Preface
Preface
This document is an update to the specifications contained in the Affected/Related Documents 
table below. This document is a compilation of device and documentation errata, specification 
clarifications, and changes.
 It is intended for hardware system manufacturers and software 
developers of applications, operating systems, or tools.
This document may also contain information that was not previously published.

Nomenclature
S-Spec Number is a five-digit code used to identify products. Products are differentiated by their 
unique characteristics, e.g., core speed, L3 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.
