The kernel already does this at boot time, and show the results, e.g.:

CPU: Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz (3391.68-MHz 686-class CPU)
  Origin="GenuineIntel"  Id=0x306a9  Family=0x6  Model=0x3a  Stepping=9
  AMD Features=0x28100000<NX,RDTSCP,LM>
  AMD Features2=0x1<LAHF>
  Structured Extended Features=0x202<TSCADJ,ERMS>
  TSC: P-state invariant

Unfortunately the kernel does not expose this information via any
sysctl, so some time after booting it may have "scrolled away" in

In that case, you can use either the misc/cpuid or the sysutils/cpuid
ports to show this information, and even quite a lot more.
