Stepping codes of AMD K10 microprocessors

Over time I collected more than 1,500 stepping code/date code combinations for different K7, K8 and K10 microprocessors. I also gathered CPUID information for some of these processors. That data was used to compile a list of AMD K7, K8 and K10 stepping codes. This data was also used to build timetables of K7, K8 and K10 stepping codes. The lists and timetables are not complete, especially lists and timetibles for recently released microprocessors. If you have a K10 processor or microprocessor picture with stepping code not listed below, please use AMD stepping code submission page to submit the code and/or picture.
