AMD Optimizing C C Compiler

Advanced Micro Devices, Inc. (AMD) is an American multinational semiconductor company based in Santa Clara, California, that develops computer processors and related technologies for business and consumer markets. While it initially manufactured its own processors, the company later outsourced its manufacturing, a practice known as going fabless, after GlobalFoundries was spun off in 2009. AMD's main products include microprocessors, motherboard chipsets, embedded processors, graphics processors, and FPGAs for servers, workstations, personal computers, and embedded system applications.

History

First twelve years

Advanced Micro Devices 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 the footsteps of Robert Noyce (developer of the first silicon integrated circuit at Fairchild in 1959) and Gordon Moore, who together founded the semiconductor company Intel in July 1968.

In September 1969, AMD moved from its temporary location in Santa Clara to Sunnyvale, California. To immediately secure a customer base, AMD initially became a second source supplier of microchips designed by Fairchild and National Semiconductor.Pederson, Jay P

In November 1969, the company manufactured its first product: the Am9300, a 4-bit MSI shift register, which began selling in 1970. Also in 1970, AMD produced its first proprietary product, the Am2501 logic counter, which was highly successful.Lojek, Bo

In 1971, AMD entered the RAM chip market, beginning with the Am3101, a 64-bit bipolar RAM. That year AMD also greatly increased the sales volume of its linear integrated circuits, and by year-end the company's total annual sales reached US$4.6 million.

AMD went public in September 1972. The company 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.Rodengen, p. 55.

Intel had created the first microprocessor, its 4-bit 4004, in 1971. By 1975, AMD entered the microprocessor market with the Am9080, a reverse-engineered clone of the Intel 8080,Rodengen, p. 50. and the Am2900 bit-slice microprocessor family. When Intel began installing microcode in its microprocessors in 1976, it entered into a cross-licensing agreement with AMD, which was granted a copyright license to the microcode in its microprocessors and peripherals, effective October 1976.Advanced Micro Devices, Inc. v.

In 1977, AMD entered into a joint venture with Siemens, a German engineering conglomerate wishing to enhance its technology expertise and enter the American market.Malerba, Franco
''The Semiconductor Business: The Economics of Rapid Growth and Decline''

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; the company already had overseas assembly facilities in Penang and Manila, and began construction on a fabrication plant in San Antonio in 1981.Hitt, Michael; Ireland, R. Duane; Hoskisson, Robert

Technology exchange agreement with Intel

Intel had introduced the first x86 microprocessors in 1978. In 1981, IBM created its PC, and wanted Intel's x86 processors, but only under the condition that Intel also provide a second-source manufacturer for its patented x86 microprocessors. Intel and AMD entered into a 10-year technology exchange agreement, first signed in October 1981 and formally executed in February 1982. The terms of the agreement were that each company could acquire the right to become a second-source manufacturer of semiconductor products developed by 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 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, the cross-licensing agreement would be effectively cancelled.

Beginning in 1982, AMD began volume-producing second-source Intel-licensed 8086, 8088, 80186, and 80188 processors, and by 1984, its own Am286 clone of Intel's 80286 processor, for the rapidly growing market of IBM PCs and IBM clones. It also continued its successful concentration on proprietary bipolar chips. In 1983, it introduced INT.STD.1000, the highest manufacturing quality standard in the industry.

The company continued to spend greatly on research and development, and created 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 the United States. AMD rode out the mid-1980s crisis by aggressively innovating and modernizing, devising the Liberty Chip program of designing and manufacturing one new chip or chipset per week for 52 weeks in fiscal year 1986, and by heavily lobbying the U.S. government until sanctions and restrictions were put in place to prevent predatory Japanese pricing. During this time, AMD withdrew from the DRAM market, and made some headway into the CMOS market, which it had lagged in entering, having focused instead on bipolar chips.

