List of Intel chipsets

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.

Intel i945GC northbridge with Pentium Dual-Core microprocessor

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]

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]
  • 82310 MCA - announced in April 1988.[6] Includes: 82306 Local Channel Support Chip, 82307 DMA Controller/Central Arbiter, 82308 Micro Channel Bus Controller, 82309 Address Bus Controller, 82706 VGA Graphics Controller.[2]
  • 82350 EISA - announced in September 1988.[7][8]
  • 82311 MCA - announced in November 1988.[9][10] 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.[2][8]
  • 82320 MCA - announced in April 1989.[11]
  • 82340SX PC AT - announced in January 1990, it is the Topcat chipset licensed from VLSI.[12]
  • 82340DX PC AT - announced in January 1990, it is the Topcat chipset licensed from VLSI.[12]
  • 82360SL - announced in October 1990.[13] It was a chipset for the mobile 80386SL and 80486SL processors. It integrated DMA controller, an interrupt controller PIC, serial and parallel ports, and power-management logic for the processor.
  • 82350DT EISA - announced in April 1991.[14]

[*] Remapping of PCIE/APIC memory ranges not supported,[36][37] some physical memory might not be accessible (e.g. limited to 3.5 GB or similar).

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.

[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.[50] 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, however all other ones with B2 did.[51] 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.[52]

LGA 1150

Chipsets that support LGA 1150 CPUs are listed below. Haswell and Haswell Refresh CPUs are supported by all listed chipsets; however, a BIOS update is usually required for 8-Series Lynx Point motherboards to support Haswell Refresh CPUs.[55] Broadwell CPUs are supported only by 9-Series chipsets, which are usually referred to as Wildcat Point.[56]

The C1 stepping of the Lynx Point chipset contains a bug  a system could lose connectivity with USB devices plugged into USB 3.0 ports provided by the chipset if the system enters the S3 sleep mode.[57]

LGA 1151 rev 2

While Coffee Lake shares the same socket as Skylake and Kaby Lake, this revision of LGA 1151 is electrically incompatible with 100 and 200 series CPUs.

The 300 Series chipsets were introduced along with Coffee Lake processors, which use the LGA 1151 socket; the enthusiast model was released in the last quarter of 2017,[65] the rest of the line was released in 2018.[66]

Xeon chipsets

C232 and C242 chipsets do not support CPU integrated GPUs, as they lack FDI support. Officially they support only Xeon processors, but some motherboards also support consumer processors (6/7th generation Core for C230 series, 8/9th generation Core for C240 series and its Pentium/Celeron derivatives).

LGA 1200

LGA 1200 is a CPU socket compatible with Comet Lake desktop CPUs. Like its predecessors, LGA 1200 has the same amount of pins its name would suggest: 1200. Under the hood, LGA 1200 is a modified version of LGA 1151, its predecessor and currently the latest CPU socket for Intel CPUs. It features 49 additional protruding pins that are used to improve power delivery and provide support for eventual updates with I/O features.

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).[24] The chipset support for this technology is not very clear for the moment.[25]
  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.
