AMD K6

The K6 microprocessor was launched by AMD in 1997. The main advantage of this particular microprocessor is that it was designed to fit into existing desktop designs for Pentium branded CPUs. It was marketed as a product which could perform as well as its Intel Pentium II equivalent but at a significantly lower price. The K6 had a considerable impact on the PC market and presented Intel with serious competition.

Background

The AMD K6 is a superscalar P5 Pentium-class microprocessor, manufactured by AMD, which superseded the K5. The AMD K6 is based on the Nx686 microprocessor that NexGen was designing when it was acquired by AMD. Despite the name implying a design evolving from the K5, it is in fact a totally different design that was created by the NexGen team, including chief processor architect Greg Favor, and adapted after the AMD purchase. The K6 processor included a feedback dynamic instruction reordering mechanism, MMX instructions, and a floating-point unit (FPU). It was also made pin-compatible with Intel's Pentium, enabling it to be used in the widely available "Socket 7"-based motherboards. Like the AMD K5, Nx586, and Nx686 before it, the K6 translated x86 instructions on the fly into dynamic buffered sequences of micro-operations. A later variation of the K6 CPU, K6-2, added floating point-based SIMD instructions, called 3DNow!.

Advanced Micro Devices

Advanced Micro Devices, Inc. (AMD) is an American worldwide semiconductor company based in Sunnyvale, California, United States, that develops computer-processors and related technologies for business and consumer markets. While initially it manufactured its own processors, the company became fabless after GlobalFoundries was spun off in 2009. AMD's main products include microprocessors, motherboard chipsets, embedded processors and graphics processors for servers, workstations and personal computers, and embedded systems applications.

AMD is the second-largest supplier and only significant rival to Intel in the market for x86-based microprocessors. Since acquiring ATI in 2006, AMD and its competitor Nvidia have dominated the discrete graphics processor unit (GPU) market.

Company history

First twelve years

Advanced Micro Devices was formally incorporated on May 1, 1969, by Jerry Sanders, along with seven of his colleagues from Fairchild Semiconductor. Sanders, an electrical engineer who was the director of marketing at Fairchild, had like many Fairchild executives grown frustrated with the increasing lack of support, opportunity, and flexibility within that company, and decided to leave to start his own semiconductor company. The previous year Robert Noyce, who had invented the first practical integrated circuit or microchip in 1959 at Fairchild, had left Fairchild together with Gordon Moore and founded the semiconductor company Intel in July 1968.

Stock exchange

A stock exchange or bourse is an exchange where stock brokers and traders can buy and/or sell stocks (also called shares), bonds, and other securities. Stock exchanges may also provide facilities for issue and redemption of securities and other financial instruments, and capital events including the payment of income and dividends. Securities traded on a stock exchange include stock issued by listed companies, unit trusts, derivatives, pooled investment products and bonds. Stock exchanges often function as "continuous auction" markets, with buyers and sellers consummating transactions at a central location, such as the floor of the exchange.

To be able to trade a security on a certain stock exchange, it must be listed there. Usually, there is a central location at least for record keeping, but trade is increasingly less linked to such a physical place, as modern markets use electronic networks, which gives them advantages of increased speed and reduced cost of transactions. Trade on an exchange is restricted to brokers who are members of the exchange. In recent years, various other trading venues, such as electronic communication networks, alternative trading systems and "dark pools" have taken much of the trading activity away from traditional stock exchanges.