AMD had some success in the mid-1980s with the AMD7910 and AMD7911 "World Chip" FSK modem, one of the first multi-standard devices that covered both Bell and CCITT tones at up to 1200 baud half duplex or 300/300 full duplex. Beginning in 1986, AMD embraced 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 own 386-compatible Am386, an AMD-designed chip. Creating its own chips, AMD began to compete directly with Intel.

AMD had a large, successful flash memory business, even during the dotcom bust. In 2003, to divest some manufacturing and aid its overall cash flow, which was under duress from aggressive microprocessor competition from Intel, AMD spun off its flash memory business and manufacturing into Spansion, a joint venture with Fujitsu, which had been co-manufacturing flash memory with AMD since 1993. In December 2005, AMD divested itself of Spansion in order to focus on the microprocessor market, and Spansion went public in an IPO.

Acquisition of ATI, spin-off of GlobalFoundries, and acquisition of Xilinx

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 stock, for a total of 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 the AMD brand name.

In October 2008, AMD announced plans to spin off manufacturing operations in the form of GlobalFoundries Inc., a multibillion-dollar joint venture with Advanced Technology Investment Co., an investment company formed by the government of Abu Dhabi. The partnership and spin-off gave AMD an infusion of cash and allowed it to focus solely on chip design. To assure the Abu Dhabi investors of 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 the face of declining sales revenue.

AMD acquired the low-power server manufacturer SeaMicro in early 2012, with an eye to bringing out an Arm64 server chip.

On October 8, 2014, AMD announced that Rory Read had stepped down after three years as president and chief executive officer. He was succeeded by Lisa Su, a key lieutenant who had been serving as 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 the end of 2014.

After the GlobalFoundries spin-off and subsequent layoffs, AMD was left with significant vacant space at 1 AMD Place, its aging Sunnyvale headquarters office complex. In August 2016, AMD's 47 years in Sunnyvale came to a close when it signed a lease with the Irvine Company for a new 220,000 sq. ft. headquarters building in Santa Clara. AMD's new location at Santa Clara Square faces the headquarters of archrival Intel across the Bayshore Freeway and San Tomas Aquino Creek. Around the same time, AMD also agreed to sell 1 AMD Place to the Irvine Company. In April 2019, the Irvine Company secured approval from the Sunnyvale City Council of its plans to demolish 1 AMD Place and redevelop the entire 32-acre site into townhomes and apartments.

In October 2020, AMD announced that it was acquiring Xilinx in an all-stock transaction. The acquisition was completed in February 2022, with an estimated acquisition price of $50 billion.

IBM PC and the x86 architecture

In February 1982, AMD signed 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 in order to shore up its advantage in the marketplace, and delayed and eventually refused to convey the technical details of the Intel 80386. In 1987, AMD invoked arbitration over the issue, and Intel reacted by canceling the 1982 technological-exchange agreement altogether. After three years of testimony, AMD eventually won in arbitration in 1992, but Intel disputed this decision. Another long legal dispute followed, ending in 1994 when the Supreme Court of California sided with the arbitrator and AMD.

In 1990, Intel countersued AMD, renegotiating AMD's right to use derivatives of Intel's microcode for its cloned processors. In the face of uncertainty during the legal dispute, AMD was forced to develop clean room designed versions of Intel code for its x386 and x486 processors, the former long after Intel had released its own x386 in 1985. In March 1991, AMD released the Am386, its clone of the Intel 386 processor. By October of the same year it had sold one million units.

In 1993, AMD introduced the first of the Am486 family of processors, which proved popular with a large number of original equipment manufacturers, including Compaq, which signed an exclusive agreement using the Am486. The Am5x86, another Am486-based processor, was released in November 1995, and continued AMD's success as 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.

K5, K6, Athlon, Duron, and Sempron

AMD's first in-house x86 processor was the K5, launched in 1996. The "K" in its name was a reference to Kryptonite, the only substance known to harm comic book character Superman. This itself 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 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 K6-3/450 were faster than Intel's Pentium II (sixth-generation processor).

