420-524: A contract with Intel , becoming a licensed second-source manufacturer of 8086 and 8088 processors. IBM wanted to use the Intel 8088 in its IBM PC , but its policy at the time was to require at least two sources for its chips. AMD later produced the Am286 under the same arrangement. In 1984, Intel internally decided to no longer cooperate with AMD in supplying product information to shore up its advantage in
525-494: A fast, cost-effective processor. Finally, in an agreement effective 1996, AMD received the rights to the microcode in Intel's x386 and x486 processor families, but not the rights to the microcode in the following generations of processors.

7455-558: The microprocessor market, and Spansion went public in an IPO. On July 24, 2006, AMD announced its acquisition of the Canadian 3D graphics card company ATI Technologies . AMD paid $ 4.3 billion and 58 million shares of its capital stock , for approximately $ 5.4 billion. The transaction was completed on October 25, 2006. On August 30, 2010, AMD announced that it would retire the ATI brand name for its graphics chipsets in favor of
7560-573: The motherboard. Sempron was released as a lower-cost Athlon XP, replacing Duron in the socket A PGA era. It has since been migrated upward to all new sockets, up to AM3 . On October 9, 2001, the Athlon XP was released. On February 10, 2003, the Athlon XP with 512 KB L2 Cache was released. The K8 was a major revision of the K7 architecture, with the most notable features being the addition of
7665-410: The network. They may lack significant hard disk storage space , RAM or even processing power , but many organizations are beginning to look at the cost benefits of eliminating "thick client" desktops that are packed with software (and require software licensing fees) and making more strategic investments. Desktop virtualization simplifies software versioning and patch management, where the new image
7770-644: The new Bulldozer products were slower than the K10 models they were built to replace. The Piledriver microarchitecture was the 2012 successor to Bulldozer, increasing clock speeds and performance relative to its predecessor. Piledriver would be released in AMD FX, APU, and Opteron product lines. Piledriver was subsequently followed by the Steamroller microarchitecture in 2013. Used exclusively in AMD's APUs, Steamroller focused on greater parallelism. In 2015,
7875-711: The new venture's success, AMD's CEO Hector Ruiz stepped down in July 2008, while remaining executive chairman, in preparation for becoming chairman of GlobalFoundries in March 2009. President and COO Dirk Meyer became AMD's CEO. Recessionary losses necessitated AMD cutting 1,100 jobs in 2009. In August 2011, AMD announced that former Lenovo executive Rory Read would be joining the company as CEO, replacing Meyer. In November 2011, AMD announced plans to lay off more than 10% (1,400) of its employees from across all divisions worldwide. In October 2012, it announced plans to lay off an additional 15% of its workforce to reduce costs in
7980-461: The other; that is, each party could "earn" the right to manufacture and sell a product developed by the other, if agreed to, by exchanging the manufacturing rights to a product of equivalent technical complexity. The technical information and licenses needed to make and sell a part would be exchanged for a royalty to the developing company. The 1982 agreement also extended the 1976 AMD–Intel cross-licensing agreement through 1995. The agreement included
8085-549: The paravirtual framework. The term "paravirtualization" was first used in the research literature in association with the Denali Virtual Machine Manager. The term is also used to describe the Xen , L4 , TRANGO , VMware , Wind River and XtratuM hypervisors . All these projects use or can use paravirtualization techniques to support high performance virtual machines on x86 hardware by implementing
8190-436: The perceived shift toward RISC with their own AMD Am29000 (29k) processor; the 29k survived as an embedded processor . The company also increased its EPROM memory market share in the late 1980s. Throughout the 1980s, AMD was a second-source supplier of Intel x86 processors. In 1991, it introduced its 386-compatible Am386 , an AMD-designed chip. Creating its own chips, AMD began to compete directly with Intel. AMD had
8295-506: The point of view of programs running in them. A computer program running on an ordinary operating system can see all resources (connected devices, files and folders, network shares , CPU power, quantifiable hardware capabilities) of that computer. However, programs running inside a container can only see the container's contents and devices assigned to the container. This provides many of the benefits that virtual machines have such as standardization and scalability, while using less resources as
8400-518: The predictability, continuity, and quality of service delivered by their converged infrastructure . For example, companies like HP and IBM provide a hybrid VDI model with a range of virtualization software and delivery models to improve upon the limitations of distributed client computing . Selected client environments move workloads from PCs and other devices to data center servers, creating well-managed virtual clients, with applications and client operating environments hosted on servers and storage in
8505-530: The present. Each CP/CMS user was provided a simulated, stand-alone computer. Each such virtual machine had the complete capabilities of the underlying machine, and (for its user) the virtual machine was indistinguishable from a private system. This simulation was comprehensive, and was based on the Principles of Operation manual for the hardware. It thus included such elements as an instruction set, main memory, interrupts, exceptions, and device access. The result
