The land grid array (LGA) is a type of surface-mount packaging for integrated circuits (ICs) that is notable for having the pins on the socket — as opposed to pins on the integrated circuit, known as a pin grid array (PGA). An LGA can be electrically connected to a printed circuit board (PCB) either by the use of a socket or by soldering directly to the board.
A multi-chip module (MCM) is generically an electronic assembly where multiple integrated circuits, semiconductor dies and/or other discrete components are integrated, usually onto a unifying substrate, so that in use it can be treated as if it were a larger IC. Other terms for MCM packaging include "heterogeneous integration" or "hybrid integrated circuit". The advantage of using MCM packaging is it allows a manufacturer to use multiple components for modularity and/or to improve yields over a conventional monolithic IC approach.
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.
Socket AM4 is a PGA microprocessor socket used by AMD's central processing units (CPUs) built on the Zen and Excavator 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.
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.
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 for accelerated processing units (APUs).
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.
Socket TR4, also known as Socket SP3r2, is a zero insertion force land grid array (LGA) CPU socket designed by AMD supporting its first- and second-generation Zen-based Ryzen Threadripper desktop processors, launched on August 10, 2017 for the high-end desktop and workstation platforms. It was succeeded by Socket sTRX4 for the third generation of Ryzen Threadripper processors.
LGA 4094 may refer to four physically identical but electrically incompatible CPU sockets for AMD processors:
Zen 4 is the codename for a CPU microarchitecture 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.
Socket sTRX4, also known as Socket SP3r3, is a land grid array (LGA) CPU socket designed by AMD supporting its Zen 2-based Castle Peak Ryzen Threadripper desktop processors, launched on November 25, 2019 for the high-end desktop and workstation platforms
Zen 3 is the codename for a CPU microarchitecture by AMD, released on November 5, 2020. It is the successor to Zen 2 and uses TSMC's 7 nm process for the chiplets and GlobalFoundries's 14 nm process for the I/O die on the server chips and 12 nm for desktop chips. Zen 3 powers Ryzen 5000 mainstream desktop processors and Epyc server processors. Zen 3 is supported on motherboards with 500 series chipsets; 400 series boards also saw support on select B450 / X470 motherboards with certain BIOSes. Zen 3 is the last microarchitecture before AMD switched to DDR5 memory and new sockets, which are AM5 for the desktop "Ryzen" chips alongside SP5 and SP6 for the EPYC server platform. According to AMD, Zen 3 has a 19% higher instructions per cycle (IPC) on average than Zen 2.
AMD Wraith is a family of downdraft type CPU coolers designed by AMD. The Wraith was introduced in 2016 as a top of the line cooler AMD offered which is an upgrade to their previous heatpipe cooler designs and the "near silent" thermal solutions and was included with select FX and A10 APU lineup. The lineup has been expanded to consist four new variants, varying in cooling capabilities and lighting features, and are bundled in many of AMD's Socket AM4 & Socket AM5-based products except some of high-end and high-powered Ryzen CPU line-up. The coolers were supplied by several manufacturers such as Cooler Master, Foxconn, and Delta Electronics.
Socket AM5 is a zero insertion force flip-chip land grid array (LGA) CPU socket designed by Advanced Micro Devices, that is used for AMD Ryzen microprocessors starting with the Zen 4 microarchitecture. AM5 replaces the Socket AM4 and is AMD's first LGA socket designed for mainstream, non-enthusiast CPUs.
