This is all based on http://www.dailytech.com/article.aspx?newsid=10875 plus the wiki article on Intel mobile chipsets. Basically, we are given the roadmap for Montevina and the slight processor refresh that comes with it (just like the Santa Rosa refresh we saw). What is nagging at me is that Intel is known for wanting to push out old technology quickly as of late (phasing out the merom for penryn and santa rosa for montevina as soon as it hits), so why in the world would it launch Nehalem with Calpella chipset 6 to 8 months later? From the specs of Montevina, its obvious it won't support Nehalem's quickpath, so it pretty much mandates a new chipset only half a year later when the first mobile Nehalems roll out. The only way to get around it is if Nehalem is delayed and they aren't spilling the beans yet. I tried to contact the dailytech authors about this, but they've not replied. In fact, we still don't know what the difference between the 2.53ghz with 25w and 25w TDPs are. Anyone else know more about this?
