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 stepping codes,
a list of AMD K8 stepping codes
the list of AMD K10 stepping codes (below).
This data was also used to build timetables of
K7,
K8 and
K10 stepping codes.
The lists and timetables are not complete yet, 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.
| Stepping code | CPU Family | CPUID | Core name |

| AAAZB AA | Phenom X4 | F22 (DR-B2) | |
| CAAWB AA | Phenom X4 | | |
