I wonder if Dual Channel DDR2 is faster than Single Channel DDR3 or that DDR3 is so much faster that the Dual Channel doesn't matter.


The DDR3 is much faster, it's been proven (through testing) that dual channel does not offer a particularly large increase in preformance. Especially not enough to out weight the base line performance increase DDR3 has over DDR2. Toms hardware has a pretty nice breakdown of the modest performance difference between single and dual channel.

    Under those same test conditions, the performance difference between DDR3 and DDR2 would be even more modest. – David Schwartz Oct 3 '11 at 20:22
