List of Intel chipsets
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.

- E8870
- Supports 400MHz bus on Itanium 2. Memory interface is natively Quad-Channel 800MHz RDRAM, but uses Memory Repeater Hubs to support DDR memory.

- Supports Pentium 4 on a 800MHz bus. Uses DDR memory up to 400MHz, or DDR-II at 533MHz. 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 with two hard drives.
- 915G (Grantsdale-G)
- 915P with an integrated graphics core. The core is compliant with Vertex and Pixel shader versions 2.0, and has similar specifications and functionality to a GeForce FX 5200 or a Radeon 9600.
- Sub-versions
- 910GL - Does not support the PCI-Express x16 port needed for graphics cards and doesn't support 800MHz bus.
- 915P with an integrated graphics core. The core is compliant with Vertex and Pixel shader versions 2.0, and has similar specifications and functionality to a GeForce FX 5200 or a Radeon 9600.
- 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 1066MHz bus and Intel EM64T technology
- Higher end version of 915. Supports another PAT-like mode and ECC memory, and exclusively uses DDR-II RAM.
Note: Officially, no 9xx chipset can have it's FSB adjusted more than 10% outside of "normal" values (i.e. 533MHz and 800MHz). Some manufacturers have manage to circumvent this feature.
