AMD Accelerated Processing Unit

The AMD Accelerated Processing Unit (APU), formerly known as Fusion, is marketing term for a series of 64-bit microprocessors from AMD designed to act as a CPU and graphics accelerator (GPU) on a single chip.

AMD announced the first generation APUs, Llano for high-performance and Brazos for low-power devices in January 2011. The second-generation Trinity for high-performance and Brazos-2 for low-power devices were announced in June 2012. The third-generation Kaveri for high performance devices was launched in January 2014, while Kabini and Temash for low-power devices were announced in summer 2013.

The Sony PlayStation 4 and Microsoft Xbox One eighth generation video game consoles both use semi-custom third-generation low-power APUs.

Although it doesn't use the name "APU", Intel Corporation produces CPU-GPU combinations like its Skylake that are architecturally very similar.

History

The AMD Fusion project started in 2006 with the aim of developing a system on a chip that combined a CPU with a GPU on a single die. AMD took a key step toward realising such a vision when it acquired the graphics chipset manufacturer ATI in 2006. The project reportedly required three internal iterations of the Fusion concept to create a product deemed worthy of release. Reasons contributing to the delay of the project include the technical difficulties of combining a CPU and GPU on the same die at a 45 nm process, and conflicting views on what the role of the CPU and GPU should be within the project.

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.

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.
