"A so called product ID or OPN description is on each AMD Phenom and Phenom II CPU, but this product ID is not really easy to understand without studying several datasheets. On the new AMD Phenom product ID guide simply select the description of your processor over the drop-down fields or type it directly into the new OPN field. Then you will see the technical data and processor description below in the virtual CPU. The service is of course free available over the web and it is also possible to control this interactive guide directly with OPN data over online shops, forums, or web pages."
