Ali,

I am only one person and cannot keep responding to each and every bit of information about RDRAM vs. DDR and much of it misinformation. Whenever I ask some questions I always receive the answer "future DDR product launches" vs. "past non-optimized RDRAM chipsets." Always. Never a straight forward answer.

Want to see performance advantage of RDRAM over not just SDRAM but also DDR, and this is on a CPU that is no where near as fast as INTC was introducing last week, much less next year, where more and more of RDRAM's capacity will be utilized is:

And this is just off the top of my head. Relevant quote:

Dual RDRAM channel pays off for the i850 chipset; landing the largest memory bandwidth number we have ever seen. Compared to the i815E running a 133 mhz bus, Intel's quad pumped 100 mhz bus delivers more than three times as much memory performance. Even AMD's newly released 100 mhz double-pumped DDR platform can't keep up and scores less than half the bandwidth.

So, again I say, why don't you ever give a straight answer to such questions. Its always future chipsets, or references to the i815 which is not even relevant as the above mentioned AMD chipset was optimized for DDR in a way that the 815 or 820 was not for RDRAM.