The K7 was AMD's seventh-generation x86 processor, making its debut under the brand name Athlon on June 23, 1999. Unlike previous AMD processors, it could not be used on the same motherboards as Intel's, due to licensing issues surrounding Intel's Slot 1 connector, and instead used a Slot A connector, referenced to the Alpha processor bus. The Duron was a lower-cost and limited version of the Athlon (64KB instead of 256KB L2 cache) in a 462-pin socketed PGA (socket A) or soldered directly onto 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 512KB L2 Cache was released.

Athlon 64, Opteron and Phenom

The K8 was a major revision of the K7 architecture, with the most notable features being the addition of a 64-bit extension to the x86 instruction set (called x86-64, AMD64, or x64), the incorporation of an on-chip memory controller, and the implementation of an extremely high-performance point-to-point interconnect called HyperTransport, as part of the Direct Connect Architecture. The technology was initially launched as the Opteron server-oriented processor on April 22, 2003. Shortly thereafter, it 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 the microarchitecture, and a shift of the target market from mainstream desktop systems to value dual-core desktop systems. In 2008, AMD started to release dual-core Sempron processors exclusively in China, branded as the Sempron 2000 series, with lower HyperTransport speed and smaller L2 cache. AMD completed its dual-core product portfolio for each market segment.

In September 2007, AMD released the first server Opteron K10 processors, followed in November by the Phenom processor for desktop. K10 processors came in dual-core, triple-core, and quad-core versions, with all cores on a single die. AMD released a new platform codenamed " Spider", which utilized the new Phenom processor, as well as an R770 GPU and a 790 GX/FX chipset from the AMD 700 chipset series. However, AMD built the Spider at 65nm, which was uncompetitive with Intel's smaller and more power-efficient 45nm.

In January 2009, AMD released a new processor line dubbed Phenom II, a refresh of the original Phenom built using the 45 nm process. AMD's new platform, codenamed "Dragon", utilized the new Phenom II processor, and an ATI R770 GPU from the R700 GPU family, as well as a 790 GX/FX chipset from the AMD 700 chipset series. The Phenom II came in dual-core, triple-core and quad-core variants, all using the same die, with cores disabled for the triple-core and dual-core versions. The Phenom II resolved issues that the original Phenom had, including a low clock speed, a small L3 cache, and a Cool'n'Quiet bug that decreased performance. The Phenom II cost less but was not performance-competitive with Intel's mid-to-high-range Core 2 Quads. The Phenom II also enhanced its predecessor's memory controller, allowing it to use DDR3 in a new native socket AM3, while maintaining backward compatibility with AM2+, the socket used for the Phenom, and allowing the use of the DDR2 memory that was used with the platform.

In April 2010, AMD released a new Phenom II Hexa-core (6-core) processor codenamed " Thuban". This was a totally new die based on the hexa-core "Istanbul" Opteron processor. It included AMD's "turbo core" technology, which allows 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 a new G34 socket for dual and quad-socket processors and thus will be marketed as Opteron 61xx series processors. Lisbon uses C32 socket certified for dual-socket use or single socket use only and thus will be marketed as Opteron 41xx processors. Both will be built on a 45 nm SOI process.

Fusion becomes the AMD APU

Following AMD's 2006 acquisition of Canadian graphics company ATI Technologies, an initiative codenamed '' Fusion'' 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 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 the Llano. More AMD APUs for laptops running Windows 7 and Windows 8 OS are being used commonly. These include AMD's price-point APUs, the E1 and E2, and their mainstream competitors with Intel's core i-series: The Vision A- series, the A standing for accelerated. These range from the lower-performance A4 chipset to the A6, A8, and A10. These all incorporate Next-generation Radeon graphics cards, with the A4 utilizing the base Radeon HD chip and the rest using a Radeon R4 graphics card, with the exception of the highest-model A10 (A10-7300) which uses an R6 graphics card.

