I'm pretty sure that these days i386 *arch* is usually compiled for the >= i686 *processor*. This is certainly the case for Ubuntu: https://help.ubuntu.com/12.04/installation-guide/i386/hardware-supported.html
"However, Ubuntu precise will /not/ run on i586 or earlier processors. Despite the architecture name "i386", support for actual 80386 processors (and their clones) was dropped with the Sarge (r3.1) release of Debian^[2 <https://help.ubuntu.com/12.04/installation-guide/i386/hardware-supported.html#ftn.idp3258160>] . (No version of Linux has ever supported the 286 or earlier chips in the series.) Support for i586 and lower processors, as well as for i686 processors without the cmov instruction, was dropped in Ubuntu 10.10. Most i686 and later processors are still supported^[3 <https://help.ubuntu.com/12.04/installation-guide/i386/hardware-supported.html#ftn.idp103528>] ." i686 started with the Pentium Pro and Pentium 2 for Intel and IIRC with the Athlon for AMD.
