List of Intel chipsets

From Wikipedia, the free encyclopedia
(Redirected from Intel chipset)

Intel i945GC 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

[edit]

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:[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

[edit]

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.[2] This chipset can be used with an 82335 High-integration Interface Device to provide support for the Intel 386SX.[3][4]

[*] Remapping of PCIE/APIC memory ranges not supported,[61][62] 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.

[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] Only later revisions of the 975X chipset boards support Core 2 processors. See MSI 975X Platinum (MS-7246) rev 1.0 (first release), and MSI 975X Platinum Powerup revision (MS-7246) rev 2.1 (released autumn 2006) as example. source: https://web.archive.org/web/20210515170458/http://ixbtlabs.com/articles2/mainboard/msi-975x-platinum-powerup-edition-i975x.html
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.
As for Celeron and Celeron D support, some boards and revisions support it, some not. (see upper example, MSI Powerup Edition has reintroduced back Celeron support, probably due to later released Core2-based Celerons, which were often more powerful than higher clocked Netburst Pentiums 4.

[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

[edit]

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.

LGA 1156

[edit]

Chipsets supporting LGA 1156 CPUs (Lynnfield and Clarkdale).

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.[76] Otherwise these chipsets do not enable unbuffered ECC functionality.

LGA 1155

[edit]

Chipsets supporting LGA 1155 CPUs (Sandy Bridge and Ivy Bridge). The PCIe 2.0 lanes from the PCH ran at 5 GT/s in this series, unlike in the previous LGA 1156 chips.[77]

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.[78] 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.[79]

  • 2 For Ivy Bridge mainstream desktop platform. Ivy Bridge CPUs provide 16 PCIe 3.0 lanes for direct GPU connectivity and additional 4 PCIe 2.0 lanes.[80]

LGA 1150

[edit]

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.[81] Broadwell CPUs are supported only by 9-Series chipsets, which are usually referred to as Wildcat Point.[82]

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.[83]

Intel B360 Cannon Point Chipset Die Shot

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,[93] the rest of the line was released in 2018.[94]

Xeon chipsets

[edit]

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

[edit]

LGA 1200 is a CPU socket designed for Comet Lake and Rocket 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. It features 49 additional protruding pins that are used to improve power delivery and provide support for eventual updates with I/O features.

Notes

[edit]
  1. ^ When applied to computer memory (RAM or cache) the quantities KB, MB and GB are defined as: 1 KB = 1024 B, 1 MB = 1024 KB, 1 GB = 1024 MB, consistent with the JEDEC memory standard.
  2. ^ 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).[40] The chipset support for this technology is not very clear for the moment.[41]
  3. ^ 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.
  4. ^ Remapping of PCIE/APIC memory ranges not supported,[61] some physical memory might not be accessible (e.g. limited to 3.5 GB or similar).
