AMD Accelerated Processing Unit (APU), formerly known as Fusion, is a series of 64-bit microprocessors from Advanced Micro Devices (AMD), combining a general-purpose AMD64 central processing unit (CPU) and 3D integrated graphics processing unit (IGPU) on a single die.
The ARM Cortex-A5 is a 32-bit processor core licensed by ARM Holdings implementing the ARMv7-A architecture announced in 2009.
The AMD Jaguar Family 16h is a low-power microarchitecture designed by AMD. It is used in APUs succeeding the Bobcat Family microarchitecture in 2013 and being succeeded by AMD's Puma architecture in 2014. It is two-way superscalar and capable of out-of-order execution. It is used in AMD's Semi-Custom Business Unit as a design for custom processors and is used by AMD in four product families: Kabini aimed at notebooks and mini PCs, Temash aimed at tablets, Kyoto aimed at micro-servers, and the G-Series aimed at embedded applications. Both the PlayStation 4 and the Xbox One use chips based on the Jaguar microarchitecture, with more powerful GPUs than AMD sells in its own commercially available Jaguar APUs.
AMD Steamroller Family 15h is a microarchitecture developed by AMD for AMD APUs, which succeeded Piledriver in the beginning of 2014 as the third-generation Bulldozer-based microarchitecture. Steamroller APUs continue to use two-core modules as their predecessors, while aiming at achieving greater levels of parallelism.
AMD Excavator Family 15h is a microarchitecture developed by AMD to succeed Steamroller Family 15h for use in AMD APU processors and normal CPUs. On October 12, 2011, AMD revealed Excavator to be the code name for the fourth-generation Bulldozer-derived core.
The ARM Cortex-A57 is a central processing unit implementing the ARMv8-A 64-bit instruction set designed by ARM Holdings. The Cortex-A57 is an out-of-order superscalar pipeline. It is available as SIP core to licensees, and its design makes it suitable for integration with other SIP cores into one die constituting a system on a chip (SoC).

Zen is the codename for a family of computer processor microarchitectures from AMD, first launched in February 2017 with the first generation of its Ryzen CPUs. It is used in Ryzen, Ryzen Threadripper, and Epyc (server).
Zen is the codename for the first iteration in a family of computer processor microarchitectures of the same name from AMD. It was first used with their Ryzen series of CPUs in February 2017. The first Zen-based preview system was demonstrated at E3 2016, and first substantially detailed at an event hosted a block away from the Intel Developer Forum 2016. The first Zen-based CPUs, codenamed "Summit Ridge", reached the market in early March 2017, Zen-derived Epyc server processors launched in June 2017 and Zen-based APUs arrived in November 2017.
James B. Keller is an American microprocessor engineer best known for his work at AMD and Apple. He was the lead architect of the AMD K8 microarchitecture and was involved in designing the Athlon (K7) and Apple A4/A5 processors. He was also the coauthor of the specifications for the x86-64 instruction set and HyperTransport interconnect. From 2012 to 2015, he returned to AMD to work on the AMD K12 and Zen microarchitectures.
Zen 2 is a computer processor microarchitecture by AMD. It is the successor of AMD's Zen and Zen+ microarchitectures, and is fabricated on the 7 nm MOSFET node from TSMC. The microarchitecture powers the third generation of Ryzen processors, known as Ryzen 3000 for the mainstream desktop chips, Ryzen 4000U/H and Ryzen 5000U for mobile applications, as Threadripper 3000 for high-end desktop systems, and as Ryzen 4000G for accelerated processing units (APUs). The Ryzen 3000 series CPUs were released on 7 July 2019, while the Zen 2-based Epyc server CPUs were released on 7 August 2019. An additional chip, the Ryzen 9 3950X, was released in November 2019.
Centriq is a brand of system on a chip (SoC) semiconductor products designed and marketed by Qualcomm for data centers. The Centriq central processing unit (CPU) uses the ARM RISC instruction set, with multiple CPU cores in a single chip.
Ryzen is a brand of multi-core x86-64 microprocessors designed and marketed by AMD for desktop, mobile, server, and embedded platforms based on the Zen microarchitecture. It consists of central processing units (CPUs) marketed for mainstream, enthusiast, server, and workstation segments and accelerated processing units (APUs) marketed for mainstream and entry-level segments and embedded systems applications.
Epyc is a brand of multi-core x86-64 microprocessors designed and sold by AMD, based on the company's Zen microarchitecture. Introduced in June 2017, they are specifically targeted for the server and embedded system markets. Epyc processors share the same microarchitecture as their regular desktop-grade counterparts, but have enterprise-grade features such as higher core counts, more PCI Express lanes, support for larger amounts of RAM, and larger cache memory. They also support multi-chip and dual-socket system configurations by using the Infinity Fabric interconnect.
Zen 4 is the codename for a CPU microarchitecture designed by AMD, released on September 27, 2022. It is the successor to Zen 3 and uses TSMC's N5 process for CCDs. Zen 4 powers Ryzen 7000 mainstream desktop processors and will be used in high-end mobile processors, thin & light mobile processors, as well as Epyc 9004 server processors.
Zen 5 is the codename for an upcoming CPU microarchitecture by AMD, shown on their roadmap in May 2022. It is the successor to Zen 4 and is believed to use TSMC's 3 nm process. It will power Ryzen 8000 mainstream desktop processors, high-end mobile processors, and Epyc 9005 server processors.
