64-bit computing on Intel architecture requires a computer system with a processor, chipset, BIOS, operating system, device 
drivers and applications enabled for Intel
®
 64 architecture. Performance will vary depending on your hardware and software 
configurations. Consult with your system vendor for more information. For more information, visit

.
Intel® AES-NI requires a computer system with an AES-NI enabled processor, as well as non-Intel software to execute the 
instructions in the correct sequence. AES-NI is available on select Intel® processors. For availability, consult your reseller or 
system manufacturer. For more information, see http://software.intel.com/en-us/articles/intel-advanced-encryption-standard-
instructions-aes-ni/ 
Enhanced Intel SpeedStep Technology: See the Processor Spec Finder at http://ark.intel.com or contact your Intel representative 
for more information.
Enabling Execute Disable Bit functionality requires a PC with a processor with Execute Disable Bit capability and a supporting 
operating system. Check with your PC manufacturer to determine whether your system delivers this functionality. For more 
information, visit 
Intel® Virtualization Technology requires a computer system with an enabled Intel® processor, BIOS, virtual machine monitor 
(VMM) and for some uses, certain computer system software enabled for it. Functionality, performance or other benefits will vary 
depending on hardware and software configurations and may require a BIOS update. Software applications may not be compatible 
with all operating systems. Please check with your application vendor. 
Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family, 
not across different processor families. Go to: 
Intel® Turbo Boost Technology requires a PC with a processor with Intel® Turbo Boost Technology capability. Intel Turbo Boost 
Technology performance varies depending on hardware, software and system configuration. Consult your PC manufacturer on 
whether your system delivers Intel Turbo Boost Technology. For more information, visit 
No computer system can provide absolute security under all conditions. Intel® Trusted Execution Technology (Intel® TXT) requires 
a computer system with Intel® Virtualization Technology, an Intel TXT-enabled processor, chipset, BIOS, Authenticated Code 
Modules and an Intel TXT-compatible measured launched environment (MLE). Intel TXT also requires the system to contain a TPM 
v1.s. For more information, visit http://www.intel.com/technology/security
