ICH - 82801AA. The first version of the ICH was released in June 1999 along with the Intel 810 northbridge.While its predecessor, the PIIX, was connected to the northbridge through an internal PCI bus with a bandwidth of 133 MB/s, the ICH used a proprietary interface (called by Intel Hub Interface) that linked it to the northbridge through an 8-bit wide, 266 MB/s bus.
Since coreboot initializes the bare hardware, it must be ported to every chipset and motherboard that it supports. As a result, coreboot is available only for a limited number of hardware platforms and motherboard models. One of the coreboot variants is Libreboot, a software distribution partly free of proprietary blobs, aimed at end users.
Intel Cannon Lake Platform Controller Hub die. The PCH architecture supersedes Intel's previous Hub Architecture, with its design addressing the eventual problematic performance bottleneck between the processor and the motherboard. Under the Hub Architecture, a motherboard would have a two piece chipset consisting of a northbridge chip and a ...
Since Intel is replacing the LPC bus with the eSPI bus, super I/O chips that connect to that bus have appeared on the market. Companies that make super I/O controllers include Nuvoton (spun off from Winbond ), [ 2 ] ITE Inc. [ zh ] , [ 2 ] [ 4 ] Fintek Inc. , [ 7 ] ENE Tech. (for laptop) and Microchip Technology (which bought SMSC™).

In 2022, Intel announced that they are dropping the Pentium and Celeron naming schemes for their desktop and laptop entry level processors. The "Intel Processor" branding will be replacing the old Pentium and Celeron naming schemes starting in 2023. [333] [334]
In older Intel/AMD architectures the southbridge is usually linked to the northbridge, which in turn connected to the CPU. Circa 2004 and onward Intel architectures started to link southbridge directly to the CPU (e.g. via Direct Media Interface). Through the use of controller-integrated channel circuitry, the northbridge (or CPU itself) can ...
Laptop computers generally use highly integrated, miniaturized, and customized motherboards. This is one of the reasons that laptop computers are difficult to upgrade and expensive to repair. Often the failure of one laptop component requires the replacement of the entire motherboard, which is usually more expensive than a desktop motherboard.
