once there was a very cool tool to identify AMD processors.
It worked this way:
You had to paste the 3 code lines from the processor label into the appropriate fields in this tool and then it calculated all possible info out of these values. So it did not attempt to scan it via software from the CPU but it needed the user to provide the information.
This way it revealed such cool info like stepping, production week, thermal power and so on.
Sadly I forgot its name and can't find it anymore.
Does anyone of you know it and can point me to it?
