Listing number of cores #133

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
I am running this utility on a core i7 720QM intel CPU and Intel Q57 chipset 
Dell Latitude notebook. I have Win 7 Prof OS running on this machine. I 
downloaded the latest software (0.2.0 beta) from your website and saw that 
every thing listed was correct for except the nos. of cores. 

The nos. of cores it listed was 4 while actually it is core i7 CPU. So what 
exactly I am missing?

You do only have 4 cores. While some programs may display 8 cores, that's 8 
logical cores.

Your CPU has Hyperthreading, which is a form of multithreading within the 
processor core. Each real core has 2 HT cores, which results in the 8 logical 
cores.

The only thing we do lack I guess is displaying the load on the logical cores 
rather than the physical ones; temperature and such are impossible to get, 
since they don't really exist.

If the above is still unclear to you, you should check out some articles, like 
http://en.wikipedia.org/wiki/Hyperthreading for example :)
