Does setting the Intel Core 2 Duo to present itself as one logical unit bring any benefits?

I have a Core 2 Duo T8100 processor in my laptop and have noticed that there is a possibility in the (Dell) BIOS to set it to be presented as one logical unit instead of two. Would this bring any benefits?

I am probably not using many applications that are demanding and were designed with this multi-core craze in mind at the same time, like these image and video editing software suits, but am running some other demanding applications (that probabably were not designed with the multi-core thing in mind).

And I have actually noticed that when using Street View in Google Maps in Firefox, the CPU usage peaks are usually always somewhere under 50%, so I thought that maybe the second processor unit is not properly used with the current settings (two logical units), though it may be that Firefox being a fairly recent application takes advantage of these processor advancements, so the two logical units settings might not be the cause and the noticeable time taken by sharpening is caused by the GPU or perhaps something else.

So will the setting to one logical unit actually improve performance in the multi-core "blind" applications or not?

 

you will have a big cpu bottle neck if you only use one cpu and it will be a big difference in performance (in a bad way) if you only one core

 

I wouldnt think so as if applications dont use multicores then they jst wont use them, changing it to one logical proccessor means that ur turning one off so that they wont have the chance to use it

 

Well I thought changing the settings to one logical unit, as opossed to one physical unit, means that the processor will present itself as one processor but will still use the 2 cores, with something managing the workload split.

 

You can do a CPU speed test or something first with both the cores working separately and then do a test after combining them or whatever..!! Then compare the tests to see how much is the difference....

What you are trying to say is that both the CPU cores will present themselves as one unified core....but how much will be the clock speed..??
It can't be 2x(the frequency of one core)....because that is kinda contradictory to the whole dual core thing....!!

 

angad's test is a very good idea and I believe it will demonstrate what the others said.

 

Thank you very much. I will try it out.
