    In a terminal, type the command:

    cat /proc/cpuinfo

    It will output info about your CPU('s).
    Then you can google the model.

    [edit]

    Or skip the googly bit altogether and log for the string 'lm' in the section "flags".

    If you open a terminal and type

    Code:
    uname -m
    It will tell you what type of processor you have.

    For example on my macbook Pro I typed it and it says "x86_64" this means I have a 64 bit processor.

    this is not completely true. it says "x86_64" because you are using a 64-bit OS. however, you can install a 32-bit OS if your processor is x64. for example, "uname -m" gives me "i686" because i installed a 32-bit OS even though i have a 64-bit processor.

    another way to find out information on your processor is with lshw.