New microarchitectures

= High-power, high-performance Bulldozer cores

=

Bulldozer was AMD's microarchitecture codename for server and desktop AMD FX processors, first released on October 12, 2011. This family 15h microarchitecture is the successor to the family 10h (K10) microarchitecture design. Bulldozer 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 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, the Excavator microarchitecture replaced Piledriver. Expected to be the last microarchitecture of the Bulldozer series, Excavator focused on improved power efficiency.

= Low-power Cat cores

=

The Bobcat microarchitecture was revealed during a speech from AMD executive vice-president Henri Richard in Computex 2007 and was put into production during the first quarter of 2011. Based on the difficulty competing in the x86 market with a single core optimized for the 10–100 W range, AMD had developed a simpler core with a target range of 1–10 watts. In addition, it was believed that the core could migrate into the hand-held space if the power consumption can be reduced to less than 1 W.

Jaguar is a microarchitecture codename for Bobcat's successor, released in 2013, that is used in various APUs from AMD aimed at the low-power/low-cost market. Jaguar and its derivates would go on to be used in the custom APUs of the PlayStation 4, Xbox One, PlayStation 4 Pro, Xbox One S, and Xbox One X. Jaguar would be later followed by the Puma microarchitecture in 2014.

= Arm architecture-based designs

=
In 2012, AMD announced it was working on Arm products, both as a semi-custom product and server product. The initial server product was announced as the Opteron A1100 in 2014, and 8-core Cortex-A57 based ARMv8-A SoC, and was expected to be followed by an APU incorporating a Graphic Core Next GPU. However, the Opteron A1100 was not released until 2016, with the delay attributed to adding software support. The A1100 was also criticized for not having support from major vendors upon its release.

In 2014, AMD also announced the K12 custom core for release in 2016. While being ARMv8-A instruction set architecture compliant, the K12 is expected to be entirely custom designed targeting server, embedded, and semi-custom markets. While ARM architecture development continued, products based on K12 were subsequently delayed with no release planned, in preference to the development of AMD's x86-based Zen microarchitecture.

Zen-based CPUs and APUs

Zen is a new architecture for x86-64 based Ryzen series CPUs and APUs, introduced in 2017 by AMD and built from the ground up by a team led by Jim Keller, beginning with his arrival in 2012, and taping out before his departure in September 2015. One of AMD's primary goals with Zen was an IPC increase of at least 40%, however in February 2017 AMD announced that they had actually achieved a 52% increase. Processors made on the Zen architecture are built on the 14 nm FinFET node and have a renewed focus on single-core performance and HSA compatibility. Previous processors from AMD were either built in the 32 nm process ("Bulldozer" and "Piledriver" CPUs) or the 28 nm process ("Steamroller" and "Excavator" APUs). Because of this, Zen is much more energy efficient. The Zen architecture is the first to encompass CPUs and APUs from AMD built for a single socket (Socket AM4). Also new for this architecture is the implementation of simultaneous multithreading (SMT) technology, something Intel has had for years on some of their processors with their proprietary Hyper-Threading implementation of SMT. This is a departure from the " Clustered MultiThreading" design introduced with the Bulldozer architecture. Zen also has support for DDR4 memory. AMD released the Zen-based high-end Ryzen 7 "Summit Ridge" series CPUs on March 2, 2017, mid-range Ryzen 5 series CPUs on April 11, 2017, and entry level Ryzen 3 series CPUs on July 27, 2017. AMD later released the Epyc line of Zen derived server processors for 1P and 2P systems. In October 2017, AMD released Zen-based APUs as Ryzen Mobile, incorporating Vega graphics cores. In January 2018 AMD has announced their new lineup plans, with Ryzen 2. AMD launched CPUs with the 12nm Zen+ microarchitecture in April 2018, following up with the 7nm Zen 2 microarchitecture in June 2019, including an update to the Epyc line with new processors using the Zen 2 microarchitecture in August 2019, and Zen 3 slated for release in Q3 2020. As of 2019, AMD's Ryzen processors were reported to outsell Intel's consumer desktop processors. At CES 2020 AMD announced their Ryzen Mobile 4000, as the first 7 nm x86 mobile processor, the first 7 nm 8-core (also 16-thread) high-performance mobile processor, and the first 8-core (also 16-thread) processor for ultrathin laptops. This generation is still based on the Zen 2 architecture. In October 2020 AMD announced their Zen 3 CPU. On PassMark's Single thread performance test the Ryzen 5 5600x bested all other CPUs besides the Ryzen 9 5950X.

