[WIN7] Task Mgr shows dual core CPU, but is it really?

I was working on an upgrade job to Win7/32 with a Pentium 4 540J 3200MHz - Prescott. According to Task Mgr. it shows up as a dual core and there are two separate performance windows. According to Wikipedia and other sources (CPUID) it is a single core. Anyone have any ideas what's going on with Task Mgr or are all the other things wrong?

No Problem there...

The P4 540j processor uses Hyper-Threading, so it shows up as having TWO (virtual) cores on Motherboards that support it...

If You're Unsure, "RTFM"... If You're SURE, "RTFM" Anyway.

Awesome. Thank you very much!

Technically it has 1 full core + a second execution pipeline
The performance isn't quite up to dual core but its pretty good.

that's the same tech that i7's use (quad core + hyper-threading = 8 performance graphs)

i3 = dual core + hyper-threading
i5 = quad core w/o hyperthreading
i7 = quad core + hyper-threading (or hexa-core + hyper-threading for the top end ones)

then the high end xeons = Oct-core + hyper-threading (ie 16 graphs per socket)

Does that even exist?

Oh sure. There are much bigger servers out there. This particular one is just a simple Dell PowerEdge r710. It has 2 x Xeon x5650 processors in it, which are 6-core w/hyperthreading. That's why it reports 24 cores to the OS.

It just looks so weird in Task Manager. Tons of tiny tiny squares with all that extra grey space not being used. That, and I've never seen that many before veing disaplyed in Windows Task Manager. Cool stuff!

If you want to see crazy imagine the following

a DL980G7 (because the G8 isn't out last I looked)
with 8x 10core HT xeon's

then load windows datacenter server on it
it'd have 160 little graphs

Now if someone has the money to buy that server let me know I'd like to check it out in person.

That DL980G7 I mentioned is available with up to 2TB of ram

can you imagine 160 effective cores and 2TB of ram? /drool

Just having a tough time thinking about what I'd use just one of those for. If I had several and could vmotion machines between hardware, yes, but a single box that big is way overkill.

Well just leave laptops out.

The mobile chips just fuge things up.
