Information on non-boxed Intel processors (also known as OEM processors) can be found in the appropriate processor Specification Update, which can be found at Intel? Boxed Processor Test Specification Informationsor. Where applicable, notes have been added to clarify differences between boxed processors. For a complete set of processor features, consult the applicable processor Specification Update.
