D Processor 800
Sequence Features
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.
