Hi Jdaasoc; Re: "2 nsec would be reduced to 1.6 nsec. That's what I mean by scability."

So to you "scalability" means increase in frequency. Are you aware that DDR came out in graphics just one year ago, and at only 200MHz? Are you aware that the new graphics chips from Samsung are now at 500MHz, a factor of 2.5x higher in only one year? Are you aware that DDR-II is expected to reach 800MHz point to point? It seems pretty clear to me that DDR has scaled much, much, much faster than RDRAM. If RDRAM had scaled 2.5x in one year off of the original 600MHz parts, we would be have chip makers currently sampling 600 x 2.5 = 1500MHz parts. Instead, we have word that someday they are going to sample 1066MHz. That is lack of scalability, compared to DDR.
