Intel Pentium D Processor Features
Features Benefits
Dual-Core Provides two execution cores in one physical processor allowing the platform to do more in less time while enjoying smooth interaction with your PC.
Intel® Virtualization Technology Intel® Virtualization Technology enables one hardware platform to function as multiple "virtual" platforms. For businesses, it offers improved manageability, limiting downtime and maintaining worker productivity by isolating computing activities into separate partitions. In the home, it allows creating unique user environments for multiple family members looking to use the same platform simultaneously. (supported only on 900 sequence).
Enhanced Intel SpeedStep® Technology Enables cooler and quieter PC designs—depending on system implementation and usage. (Not available on 820.)
Execute Disable Bit Can help to prevent some classes of viruses and worms that exploit buffer overrun vulnerabilities thus helping to improve the overall security of the system.
Intel® Extended Memory 64 Technology Processors with Intel EM64T allow platforms to access larger amounts of memory and will support 64-bit extended operating systems.

± Intel® Virtualization Technology requires a computer system with an enabled Intel® processor, BIOS, virtual machine monitor (VMM) and for some uses, certain platform software enabled for it. Functionality, performance or other benefits will vary depending on hardware and software configurations. Intel Virtualization Technology-enabled BIOS and VMM applications are currently in development.

‡ Enhanced Intel SpeedStep® Technology for specified units of this processor will be available in the 2nd quarter of 2006. See the Processor Spec Finder at http://processorfinder.intel.com or contact your Intel representative for more information.

† Intel® EM64T requires a computer system with a processor, chipset, BIOS, operating system, device drivers and applications enabled for Intel EM64T. Processor will not operate (including 32-bit operation) without an Intel EM64T-enabled BIOS. Performance will vary depending on your hardware and software configurations. See www.intel.com/technology/64bitextensions/ for more information including details on which processors support Intel EM64T or 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.
