List of Intel chipsets

Intel ICH7 southbridge on an Intel D945GCPE desktop motherboard

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

Early IBM XT-compatible mainboards did not have a chipset yet, but relied instead on a collection of discrete TTL chips by Intel:^[1]

• 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

Early chipsets

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.^[2]

List of early Intel chipset includes:^[3][4]

• 82091AA EISA/ISA - Advanced Integrated Peripheral (AIP), includes: floppy disk controller, 2× UARTs, parallel port, IDE controller, oscillator, etc.^[5]

Pentium chipsets

While not an actual Intel chipset bug, the Mercury and Neptune chipsets could be found paired with RZ1000 and CMD640 IDE controllers with data corruption bugs. L2 caches are direct-mapped with SRAM tag RAM, write-back for 430FX, HX, VX, and TX.

Summary:

• 845 (Brookdale)
  • two distinct versions 845 MCH for SDR and 845 MCH for DDR^[27][28]
• 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 533 MHz 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 - The same as 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.

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:
    • 945GZ - Same feature reductions as 945PL but with an integrated GMA 950. Supports 533/800 MT/s FSB and DDR-II 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.

  • Update of G31 with a GMA X4500 integrated graphics core and DDR3 800/1066 support.

^[1] The 975X chipset supports only ×16 PCI Express (electrically) in the top slot when the slot below it is unpopulated. Otherwise it and the lower slot (both attached to the Memory Controller Hub) operate at ×8 electrically.

^[2] Officially 975X supports a maximum of 1066 MT/s FSB. Unofficially, third-party motherboards (Asus, Gigabyte) support certain 1333FSB 45 nm Core2 processors, usually with later BIOS updates.

^[3] The 975X chipset technical specification shows only DDR2-533/667 memory support. Actual implementations of 975X do support DDR2 800.

^[4] VT-d is inherently supported on these chipsets, but may not be enabled by individual OEMs. Always read the motherboard manual and check for BIOS updates. X38/X48 VT-d support is limited to certain Intel, Supermicro, DFI (LanParty) and Tyan boards. VT-d is broken or non existent on some boards until the BIOS is updated. Note that VT-d is a chipset Memory Controller Hub technology, not a processor feature, but this is complicated by later processor generations(Core i3/i5/i7)moving the MCH from the motherboard to the processor package, making only certain i series CPUs support VT-d.

5/6/7/8/9 Series chipsets

The Nehalem microarchitecture moves the memory controller into the processor. For high-end Nehalem processors, the X58 IOH acts as a bridge from the QPI to PCI Express peripherals and DMI to the ICH10 southbridge. For mainstream and lower-end Nehalem processors, the integrated memory controller (IMC) is an entire northbridge (some even having GPUs), and the PCH (Platform Controller Hub) acts as a southbridge.

Not listed below is the 3450 chipset (see Xeon chipsets) which is compatible with Nehalem mainstream and high-end processors but does not claim core iX-compatibility. With either a Core i5 or i3 processor, the 3400-series chipsets enable the ECC functionality of unbuffered ECC memory.^[52] Otherwise these chipsets do not enable unbuffered ECC functionality.

The Cougar Point Intel 6 series chipsets with stepping B2 were recalled due to a hardware bug that causes their 3 Gbit/s Serial ATA to degrade over time until they become unusable. Stepping B3 of the Intel 6 series chipsets will have the fix for this. The Z68 chipset which supports CPU overclocking and use of the integrated graphics does not have this hardware bug.^[53] The Z68 also added support for transparently caching hard disk data on to solid-state drives (up to 64 GB), a technology called Smart Response Technology.^[54]

100/200 Series chipsets

LGA 1151

In June 2015, Intel announced the 100 Series chipsets (codenamed Sunrise Point) for Skylake processors using the LGA 1151 socket.^[63][64]

The 200 Series chipsets (codenamed Union Point) will be introduced along with Kaby Lake processors, which will also use the LGA 1151 socket.

Notes

1. The Pentium Pro, Pentium II/III, and the Celerons based on them are essentially the same design with minor internal revisions and varying cache designs. Because of this, the same chipset can be used for Socket 8, Socket 370, Slot 1, or Slot 2 designs with any CPU in the P6 family. In practice however, newer chipset designs are usually made only for the newer processor packages, and older ones may not be updated to accommodate for recent package designs. In addition, certain chipsets may be implemented in motherboards with different processor packages, much like how the 440FX could be used either with a Pentium Pro (Socket 8) or Pentium II (Slot 1). A new feature for the latest Intel chipsets is hardware virtualization support (Intel VT-d).^[23] The chipset support for this technology is not very clear for the moment.^[24]
2. The Intel 82943GML mobile chipset unofficially supports Core Duo, Core 2 Duo, and Pentium Dual Core processors as well as 667 MHz FSB, which is a popular upgrade for many older notebook computers such as certain models of Acer Aspire 3680.
