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.

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. 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. Max Turbo Frequency refers to the maximum single-core processor frequency that can be achieved with Intel(R) Turbo Boost Technology. See www.intel.com/technology/turboboost/ for more information. System and Maximum TDP is based on worst case scenarios. Actual TDP may be lower if not all I/Os for chipsets are used. "Announced" SKUs are not yet available. Please refer to the Launch Date for market availability. 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 Intel(R) HT Technology. Some products can support AES New Instructions with a Processor Configuration update, in particular, i7-2630QM/i7-2635QM, i7-2670QM/i72675QM, i5-2430M/i5-2435M, i5-2410M/i5-2415M. Please contact OEM for the BIOS that includes the latest Processor configuration update. Processors that support 64-bit computing on Intel(R) architecture require an Intel 64 architecture-enabled BIOS. Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, not across different processor families.