The Steam Deck, PlayStation 5, Xbox Series X and Series S all use chips based on the Zen 2 microarchitecture, with proprietary tweaks and different configurations in each system's implementation than AMD sells in its own commercially available APUs.

Graphics products and GPUs

ATI prior to AMD acquisition

Radeon within AMD

In 2008, the ATI division of AMD released the TeraScale microarchitecture implementing a unified shader model. This design replaced the previous fixed-function hardware of previous graphics cards with multipurpose, programmable shaders. Initially released as part of the GPU for the Xbox 360, this technology would go on to be used in Radeon branded HD 2000 parts. Three generations of TeraScale would be designed and used in parts from 2008 to 2014.

Combined GPU and CPU divisions

In a 2009 restructuring, AMD merged the CPU and GPU divisions to support the company's APUs, which fused both graphics and general purpose processing. In 2011, AMD released the successor to TeraScale, Graphics Core Next (GCN). This new microarchitecture emphasized GPGPU compute capability in addition to graphics processing, with a particular aim of supporting heterogeneous computing on AMD's APUs. GCN's reduced instruction set ISA allowed for significantly increased compute capability over TeraScale's very long instruction word ISA. Since GCN's introduction with the HD 7970, five generations of the GCN architecture have been produced from 2008 through at least 2017.

Radeon Technologies Group

In September 2015, AMD separated the graphics technology division of the company into an independent internal unit called the Radeon Technologies Group (RTG) headed by Raja Koduri. This gave the graphics division of AMD autonomy in product design and marketing. The RTG then went on to create and release the Polaris and Vega microarchitectures released in 2016 and 2017, respectively. In particular the Vega, or 5th generation GCN, microarchitecture includes a number of major revisions to improve performance and compute capabilities.

In November 2017, Raja Koduri left RTG and CEO and President Lisa Su took his position. In January 2018, it was reported that two industry veterans joined RTG, namely Mike Rayfield as senior vice president and general manager of RTG, and David Wang as senior vice president of engineering for RTG. In January 2020, AMD announced that its second generation RDNA graphics architecture was in development, with the aim of competing with the Nvidia RTX graphics products for performance leadership. In October 2020, AMD announced their new RX 6000 series series GPUs, their first high-end product based on RDNA2 and capable of handling ray-tracing natively, aiming to challenge Nvidia's RTX 3000 GPUs.

Semi-custom and game console products

In 2012, AMD's then CEO Rory Read began a program to offer semi-custom designs. Rather than AMD simply designing and offering a single product, potential customers could work with AMD to design a custom chip based on AMD's intellectual property. Customers pay a non-recurring engineering fee for design and development, and a purchase price for the resulting semi-custom products. In particular, AMD noted their unique position of offering both x86 and graphics intellectual property. These semi-custom designs would have design wins as the APUs in the PlayStation 4 and Xbox One and the subsequent PlayStation 4 Pro, Xbox One S, Xbox One X, Xbox Series and PlayStation 5. Financially, these semi-custom products would represent a majority of the company's revenue in 2016. In November 2017, AMD and Intel announced that Intel would market a product combining in a single package an Intel Core CPU, a semi-custom AMD Radeon GPU, and HBM2 memory.

AMD motherboard 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 was the "Open Platform Management Architecture" with 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 stated the firm would still produce Intel chipsets, Intel had not granted the license of FSB to ATI.

