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). The MLE could consist of a virtual machine monitor,
an OS or an application. In addition, Intel TXT requires the system to contain a TPM v1.2, as defined by the Trusted Computing
Group and specific software for some uses. For more information, see
http://www.intel.com/technology/security/
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
®
Active Management Technology requires the computer system to have an Intel(R) AMT-enabled chipset, network hardware
and software, as well as connection with a power source and a corporate network connection. Setup requires configuration by the
purchaser and may require scripting with the management console or further integration into existing security frameworks to
enable certain functionality. It may also require modifications of implementation of new business processes. With regard to
notebooks, Intel AMT may not be available or certain capabilities may be limited over a host OS-based VPN or when connecting
wirelessly, on battery power, sleeping, hibernating or powered off. For more information, see
http://www.intel.com/technology/
platform-technology/intel-amt/
Hyper-Threading Technology requires a computer system with a processor supporting HT Technology and an HT Technology-
enabled chipset, BIOS and operating system. Performance will vary depending on the specific hardware and software you use. For
more information including details on which processors support HT Technology, see htp://www.intel.com/info/hyperthreading.
“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 overall system configuration. Check with your PC
manufacturer on whether your system delivers Intel Turbo Boost Technology.For more information, see
http://www.intel.com/
technology/turboboost.”

Technology See the Processor Spec Finder or contact your Intel representative for more information.
Intel processor numbers are not a measure of performance. Processor numbers differentiate features within each processor family,
not across different processor families. See
www.intel.com/products/processor_number for details.
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.
