Intel handles ordering and spec information as following(this is an example);
Intel sells processors through retail stores, such as Best Buy, Fry’s, your neighborhood computer shop, etc. and wholesale channels such as Hewlett-Packard, Dell, Gateway, etc. or resellers. The wholesale channels are often referred to as original equipment manufacturers (OEMs).
Retail processors are sold in clearly marked individual boxes and typically carry a 3-year warranty directly from Intel.
Wholesale processors are not sold in retail boxes and are typically pre-installed by an OEM or reseller. Intel ships the processors to OEMs in trays so we refer to these types of processors as OEM/Tray processors.
Intel does not provide direct warranty support for wholesale processors. If your processor was sold through an OEM or reseller, you must contact your OEM or reseller for warranty support.
