All Pentiums you'll find yourself buying at least Not Celerons and Ms at least, I don't think, not sure about Ms. And versions before 5xx have HT, they just don't have EM64T like 5xx and 6xx and 8xx.
HyperTransporT Haha. Nah, I suppose HT Technology would make more sense as HTT, but it is what I call it then
Who's to say that Hyper Transport doesn't have a Technology stuck on the end? It could be HTT for Hyper Transport Technology, or maybe the extra T is for the two T's in transport. Just nitpicking the semantics.
Hmmm... ones over 3.0 should have it, I thought 2.8s had it. But they don't point it out in any there, so I'm still pretty sure most Pentiums have it, certainly over 3.0 unless they're 8xxs and not the 840. Don't know why they haven't put it up on their listing.
