>Rule of thumb: On a desktop, if you have an i5 you do not have Hyperthreading. All i3s and i7s do have Hyperthreading, as do new Kaby Lake Pentiums (G4560, 4600, 4620).

Hmm...either this statement is wrong or this desktop /proc/cpinfo is wrong:

    $ grep -E 'model|stepping|cpu cores' /proc/cpuinfo | sort -u
    cpu cores	    : 4
    model           : 94
    model name	    : Intel(R) Core(TM) i5-6600 CPU @ 3.30GHz
    stepping	    : 3
    $ grep -q '^flags.*[[:space:]]ht[[:space:]]' /proc/cpuinfo && echo "Hyper-threading is supported"
    Hyper-threading is supported

Intel's product spec page[1] lists this CPU as not supporting Hyper-Threading so I'm a bit puzzled as to why the ht flag is present.
