with the PCH southbridge where display connectors are attached. It provides a path between an Intel processor and an Intel southbridge on a computer motherboard which carries display data from the graphics controller (North Display) of the Intel processor package to the display connectors attached at some PCH (South Display) versions. It is based on

DisplayPort DisplayPort (DP) is a digital display interface developed by a consortium of PC and chip manufacturers and standardized by the Video Electronics Standards Association (VESA). It is primarily used to connect a video source to a display device su ...

standard. Currently it supports 2 independent 4-bit fixed frequency links/channels/pipes at 2.7Gbit/s data rate. It was first used with the 2010 Core i3, i5 processors and H55, H57, Q57, 3450 southbridges released in 2010. FDI enabled processors require FDI enabled southbridge in order to utilize the graphics controller capability, thus boards based on P55, PM55, and P67 "The P67 chipset .. lacks the flexible display interface" will not be able to take advantage of the graphics controller present on later processors. An FDI capable southbridge and CPU pair is not usable without the existence of the appropriate video connectors on the mainboard. For a list of Intel chipsets which support FDI, see List of Intel chipsets, 5/6/7/8 Series chipsets. For a list of Intel CPUs which support FDI, see

Westmere (microarchitecture) Westmere (formerly Nehalem-C) is the code name given to the 32 nm die shrink of '' Nehalem''. While sharing the same CPU sockets, Westmere included Intel HD Graphics, while Nehalem did not. The first ''Westmere''-based processors were launched ...

Sandy Bridge (microarchitecture) Sandy Bridge is the codename for Intel's 32 nm microarchitecture used in the second generation of the Intel Core processors (Core i7, i5, i3). The Sandy Bridge microarchitecture is the successor to Nehalem and Westmere microarchitecture. ...

Ivy Bridge (microarchitecture) Ivy Bridge is the codename for Intel's 22 nm microarchitecture used in the third generation of the Intel Core processors ( Core i7, i5, i3). Ivy Bridge is a die shrink to 22 nm process based on FinFET ("3D") Tri-Gate transistors, from th ...

Haswell (microarchitecture) Haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy Bridge (which is a die shrink/tick of the Sandy Bridge microarchitecture). Intel officially announced CPUs based ...
