[edit] Hyper threading

Hyper threading is always mislead with beeing 2 virtual processors because the processor apears as 2 processors on Operating systems such as Microsoft windows or on the bios's boot screen

The reality is that they duplicated some part of the core's processors such as pipeline,in order to allow the processor to make a context switch in almost no time
