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).
There are a number of other companies (AMD, Microchip, Altera, etc.) making specialized chipsets as part of other ICs, and they are not often found in PC hardware (laptop, desktop or server). There are also a number of now defunct companies (like 3com, DEC, SGI) that produced network related chipsets for us in general computers.
One of the most famous chipsets produced by SiS was the late 486-age chipset 496/497 which supported PCI bus among older ISA- and VLB-buses.Mainboards using this chipset and equipped with CPUs such as the Intel 80486DX4, AMD 5x86 or Cyrix Cx5x86 processors had performance and compatibility comparable with early Intel Pentium systems in addition to a lower price.
This was followed by chipsets for PC motherboards and other computer graphics chips. C&T was acquired by Intel in 1997, primarily for its graphics chip business. Former members of C&T founded Asiliant Technologies in January 2000 to continue the support of the CHIPS 65545, 65550, 65555, 69000, 69030, and other notebook and LCD oriented graphics ...
Among PC users then, VIA was best known for its motherboard (core-logic) chipsets. However, VIA's products include audio controllers, network/connectivity controllers, low-power CPUs, and even CD/DVD-writer chipsets. PC and peripheral vendors such as ASUS then bought the chipsets for inclusion into their own product brands.
VIA chipsets support CPUs from Intel, AMD (e.g. the Athlon 64) and VIA themselves (e.g. the VIA C3 or C7).They support CPUs as old as the i386 in the early 1990s. In the early 2000s, their chipsets began to offer on-chip graphics support from VIA's joint venture with S3 Graphics beginning in 2001; this support continued into the early 2010s, with the release of the VX11H in August 2012.
The 100 MHz (P120+) 6x86 was available to OEMs for a price of $450 per chip in bulk quantities. [11] In mid February 1996 Cyrix announced the P166+, P150+, and P133+ to be added to the 6x86 model line. [12] IBM, who produced the chips, also announced they will be selling their own versions of the chips. [13]
