List of Intel chipsets

thumb|300px|Intel i945GC [[Northbridge (computing)|northbridge with Pentium Dual-Core microprocessor]]

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.

Pre-chipset situation

An earlier chipset support for Intel 8085 microprocessor can be found at MCS-85 family section.

Early IBM XT-compatible mainboards did not yet have a chipset, but relied instead on a collection of discrete TTL chips by Intel:

the 8284 clock generator
the 8288 bus controller
the 8254 programmable interval timer
the 8255 parallel I/O interface
the 8259 programmable interrupt controller
the 8237 DMA controller

<!-- Don't know, should we include this? === CT's 82C100 "XT controller" chip ===

One of the first to integrated these functions into a chipset was Chips and Technologies (CT) with its 82C100 "XT controller" chip for Intel 80286.-->

Early chipsets

To integrate the functions needed on a mainboard into a smaller number 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). The 82230 covers this combination of chips: 82C284 clock, 82288 bus controller, and dual 8259A interrupt controllers among with other components. The 82231 covers this combination of chips: 8254 interrupt timer, 74LS612 memory mapper and dual 8237A DMA controller among with other components. Both set were available US$60 for 10 MHz version and US$90 for 12 MHz version in quantities of 100. This chipset can be used with an 82335 High-integration Interface Device to provide support for the Intel 386SX.

82077AA CHMOS Single-Chip Floppy Disk Controller for the 32-bit systems.
82091AA EISA/ISA – Advanced Integrated Peripheral (AIP), includes: floppy disk controller, 2× UARTs, parallel port, IDE controller, oscillator, etc.
82310 MCA family chipset – announced in April 1988. This chipset also supports the 80386SX based machines as well.
82306 Local Channel Support Chip
82307 DMA Controller/Central Arbiter
82308 Micro Channel Bus Controller
82309 Address Bus Controller
82706 VGA Graphics Controller
82311 MCA – announced in November 1988. Includes: 82303 and 82304 Local I/O Channel Support Chips, 82307 DMA Controller/Central Arbiter, 82308 Micro Channel Bus Controller, 82309 Address Bus Controller, 82706 VGA Graphics Controller, 82077 Floppy Disk Controller.
82320 MCA – announced in April 1989. This chipset supports the i486 microprocessor. It was expected to be available in the later half of 1989.
82340DX PC AT – announced in January 1990, it is the Topcat chipset licensed from VLSI.
82350DT EISA – announced in April 1991. This version supports Intel486 DX2 CPU.
82360SL – announced in October 1990. It was a chipset for the mobile 80386SL and 80486SL processors. It integrated DMA controller, an interrupt controller PIC, serial and parallel ports, I/O Control, NMI, Real Time Clock, Timers and power-management logic for the processor. This chipset contains 226,000 transistors using the one-micron CHMOS IV technology. It was available for US$45 in quantities of 1,000.
82380 – High Performance 32-Bit DMA Controller with Integrated System Support Peripherals. This chipset has 20-level programmable interrupt controller a superset of Intel's 82C59 PIC. It also has four (x4) 16-bit programmable internal timers which its superset Intel's 82C54 PIT. It also has built-in DRAM refresh controller as well. It is available for US$149 and US$299 for 16 MHz and 20 MHz respectively in quantities of 100. The Intel M82380 met under MIL-STD-883 Rev. C standard. This military device was tested which includes temperature cycling between -55 and 125 °C, hermeticity and extended burn-in. This military version can have transfer rate of 32 Mbytes per seconds at 16 MHz. This military version were available in 132-lead CPGA and 164-lead CQPK. This military version were available for US$520 100-unit of quantities for the PGA version.
82384 – Clock Generator. The available version for US$15 in quantities of 100.
82385 – High Performance 32-Bit Cache Controller. There is 33 MHz version available for the 386DX processor. Paired with 33 MHz 386 CPU and 64-Kbyte memory subsystem, it performed up to 7.8 MIPS. There is 82385SX version for the 386SX microprocessor.

