An article explaining how CPU works?
Does anyone know of a good article explaining how a CPU works? It must be really detailed, and it's good if it explains differences between different types of processors (pentium, amd etc) and also says something about 64-bit architecture (x86_64, ia64).
I've seen several articles (like the one from HowStuffWorks.com and wikipedia.org), but somehow they were not exactly what I was looking for.
Any suggestions on where I can find such an article?
