Pentium 4 having dual core?

So a friend of mine online is having trouble knowing if he has a dual core or not on his system. He copied and pasted the processor spec:

Processor:
Intel(R) Pentium(R) 4 CPU 3.00GHz (2 CPUs)

Is this a P4 with HT being read as 2 CPUs or does he really have a dual core processor. On my limited knowledge I have never heard of a P4 having dual core. Thanks for any help anyone can give.

What is the source for the processor spec?

(I don't mean "uh, my friend is the source dude", I mean "from the invoice" or "from Everest benchmark utility", etc)

Pentium D was the marketing name...but many programs will read the CPUID as Pentium 4 as that was the architecture.

Alternatively if this was a processor spec per Windows or some such then yes the 2 CPU's could very well represent hyperthreading on a single-core P4.

And even further, he could actually have a dual-socket mobo with dual P4's at 3GHz.

The processor spec info is lacking enough specifics to rule out any of these possibilities.
 
It's just a P4 with HyperThreading. A CPU with 2-way SMT is going to show up as 2 processors in Windows. Just like Nehalem shows up as 8 logical processors in Windows.

Just open up CPU-Z and at the bottom it will show, "Cores: 1 ... Threads: 2".

Idontcare, if it was a dual socket mobo he would be running a Xeon processor and it would show up as such in Windows. And AFAIK a Pentium D would show up as a Pentium D 830, or 930. The reason that CPU shows up with just a frequency rating is that back then Intel marketed their CPUs with the family name (Pentium 4) and the frequency (3.0GHz) only. With the 5xx series they started naming them based on random numbers and not frequency.
 
options:
1. It is a dual socket mobo with two seperate P4 chips.
2. It is a single core P4 chip being confused for 2 cores because of HT
3. It is a Pentium D which is just a marketing term for a P4 dual core.

Pentium 4's never had dual socket motherboards, you have to have a Xeon for that.
 
The OP's friend does have a Pentium 4 with HT on. It's one of those Prescott 90nm cores that were nicknamed "Preshawts". 😉

Pentium D in the other hand didn't have HT so rather it was just two HT-less Pentium 4s slapped on a wafer.

Yeah, I could use it for an inblock heater on my truck too.🙂

P4 with HT = 1 physical core to pretend to be 2 "logical" processors.
PD = 2 physical cores

It probably is a hyperthreader like my old P4 533 system. Sometimes marketers for etailers don't advertise things properly which leads to mis-confusion
