System profiler only showes 2 cores

[thomask123]

Hi,

I just received my new MBP with i7 processor.

What I understood is that the os should recognize 8 cores because of the 4 cores with multi threading. The system profiler however, only shows two.

Was I misinformed or is something up with the hard/software?

Thanks!

You have been mis informed.

They have two physical cores, and each core has a "virtual" core.
Which equals 4 cores. The processor is a dual core processor... just with a fancy feature.

And only the 2 physical cores will come up on the system profiler however if you have iStat it will show 4.

Apple does not sell a quad core laptop. The desktop i7 processors are quad core, but not the one that Apple uses in the MacBook Pros.

The i7 in the MacBook Pro is known by the codename "Arrandale" is a dual-core part with HyperThreading; by that there are only 2 physical cores for a total of 4 logical cores.

Sorry if this is what you did not want to learn.
