PR departments can say what they want. It is just a tweeked Radeon x800 core that seems to clock a tiny bit higher. The performance differances should not be that big, likely around 10%, but the supply is supposed to be better for these. This is not their DX9.0c core. That will follow in the Spring time last I heard (and might be an SLI board).
