So I've been looking around, wondering, because my computer says I have 2 Pentium IV Processors, running at 2.6GHz.

I found out that's because of something called Hyperthreading, which is supposed to be built in to all Pentium IV processors.

The idea is to split 1 physical processor into 2 logical processors, so that the unused processor power can be used for a second thread.

However, they say that only 3.06 GHz and above actually use Hyperthreading.

My question to you :

According to online litterature, my cpu is capable of hyperthreading, but not using it.

However, following that logic, Windows, or Everest, or Linux, none of them should be seeing two Processors, if its only using one of the "two Logical processors"

I'm wondering if my computer IS doing hyperthreading or not, and i'm left clueless right now.

If your Device manager sees 2 Processors, then Hyperthreading is enabled on your machine.

Hi
also, if you are running XP home then your OS only supports one cpu and two threads. XP pro supports two cpu's and four threads. So if you are running home, then its sees the cpu's as one cpu and run two threads. If you have pro, then you can take advantage of the two cpu's and have four threads running. As I see it, thats the problem with Windows Media Center - it is XP home so if you have system that has dual CPU's, you don't really get the benefit (as far as I have found in my reading)...doc
