Advanced Micro Devices, Inc. (AMD) is an American multinational corporation and semiconductor company based in Santa Clara, California, that develops computer processors and related technologies for business and consumer markets.

ATI Technologies Inc., commonly called ATI, was a Canadian semiconductor technology corporation based in Markham, Ontario, that specialized in the development of graphics processing units and chipsets. Founded in 1985, the company listed publicly in 1993 and was acquired by AMD in 2006. As a major fabrication-less or fabless semiconductor company, ATI conducted research and development in-house and outsourced the manufacturing and assembly of its products. With the decline and eventual bankruptcy of 3dfx in 2000, ATI and its chief rival Nvidia emerged as the two dominant players in the graphics processors industry, eventually forcing other manufacturers into niche roles.

In a computer system, a chipset is a set of electronic components on one or more integrated circuits that manages the data flow between the processor, memory and peripherals. The chipset is usually found on the motherboard of computers. 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 performance.

The southbridge is one of the two chips in the core logic chipset on older personal computer (PC) motherboards, the other being the northbridge. As of 2023, most personal computer devices no longer use a set of two chips, and instead have a single chip acting as the 'chipset', for example Intel's Z790 chipset.

The nForce3 chipset was created by Nvidia as a Media and Communications Processor. Specifically, it was designed for use with the Athlon 64 processor.

The Radeon Xpress 200 is a computer chipset released by ATI. The chipset supports AMD 64-bit processors as well as supporting Intel Pentium 4, Pentium D and Celeron processors. Additionally, it includes support for DDR400 RAM and DDR-2 667 RAM on the Intel Edition.

ATI Avivo is a set of hardware and low level software features present on the ATI Radeon R520 family of GPUs and all later ATI Radeon products. ATI Avivo was designed to offload video decoding, encoding, and post-processing from a computer's CPU to a compatible GPU. ATI Avivo compatible GPUs have lower CPU usage when a player and decoder software that support ATI Avivo is used. ATI Avivo has been long superseded by Unified Video Decoder (UVD) and Video Coding Engine (VCE).

The Xpress 3200 is a revision of the Xpress 200 computer chipset released by ATI. The chipset supports AMD64 processors for Socket 939 and Socket AM2.

AMD 580 chipset series is a computer chipset series designed by the AMD Graphics Product Group, for the AMD processors. It was designed for usage with ATI's CrossFire Multi GPU Technology, with both PCI Express slots running at x16 lanes each.

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 AMD 690 chipset series is an integrated graphics chipset family which was developed and manufactured by AMD subsidiary ATI for both AMD and Intel platforms focusing on both desktop and mobile computing markets. The corresponding chipset for the Intel platform has a marketing name of Radeon Xpress 1200 series.

Unified Video Decoder is the name given to AMD's dedicated video decoding ASIC. There are multiple versions implementing a multitude of video codecs, such as H.264 and VC-1.

The AMD 800 chipset series is a set of chipsets developed by AMD, released in 2009. The chipset series was revealed in its presentation slides during the AMD Financial Analyst Day 2007 held on December 13, 2007. This chipset series also marks the return of AMD to the workstation/server market after the completion of the ATI acquisition in October 2006 with the first server chipsets.

<span class="mw-page-title-main">Platform Controller Hub</span> Family of Intels single-chip chipsets

The Platform Controller Hub (PCH) is a family of Intel's single-chip chipsets, first introduced in 2009. It is the successor to the Intel Hub Architecture, which used two chips–a northbridge and southbridge, and first appeared in the Intel 5 Series.

The AMD 900 chipset series is identical to the AMD 800 chipset series except for the fact that it is only found on Socket AM3+ mainboards, whereas its predecessor is only found on Socket AM3 mainboards. It was released in 2011.

Apollo VP3 is a x86 based Socket 7 chipset which was manufactured by VIA Technologies and was launched in 1997. On its time Apollo VP3 was a high performance, cost effective, and energy efficient chipset. It offered AGP support for Socket 7 processors which was not supported at that moment by Intel, SiS and ALi chipsets. In November 1997 FIC released motherboard PA-2012, which uses Apollo VP3 and has AGP bus. This was the first Socket 7 motherboard supporting AGP.
