P6 family processors are IA-32 processors based on the P6 family microarchitecture.

This includes the Pentium

Pro, Pentium

II, Pentium

III, and Pentium

III Xeon

processors.

The Pentium

4, Pentium

D, and Pentium

processor Extreme Editions are based

on the Intel NetBurst

microarchitecture. Most early Intel

Xeon

processors are

based on the Intel NetBurst

microarchitecture.

The Intel

Core

Duo, Intel

Core

Solo and dual-core Intel

Xeon

processor LV

are based on an improved Pentium

M processor microarchitecture. The Intel

Xeon

processor 5100 series, Intel

Core

2 Duo, and Intel

Core

2 Extreme

processors are based on Intel

Core

microarchitecture.

P6 family, Pentium

Core

Solo, Intel

Core

Intel

Xeon

processor LV, and early generations of Pentium 4 and Intel Xeon

processors support IA-32 architecture.

The Intel

Xeon

processor 5100 series, Intel

Core

2 Duo, Intel

Core

Extreme processors, newer generations of Pentium 4 and Intel Xeon processor family

support Intel

64 architecture.

IA-32 architecture is the instruction set architecture and programming environment

for Intel's 32-bit microprocessors.

Intel

64 architecture is the instruction set architecture and programming environ-

ment which is the superset of Intel’s 32-bit and 64-bit architectures. It is compatible

with the IA-32 architecture.

1.2 OVERVIEW OF VOLUME 1: BASIC ARCHITECTURE

A description of this manual’s content follows:

Chapter 1 — About This Manual. Gives an overview of all five volumes of the

Intel® 64 and IA-32 Architectures Software Developer’s Manual. It also describes

the notational conventions in these manuals and lists related Intel manuals and

documentation of interest to programmers and hardware designers.

Chapter 2 — Intel

64 and IA-32 Architectures. Introduces the Intel 64 and IA-

32 architectures along with the families of Intel processors that are based on these

architectures. It also gives an overview of the common features found in these

processors and brief history of the Intel 64 and IA-32 architectures.

Chapter 3 — Basic Execution Environment. Introduces the models of memory

organization and describes the register set used by applications.
