(In reply to dewayne from comment #2)
Term hyperthreading has very narrow meaning, it is only applicable to Intel'
CPUs.

FreeBSD systematically uses term CPU as an execution agent that has independent
ISA state.  RISC-V calls them harts.

Core is the single execution engine that can provide several OS-visible CPUs,
where CPUs share some execution resources, and which cannot be 'split' into
smaller chips.  At least this is the terminology of CPU vendors.

Sysctls descriptions should not be an educational resource.
