These days, some processors aren't what you expect.  (Case in point:  Cyrix
6x86 are 486-class even though they're Pentium-speed.)

To be sure about _any_ system, you can look at the boot messages (or do
"dmesg | more") on a target system and look at the detected processor type.
It'll tell you whether it's 386-class, 486-class, and so on, and that's
precisely the option you need in I?86_CPU for that machine.
