i7 Multithread/core

[Nate75]

Hi.

I have just setup my first i7 machine.

I am running an app which is using 12% of the CPU as rated in Windows 7 64bit Enterprise Task Manager.

Am I right in thinking this is because the app is only using one thread of a possible 8?

Previous I assumed that if an app has not been built to support multi core then with a quad core I would hopefully see 25%ish of the CPU being used when running an analysis app for instance...?

I am not sure how the multithreading works with i7...

Any advice appreciated, thanks,

N.

Basically, yes. The application is single threaded and is therefore only maxxing out one core on your i7 CPU.

However, the i7 is a pretty intelligent CPU and it performs various tricks like pipeline sharing between the cores. So what you see in Task Manager is not necessarily what you are actually getting.
