The
Chipset Guide
Overview
Every computer purchase, every motherboard
upgrade, every CPU buying decisions comes back to the same thing:
the system chipset. If the CPU is the brain of your PC, the chipset
is its heart. It controls the flow of bits that travel between the
CPU, system memory, and the motherboard bus. Efficient data
transfers, fast expansion bus support, and advanced power management
features are just a few of the things the system chipset is
reponsible for.
Slot 1 AGP
Chipsets
Intel's Slot 1 CPUs are currently the fastest
CPUs available for PCs and Slot 1 is a CPU interface patented by
Intel. This is why there is no other CPU manufacturer producing Slot
1 CPUs currently. Slot 1 offers Intel's GTL+ bus protocol, known
from the Pentium Pro CPU, which hosts the so called dual independend
bus (DIB), which means that the Slot 1 CPUs have one bus which they
use to communicate with the memory and system devices like the PCI
and AGP bus and another bus for communication with the second level
cache, which is built into the Pentium II CPU cartridges. GTL+ is
particularly helpful for multi CPU systems and is a protocol that is
patented by Intel as well. This means to other chipset manufacturers
that they have to license the GTL+ protocol from Intel if they want
to design their own Slot 1 chipsets.
Current Slot 1 CPUs are the Pentium II in the two
flavors of 66 and 100 MHz front side bus (FSB) and the Celeron,
which is nothing else than a Pentium II core without the second
level cache and only designed for 66 MHz FSB.

440LX AGP Chipset - 66 MHz Front Side Bus
The Intel® 440LX AGPset introduced Accelerated
Graphics Port capability to the Intel architecture PC platform. This
popular chip set provides a fundamental building block for balanced
platform performance in a wide variety of Pentium® II
processor-based desktop systems.
This chip set is a great solution for designers
who wish to improve performance in volume desktop PCs, especially
with data or memory-intensive applications such as multimedia
graphics and video that require concurrent data transfers within the
system.
The Intel 440LX AGPset also supports a manageable
client or server in networked business computing environments to
reduce the total cost of ownership.
The Intel 440LX AGPset introduced Intel's Quad
Port Acceleration optimization for the Pentium(r) II processor.
Enhanced features include distributed arbitration and support for up
to four outstanding transactions from the CPU in the buffer.

440BX AGP Chipset - 66/100 MHz Front Side Bus -
NOW ONLY THESE ARE IN RUN
Intel's BX chipset is the first PC chipset that
is offering a system or front side bus that runs at 100 MHz and
therefore enables a higher memory bandwidth as the common 66 MHz FSB
used to.
Intel® 440BX AGPset
The Intel® 440BX AGPset is the first chip set to
deliver 100-MHz system level bandwidth to unleash the full
performance of the Intel® Pentium® II processors at 350-MHz
or 400-MHz. In addition, the Mobile Intel® 440BX chip set is the
first chip set to bring Pentium II processor performance to mobile
systems.
The Intel 440BX AGPset improves system
performance by increasing the bandwidth of the system bus from 66MHz
to 100MHz.
Highest System Performance through Technology
Innovation
The chip set features Intel's Quad Port
Acceleration (QPA) to improve bandwidth between the Pentium II
processor, the Accelerated Graphics Port, 100-MHz SDRAM and the PCI
bus. QPA combines enhanced bus arbitration, deeper buffers,
open-page memory architecture and ECC memory control to improve
system performance.
Ultimate Design Flexibility
The Intel 440BX AGPset provides developers with
maximum design flexibility by delivering one chip set for both 66MHz
and 100MHz system designs. Now, one basic motherboard design
supports all Pentium II processor speeds from 233MHz to 400MHz. This
flexibility can save engineering resources while maximizing use of
investments in BIOS, software development and compatibility testing.
Closing the Gap Between the Desktop and Mobile
The Intel 440BX chip set architecture supports
Mobile Intel Pentium II processor performance—bringing
desktop-like performance to mobile PCs. It also enables mobile
systems to benefit from advanced power management and Wired for
Management capabilities, allowing mobile platforms to function much
like desktop systems when connected to a network.
