s939 Semprons are due out by the end of this year. That will effectively give them dual channel bandwidth, and current Semprons already have SSE3. Soon they will have x86-64 extensions as well, to compete with the 64bit enabled Celeron. The next logical step should be dual core Sempies, which will be fantastic for me. Prices should be significantly cheaper than the X2, while the only thing I'll be sacrificing is a little L2 cache that makes about 5% difference in real world applications. Maybe 10%, since we're talking two cores, but if I'm saving hundreds of dollars, I won't care.
