In reality, the i686 was introduced in 1994. Almost everyone
implements the i686. And i686 has a _lot_ of benefits.
Anything superscalar is almost always i686 compatible (or
close to it).
i586 is clearly genuine Pentium only, at least
performance-wise, and has hacks that run _poorly_ on newer
i686 processors. Pentium had a lot of bugs, because it was
Intel's first x86 superscalar atempt.
i486 is definitely the "next step down" -- and it's a damn
big step. ;->
