‡ 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® 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.
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.
“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.
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® HT Technology.
Processors that support 64-bit computing on Intel® architecture require an Intel 64 architecture-enabled BIOS.
