Is PCV-RZ221 really dual processor?

[MartinWink]

My Vaio RZ221 reports through all of the Windows system information tools and TaskManager that it has dual CPUs, but I've never seen it reported anywhere in the sales blurb that I was getting a dual processor machine.

Does everyone's machine report the same or have I somehow got Windows XP rather confused?

It definately doesn't have two processors - I fear you have confused XP

Only home-made PCs seem to have dual CPUs, though some servers do, but they're expensive.

Thanks for the prompt replies guys...

I followed clues from the BIOS messages, and did a search on Hyper Threading. Turns out the Intel processor itself has two logical processors inside one physical chip.

Yep, this hyper threading is pretty useful.

I never thought of that - thanks for letting us know. I haven't used an HT computer yet although I do have a very nice dual Xeon at work to play with
