oldfart... not necciserally. Rambus proves itself quite useful w/ the p4... how else do you think that q3a is able to perform as well as it does on a p4 (rambus + qdr bus). One good thing that rambus is great at is memory throughput, it kicks DDRSDRAM's ass in that department. Its major flaw is latency however, and that is where DDR excels. Its all a matter of perspecitve and what types of applications you use. Myself, I would never touch rambus, but i know there are some viable uses for it, and who knows, in the future... they may be able to reduce the latency and kill off DDR. I dont really like rambus, these are just my thoughts on the technology.
