I haven't seen any tests, yet I've seen Sempron/Socket-A
in action and it was impressive. I also have Athlon 64
and Athlon XP pc's at home and I don't think K8 is
so superior. In non-sse2 non-very-memory-intensive
applications it performs better, but not "turbo-charged".

Besides, AMD is pricing Socket-A Semprons even higher
than s754 versions. Considering the fact that s754 is
clocked lower than sA of the same PR, it can be hard
to determine the speed difference.

Anyway, I really think there's nothing for us to
argue about :) Gareth is staying with s754 and we
should be glad for him :)


Very best wishes,
