List of Intel chipsets

This is a list of motherboard chipsets made by Intel. It is 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 chipsets

Intel licensed ZyMOS POACH chipset for Intel 80286 and Intel 80386SX processors (the 82230/82231 High Integration AT-Compatible Chip Set).

List of early Intel chipset includes:^[1]

82350 EISA
82350DT EISA
82310 MCA
82340SX PC AT
82340DX PC AT
82320 MCA
82360SL 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.

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^[10]^[11]
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 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 MHz 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 complaint.
- 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 MHz 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 MHz 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 MHz bus, only supports 2 GB of memory.
945G (Lakeport-G)
- A version of the 945P that has a GMA 950 integrated, supports a 1066 MHz bus.
- Sub-versions:
  - 945GZ - Same feature reductions as 945PL but with an integrated . No support for external graphics cards.
955X (Lakeport)
- Update for 925X, with additional features of "Lakeport" (e.g., PAT features and ECC memory), and uses DDR2.

Core 2 chipsets

All Core 2 Duo chipsets support the Pentium Dual-Core and Celeron processors based on the Core architecture. Support for all NetBurst based processors was officially dropped starting with the P35 chipset family.^[13] However, some vendor's boards still support the older processors.^[14]

5/6/7 Series chipsets

Main article: Intel 5 Series

Core i Series chipsets

The Nehalem microarchitecture, which is the basis of the Core i7 brand and projected additional brands, moves the memory controller onto 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 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.^[25] Otherwise these chipsets do not enable unbuffered ECC functionality.

The Intel 6 series chipsets with step B2 have been recalled due to a hardware bug that causes their 3 Gbits/s Serial ATA to degrade over time until they become unusable. Step 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.^[26] The Z68 also added support for transparently caching hard disk data onto solid-state drives (up to 64GB), a technology called Smart Response Technology.^[27]

Notes

Note 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 only made 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).^[42] The chipset support for this technology is not very clear for the moment.^[43]

Note 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.
