Advanced Micro Devices, Inc. (AMD) is an American multinational semiconductor company based in Sunnyvale, California, that develops computer processors and related technologies for commercial and consumer markets. Its main products include microprocessors, motherboard chipsets, embedded processors and graphics processors for servers, workstations and personal computers, and processor technologies for handheld devices, digital television, automobiles, game consoles, and other embedded systems applications.
AMD is the second-largest global supplier of microprocessors based on the x86 architecture after Intel Corporation, and the third-largest supplier of graphics processing units. It also owns 21 percent of Spansion, a supplier of non-volatile flash memory. In 2007, AMD ranked eleventh among semiconductor manufacturers in terms of revenue.

AMD chipsets

Before the launch of Athlon 64 processors in 2003, AMD designed chipsets for their processors spanning the K6 and K7 processor generations. The chipsets include the AMD-640, AMD-751 and the AMD-761 chipsets. The situation changed in 2003 with the release of Athlon 64 processors, and AMD chose not to further design its own chipsets for its desktop processors while opening the desktop platform to allow other firms to design chipsets. This is the "Open Platform Initiative". The initiative was proven to be a success, with many firms such as Nvidia, ATI, VIA and SiS developing their own chipset for Athlon 64 processors and later Athlon 64 X2 and Athlon 64 FX processors, including the Quad FX platform chipset from Nvidia.
The initiative went further with the release of Opteron server processors as AMD stopped the design of server chipsets in 2004 after releasing the AMD-8111 chipset, and again opened the server platform for firms to develop chipsets for Opteron processors. As of today, Nvidia and Broadcom are the sole designing firms of server chipsets for Opteron processors.
As the company completed the acquisition of ATI Technologies in 2006, the firm gained the ATI design team for chipsets which previously designed the Radeon Xpress 200 and the Radeon Xpress 3200 chipsets. AMD then renamed the chipsets for AMD processors under AMD branding (for instance, the CrossFire Xpress 3200 chipset was renamed as AMD 580X CrossFire chipset). In February 2007, AMD announced the first AMD-branded chipset since 2004 with the release of the AMD 690G chipset (previously under the development codename RS690), targeted at mainstream IGP computing. It was the industry's first to implement a HDMI 1.2 port on motherboards, shipping for more than a million units. While ATI had aimed at releasing an Intel IGP chipset, the plan was scrapped and the inventories of Radeon Xpress 1250 (codenamed RS600, sold under ATI brand) was sold to two OEMs, Abit and AsRock. Although AMD states the firm will still produce Intel chipsets, Intel had not granted the license of 1333 MHz FSB to ATI. Considering the rivalry between AMD and Intel, AMD is less likely to release more Intel chipset designs in the foreseeable future.
On November 15, 2007, AMD has announced a new chipset series portfolio, the AMD 7-Series chipsets, covering from enthusiast multi-graphics segment to value IGP segment, to replace the AMD 480/570/580 chipsets and AMD 690 series chipsets. Marking AMD's first enthusiast multi-graphics chipset. Discrete graphics chipsets were launched on November 15, 2007 as part of the codenamed Spider desktop platform, and IGP chipsets were launched at a later time in Spring 2008 as part of the codenamed Cartwheel platform.
AMD will also return to the server chipsets market with the next-generation AMD 800S series server chipsets, scheduled to be released in 2009 timeframe.
