Carl, re:<both i820/RDRAM and i815/PC133 are choked by the FSB, which limits memory accesses to 1033MB/sec>

RIGHT! I forgot that. Do you agree that comparing PC100 to PC133 performance on the same manufacturers chipset in non-overclocking mode, then doubling or tripling the difference, should be a good bogie as to the performance improvement achievable with PC2100, assuming that the FSB is fast enough?

<Both are choked by the FSB, which limits memory accesses to 1033MB/sec>

This is incorrect. There is no part of any
application-based benchmark that gets even
close to half of this 1066 MB/s limit.

I thought that we all here agreed lately that the
latency is the most important factor, at least for
current generation of non-prefetching codes.
Both memories have about identical latency,
both systems have 133MHz FSB,
hence the results are about the same.
