This led me on chase, because Intel friends suggested what I said. I haven't looked too closely yet to see the difference between i3/i5/i7, but both i3/i5 do NOT have HT as per ark.intel. If i were to make a guess about the difference between i3/i5, I would go towards the turbo boost capability. But it is late where I am, and I am speaking early tomorrow morning :-), so I will look into it tomorrow, and probably ask a couple of Intel folks here.
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. https://en.wikipedia.org/wiki/List_of_Intel_Core_i3_microprocessors https://en.wikipedia.org/wiki/List_of_Intel_Core_i5_microprocessors 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. -- Len Sorensen
