If you cat /proc/cpuinfo you ought to see something like this:

power management:
That is, there are two cores on this machine's processor, Core 0 and Core 1. Those are your cores.

Something else you can use might be lshw, which will show you a heck of lot of information about your hardware; you'll probably have to execute lshw with
Code:
sudo lshw | more
Generally, lshw will not execute for a non-privileged user.

If you don't have lshw, see http://ezix.org/project/wiki/HardwareLiSter or, perhaps, the software repository for your distribution.

Hope this helps some.

I'm just guessing, but maybe the OP wants to know what kind of core the CPU has.

In tronayne's example, I would find the code number of the CPU in the cpuinfo. It is E7600. Then I would google Intel E7600 and find various pages that seem to be saying it has a "Wolfdale" core (I'm not an expert on this stuff, so I don't know how much information is implied by the name "Wolfdale").

The OP similarly can get the CPU code number from cpuinfo and then get more info by google of the code number along with the manufacturer name (Intel or AMD).