8610-525: The processor to automatically switch from 6 cores to 3 faster cores when more pure speed is needed. The Magny Cours and Lisbon server parts were released in 2010. The Magny Cours part came in 8 to 12 cores and the Lisbon part in 4 and 6 core parts. Magny Cours is focused on performance while the Lisbon part is focused on high performance per watt. Magny Cours is an MCM ( multi-chip module ) with two hexa-core "Istanbul" Opteron parts. This will use
8715-443: The reduction of capital expenditure, which is replaced by a monthly operational cost. Operating-system-level virtualization, also known as containerization , refers to an operating system feature in which the kernel allows the existence of multiple isolated user-space instances. Such instances, called containers, partitions, virtual environments (VEs) or jails ( FreeBSD jail or chroot jail ), may look like real computers from
8820-425: The right to invoke arbitration of disagreements, and after five years the right of either party to end the agreement with one year's notice. The main result of the 1982 agreement was that AMD became a second-source manufacturer of Intel's x86 microprocessors and related chips, and Intel provided AMD with database tapes for its 8086 , 80186 , and 80286 chips. However, in the event of a bankruptcy or takeover of AMD,
8925-596: The rights to their Nx series of x86-compatible processors. AMD gave the NexGen design team their own building, left them alone, and gave them time and money to rework the Nx686. The result was the K6 processor, introduced in 1997. Although it was based on Socket 7 , variants such as K6-III /450 were faster than Intel's Pentium II (sixth-generation processor). The K7 was AMD's seventh-generation x86 processor, making its debut under
9030-556: The significant performance advantages of paravirtualization. For example, the Xen Windows GPLPV project provides a kit of paravirtualization-aware device drivers, that are intended to be installed into a Microsoft Windows virtual guest running on the Xen hypervisor. Such applications tend to be accessible through the paravirtual machine interface environment. This ensures run-mode compatibility across multiple encryption algorithm models, allowing seamless integration within
9135-439: The software on-the-fly to replace instructions that "pierce the virtual machine" with a different, virtual machine safe sequence of instructions. Hardware-assisted virtualization allows guest operating systems to be run in isolation with virtually no modification to the (guest) operating system. Full virtualization requires that every salient feature of the hardware be reflected into one of several virtual machines – including
9240-558: The two companies' vision for Advanced Micro Computers diverged, AMD bought out Siemens' stake in the American division in 1979. AMD closed Advanced Micro Computers in late 1981 after switching focus to manufacturing second-source Intel x86 microprocessors. Total sales in fiscal year 1978 topped $ 100 million, and in 1979, AMD debuted on the New York Stock Exchange . In 1979, production also began on AMD's new semiconductor fabrication plant in Austin, Texas ;
9345-558: The user interacts with the host computer using another desktop computer or a mobile device by means of a network connection, such as a LAN , Wireless LAN or even the Internet . In addition, the host computer in this scenario becomes a server computer capable of hosting multiple virtual machines at the same time for multiple users. As organizations continue to virtualize and converge their data center environment, client architectures also continue to evolve in order to take advantage of
9450-477: The virtual domain to the host domain), and/or reduce the overall performance degradation of machine execution inside the virtual guest. Paravirtualization requires the guest operating system to be explicitly ported for the para- API – a conventional OS distribution that is not paravirtualization-aware cannot be run on top of a paravirtualizing VMM. However, even in cases where the operating system cannot be modified, components may be available that enable many of
9555-509: The virtual machine. Different types of hardware virtualization include: Full virtualization employs techniques that pools physical computer resources into one or more instances; each running a virtual environment where any software or operating system capable of execution on the raw hardware can be run in the virtual machine. Two common full virtualization techniques are typically used: (a) binary translation and (b) hardware-assisted full virtualization. Binary translation automatically modifies
9660-509: The world's first 512K EPROM in 1984. That year, AMD was listed in the book The 100 Best Companies to Work for in America , and later made the Fortune 500 list for the first time in 1985. By mid-1985, the microchip market experienced a severe downturn, mainly due to long-term aggressive trade practices ( dumping ) from Japan, but also due to a crowded and non-innovative chip market in
9765-783: The x86 architecture through two methods: full virtualization or paravirtualization . Both create the illusion of physical hardware to achieve the goal of operating system independence from the hardware but present some trade-offs in performance and complexity. Full virtualization was not fully available on the x86 platform prior to 2005. Many platform hypervisors for the x86 platform came very close and claimed full virtualization (such as Adeos , Mac-on-Linux, Parallels Desktop for Mac , Parallels Workstation , VMware Workstation , VMware Server (formerly GSX Server), VirtualBox , Win4BSD, and Win4Lin Pro ). In 2005 and 2006, Intel and AMD (working independently) created new processor extensions to
