X86 cpus' Guide - From 8086 to Core i7 !

Cpus are really fascinating for computers fans : it is central piece of every PC, and so, the most important.
However, this enthusiasm for cpus faslty disapear once they're a little old : last released cpus are admirated, but oldest are subjects of jeerings. Because, the symbol of power that cpus represents, grows old very bad.
And that's why, there are only a few people who collects cpus, unlike stamps, coins or even beer bottle caps...
Nevertheless, it is far from being without interest, because of large number of different models, because of their difference and because of their very fast evolution : the oldest cpus, Intel 4004 was released 35 years ago, and the first x86, the 8086 in 1978, but they have quite no common points with the latest Pentium 4 or Athlon 64...

This site is trying, on the first hand, to enumerate all different existing models of x86 cpus (see Search menu), to make you discover their history, their characteriscs and their visual or electronical specificities (see History menu), and on the other hand to put my own collection online, with now 4527 different cpus.
