Intel® Pentium® D Processor 800∆ Sequence Datasheet
On 90 nm Process in the 775-land LGA Package and supporting Intel® Extended Memory 64 TechnologyΦ
The Intel® Pentium® D processor delivers Intel's advanced, powerful processors for desktop PCs that are based on
the Intel NetBurst® microarchitecture. The Pentium D processor is designed to deliver performance across
applications and usages where end-users can truly appreciate and experience the performance. These applications
include Internet audio and streaming video, image processing, video content creation, speech, 3D, CAD, games,
multimedia, and multitasking user environments.
Intel® Extended Memory 64 Technology (Intel® EM64T)Φ enables the Pentium D processor to execute operating
systems and applications written to take advantage of the Intel EM64T. The Pentium D processor 840 and 830
supporting Enhanced Intel Speedstep® technology allows tradeoffs to be made between performance and power
consumption.
The Pentium D processor also includes the Execute Disable Bit capability. This feature, combined with a supported
operating system, allows memory to be marked as executable or non-executable.

Δ 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.
Φ 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. Intel EM64T-enabled OS, BIOS, device drivers and applications may not be available. See www.intel.com/technology/architecture-silicon/intel64/ 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.
