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. http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_11599_11604,00.html >>Sempron/754 might be a little faster than >>it's Socket A version - but that's _only_ >>because of the chipsets for Socket 754 are >>more advanced than Socket A ones.

Yeah, it has been announced a few times, that Sempron/s939 will be available somewhen in 2005 "as market requires": http://www.amd.com/us-en/Processors/ProductInformation/0,,30_118_608,00.html Best wishes, Andrew P.
