Nomenclature
S-Spec Number is a five-digit code used to identify products. Products are differentiated by their
unique characteristics, e.g., core speed, L2 cache size, package type, etc. as described in the
processor identification information table. Care should be taken to read all notes associated with
each S-Spec number
Errata are design defects or errors. Errata may cause the Intel
®
Pentium
®
processor’s behavior to
deviate from published specifications. Hardware and software designed to be used with any given
stepping must assume that all errata documented for that stepping are present on all devices.
Specification Changes are modifications to the current published specifications. These changes
will be incorporated in the next release of the specifications.
Specification Clarifications describe a specification in greater detail or further highlight a
specification’s impact to a complex design situation. These clarifications will be incorporated in
the next release of the specifications.
Documentation Changes include typos, errors, or omissions from the current published
specifications. These changes will be incorporated in the next release of the specifications.
