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/products/processor_number for details. Over time processor numbers will increment based on changes in

clock, speed, cache, FSB, or other features, and increments are not intended to represent proportional or quantitative increases in any particular

feature. Current roadmap processor number progression is not necessarily representative of future roadmaps. See www.intel.com/products/

processor_number for details.

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 www.intel.com/

technology/platform-technology/intel-amt/

Intel® Trusted Execution Technology (Intel® TXT) requires a computer system with Intel® Virtualization Technology (Intel® Virtualization Technology

(Intel® VT-x) and Intel® Virtualization Technology for Directed I/O (Intel® VT-d)), a 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.

Warning: Altering clock frequency and/or voltage may (i) reduce system stability and useful life of the system and processor; (ii) cause the processor

and other system components to fail; (iii) cause reductions in system performance; (iv) cause additional heat or other damage; and (v) affect system

data integrity. Intel has not tested, and does not warranty, the operation of the processor beyond its specifications.

* 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

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 http://www.intel.com/info/hyperthreading.

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.

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 on whether your system delivers Execute Disable Bit functionality.

Enhanced Intel SpeedStep

Technology for specified units of this processor available Q2/06. See the Processor Spec Finder at http://

processorfinder.intel.com or contact your Intel representative for more information.
