Yea, but Hyperthreading is a nice idea that is still somewhat irrelevant at this stage. Even with dual-cores on the horizon there has is lots of optimizations to do before any of this power is utilized.
More relevant now is Hypertransport, which for some reason AMD doesn't brag about as must as Intel does for Hyperthreading. Hyperthreading and hypertransport are vastly different beasts. Hyperthreading creates two "virtual" processors on a single CPU. Here is a good description of hyperthreading: http://en.wikipedia.org/wiki/Hyper-threading.
Hypertransport, on the other hand is a chip to chip transport. It is a serial interface that makes the bits go faster. It is basically the bus logic and thus far too technical to be interesting to the marketing types. Where hyperthreading performance can be described by marketeers as making your app go fatster, hypertransport will speed up everything, but it is difficult to quantify and thus marketeers can't sell it. Just my 2 cents. Thanks Brian
