ATI's Dual GPU HD4870X2 pictured

AMD still haven't finished the work on its in-house PCIe switch and as such is still using a PLX solution. The card is also using digital PWM, a pair of them to be more exact, one for each of the GPUs. The advantage of this is that the digital PWMs take up a lot less PCB space than the analog PWM design of the Radeon HD 3870 X2.

The power connectors aren't angled on this card, but that might yet change before the final production cards arrives and the card uses one six-pin and one eight-pin power connector.
