"does DDR really save that much? " Two factors come into to play. 1) DDR runs at 2.5 volts instead of 3.3 2) It is active for a shorter period of time for the same amount of data. So exactly how much power would be saved depends on the system and how it is used. In general, DDR uses roughly 70% of the power of SDRAM. Hmm, let me go to the Micron site. A typical 128 meg SODIMM draws about 8 watts max, so a guess of power consumption of a DDR module would be 5.6 watts. Now this would be only a 2.4 watt savings, but still a help. Two would put it in the 5 watt range. 10 watts, well that would be a lot of RAM. A better statement would have been 2-5 watts savings.
