I resently clicked on Task Manager on my HP Mini-10 and under Performance I saw TWO chards for CPU Usage. I then went to control panel - System - Hardware - Device Manager - processors and there were TWO separate listings for the INTEL Atom N270. I have since checked several other netbooks and I see the same thing. Is this a bug in the Windows XP Home for netbooks, or something else?
Thanks, curious in VA.

I'd guess it looks like this because Atom uses Hyperthreading, so one core looks like 2 in that respect. Not sure if procs with multithreading actually look like multi-core in windows, so not positive...

^Yes. A Pentium 4 with HT would show up the same way in device manager. Sorry to burst your bubble but the N270 is only a single core Atom. There is only one dual core Atom available (the 330) and I don't think Intel is allowing it to be used in netbooks yet.

More than anything else, Iwas really PUZZLED! The hyperthreading explanation seems reasonable. No bubble burst, I "knew" that the N270 was single core, I just did not understand why both Task Manager and Device Manager were reporting TWO processors.
Thanks for the explanation!
