What do you mean? They included DDR2 and DDR3 in a wide range of speeds and came up with those numbers. If you look at the spreads in the render tests, you can't see a pattern that says "DDR3 is better when rendering" - the differences you do see are 1-2%, which isn't statistically significant, and it doesn't even seem to correlate to the RAM type.

If DDR3-1333 RAM can't beat DDR2-667 RAM by more than 1%, I don't see why going from DDR3-1333 to DDR3-2000 would be significant except that you have to keep increasing the FSB speed to keep pace with the CPU.
