Hyper Threading lets you simaltaneously do two things at once although its not as efficient as dual core but still its better than single core.

Hi,

Hyper-Threading makes your OS think there are two processors. In some applications it gives a performance boost, and in many it doesnt. Go to your BIOS and check if it is on. Many think HT allows for the processor to do 2 operations at once, it doesn't. It simply changes your processor from a 3.4Ghz at 6 clocks, to 2 3.4 Ghz at 3 clocks each. (or whatever your speed is) If you motherboard is a HT supporting motherboard, and your processor is a HT processor it should be on.

If you want to check do as follows [easiest way]

-Hit CTRL+ALT+DEL
-Click on the performace tab
Where it says CPU Usage history there should be two boxes.
One for each virtual CPU And at full load it should read 50%

You are incorrect. HT does not allow you to do 2 things at once!

Maybe I worded it wrong but it does allow two things to be processed almost simaltaneously(there that sound better).

HT turns a 3.4 Ghz computer a 6 operations per clock into:
2 3.4 Ghz at 3 operations per clock

totally different from what you are saying!

Well so can mine. It simply splits it in half to put it in simple terms and has half of it do one thing, half of it do the other.. The problem then is, on cpu intense things if it "splits" so to say, then you have 2 weaker cores trying to process a intense program and possibly a light program.

Yes I understand the whole clock thing but it still allows for two things to more or less to be done at once.Go to www.intel.com they have a little 3D image there showing how it works.

Edit= I was just trying to give the guy/girl an easy explanation of what it does,if they wanted more detail I would have given it to them I just wasn't sure how advanced they were on the whole concept. :-)
