I read an extensive article about it in c`t (www.heise.de/ct and /newsticker,
but on german). It was an comparison between Alpha 21264 and IA-64 and other
architectures. The provocative title was "bin schon da" (fr: je suis deja la,
engl: I`am already here). It was an delicous article. I recommend everyone to
read it.

I think some people already made some comments&jobs on it.
