too many processors listed in /proc/cpuinfo

Postby MitschuMyy on Sun Nov 03, 2013 6:31 am

Hi!
I've been using Linux Mint for a while and it has always worked fine for me, but finally I want to learn a few things about the operating system.

One question I came across when trying to scale down my cpu frequency and governor directly after booting (which hasn't worked yet, if you have any experience with that please look at the thread: http://forums.linuxmint.com/viewtopic.php?f=49&t=149119) is, why /proc/cpuinfo lists 4 processors, if the listed processor Intel(R) Core(TM) i3 CPU M 370 @ 2.40GHz is listed on Intels site with only two http://ark.intel.com/products/49020/.

Is there a harmless explanation to it or is there some configuration or something that might be wrong?

Greetings Michi

Linux Mint is funded by ads and donations.

/proc/cpuinfo lists the number of threads which can be executed, not the number of physical processors. Threads are the independent execution paths which can be executed by the processor. See this wikipedia article for more information: http://en.wikipedia.org/wiki/Multithrea ... chitecture)