Summary:

845 (Brookdale)
two distinct versions 845 MCH for SDR and 845 MCH for DDR
875P (Canterwood)
Similar to E7205, but adds support for 800 MHz bus, DDR at 400 MHz, Communication Streaming Architecture (CSA), Serial ATA (with RAID in certain configurations) and Performance Acceleration Technology (PAT), a mode purported to cut down memory latency.
SMP capability exists only on Xeon-based (socket 604) motherboards using the 875P chipset. FSB is rated at on these motherboards.
865PE (Springdale)
875P without PAT, though it was possible to enable PAT in some early revisions. Also lacks ECC Memory support.
Sub-versions:
865P – Similar to 865PE, but supports only 400/533 MHz bus and 333 MHz memory.
848P – Single memory channel version of 865PE.
865G (Springdale-G)
865PE with integrated graphics (Intel Extreme Graphics 2). PAT never supported in any revisions.
Sub-versions:
865GV – 865G without external AGP slot.
E7221 (Copper River)
Designed for Pentium 4-based server.
Supports only one physical processor.
A basic SVGA controller is integrated for analog video.
One PCI-X slot can be bridged to the PCI-e ×8 using the Intel 6702PXH 64-bit PCI Hub.
E7230 (Mukilteo)
Similar to the Intel 3000 MCH, but mainly designed for Pentium D-based server.
Supports only one physical processor.
DDR2-667 4-4-4 is not supported.|| || 82854 (GMCH)

SL5PN (C0) some physical memory might not be accessible (e.g. limited to 3.5 GB or similar).

[1] Some later revisions of motherboards based on 945P,945G and 945PL chipset usually supports some Core 2 processors (with later BIOSes). Core 2 Quad is not supported. Only Core 2 Duo, Pentium Dual-Core, and Core2 based Celerons.

Summary:

915P (Grantsdale)
Supports Pentium 4 on an 800 MT/s bus. Uses DDR memory up to 400 MHz, or DDR2 at 533 MHz. Replaces AGP and CSA with PCI Express, and also supports "Matrix RAID", a RAID mode designed to allow the usage of RAID levels 0 and 1 simultaneously with two hard drives. (Normally RAID1+0 would have required four hard drives)
Sub-versions:
915PL – Cut-down version of 915P with no support for DDR2 and only supporting 2 GB of memory.
915G (Grantsdale-G)
915P with an integrated GMA 900. This core contains Pixel Shader version 2.0 only, it does not contain Vertex Shaders nor does it feature Transform & Lighting (T&L) capabilities and therefore is not Direct X 8.1 or 9.0 compliant.
Sub-versions:
915GL – Same feature reductions as 915PL, but supports 4 GB of memory. No support for external graphics cards.
915GV – Same as 915G, but has no way of adding an external graphics card.
910GL – No support for external graphics cards or 800 MT/s bus.
925X (Alderwood)
Higher end version of 915. Supports another PAT-like mode and ECC memory, and exclusively uses DDR-II RAM.
Sub-versions:
925XE – Supports a 1066 MT/s bus.
945P (Lakeport)
Update on 915P, with support for Serial ATA II, RAID mode 5, an improved memory controller with support for DDR-II at 667 MHz and additional PCI Express lanes. Support for DDR-I is dropped. Formal dual-core support was added to this chipset.
Sub-versions:
945PL – No support for 1066 MT/s bus, only supports 2 GB of memory.
945G (Lakeport-G)
A version of the 945P that has a GMA 950 integrated, supports a 1066 MT/s bus.
Sub-versions:
945GC – Same feature reductions as 945PL but with an integrated GMA 950.
945GZ – Same as 945GC but only supports DDR2 memory at 400/533 MT/s. No support for external graphics cards (some boards, like Asus P5GZ-MX, support through ICH7 on PCIe ×16 @4 lanes mode).
955X (Lakeport)
Update for 925X, with additional features of "Lakeport" (e.g., PAT features and ECC memory), and uses DDR2.
