    Ask your OS, via some suitable API
    When all else fails, read the instructions.
    If you're posting code, use code tags: [code] /* insert code here */ [/code]

    If you are on Windows, then the info is available under the following registry subkey -

    Code:
    HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0
    I dont know if there's an API that gets this directly on windows......you would have to use the registry APIs to read this entry...there are examples on this board on how to do this
