This benchmark [1] shows little difference between DDR2 and DDR3 running on enthusiast hardware. DDR3 runs at a lower voltage which is supposed to result in some power savings, especially critical in most server applications, but their benchmark showed little difference in power consumption as well. Multiply the difference out by typical server memory configurations and it might be more significant. http://www.xbitlabs.com/articles/memory/display/ddr3.html http://www.xbitlabs.com/articles/memory/display/ddr3.html
