in /usr/src/sys/i386/conf/NOTES we can read :

#
# You must specify at least one CPU (the one you intend to run on);
# deleting the specification for CPUs you don't need to use may make
# parts of the system run faster.
#
cpu             I486_CPU
cpu             I586_CPU                # aka Pentium(tm)
cpu             I686_CPU                # aka Pentium Pro(tm)
