1.1 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 processor’s behavior to deviate
from published specifications. Hardware and software designed to be used with any given
processor must assume that all errata documented for that processor are present on all
devices unless otherwise noted.
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.
