Intel® Processor Identification Utility
CPU Stepping field result is different than expected

The Intel® Processor Identification Utility contains a field on the CPUID Data tab that reports the CPU Stepping information for the tested processor.  This field is part of the CPUID string, and reports the actual manufacturing stepping value of the processor in hexadecimal form. 

The CPU Stepping value is not synonymous with Core Stepping, as reported in other locations such as the Processor Spec Finder website and specification updates.  The Intel Processor Identification Utility does not report Core Stepping values. 

The Processor Spec Finder website provides both CPU Stepping and Core Stepping information for each processor sSpec referenced.
