To my knowledge, cpuctl only uses the family and model number as
returned by cpuid to come up with a CPU name. Intel pretty much
abandoned that a long time ago, opting instead for strings, such as the
one you see further down in the cpuctl identify output. Extended family
and model numbers have been kept up-to-date though afaict, so cputctl
could use those instead.

This 'misidentification' is entirely harmless though.
