HT != Dual core ;)

Yes I know, and...?

I disagree....
Intel's HT (HyperThreading) is _only_ similar in the regard that it may
appear to the OS as a 2nd 'logical' virtual core. I do not know the
Linux kernel (nor the OS) well enough to say exactly how it will/should
see a DC CPU.

DualCore CPUs (whether they're AMD64 X2, or Intel Pentium D) are 2
physical cores on 1 CPU Die (Chip). Perhaps you both already know this,
I'm just trying to clarify for other readers....who may misunderstand
the info given. HT tech is no such beast.

AFAIK - Intel doesn't make the P-D class (820/830/840), that *also* do
HT; that would be left to the 840EE, P4660, and P4EE versions, which
would appear as 4 Logical cores to the OS.

"The major differences between the Pentium Extreme Edition and the
Pentium D is the Pentium Extreme Edition's support for hyper-threading
(HT Technology) and support for clock-multiplier-based overclocking"
---------------------------------


Concerning Temps (from the same article)
----------------------------------
"Note that the fastest Intel Pentium 4 and Pentium 4 Extreme Edition
processors are a good bit faster than the Pentium D and Pentium Extreme
Edition processors. The Pentium D and Pentium Extreme Edition
processors run hotter than single-core Prescott chips (after all, they
contain two Prescott cores in one processor), and reducing the clock
speed helps keep the thermal load on the system to a maximum of 130
watts."

ugh;
Just to try and further clarify...
Intel's "Pentium Extreme Edition Model 840" is a DualCore *and* does
HT, *and* has an unlocked multiplier. The P*4*EE and the P*4*660 are
/not/ DC, yet are HT enabled. I'm just not certain I'd classify the
PEE840 as a Pentium-D, but it probably should be. When trying to sort
through the nonmenclature mumbo-jumbo...note that *4* is the operative
difference(s).
