64 AND IA-32 ARCHITECTURES
•
The Intel Celeron processor family focused on the value PC market segment. Its introduction offers an
integrated 128 KBytes of Level 2 cache and a plastic pin grid array (P.P.G.A.) form factor to lower system design
cost.
•
The Intel Pentium III processor introduced the Streaming SIMD Extensions (SSE) to the IA-32 architecture.
SSE extensions expand the SIMD execution model introduced with the Intel MMX technology by providing a
new set of 128-bit registers and the ability to perform SIMD operations on packed single-precision floating-
point values. See Section 2.2.7, “SIMD Instructions.”
•
The Pentium III Xeon processor extended the performance levels of the IA-32 processors with the
enhancement of a full-speed, on-die, and Advanced Transfer Cache.

Pentium
®
4 Processor Family (2000-2006)
The Intel Pentium 4 processor family is based on Intel NetBurst microarchitecture; see Section 2.2.2, “Intel
NetBurst
The Intel Pentium 4 processor introduced Streaming SIMD Extensions 2 (SSE2); see Section 2.2.7, “SIMD Instruc-
tions.” The Intel Pentium 4 processor 3.40 GHz, supporting Hyper-Threading Technology introduced Streaming
SIMD Extensions 3 (SSE3); see Section 2.2.7, “SIMD Instructions.”
Intel 64 architecture was introduced in the Intel Pentium 4 Processor Extreme Edition supporting Hyper-Threading
Technology and in the Intel Pentium 4 Processor 6xx and 5xx sequences.
Intel

Virtualization Technology (Intel
®
VT) was introduced in the Intel Pentium 4 processor 672 and 662.
2.1.8 The
Intel
®
Xeon
®
Processor (2001- 2007)
Intel Xeon processors (with exception for dual-core Intel Xeon processor LV, Intel Xeon processor 5100 series) are
based on the Intel NetBurst microarchitecture; see Section 2.2.2, “Intel NetBurst
Microarchitecture.” As a family,
this group of IA-32 processors (more recently Intel 64 processors) is designed for use in multi-processor server
systems and high-performance workstations.
The Intel Xeon processor MP introduced support for Intel
®
Hyper-Threading Technology; see Section 2.2.8, “Intel®
Hyper-Threading Technology.”
The 64-bit Intel Xeon processor 3.60 GHz (with an 800 MHz System Bus) was used to introduce Intel 64 architec-
ture. The Dual-Core Intel Xeon processor includes dual core technology. The Intel Xeon processor 70xx series
includes Intel Virtualization Technology.
The Intel Xeon processor 5100 series introduces power-efficient, high performance Intel Core
microarchitecture.
This processor is based on Intel 64 architecture; it includes Intel Virtualization Technology and dual-core tech-
nology. The Intel Xeon processor 3000 series are also based on Intel Core microarchitecture. The Intel Xeon
processor 5300 series introduces four processor cores in a physical package, they are also based on Intel Core
microarchitecture.

®
M Processor (2003-2006)
The Intel Pentium M processor family is a high performance, low power mobile processor family with microarchi-
tectural enhancements over previous generations of IA-32 Intel mobile processors. This family is designed for
extending battery life and seamless integration with platform innovations that enable new usage models (such as
extended mobility, ultra thin form-factors, and integrated wireless networking).
Its enhanced microarchitecture includes:
•
Support for Intel Architecture with Dynamic Execution
•
A high performance, low-power core manufactured using Intel’s advanced process technology with copper
interconnect
•
On-die, primary 32-KByte instruction cache and 32-KByte write-back data cache
•
On-die, second-level cache (up to 2 MByte) with Advanced Transfer Cache Architecture