On November 15, 2007, AMD announced a new chipset series portfolio, the AMD 7-Series chipsets, covering from the enthusiast multi-graphics segment to the 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 returned to the server chipsets market with the AMD 800S series server chipsets. It includes support for up to six SATA 6.0 Gbit/s ports, the C6 power state, which is featured in Fusion processors and AHCI 1.2 with SATA FIS–based switching support. This is a chipset family supporting Phenom processors and Quad FX enthusiast platform (890FX), IGP (890GX).

With the advent of AMD's APUs in 2011, traditional northbridge features such as the connection to graphics and the PCI Express controller were incorporated into the APU die. Accordingly, APUs were connected to a single chip chipset, renamed the Fusion Controller Hub (FCH), which primarily provided southbridge functionality.

AMD released new chipsets in 2017 to support the release of their new Ryzen products. As the Zen microarchitecture already includes much of the northbridge connectivity, the AM4-based chipsets primarily varied in the number of additional PCI Express lanes, USB connections, and SATA connections available. These AM4 chipsets were designed in conjunction with ASMedia.

In February 2002, AMD acquired Alchemy Semiconductor for its Alchemy line of MIPS processors for the hand-held and portable media player markets. On June 13, 2006, AMD officially announced that the line was to be transferred to Raza Microelectronics, Inc., a designer of MIPS processors for embedded applications.

In August 2003, AMD also purchased the Geode business which was originally the Cyrix MediaGX from National Semiconductor to augment its existing line of embedded x86 processor products. During the second quarter of 2004, it launched new low-power Geode NX processors based on the K7 Thoroughbred architecture with speeds of fanless processors and , and processor with fan, of TDP 25 W. This technology is used in a variety of embedded systems (Casino slot machines and customer kiosks for instance), several UMPC designs in Asia markets, as well as the OLPC XO-1 computer, an inexpensive laptop computer intended to be distributed to children in developing countries around the world. The Geode LX processor was announced in 2005 and is said will continue to be available through 2015.

AMD has also introduced 64-bit processors into its embedded product line starting with the AMD Opteron processor. Leveraging the high throughput enabled through HyperTransport and the Direct Connect Architecture these server-class processors have been targeted at high-end telecom and storage applications. In 2007, AMD added the AMD Athlon, AMD Turion, and Mobile AMD Sempron processors to its embedded product line. Leveraging the same 64-bit instruction set and Direct Connect Architecture as the AMD Opteron but at lower power levels, these processors were well suited to a variety of traditional embedded applications. Throughout 2007 and into 2008, AMD has continued to add both single-core Mobile AMD Sempron and AMD Athlon processors and dual-core AMD Athlon X2 and AMD Turion processors to its embedded product line and now offers embedded 64-bit solutions starting with 8 W TDP Mobile AMD Sempron and AMD Athlon processors for fan-less designs up to multi-processor systems leveraging multi-core AMD Opteron processors all supporting longer than standard availability.

The ATI acquisition in 2006 included the Imageon and Xilleon product lines. In late 2008, the entire handheld division was sold off to Qualcomm, who have since produced the Adreno series. Also in 2008, the Xilleon division was sold to Broadcom.

In April 2007, AMD announced the release of the M690T integrated graphics chipset for embedded designs. This enabled AMD to offer complete processor and chipset solutions targeted at embedded applications requiring high-performance 3D and video such as emerging digital signage, kiosk, and Point of Sale applications. The M690T was followed by the M690E specifically for embedded applications which removed the TV output, which required Macrovision licensing for OEMs, and enabled native support for dual TMDS outputs, enabling dual independent DVI interfaces.

In January 2011, AMD announced the AMD Embedded G-Series Accelerated Processing Unit. This was the first APU for embedded applications. These were followed by updates in 2013 and 2016.

In May 2012, AMD Announced the AMD Embedded R-Series Accelerated Processing Unit. This family of products incorporates the Bulldozer CPU architecture, and Discrete-class Radeon HD 7000G Series graphics. This was followed by a system on a chip (SoC) version in 2015 which offered a faster CPU and faster graphics, with support for DDR4 SDRAM memory.
