The "turbo-limit" is the maximum opportunistic processor
speed, assuming no electrical or thermal constraints.
For a given processor, the turbo-limit varies, depending
on the number of active cores. Generally, there is more
opportunity when fewer cores are active.
Under the "-v" verbose option, turbostat would
print the turbo-limits for the four cases
of 1 to 4 cores active.
Expand that capability to cover the cases of turbo
opportunities with up to 16 cores active.
Note that not all hardware platforms supply this information,
and that sometimes a valid limit may be specified for
a core which is not actually present.
