Intel’s newest roadmap has an unusual addition: Conroe-L. Intel defines Conroe-L as a single core processor, which we assume is based on the Conroe Core 2 Duo architecture. The most recent roadmaps have Conroe-L designated as a Q2’07 component as a supplement to Cedar Mill chips.
Single Core CPU’s are being slowly being phased out now. By the time three quarters roll around, there will be even less demand for them. It looks as though they will replace the lower-end P4 and Celeron D chips, so they will be good for budget PC’s. You can find out more info at Daily Tech.
