That connector you circled. That is so the second GPU can communicate with the PCI-E bus.
Yes, this is because the first board has the secondary function of being an expansion board just as I said. You can
see, clearly as day, that it has a specialised 8x PCI-E connector on it, which connects to the specialised 8x PCI-E slot on the second card.
8X per GPU. Add a second GX2 on a 32X PCI-E SLI board, and what do we have?
You have two modified GO 7900 graphics cards. One serving as an expansion board, the other serving as an add-on card.
4 GPU's using 2 (TWO) PCI-E slots. I'm sorry dude, but there is no way you can call a single GX2 two video cards. When separated, can they work individually? No of course not. It is one unit and rather than making the card a mile long, they used 2PCB's. I don't see the problem here.
No, eight PCI-E slots. Did you look at the diagram? A "single" 7950GX2 uses
two PCI-E connectors. :roll:
