As I mentioned at CMG 2008, and also in my Guerrilla Boot Camp classes, it's important to keep your eye on the various twists and turns in the technology marketplace, so that you are not broadsided when it comes to things like server procurement. One example I referred to is the very aggressive microprocessor technology roadmap that Intel is pursuing; something they call "tick-tock".
Although I'm not tracking these events as closely as I was last year (when Intel was racing toward 45 nm parts), it looks like AMD microprocessor fabrication is essentially 1 yr behind Intel. One way this leapfrogging occurs is due to full automation. Intel can go from lab to fab essentially in one shot by uploading their lab "recipes" into the production chip fabrication line. They claim to have 32 nm working in the lab already and are planning to ship parts in 4Q09.
Update: In spite of that, Intel 4Q08 profits plunged by 90 percent.
Update: In related news, world-wide desktop PC sales have taken a pounding.
