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 (see below) and K10 stepping codes.
This data was also used to build timetables of K7, K8 and K10 stepping codes.
The lists are not complete.
I doubt they will ever be complete, though I'm going to look for missing
stepping codes and CPUIDs, and I will certainly add more data in the
future. If you have a K8 processor or microprocessor picture with
stepping code not listed below please use
AMD stepping code submission page
to submit the code.
