Intel 686 Chipsets

The IntelŪ 440LX AGPset introduced Accelerated Graphics Port capability to the Intel architecture PC platform. This popular chipset provides a fundamental building block for balanced platform performance in a wide variety of PentiumŪ II processor-based desktop systems. Introducing Intel's Quad Port Acceleration optimization for the PentiumŪ II processor, its enhanced features include distributed arbitration and support for up to four outstanding transactions from the CPU in the buffer.

Today's IntelŪ 440LX AGPset Highlights
High-volume, high-quality platform.
Accelerated Graphics Port (AGP) improves overall system bandwidth for superior 3D graphics and video performance.
SDRAM support enables faster memory reads and writes and supports faster data streaming between the Pentium II processor and graphics controller.
Dynamic Power Management Architecture (DPMA) enables enhanced power management and fast resume from powered-down states.
Ultra DMA/33 improves access to all IDE devices including hard disk drives and supports smoother audio/video performance.


The IntelŪ 440BX AGPset is the first chipset to optimize IntelŪ PentiumŪ III processor performance for 3D and video applications with 100-MHz system/memory bus. As Intel's second-generation AGPset with IntelŪ Quad Port Acceleration (QPA), the Intel 440BX AGPset improves the speed of the system bus from 66 MHz to 100 MHz, while increasing the width and depth of buffers to the system bus, Accelerated Graphics Port, SDRAM, and the PCI bus. By optimizing the performance of the Pentium III processor with Dual Independent Bus (DIB) architecture, the new Intel 440BX AGPset supports the emerging set of visual computing applications, including 3D and video applications for design, data visualization, web content creation, education, and gaming.

Optimizing IntelŪ PentiumŪ III processor performance
The Intel 440BX AGPset optimizes the performance of the Intel Pentium III processor in desktop systems by implementing Intel Quad Port Acceleration (QPA). This capability improves system performance through four-port concurrent arbitration of the processor bus, graphics bus, PCI bus, and SDRAM. IntelŪ QPA allows the Intel 440BX AGPset and the Pentium III processor to deliver optimal performance in visual computing applications, including 3D graphics.
