It's simply ridiculous to compare the price of two products at different times. A year ago, you couldn't buy RDRAM at current prices, nor could you buy SDRAM at current prices. So why are you comparing current RDRAM prices to those SDRAM prices? The fact is that SDRAM has maintained a price advantage over RDRAM for 2 years and it's not going to change. What more of an answer do you want? As far as Micron canning their chipset projects, this is hardly an indication that DDR is dead. If it is, then you must think that RDRAM is dead because Intel canned the Timna project. Let's get back to basics here. There is only one company (Intel) making RDRAM compatible x86 chipsets, or planning to make them, and the chipsets they are planning to make, or have been making, are as follows: Intel RDRAM chipsets82820 (Camino) 82840 (Carmel) 82850 (Tehama) ????? (Tulloch) 82860 (Colusa) That's all there is, at least as far as x86 chipsets go. (Somewhat arbitrarily, both in the lists of RDRAM and DDR chipsets, I've listed only variants that differ in the North Bridge. Consequently, I only leave off the Intel 820e, as it uses the same North Bridge as the 820, and the same with the NVidia 220D and 420D.) Since there are only 5 North Bridges, having one of them (like Timna) cancelled, is a big deal. By comparison, here are the DDR North Bridges, including the Micron varieties: ALiM1651 (Aladdin Pro 5) M1651T (Aladdin Pro 5T) M1642 (?????) M1647 (ALi MAGiK 1) M1657 (ALi Aladdin K7 III) M1667 (?????) M1671 (????? for P4) AMD761 (760) 762 (760MP) 770 (?????) IBM ????? (Summit) Intel82845B? (Brookdale DDR) 82870? (?????) Micron????? (Samurai DDR, Copperhead) ????? (Samurai K7) 4400e (Mamba) ????? (Shogun) NVidiaCrush11 (nForce220) Crush12 (nForce420) Crush17 (?????) Crush18 (?????) ServerWorks????? (Serverset IV) SiS635 (635) 635T (635T) 640T (640T) 735 (735) 740 (740) 745 (745) 750 (750) VIAVT8633 (Apollo Pro266) VT8653 (Apollo Pro266T) VS10-P6 (PM-266T) VT8753 (P4X-266) ????? (P4M-266) VT8366 (KT-266) VS12-K7 (KM-266) You can see that losing 4 DDR North Bridges doesn't mean squat in terms of DDR's support for the x86. In fact, as I've said before, with this many companies competing in the same arena with this many products, it would be totally and completely unbelievable if they all turned out to be profitable and competitive. The mainstream is a very competitive place. That DDR is mainstream is indicated by the fierce competition that occurs there. The cheap price for DDR, as well as the long list of competitors above are strong indications that DDR is a mainstream arena for strong competition. RDRAM, by contrast, is a niche memory type, and is split into 6 different, incompatible, pinouts, and consequently is expensive. There is only one company making chipsets for RDRAM, or even planning to, and so those products are designed to not directly compete with each other. Despite that lack of direct competition, Intel had to kill Timna, and the 82820 is pretty much dead as well. That means that there are no single channel (read "cheap") motherboards for RDRAM, and that is what Dataquest meant when they said last year that RDRAM has been "relegated" to the high end. -- Carl P.S. Glad that you could see fit to contribute to the thread, it's been awfully quiet lately. Why has no one responded to the post where I demonstrated Samsung, Toshiba, and Elpida's dedication to DDR? ( #reply-15962808 ) My thesis is that these companies are mouthing the Rambus line, but selling as much DDR as they can, as it is obvious to them that DDR is the next mainstream memory. What do you think will happen to Rambus' stock price when they announce that they are no longer collecting royalties on DDR? Also, the PriceWatch figures are stuck on yesterday's values with no change. I think they're broken, so I'll skip today's update.
