Hyperthreaded CPU has some additional hardware resources that allows it to 
pick the instructions to dispatch to the execution units from two (or more) 
separate threads. This is supposed to result in better utilization of the 
available execution pipelines.
Athlons and Durons are superscalar but not hyperthreaded, they handle only a 
single instruction stream at a time.
