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" 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 may be the exporter of record, and as such, your company is responsible for determining the
correct classification of any item at the time of export.
“Announced” SKUs are not yet available. Please refer to the Launch Date for market availability.
Some products can support AES New Instructions with a Processor Configuration update, in particular, i7-2630QM/i7-2635QM, i7-2670QM/i7-2675QM, i5-2430M/i5-2435M, i5-2410M/i5-2415M. Please
contact OEM for the BIOS that includes the latest Processor configuration update.
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.
See http://www.intel.com/content/www/us/en/architecture-and-technology/hyper-threading/hyper-threading-technology.html?wapkw=hyper+threading for more information including details on which
processors support Inte HT Technology.
Max Turbo Frequency refers to the maximum single-core processor frequency that can be achieved with Intel® Turbo Boost Technology. See www.intel.com/technology/turboboost/ for more
information.
The Recommended Customer Price (“RCP”) is pricing guidance for Intel products. Prices are for direct Intel customers 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. 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.
For benchmarking data see http://www.intel.com/performance.
Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families. See
http://www.intel.com/content/www/us/en/processors/processor-numbers.html for details.
Processors that support 64-bit computing on Intel® architecture require an Intel 64 architecture-enabled BIOS.
