Hi John Fowler; Some reasonably ball park figures for percentage difference between DDR, SDRAM, RDRAM for a typical mobile computer. Total power computation for a typical mobile processor during hard use might be 20W. Of that, the processor will take the bulk. SDRAM memory would burn about 3W (at 500MB/sec bandwidth), with DDR at 1.5W and RDRAM at 1.7W. There isn't much difference between RDRAM and DDR. The savings is in the difference between those two and SDRAM. This would amount to something like 1.5W/20W = 7% power savings. I know that 7% may not seem like much to marketing, but you have to remember that the engineers fight over pretty small items like this. (G) Look at what AMD and Intel are doing with regard to 1 or 2% differences in performance of their processors, for example. A better way of putting it is that after using your laptop for 2 hours, the DDR gives you something like an extra 8 minutes of work. -- Carl
