The Intel® Pentium® 4 processor family supporting Hyper-Threading Technology1 (HT Technology) delivers
Intel's advanced, powerful processors for desktop PCs and entry-level workstations that are based on the Intel
NetBurst® microarchitecture. The Pentium 4 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.

Introduction
The Intel® Pentium® 4 processor on 90 nm process in the 775-land package is a follow on to the
Pentium 4 processor in the 478-pin package with enhancements to the Intel NetBurst®
microarchitecture. The Pentium 4 processor on 90 nm process in the 775-land package uses FlipChip Land Grid Array (FC-LGA4) package technology, and plugs into a 775-land LGA socket,
referred to as the LGA775 socket. The Pentium 4 processor in the 775-land package, like its
predecessor, the Pentium 4 processor in the 478-pin package, is based on the same Intel 32-bit
microarchitecture and maintains the tradition of compatibility with IA-32 software.
Note:
In this document the Pentium 4 processor on 90 nm process in the 775-land package is also referred
to as the processor.
The Pentium 4 processor on 90 nm process in the 775-land package supports Hyper-Threading
Technology1. Hyper-Threading Technology allows a single, physical processor to function as two
logical processors. While some execution resources (such as caches, execution units, and buses)
are shared, each logical processor has its own architecture state with its own set of general-purpose
registers, control registers to provide increased system responsiveness in multitasking
environments, and headroom for next generation multithreaded applications. Intel recommends
enabling Hyper-Threading Technology with Microsoft Windows* XP Professional or
Windows* XP Home, and disabling Hyper-Threading Technology via the BIOS for all previous
versions of Windows operating systems. For more information on Hyper-Threading Technology,
see http://www.intel.com/info/hyperthreading. Refer to Section 6.1, for Hyper-Threading
Technology configuration details.
In addition to supporting all the existing Streaming SIMD Extensions 2 (SSE2), there are 13 new
instructions that further extend the capabilities of Intel processor technology. These new
instructions are called Streaming SIMD Extensions 3 (SSE3). These new instructions enhance the
performance of optimized applications for the digital home such as video, image processing, and
media compression technology. 3D graphics and other entertainment applications such as gaming
will have the opportunity to take advantage of these new instructions as platforms with the Pentium
4 processor in the 775-land package and SSE3 become available in the market place.
The processor’s Intel NetBurst microarchitecture FSB uses a split-transaction, deferred reply
protocol like the Pentium 4 processor. The Intel NetBurst microarchitecture FSB uses SourceSynchronous Transfer (SST) of address and data to improve performance by transferring data four
times per bus clock (4X data transfer rate, as in AGP 4X). Along with the 4X data bus, the address
bus can deliver addresses two times per bus clock and is referred to as a "double-clocked" or 2X
address bus. Working together, the 4X data bus and 2X address bus provide a data bus bandwidth
of up to 6.4 GB/s.
The Pentium 4 processor on 90 nm process in the LGA775-land package will also include the
Execute Disable Bit capability previously available in Intel® Itanium® processors. This feature
combined with a support operating system allows memory to be marked as executable or nonexecutable. If code attempts to run in non-executable memory the processor raises an error to the
operating system. This feature can prevent some classes of viruses or worms that exploit buffer
overrun vulnerabilities and can thus help improve the overall security of the system. See the Intel®
Architecture Software Developer's Manual for more detailed information.
