in my head... basically involved checking the number of shaders rumored and also assuming clock speed increases... net result, was wrong on the number of shaders(RV770 side) and clocks(was expecting 10-20% more clocks 50% more shaders and assumed around a 10% boost from the faster mem) but end numbers were right due to architectural improvements.

similar nv side expected lower clocks and 240/128 = 1.875 and 10% lower clocks and it's right around 1.7

all in all lots of speculation.
Even if they pulled off that incredibly complex feat (which they didn't) with the unified memory, there's no reason that that would imply greater performance over regular crossfire.. it just improves compatibility a great deal. Also, you're still going to have things like microstutter.
