Many people tend to confuse Hypertransport
.... unfortunately, both technologies share the same acronym 'HT' (or 'HTT'
, even though they're two completely different things:
is a fast, packet-based point-to-point interconnect which connects the CPU to the rest of the system - basically, it replaces the 'classical' FSB on a K8-platform (Athlon 64/Athlon 64 FX/Opteron).
The Opteron 200/2000 and 800/8000 series can use their additional Hypertransport-links for communication between multiple CPUs.

enables a single CPU to act as two 'virtual'(or 'logical'
It will only offer improved performance if your applications are specifically optimized for Hyperthreading, otherwise there will be little to no benefits - in some cases, you'll actually get slightly less performance when running non-optimized applications.

All AMD 8th-Generation processors (Athlon 64/Athlon 64 FX/Athlon 64 X2/Opteron/754-pin Sempron) use a Hypertransport
-link for communication between the processor and chipset.
Current AMD Processors do NOT
(newer intel processors don't support it anymore either for that matter).
With the introduction of true dual-core parts (e.g. Opteron 265 and higher), Hyperthreading
has pretty much become obsolete.
