There are only a few i3 models that have 4 actual cores.  Almost all are
2 core with hyperthreading.  The i5 on the other hand was almost always
4 cores (now 6 cores on the latest generation) without hyperthreading.
There were a few low end models that were exceptions and were configured
like the i3 with 2 cores and hyperthreading.  So for the i3 hyperthreading
was the norm and for the i5 hyperthreading was the exception.

At the high end the i7 always had hyperthreading until the latest
generation where some no longer do (the i9 does though).  Apparently 8th
gen i7 with 6 cores and hyperthreading is replaced by 9th gen i7 with 8
cores and no hyperthreading.
