Solution 1:

Try this from the terminal or execute as needed:

system_profiler|grep Processor

Sample:

> dmourati$ system_profiler|grep Processor
>       Processor Name: Intel Core 2 Duo
>       Processor Speed: 2 GHz
>       Number Of Processors: 1

Solution 2:

A faster way then the previous post:

system_profiler SPHardwareDataType | grep Processor\ Name

That limits it to only scanning the hardware, which is faster than scanning the whole system.

You can also change the first command to system_profiler -xml SPHardwareDataType if you want to read it in as XML and parse it that way (which should be more stable if the output changes from version-to-version.
