What is an engineering sample (ES) processor?
Engineering sample (ES) processors are also known as qualification sample processors. They are pre-production processors Intel loans to original equipment manufacturers (OEMs), original device manufacturers (ODMs), and independent software vendors (ISVs) to be used in the product design cycle before product launch.
These processors often include more features than production processors for customer pre-production evaluation and test purposes. ES processors:
- Produced by Intel are the sole property of Intel.
- Produced by Intel are Intel Confidential.
- Are provided by Intel under nondisclosure and/or special loan agreement terms with restrictions on the recipient's handling and use.
- Are not for sale or resale.
- May not have passed commercial regulatory requirements.
- Are not covered under Intel warranty and are generally not supported by Intel.
How do I identify ES processors produced by Intel?
The easiest way to tell if you have an ES processor produced by Intel is to look at the processor topside markings. If you have a four or five-digit Qspec listed like the one pictured below, you have an engineering sample. A production processor has a five digit sSpec on the topside markings. It usually begins with S, like SLB9L.
If you don't find ink or laser markings, the processor may be an unmarked ES processor. Contact Intel if you have an unmarked ES processor.
You can also use the Intel® Processor Identification Utility to help identify if a particular processor is an ES processor produced by Intel.
Once you install and run the Intel Processor Identification Utility on an ES processor, the following message appears in the text box:
The following Intel® Processor appears to be an engineering sample, not a production processor. The utility is designed to support production processors only. Sample processors are not warranted by Intel and are not intended for resale.
Can I get ES processors from Intel?
Due to the pre-production nature of ES processors, they are generally only loaned to OEMs, ODMs, and ISVs for pre-production test and evaluation work under specific contractual terms and conditions to assure the protection of assets and confidential information.
ES processors are not made available to the general public by Intel.
Contact your vendor or place of purchase if you have received an ES processor in place of a production processor.
If you have other questions or concerns, you can contact:
Do you replace engineering samples?No, engineering samples are pre-production units, issued free of charge and are not eligible for warranty.
