Perhaps, he just is not good at arithmetic.<G>

Hi pheilman_; Thanks for the note. Yep, the 144% is a mathematics error. (Which means that DDR was actually cheaper than I calculated, LOL.) I'll correct it when I update the figures tomorrow. All the calculations are by hand, I use an HP calculator, and I do make mistakes. That's why I list all the derivations. I run it through the calculator, and if it looks about right, I assume I haven't made any errors. By the way, I believe I may have made another error the other day where I counted a PC700 RDRAM RIMM as a PC800 by mistake. The meaning of the final column is a measure of which memory type is ahead in the race to achieve SDRAM pricing. Both are a long ways off right now. The formula is: (RDRAM/SDRAM - DDR/SDRAM) = (RDRAM - DDR) / SDRAM so it is a pure number. I think of it as the difference in price of the two technologies, scaled to the current mainstream memory price, and I think it's a reasonable number to plot. Philosophically, it is my belief that RDRAM and DDR are not competing with each other nearly as much as they are competing with SDRAM. One of these two memory technologies (and I know which one) is going to grow to fill the SDRAM niche, neither of them has enough of a niche to bother with the other chasing after. -- Carl P.S. I'd update the PriceWatch figures but for two days now, Saturday and Sunday, the figures have come out identical for all three memory types, with no changes in any prices. Also the number of DDR motherboards appears to be stuck at 339. My suspicion is that their system is having problems, so I'm not giving an update.
