Hi Gene Parrott; You are right, the Nvidia takes DDR SGRAM, sorry for being sloppy.
Arrow only has one variety of RDRAM available, as far as I could find. It was a Samsung part, 128Mb, x18 -600, and they wanted $150+ for it. So I would have to suspect that RDRAM is not a big demand device for other than the well known uses of it. None of the 6 or 8 DDR devices were more than about $20, they are undoubtedly being put into a lot of relatively unheralded designs.
(Edit: I should note that the prices quoted at Arrow are typically much higher than the prices that an OEM or a reseller would pay. Instead, they are the prices that a little R&D company would pay for the parts they would put into an early run of 20 or 100 prototypes. To get OEM pricing, call up the distributor (get the distributor number from the website of the manufacturer), and ask for "budgetary pricing". Be sure and have the part number you want, complete with all the extensions that specify ribbed or plain, etc., better, ask for pricing on a list of a dozen or so more or less equivalent possibilities, so you can find the cheapest. Quote a quantity that is reasonable, say 100. After getting the cheapest part type, ask for prices on it for 1000, 10000, and 100000 per year. The best places to deal with are the ones that publish tables of budgetary prices. That way you don't have to fish around to find the cheapest package. When asking for budgetary pricing, be prepared to supply your work phone number, and what company you work for, and sometimes what kind of product it is going into. In addition, they will want to know what city/state you are calling from, cause they divide stuff up for their sales force.)
It sure looks to me like the memory industry is well on its way to completing execution of its plan to obsolete RDRAM. But it will still be quite a while before this becomes totally obvious to the consumer.
