You are right! AMD licenced HT-Technology from Intel.
AMD Dual Core CPU's uses this to fake a HT-CPU.
"Fake"? Hyperthreading is just a fancy word for what AMD's "Dual Core"
describes much better: these CPUs have multiple cores, i.e. instruction
handlers, that share the integer, floating point etc. units. The idea is
that, since in a conventional CPU all but one of these units are idle at
all times, multiple cores could make better use of the CPU.

I dont want to contradict!
the german wikipedia writes (http://de.wikipedia.org/wiki/AMD_Athlon_64_X2):
"Der Athlon 64 X2 gibt sich als Hyper-Threading-fähig aus und kann dadurch von
diversen Optimierungen profitieren,..."
"The Athlon 64 X2 masquerade as hyperthreading capable to benfit from
hyperthreading optimizations."
I didnt recheck this information with AMD official papers. Now I did and I
could not found anything about ...
I wrote the author of this sentence to get his source of information.

FWIW, Hyerthreading is not the same as Dual Core. HT still occurs on a
single processor core, it's the branch prediction and the pipelining
that lets a single core act more like a dual CPU. A dual core system
has two sets of pipelines, instruction sets and branch prediction
registers, in effect the exact design of a two CPU system on one die.
Hyperthreading is sort of a halfway point between a single and a dual core.
