Hyperhreading is different - only one processor that pretends to do

The difference is more a matter of degree. In an HT CPU there is less
duplicated internal machinery. A dual-core CPU has two full CPUs that
operate largely independently. In the current dual-core chips, I
believe, there is a single, shared level-2 cache. The HT CPUs don't
double all of the CPU's hardware, but they still hold two full sets of
the CPU's internal state and a good-sized chunk of the processing
machinery, making possible both (some) concurrent processing and faster
context switching between the processes or threads that occupy those
register sets than on a conventional single CPU.
It seems HT CPUs were just a transitional state between older single CPU
chips and modern multi-core chips.
