This article provides a list of motherboard chipsets made by Intel, divided into three main categories: those that use the PCI bus for interconnection (the 4xx series), those that connect using specialized "hub links" (the 8xx series), and those that connect using PCI Express (the 9xx series). The chipsets are listed in chronological order.
Early IBM XT-compatible mainboards did not have have chipset yet, but relied instead on a collection of discrete TTL chips by Intel:
To integrate the functions needed on a mainboard into a smaller amount of ICs, Intel licensed the ZyMOS POACH chipset for its Intel 80286 and Intel 80386SX processors (the 82230/82231 High Integration AT-Compatible Chip Set). This chipset can be used with an 82335 High-integration Interface Device to provide support for the Intel 386SX.
The Intel 440FX (codenamed Natoma), is a chipset from Intel, supporting the Pentium Pro and Pentium II processors. It is the first chipset from Intel that supports Pentium II. It is also known as i440FX and was released in May 1996. Official part numbers include the 82441FX and the 82442FX.
440FX does not support UltraDMA, SDRAM, or AGP. Its southbridge counterpart is the PIIX3.
It was replaced by Intel 440LX.
The designers of the QEMU emulator choose to simulate this chipset and its counterpart PIIX3.
