Next Mobile Intel Processors and Platform (Montevina) Due in June 2008
Montevina is the next revision to Intel's mobile platform and will carry the consumer brand "Centrino 2" to distiguish it from the current "Centrino" brand which has encompassed a number of revisions (Carmel, Sonoma, Napa and Santa Rosa).
Six new 45nm notebook CPUs accompanying the release will feature a 1066MHz Front Side Bus with clock speeds ranging from 2.26-3.06GHz. The recently released Penryn processors range from 2.1 to 2.8GHz and offer a 800MHz Front Side Bus. The Penryn processors have not yet been incorporated into Apple's notebook line, despite persistent rumors of an imminent release.
Meanwhile, Digitimes also notes that Intel is planning on releasing 45-nm processors similar to the MacBook Air's custom processor in the 3rd quarter of this year.
