Sylvester, I certainly would like to see any benchmarks that disprove the above. Thanks. You posted the benchmarks yesterday- i815/PC133 consistently beat i820/PC800. The only rational explanation is that i815/PC133 has lower average latency than i820/PC800. Scumbria

Sylvester, One of the great misconceptions that people have about CPU's is that you can get more work out of them by running more than one application. Running multiple apps at the same time stresses the system, and rapidly becomes inefficient. While it may be true that high bandwidth memory helps mitigate the problems associated with an overloaded system, the most efficient solution is to run the apps serially, rather than in parallel.

Question regarding latency that was asked of Avo Kanadjian: (QUESTION) FiringSquad: Everyone says that RDRAM has latency issues. How does RDRAM latency compare to SDRAM? Doesn't RDRAM have a significant delay as it switches between active and standby modes? (ANSWER) This is another misconception. You have to make a distinction between component level and system level measurements. In the worst case when the memory system is underutilized, Rambus system latency is comparable to that of an SDRAM system. When the memory system is heavily utilized, Rambus' high bandwidth architecture that efficiently supports concurrent memory transactions results in far better latency than SDRAMs. RDRAMs supports 4 power modes that allow performance and power consumption to be optimized. Between the two highest performance modes called active and standby there is no significant delay.
