Introduction

Introduction
The Intel Pentium 4 processors 6x1 sequence are the first single-core desktop processors on the
65 nm process. The Pentium 4 processor uses Flip-Chip Land Grid Array (FC-LGA6) package
technology, and plugs into a 775-land surface mount, Land Grid Array (LGA) socket, referred to as
the LGA775 socket.
Note:
In this document, unless otherwise specified, the Intel Pentium 4 processor 6x1 sequence refers
to Intel Pentium 4 processors 661, 651, 641, 631.
Note:
In this document the Intel Pentium 4 processor 6x1 sequence on 65 nm process in the 775-land
package will be referred to as the “Pentium 4 processor,” or simply “the processor.”
The Pentium 4 processor will support Intel Extended Memory 64 Technology (Intel EM64T).
This enhancement allows the processor to execute operating systems and applications written to
take advantage of Intel EM64T. Further details on the 64-bit extension architecture and
programming model are in the Intel Extended Memory 64 Technology Software Developer Guide
at http://developer.intel.com/technology/64bitextensions/.
The Pentium 4 processor 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 and 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 www.intel.com/info/hyperthreading. Refer to
Section 6.1 for Hyper-Threading Technology configuration details.
The Pentium 4 processor’s Intel NetBurst microarchitecture front side bus (FSB) uses a split-
transaction, deferred reply protocol like previous Intel Pentium 4 processors. The Intel NetBurst
microarchitecture FSB uses Source-Synchronous 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 8.5 GB/s.
Intel will enable support components for the Pentium 4 processor including heatsink, heatsink
retention mechanism, and socket. Manufacturability is a high priority; hence, mechanical assembly
may be completed from the top of the baseboard and should not require any special tooling.
The Pentium 4 processor also include the Execute Disable Bit capability previously available in
Intel Itanium processors. This feature, combined with a supported operating system, allows
memory to be marked as executable or non-executable. 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 over run vulnerabilities and can thus help improve
the overall security of the system. See the Intel Architecture Software Developer's Manual for
more detailed information.
