight-forward: populate all the important logic on its business-side, and the memory on either sides. The card maintains its requirement for 8 + 6 pin PCI-E power input. Its VRM is spread across two main areas, to power a GPU system each. Internal SLI connects the two systems, while also providing support for Quad-SLI. Each GPU features 240 shader processors, along with 896 MB of GDDR3 memory across a 448-bit memory interface. Also pictured is the cooler: A fan nucleates the cooler, and blows in two opposite directions. The air is guided by the shroud onto two dense aluminum fin arrays that cool each GPU-system. The back of the card may use a heatspreader to cool the memory, like how the GeForce GTX 280 does it. While we don't expect this design to bring down the retail price of the card, we do believe that the design is mainly to provide partners, and retailers with decent margins that make selling the card a worthwhile venture. With the older design, it might not have been the case.

    the chip packaging looks gigantic on single pcb.

    Interesting to know how this cooler will perform..

    Yup its about time to rebadge the same card to resell it before releasing the GTX300 line up.

    I am guessing single pcb = lower costs. If retail price remains the same, then lower costs = higher profit.

    smaller. lower cost. easier to produce. easier to cool. 'safer' since they dont have to worry about the joint between the cards failing.

    judging by that last pic, i'm expecting to see 775 coolers bolted on.

    While i do think that putting it all onto 1 pcb is a good move by nvidia, i'm not sure i'd be happy with a G200b gpu's heat being blown inside my case, could get toasty with a long gaming session.

    the cooler looks nice.. imho it would have been nice if they put 2 fans in the card (1 for each GPU) to properly handle the heat of this card.. still glad that nvidia came up w/ this design for the gtx295, this one is better than the dual pcb design :)

    It blows air out the back of the case at least for the back GPU, but it might have a vent out the front, probably does otherwise no clue where that air is going. Either way looks nice and should get some better profits and allow more cooling solutions.

    There's nothing really to catch up to. NVIDIA's dual-PCB designs with the 9800GX2 and GTX295 have superior thermal management. The only con is its manufacturing costs. With this card however, it doesn't look like NVIDIA is planning to pass the benefit of lower manufacturing costs to the consumer. We'll just have to wait and see. Rumored release date: 1st week of June.

    Half of the heat is being sent out of the case, so it isn't all bad.

    Doesn't look any longer than the HD4850X2.

    I didnt think they were that long. That means id never be able to fit them in my case.
    Good to know.
