List Of AMD CPU Microarchitectures
The following is a list of AMD CPU microarchitectures. Nomenclature Historically, AMD's CPU families were given a "K-number" (which originally stood for Kryptonite, an allusion to the Superman comic book character's fatal weakness) starting with their first internal x86 CPU design, the K5, to represent generational changes. AMD has not used K-nomenclature codenames in official AMD documents and press releases since the beginning of 2005, when ''K8'' described the Athlon 64 processor family. AMD now refers to the codename K8 processors as the ''Family 0Fh'' processors. 10h and 0Fh refer to the main result of the CPUID x86 processor instruction. In hexadecimal numbering, 0F(h) (where the ''h'' represents hexadecimal numbering) equals the decimal number 15, and 10(h) equals the decimal number 16. (The "K10h" form that sometimes pops up is an improper hybrid of the "K" code and ''Family XXh'' identifier number.) The Family hexadecimal identifier number can be determined for ...

Advanced Micro Devices
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 th ...

Bobcat (microarchitecture)
The AMD Bobcat Family 14h is a microarchitecture created by AMD for its AMD APUs, aimed at a low-power/low-cost market. It was revealed during a speech from AMD executive vice-president Henri Richard in Computex 2007 and was put into production Q1 2011. One of the major supporters was executive vice-president Mario A. Rivas who felt it was difficult to compete in the x86 market with a single core optimized for the 10–100 W range and actively promoted the development of the simpler core with a target range of 1–10 W. 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. ''Bobcat'' cores are used together with GPU cores in accelerated processing units (APUs) under the "''Fusion''" brand. A simplified architecture diagram was released at AMD's Analyst Day in November 2009. This is similar in concept with earlier AMD research in 2003,AMD 2003 Microprocessor Forum SlidesSlide 11an ...

Freeware
Freeware is software, most often proprietary, that is distributed at no monetary cost to the end user. There is no agreed-upon set of rights, license, or EULA that defines ''freeware'' unambiguously; every publisher defines its own rules for the freeware it offers. For instance, modification, redistribution by third parties, and reverse engineering are permitted by some publishers but prohibited by others. Unlike with free and open-source software, which are also often distributed free of charge, the source code for freeware is typically not made available. Freeware may be intended to benefit its producer by, for example, encouraging sales of a more capable version, as in the freemium and shareware business models. History The term ''freeware'' was coined in 1982 by Andrew Fluegelman, who wanted to sell PC-Talk, the communications application he had created, outside of commercial distribution channels. Fluegelman distributed the program via a process now termed '' shareware''. ...

Zen+
Zen+ is the codename for a computer processor microarchitecture by AMD. It is the successor to the first gen Zen microarchitecture, first released in April 2018, powering the second generation of Ryzen processors, known as Ryzen 2000 for mainstream desktop systems, Threadripper 2000 for high-end desktop setups and Ryzen 3000G (instead of 2000G) for accelerated processing units (APUs). Features Zen+ uses GlobalFoundries' 12 nm fabrication process, an optimization of the 14 nm process used for Zen, with only minor design rule changes. This means that the die sizes between Zen and Zen+ are identical as AMD chose to use the new smaller transistors to increase the amount of empty space, or "dark silicon", between the various features on the die. This was done to improve power efficiency & reduce thermal density to allow for higher clock speeds, rather than design an entirely new floorplan for a physically smaller die (which would have been significantly more work and thus ...
