List of Intel chipsets

From Wikipedia, the free encyclopedia

You have new messages (last change).

This is a list of computer motherboard chipsets made by Intel. It is divided into three main categories: those which use the PCI bus for interconnection (the 4x0 series), those which connect using specialised "Hub Links" (the 8xx and Exxxx series) and those which connect using PCI Express (the 9xx series). The chipsets are listed in chronological order.

  • E7500 (Plumas)
    • Similar feature set to 860, but uses dual-channel DDR, and has support for PCI-X, but not AGP.
      • Sub-versions:
      • E7501 - Mostly the same as E7500, but with support for 533 MHz bus and USB 2.0.
      • E7505 (Placer) - E7501 with AGP 8x.
  • E7205 (Granite Bay)
    • Workstation chipset, supports AGP 8x and dual-channel DDR. Other features are the same as 845PE.
  • 875P (Canterwood)
    • Similar to E7205, but adds support for 800 MHz bus, DDR at 400 MHz, Communications Streaming Architecture (CSA), Serial ATA (with RAID in certain configurations) and Performance Acceleration Technology (PAT), a mode deigned to cut down memory latency.
  • 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 only supports 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:
      • 865GL - 865G without external AGP slot.
  • E7525 (Tumwater)
    • Dual Xeon, supports an 800 MHz bus, PCI Express and DDR-II. Other features are the same as 875/865.
      • Sub-versions:
      • E7520/E7320 (Lindenhurst) - Same feature-set as E7525, but has the PCI Express links set out in a way better suited to servers than workstations. In spite of the different names, there is no difference between the E7520 and .

[edit] Pentium M Chipsets

  • 855PM (Odem)
    • Similar feature-set to desktop 845E chipset, but optimised for low-power usage, in combination with the Pentium-M. Also has a CSA bus for the wireless chipset component.
  • 855GM (Montara-GM)
    • 855PM with added graphics core (same design as 865G). Also has the capability to use an external AGP card.
      • Sub-versions:
      • 855GME - Supports 333 MHz memory.

[edit] Itanium Chipsets

  • 460GX
    • Chipset for the original Itanium. A 4x0 series chipset in name, but actually uses "expander buses", similar in design to Hub-Link. Supports Quad-Channel 100 MHz SDRAM and PCI-X.
  • E8870
    • Supports 400 MHz bus on Itanium 2. Memory interface is natively Quad-Channel 800 MHz RDRAM, but uses Memory Repeater Hubs to support DDR memory.

[edit] Pentium 4/D/XE Chipsets

  • 915P (Grantsdale)
    • Supports Pentium 4 on an 800 MHz bus. Uses DDR memory up to 400 MHz, or DDR-II 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 DDR-II and only supporting 2GB of memory.
  • 915G (Grantsdale-G)
    • 915P with an integrated graphics core GMA 900. The core is compliant with Vertex and Pixel shader versions 2.0, and has similar functionality to GeForce FX 5200 64bit and Radeon 9100 IGP, though it does not have Transform & Lighting (T&L) features.
      • Sub-versions:
      • 915GL - Same feature reductions as 915PL, but supports 4GB 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 2GB of memory.
  • 945G (Lakeport-G)
    • A version of the 945P that has a GMA 950 integrated graphics core, supports a 1066 MHz bus.
      • Sub-versions:
      • 945GZ - Same feature reductions as 945PL but with an integrated graphics core. No support for external graphics cards.
  • 955X (Glenwood)

[edit] 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 Socket 8 Pentium Pro or Slot 1 Pentium II.
