No, the Pentium D is a dual-core 64-bit CPU. The two cores are the
last few of Netburst architecture, with variants used in both Pentium
4s and some Xeon's. I'm running:
# uname -a
SunOS sensei 5.11 snv_121 i86pc i386 i86pc
On a Pentium 4 with one of those cores in it, and it says:
# isalist
amd64 pentium_pro+mmx pentium_pro pentium+mmx pentium i486 i386 i86
The Pentium 4 also does hyperthreading just fine:
# psrinfo
0 on-line since 09/13/2009 20:23:07
1 on-line since 09/13/2009 20:23:10
So the dual-core nature of the Pentium D shouldn't be a problem.
That said, there are lots of variations on the PD and 64-bit P4, so
the late model high end variant may have some options that a
not-so-high end, but later, PD core is missing.
The next CPU announced after the Pentium D was the Core Solo/Duo,
which was a 32-bit CPU. Intel abandoned the Netburst architecture (it
ran *way* hot for the performance, so I can honestly say that the
above P4 is one of the hottest CPU's intel ever shipped :-) and went
to the Core architecture, losing some capabilities that they later
added back - like 64-bit mode and hyper-threading.pwd
