I would say the performance gains on an AMD cpu will be minimal. Simply
because most of them either have no application to A64's (mwait, monitor),
are already pretty much present in A64's through 3DNow (haddps, hsubps, the
complex arithmetic instructions whatever they are, but not their
double-precision counterparts), or are in areas where A64's aren't hit as
hard as the P4 (lddqu). Of course, it's always possible that AMD will manage
to pull off a significant performance boost, but my money would be on the
gain being in the sub-5% level, if anything, in most apps.

I certainly wouldn't put off buying a CPU just because it doesn't have SSE3.
The better reason to wait for a SSE3-capable A64 is that they will be the
next core revision, which is supposed to have a few bug fixes and
performance tweaks compared to the current rev D cores (abd hopefully
overclock a bit better too ...).

Thanks for the reply Michael. I believe you are right. A small performance
gain would probably not be worth the wait.

Do you think the new cores will be optimized for DDRII?

Does anyone know if the eventuall switch to support for ddr2 will mean
another socket change as well?

Heard a rumor of a socket 900.

really? I had heard that if / when amd went with ddr2 that it would mean an
increase in the number of pins!

Last I read Opteron will get a new socket in 2006, not sure about the
Athlon 64.
