$ sudo dmidecode -t processor | grep -E 'Flags:|HTT|Status|Count'
Flags:
HTT (Multi-threading)
Status: Populated, Enabled
Core Count: 4
Thread Count: 4 $ 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.
