From Powercolor, we’re seeing a technological showcase with what they call the 6970X2, bringing the X2 name back into the scene (unofficially). This PCB uses a Lucid Hydra chip (rather than a PLX) for routing to combine two full-speed 6970 chips powered by the three 8-pin PCIe to give that magical 600W number.
They had a pair of these cards in Crossfire into a system for us to look at, even though with CPU and everything else, there was only a 1200W Gold PSU powering it all, possibly suggesting that the power consumption is below 600W, and performance is only a few percentage points higher performance than the 6990, if any.
We were told that Powercolor don’t have intentions to bring this product to market unless they see a demand for it – they were more inclined to show off a 6950X2 which should enter into the market between the 6970 and 6990 in terms of performance. No word on pricing or release, though.
