Easily man...

A LOT less latency than regular cross-fire.

You see, regular cross-fire has to do a majority of it's communication through the chipset. Meanwhile this card has it's own splitter and does it's communicating all on card. As such, there's less latency all the way across the board.

ALL current multi-gpu set-ups have to duplicate data for each gpu in ram. They have to, because both gpus need the same textures and shader information as they both work together to render the scene. Essentially they all run as if they had the same amount of ram as the lowest card does. That's just how things have to work currently, and why I believe the R700 will have to have an external memory controller for the MCM package.

To sum it up, this card is like a lower latency CF set up.

So how would you explain similar results in 3dmark?

Im not saying that your theory is wrong it just doesnt seem logical. if it was running lower latency, then surely like i said before it wouldnt perform even close to what two singles in cf can score? [Im talking about stock speeds here.]

and as you see in someone else's post above the powercolor scores 23000. with a factory overclock.

Im just trying to understand your reasoning.
