Piledriver (microarchitecture)
AMD Piledriver Family 15h is a microarchitecture developed by AMD as the second-generation successor to Bulldozer. It targets desktop, mobile and server markets. It is used for the AMD Accelerated Processing Unit (formerly Fusion), AMD FX, and the Opteron line of processors. The changes over Bulldozer are incremental. Piledriver uses the same "module" design. Its main improvements are to branch prediction and FPU/integer scheduling, along with a switch to hard-edge flip-flops to improve power consumption.
Intel Core
Intel Core is a line of streamlined midrange consumer, workstation and enthusiast computer central processing units (CPUs) marketed by Intel Corporation. These processors displaced the existing mid- to high-end Pentium processors at the time of their introduction, moving the Pentium to the entry level. Identical or more capable versions of Core processors are also sold as Xeon processors for the server and workstation markets. The lineup of Core processors includes the Intel Core i3, Intel Core i5, Intel Core i7, and Intel Core i9, along with the X-series of Intel Core CPUs.
Ryzen
Ryzen (ˈraɪzən ) 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. AMD announced a new series of processors on December 13, 2016, named "Ryzen", and delivered them in Q1 2017, the first of several generations.
Register file
A register file is an array of processor registers in a central processing unit (CPU). Register banking is the method of using a single name to access multiple different physical registers depending on the operating mode. Modern integrated circuit-based register files are usually implemented by way of fast static RAMs with multiple ports. Such RAMs are distinguished by having dedicated read and write ports, whereas ordinary multiported SRAMs will usually read and write through the same ports.
Instructions per cycle
In computer architecture, instructions per cycle (IPC), commonly called instructions per clock is one aspect of a processor's performance: the average number of instructions executed for each clock cycle. It is the multiplicative inverse of cycles per instruction. While early generations of CPUs carried out all the steps to execute an instruction sequentially, modern CPUs can do many things in parallel.
Steamroller (microarchitecture)
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. Steamroller still features two-core modules found in Bulldozer and Piledriver designs called clustered multi-thread (CMT), meaning that one module is marketed as a dual-core processor.
Excavator (microarchitecture)
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 Excavator-based APU for mainstream applications is called Carrizo and was released in 2015. The Carrizo APU is designed to be HSA 1.0 compliant. An Excavator-based APU and CPU variant named Toronto for server and enterprise markets was also produced.
Asus
ASUSTeK Computer Inc. (ˈeɪsuːs, eɪˈsuːs, ɑ:ˈ-, əˈ-; ; stylized as ASUSTeK or ASUS) is a Taiwanese multinational computer, phone hardware and electronics manufacturer headquartered in Beitou District, Taipei, Taiwan. Its products include desktop computers, laptops, netbooks, mobile phones, networking equipment, monitors, wi-fi routers, projectors, motherboards, graphics cards, optical storage, multimedia products, peripherals, wearables, servers, workstations and tablet PCs. The company is also an original equipment manufacturer (OEM).
Opteron
Opteron is AMD's x86 former server and workstation processor line, and was the first processor which supported the AMD64 instruction set architecture (known generically as x86-64). It was released on April 22, 2003, with the SledgeHammer core (K8) and was intended to compete in the server and workstation markets, particularly in the same segment as the Intel Xeon processor. Processors based on the AMD K10 microarchitecture (codenamed Barcelona) were announced on September 10, 2007, featuring a new quad-core configuration.
HyperTransport
HyperTransport (HT), formerly known as Lightning Data Transport, is a technology for interconnection of computer processors. It is a bidirectional serial/parallel high-bandwidth, low-latency point-to-point link that was introduced on April 2, 2001. The HyperTransport Consortium is in charge of promoting and developing HyperTransport technology. HyperTransport is best known as the system bus architecture of AMD central processing units (CPUs) from Athlon 64 through AMD FX and the associated motherboard chipsets.
