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

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]

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.

[*] Remapping of PCIE/APIC memory ranges not supported, [43] some physical memory might not be accessible (e.g. limited to 3.5 GB or similar). Operational configuration is 4 ranks - 2× 2 GB dual rank modules or 4× 1 GB single rank modules - depends on number of motherboard DDR2 slots.

Summary:

[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. [57] 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. [58] 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. [59]

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. [62] Broadwell CPUs are supported only by 9-Series chipsets, which are usually referred to as Wildcat Point. [63]

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. [64]

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). [25] The chipset support for this technology is not very clear for the moment. [26]
  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.

Chipset Electronic component that manages data flow into and out of a CPU

In a computer system, a chipset is a set of electronic components in an integrated circuit known as a "Data Flow Management System" that manages the data flow between the processor, memory and peripherals. It is usually found on the motherboard. Chipsets are usually designed to work with a specific family of microprocessors. Because it controls communications between the processor and external devices, the chipset plays a crucial role in determining system performance.

Northbridge (computing) One of the two chips in the core logic chipset architecture on a PC motherboard

A northbridge or host bridge is one of the two chips in the core logic chipset architecture on a PC motherboard, the other being the southbridge. Unlike the southbridge, the northbridge is connected directly to the CPU via the front-side bus (FSB) and is thus responsible for tasks that require the highest performance. The northbridge, also known as Memory Controller Hub, is usually paired with a southbridge. In systems where they are included, these two chips manage communications between the CPU and other parts of the motherboard, and constitute the core logic chipset of the PC motherboard.

LGA 775 Intel desktop CPU socket

LGA 775, also known as Socket T, is an Intel desktop CPU socket. Unlike earlier common CPU sockets, such as its predecessor Socket 478, the LGA 775 has no socket holes; instead, it has 775 protruding pins which touch contact points on the underside of the processor (CPU).

The AMD 700 chipset series is a set of chipsets designed by ATI for AMD Phenom processors to be sold under the AMD brand. Several members were launched in the end of 2007 and the first half of 2008, others launched throughout the rest of 2008.

The P35 Express is a mainstream desktop computer chipset from Intel released in June 2007, although motherboards featuring the chipset were available a month earlier. The P35 Express chipset supports Intel's LGA 775 socket and Core 2 Duo and Quad processors, and is also known to support 45 nm Wolfdale/Yorkfield dual and quad core CPUs. Theoretically, Intel also dropped support for Intel's Pentium 4 and Pentium D processors with this chipset although late Pentium 4 processors, including both the 32-bit-only (5x0) and the 32-bit/64-bit (5x1), and a few others, were fully supported.

I/O Controller Hub (ICH) is a family of Intel southbridge microchips used to manage data communications between a CPU and a motherboard, specifically Intel chipsets based on the Intel Hub Architecture. It is designed to be paired with a second support chip known as a northbridge. As with any other southbridge, the ICH is used to connect and control peripheral devices.

This is a comparison of chipsets designed by Nvidia.

Intel X58 Chip designed by Intel

The Intel X58 is an Intel chip designed to connect Intel processors with Intel QuickPath Interconnect (QPI) interface to peripheral devices. Supported processors implement the Nehalem microarchitecture and therefore have an integrated memory controller (IMC), so the X58 does not have a memory interface. Initially supported processors were the Core i7, but the chip also supported Nehalem and Westmere-based Xeon processors.

Haswell (microarchitecture) Intel processor microarchitecture

Haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy Bridge. Intel officially announced CPUs based on this microarchitecture on June 4, 2013, at Computex Taipei 2013, while a working Haswell chip was demonstrated at the 2011 Intel Developer Forum. With Haswell, which uses a 22 nm process, Intel also introduced low-power processors designed for convertible or "hybrid" ultrabooks, designated by the "U" suffix.

LGA 1156 Intel desktop CPU socket

LGA 1156, also known as Socket H or H1, is an Intel desktop CPU socket. Its incompatible successor is LGA 1155.

Intel 5 Series is a computing architecture introduced in 2008 that improves the efficiency and balances the use of communication channels in the motherboard. The architecture consists primarily of a central processing unit (CPU) and a single chipset. All motherboard communications and activities circle around these two devices.

LGA 2011

LGA 2011, also called Socket R, is a CPU socket by Intel released on November 14, 2011. It launched alongside with LGA 1356 to replace its predecessor, LGA 1366 and LGA 1567. While LGA 1356 was designed for dual-processor or low-end servers, LGA 2011 was designed for high-end desktops and high-performance servers. The socket has 2011 protruding pins that touch contact points on the underside of the processor.

LGA 1155

LGA 1155, also called Socket H2, is a socket used for Intel microprocessors based on Sandy Bridge and Ivy Bridge microarchitectures.

Skylake (microarchitecture) CPU microarchitecture by Intel

Skylake is the codename used by Intel for a processor microarchitecture that was launched in August 2015 succeeding the Broadwell microarchitecture. Skylake is a microarchitecture redesign using the same 14 nm manufacturing process technology as its predecessor, serving as a "tock" in Intel's "tick–tock" manufacturing and design model. According to Intel, the redesign brings greater CPU and GPU performance and reduced power consumption. Skylake CPUs share their microarchitecture with Kaby Lake, Coffee Lake, Cannon Lake, Whiskey Lake, and Comet Lake CPUs.

LGA 1150 Intel motherboard socket for Haswell CPUs

LGA 1150, also known as Socket H3, is a microprocessor socket used by Intel's central processing units (CPUs) built on the Haswell microarchitecture. This socket is also used by the Haswell's successor, Broadwell microarchitecture.

LGA 1151 Intel microprocessor compatible socket

LGA 1151, also known as Socket H4, is an Intel microprocessor compatible socket which comes in two distinct versions: the first revision which supports both Intel's Skylake and Kaby Lake CPUs, and the second revision which supports Coffee Lake CPUs exclusively.

LGA 1200

LGA 1200 is an Intel microprocessor compatible socket for Comet Lake and Rocket Lake desktop CPUs which was released in Q2 2020.

Rocket Lake is Intel's codename for its 11th generation Core microprocessors. Released on March 30, 2021, it is based on the new Cypress Cove microarchitecture, a variant of Sunny Cove backported to Intel's 14 nm process node. Rocket Lake cores contain significantly more transistors than current Skylake-derived Comet Lake cores.
