Intel 440 Chipsets – 440LX, 440EX, 440BX, 440ZX, 440GX

The Intel 440 series of chipsets built on the Pentium’s success to advance Intel dominance. 440LX The 440LX (by this time Intel had dropped the term Triton) was the successor to the Pentium Pro 440FX chipset and was developed by Intel to consolidate on the critical success of the Pentium II processor launched a few months earlier. The most important feature of the 440LX is support for the Accelerated Graphics Port (AGP), a new, fast, dedicated bus designed to eliminate bottlenecks between the CPU, graphics controller and system memory, which will aid fast, high-quality 3D graphics. Other improvements with the LX are more like housekeeping, bringing the Pentium II chipset up to the feature set of the 430TX by providing support for SDRAM and Ultra DMA IDE channels. The chipset includes the Advanced Configuration and Power Interface (ACPI), allowing quick power down and up, remote start-up over a LAN for remote network management, plus temperature and fan speed sensors. The chipset also has better integration with the capabilities of the Pentium II, such as support for dynamic execution and processor pipelining. 440EX The 440EX AGPset, based on the core technology of the 440LX AGPset, is designed for use with the Celeron family of processors. It is ACPI-compliant and extends support for a number of advanced features such as AGP, UltraDMA/33, USB and 66MHz SDRAM, to the Basic PC market segment. 440BX The PC’s system bus had been a bottleneck for too long. Manufacturers of alternative motherboard chipsets had made the first move, pushing Socket 7 chipsets beyond Intel’s 66MHz. Intel’s response came in April 1998, with the release of...
