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.
