specifications, and product descriptions at any time, without notice. The information herein is provided "as-is" and Intel does not
make any representations or warranties whatsoever regarding accuracy of the information, nor on the product features, availability,
functionality, or compatibility of the products listed. Please contact system vendor for more information on specific products or
systems.
Intel classifications are for informational purposes only and consist of Export Control Classification Numbers (ECCN) and Harmonized
Tariff Schedule (HTS) numbers. Any use made of Intel classifications are without recourse to Intel and shall not be construed as a
representation or warranty regarding the proper ECCN or HTS. Your company as an importer and/or exporter is responsible for
determining the correct classification of your transaction.
Refer to Datasheet for formal definitions of product properties and features.
“Announced” SKUs are not yet available. Please refer to the Launch Date for market availability.
‡ This feature may not be available on all computing systems. Please check with the system vendor to determine if your system
delivers this feature, or reference the system specifications (motherboard, processor, chipset, power supply, HDD, graphics controller,
memory, BIOS, drivers, virtual machine monitor-VMM, platform software, and/or operating system) for feature compatibility.
Functionality, performance, and other benefits of this feature may vary depending on system configuration.
The Recommended Customer Price (“RCP”) is pricing guidance for Intel products. Prices are for direct Intel customers, typically
represent 1,000-unit purchase quantities, and are subject to change without notice. Taxes and shipping, etc. not included. Prices may
vary for other package types and shipment quantities, and special promotional arrangements may apply. If sold in bulk, price
represents individual unit. Listing of these RCP does not constitute a formal pricing offer from Intel. Please work with your
appropriate Intel representative to obtain a formal price quotation.
System and Maximum TDP is based on worst case scenarios. Actual TDP may be lower if not all I/Os for chipsets are used.
Low Halogen: Applies only to brominated and chlorinated flame retardants (BFRs/CFRs) and PVC in the final product. Intel
components as well as purchased components on the finished assembly meet JS-709 requirements, and the PCB / substrate meet
IEC 61249-2-21 requirements. The replacement of halogenated flame retardants and/or PVC may not be better for the environment.
WARNING: Altering clock frequency and/or voltage may: (i) reduce system stability and useful life of the system and processor; (ii)
cause the processor and other system components to fail; (iii) cause reductions in system performance; (iv) cause additional heat or
other damage; and (v) affect system data integrity. Intel has not tested, and does not warranty, the operation of the processor beyond
its specifications. Intel assumes no responsibility that the processor, including if used with altered clock frequencies and/or voltages,
will be fit for any particular purpose. For more information, visit
