SMP and "Dual Core" are different. The current range of AMD 64s already have the capacity for "Dual Core" but they "extra" CPU isn't built into them. This is not hyperthreading as implemented in P4s.
In fact dual core will primarily use the hypertransport bus between cores, but will also support slower hyperthreading.
All you have to do is set processor affinity to take advantage of it, run your OS on one core, your game on the other core.
Agreed though largest speed increases will need apps that are aware.
Saying that the first desktop dual core cpus will be based on whatever AMD FX5? CPU is current. Even without being able to take full advantage there will still be a measurable speed increase.
There is absolutly positively no truth to the rumour that AMD processors are cheaper, faster and better than Intel.
