Yeah, it appears I got a wrong idea from some poor
article. As a matter of fact, Sempron/sA is based
on Barton core, while Sempron/s754 is a K8 sister.
The latter has an on-chip memory controller and
SSE2 instruction set supported. They are pretty
same in all other aspects though, and I still
suppose the perfomance margin is negligible.

Yeah, it has been announced a few times, that
Sempron/s939 will be available somewhen in 2005
"as market requires":
