Has this intel pc got a hyperthreading cpu in it?

[Bubo]

Forgive me but I currently know sod all about Intel cpus having used nothing but AMD since the old pentium 2 days. I use a pc at work for finite element analysis, according to the system details it uses a 3.06gig pentium 4 cpu. Is there a simple way to tell if this cpu is at all multiprocessor capable, which I believe is what hyperthreading means* Its running windows 2000 btw.

*see comment about knowning sod all about intel cpus if this statement is bs.

Hyperthreading means that your CPU acts as if it was two processors rather than 1 processor. You can check if you have hyperthreading by pressing CTRL+ALT+DELETE and then clicking the performance tab. If you have two graphs for your CPU then you have hyperthreading. If there is only 1 graph for your CPU then you have no hyperthreading.

Edit: Just to clarify, hyperthreading does not mean your system could take two physical CPUs in it. (Infact unless you have a server board its unlikely that you can run SMPs).

Am I right in thinking that it will only show up as two CPUs if hyperthreading is enabled in the BIOS - or am I talking out of my arse

You can also check the CPU with CPU-Z http://www.cpuid.com

The 3.06 Ghz 533 FSB was the only 533 model that was ever given hyper-threading if I recall correctly.

No, you're talking out of the correct cavity It will indeed only show as two CPUs under task manager if enabled in the BIOS.

PS. You should only use HT under WinXP or later, not in Win2000 according to various sources (something about the precise way that HT is recognized under W2K vs. WXP).

Phew

I was thinking about the Win2K thing as well but wasn't too sure about it so I decided to keep shtum about it in the hope that someone else would mention it - Well done

Yes according to task manager there are two cpu performance windows. I set Abaqus to use two cpus and it didn't balk at it, apart from using up 2 liscences instead of 1. Will have to do a benchmark to see what real difference it makes. Cheers.

So in XP do you get the option to assign processes to different logical cpus, cos there doesn't seem to be any options for that in win2k task manager. And you wouldn't believe the hoops you have to jump through here to get anything upgraded, eg win2k to winxp.
