nach einigen Seiten des Durchlesens hab ich folgendes herausgefunden:
Das Stepping (Core-Stepping) ist eine Zahloder Zahlen-Buchstaben-Kombi , welche die Revisionsnummer einer CPU wiedergibt, sowohl bei AMD als auch bei Intel. Zu finden als letzte Zahl der CPUID.
Ich glaub, was die Proggis CPUINfo bzw WCPUID da ausgeben, sind die Stepping-Nummern der Prozzis.
(Tweak-XP zeigt übrigens dasselbe Stepping...).
Ich denk mal, ein Steping hat immer auch einen eigenen Code auf der DIE, weshalb dann immer von Agoga, Agoia usw gesprochen wird...(reine Vermutung...)
z.B.
Table 3. CPUID Values for the Revisions of the AMD Athlon™ Processor Model 6
Revision CPUID
A0 660
A2 661
A5 662

CPUID Instruction Overview
Software operating at any privilege level can execute the
CPUID instruction to identify the processor and its feature set.
In addition, the CPUID instruction implements multiple
functions, each providing different information about the
processor, including the vendor, model number, revision
(stepping), features, cache organization, and processor name.
The multiple-function approach allows the CPUID instruction
to return a complete picture about the type of processor and its
capabilities—more detailed information than could be
returned by a single function. In addition to gathering all the
information by calling multiple functions, the CPUID
instruction provides the flexibility of making only one call to
obtain the specific data requested.
The functions are divided into two types: standard functions and
extended functions. Standard functions provide a simple method
for software to access information common to all x86
processors. Extended functions provide information on
extensions specific to a vendor’s processor (for example, AMD
family processors).
The flexibility of the CPUID instruction allows for the addition
of new CPUID functions in future generations of processors.
Appendix A, “CPUID Instruction Definition,” contains a
detailed description of the CPUID instruction.

Using CPUID Functions
When software uses the CPUID instruction to identify a
processor, it is important that it uses the instruction
appropriately. ......
