HyperTransport is just AMD's term for the type of bus connection it uses.
It's not at all the same as Intel's "HyperThreading", which pretends to be
two cpu's.
Don't worry about it. Although hyperthreading sounds great on paper, the
reality is that it doesn't really produce that much extra performance in
real world stuff. And in some cases, it'll actually reduce performance. It
exists mostly because the P4 was so poorly designed.
If you really want more than one cpu, AMD will be comming out with dual-core
chips in the not too distant future. The AMD64 was specifically designed
for that. (Where as Intel is having to try and retrofit it into their
future P4's, now that they admit they can't get them faster than 4ghz.)
