2 CPUs? Glitch?

Right presently I'm using a Pentium 4 Mobile HT 3.21 GHz, it's of course is a single core. Anyway, Windows (Dxdiag and the chore manager) keeps saw it's '2 CPUs', It shows up as Intel Mobile Pentium 4 (2 CPUs). Is this a glitch or something?

2 CPUs? Glitch?

Hyper Threading (HT) is a technology of intel processor to make it looks as if it have 2 processor. It doesn't have 2 cores, lately duplicate certain parts contained by the prefetch stages.



Anyway, the effect is that the operating system will see two processor, and so it can dispatch multiple threads to each processor it see. The HT CPU improve its show by being competent to fetch 2 different threads simultaneously.



BTW, its not a glitch. It's suppose to be that way =)
The answer above is correct. I aversion it and turn it off when I have such computers. It does help for some/most applications, but is discouraging sometimes. The setting can be changed in the bios whether to use HyperThreading. At boot up formerly Windows even starts its work, you should be prompted to press F2 or F8 or something else to enter the bios.
