An Intel roadmap that surfaced at the Intel Developers Forum 2008 shows that Intel plans to bring the next generation Atom processor to market in Q3 2009 -- roughly a year from now. PCWatch reports that the new Atom will carry the codename Pineview and will be offered in both dual-core and single-core versions.
Today's Atom CPU is based on the Silverthorne micro-architecture, the next-gen Atom will be based on the Lincroft micro-architecture. The biggest difference between the current Atom and the one we should see this time next year is that the Pineview Atom will integrate a GPU core and a memory controller into the die or chip package. Exactly how the GPU core will be integrated is unknown. Roadmap slides at PCWatch show a "1?" for the number of die(s) -- it seems even Intel isn’t sure how the GPU core will be packaged with Pineview at this time.
