Engineering sample processors (also known as ES processors) are not intended to be offered for sale or resale to the general public. ES processors are considered "Intel Confidential" processors and are only to be used within Intel or by AUTHORIZED personnel outside of Intel for purposes of testing, evaluating, and/or pre-configuring systems. Every ES processor that is "Loaned" outside of Intel is done so under strict contractual agreements or Non-Disclosure Agreements (NDA) to assure the protection of Intel's intellectual property and the unit during the time it is "Loaned" out.
ES processors are available to those who qualify for, and obtain, an NDA. An IntelÂ® Authorized Distributor can assist with the application to obtain an NDA. There are no other means to obtain sample processors from Intel Customer Support. Engineering sample processors are designed and built like normal processors, but offer additional features for testing purposes. These processors are not packaged or labeled for sale to consumers, and may incur damage when tested by system builders.