9870-436: Was a clean-sheet design, not a development of earlier processors. The core was specifically aimed at 10–125 W TDP computing products. AMD claimed dramatic performance-per-watt efficiency improvements in high-performance computing (HPC) applications with Bulldozer cores. While hopes were high that Bulldozer would bring AMD to be performance-competitive with Intel once more, most benchmarks were disappointing. In some cases
9975-425: Was a reference to Intel's hegemony over the market, i.e., an anthropomorphization of them as Superman. The number "5" was a reference to the fifth generation of x86 processors; rival Intel had previously introduced its line of fifth-generation x86 processors as Pentium because the U.S. Trademark and Patent Office had ruled that mere numbers could not be trademarked. In 1996, AMD purchased NexGen , specifically for
10080-511: Was a second source for Intel MOS / LSI circuits by 1973, with products such as Am14/1506 and Am14/1507, dual 100-bit dynamic shift registers. By 1975, AMD was producing 212 products – of which 49 were proprietary, including the Am9102 (a static N-channel 1024-bit RAM) and three low-power Schottky MSI circuits: Am25LS07, Am25LS08, and Am25LS09. Intel had created the first microprocessor , its 4-bit 4004 , in 1971. By 1975, AMD entered
10185-605: Was a single machine that could be multiplexed among many users. Hardware-assisted virtualization first appeared on the IBM System/370 in 1972, for use with VM/370 , the first virtual machine operating system. IBM added virtual memory hardware to the System/370 series in 1972 which is not the same as Intel VT-x Rings providing a higher privilege level for Hypervisor to properly control Virtual Machines requiring full access to Supervisor and Program or User modes. With
10290-433: Was acquiring Xilinx , one of the market leaders in field programmable gate arrays and complex programmable logic devices (FPGAs and CPLDs) in an all-stock transaction. The acquisition was completed in February 2022, with an estimated acquisition price of $ 50 billion. In October 2023, AMD acquired an open-source AI software provider, Nod.ai, to bolster its AI software ecosystem. In January 2024, AMD announced it
10395-486: Was announced to integrate a CPU and GPU together on some of AMD's microprocessors, including a built in PCI Express link to accommodate separate PCI Express peripherals, eliminating the northbridge chip from the motherboard. The initiative intended to move some of the processing originally done on the CPU (e.g. floating-point unit operations) to the GPU, which is better optimized for some calculations. The Fusion
10500-530: Was discontinuing the production of all complex programmable logic devices (CPLDs) acquired through Xilinx. In March 2024, a rally in semiconductor stocks pushed AMD's valuation above $ 300B for the first time. In July 2024 AMD announced that it would acquire the Finnish-based artificial intelligence startup company Silo AI in a $ 665 million all-cash deal in an attempt to better compete with AI chip market leader Nvidia . In February 1982, AMD signed
10605-431: Was formally incorporated by Jerry Sanders , along with seven of his colleagues from Fairchild Semiconductor , on May 1, 1969. 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 the company. He later decided to leave to start his own semiconductor company, following
10710-534: Was incorporated into a product for desktop PCs, branded Athlon 64 . On April 21, 2005, AMD released the first dual-core Opteron , an x86-based server CPU. A month later, it released the Athlon 64 X2 , the first desktop-based dual-core processor family. In May 2007, AMD abandoned the string "64" in its dual-core desktop product branding, becoming Athlon X2, downplaying the significance of 64-bit computing in its processors. Further updates involved improvements to
10815-575: Was later renamed the AMD APU (Accelerated Processing Unit). Llano was AMD's first APU built for laptops. Llano was the second APU released, targeted at the mainstream market. It incorporated a CPU and GPU on the same die, as well as northbridge functions, and used " Socket FM1 " with DDR3 memory. The CPU part of the processor was based on the Phenom II "Deneb" processor. AMD suffered an unexpected decrease in revenue based on production problems for
10920-591: Was originally known as AMD Radeon Instinct , but AMD dropped the Radeon brand from the name before AMD Instinct MI100 was introduced in November 2020. In June 2022, supercomputers based on AMD's Epyc CPUs and Instinct GPUs took the lead on the Green500 list of the most power-efficient supercomputers with over 50% lead over any other, and held the top first 4 spots. One of them, the AMD-based Frontier
11025-706: Was succeeded by Lisa Su , a key lieutenant who had been chief operating officer since June. On October 16, 2014, AMD announced a new restructuring plan along with its Q3 results. Effective July 1, 2014, AMD reorganized into two business groups: Computing and Graphics, which primarily includes desktop and notebook processors and chipsets, discrete GPUs, and professional graphics; and Enterprise, Embedded, and Semi-Custom, which primarily includes server and embedded processors, dense servers, semi-custom SoC products (including solutions for gaming consoles ), engineering services, and royalties. As part of this restructuring, AMD announced that 7% of its global workforce would be laid off by
