[svlug] what is Intel hyper-threading?

I'm writing a short report on multithreading in microprocessors.
In a nutshell, I have
* IBM Power4 and Sun UltraSPARC IV as dual-core processors.
* Sun's upcoming Niagara as multi-core, with multithreading
in the core, and seems to be the most ambitious of
chip multithreading efforts.
* IBM Power5 introduces multithreading within a core; I can't
quite distinguish it from the Sun approach.
I can't figure Intel's "Hyper-Threading Technology"; it
doesn't seem to be multiple cores. Nobody claims it is
emulating multiple CPUs like Niagara. What the heck is it??
