AMD FX
AMD FX are a series of high-end AMD microprocessors for personal computers which debuted in 2011, claimed as AMD's first native 8-core desktop processor. The line was introduced with the Bulldozer microarchitecture at launch (codenamed "Zambezi"), and was then succeeded by its derivative Piledriver in 2012 (codenamed "Vishera"). The line aimed at competing with the Intel Core line of desktop processors, in particular processors based on Sandy Bridge and Ivy Bridge architectures. FX has been succeeded by the Ryzen brand of CPUs, based on the Zen architecture, which initially launched in 2017 to compete with Intel's later generation processors such as Skylake. History Prior to FX Launch In the years prior to the AMD FX range of processors, the AMD Phenom II and Athlon II lineup of processors, while not beating Intel's Core lineup in raw performance, were generally competitive when their price was taken into account. By the end of Phenom's lifespan, however, Intel's Sandy Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

XOP Instruction Set
The XOP (''eXtended Operations'') instruction set, announced by AMD on May 1, 2009, is an extension to the 128-bit SSE core instructions in the x86 and AMD64 instruction set for the Bulldozer processor core, which was released on October 12, 2011. However AMD removed support for XOP from Zen (microarchitecture) onward. The XOP instruction set contains several different types of vector instructions since it was originally intended as a major upgrade to SSE. Most of the instructions are integer instructions, but it also contains floating point permutation and floating point fraction extraction instructions. See the index for a list of instruction types. History XOP is a revised subset of what was originally intended as SSE5. It was changed to be similar but not overlapping with AVX, parts that overlapped with AVX were removed or moved to separate standards such as FMA4 (floating-point vector multiply–accumulate) and CVT16 ( Half-precision floating-point conversion imp ...

Ivy Bridge (microarchitecture)
Ivy Bridge is the codename for Intel's 22 nm microarchitecture used in the third generation of the Intel Core processors ( Core i7, i5, i3). Ivy Bridge is a die shrink to 22 nm process based on FinFET ("3D") Tri-Gate transistors, from the former generation's 32 nm Sandy Bridge microarchitecture—also known as tick–tock model. The name is also applied more broadly to the Xeon and Core i7 Extreme Ivy Bridge-E series of processors released in 2013. Ivy Bridge processors are backward compatible with the Sandy Bridge platform, but such systems might require a firmware update (vendor specific). In 2011, Intel released the 7-series Panther Point chipsets with integrated USB 3.0 and SATA 3.0 to complement Ivy Bridge. Volume production of Ivy Bridge chips began in the third quarter of 2011. Quad-core and dual-core-mobile models launched on April 29, 2012 and May 31, 2012 respectively. Core i3 desktop processors, as well as the first 22 ...

Intel Core
Intel Core is a line of multi-core (with the exception of Core Solo and Core 2 Solo) central processing units (CPUs) for midrange, embedded, workstation, high-end and enthusiast computer markets 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. Core was launched in January 2006 as a mobile-only series, consisting of single- and dual-core models. It was then succeeded later in July by the Core 2 series, which included both desktop and mobile processors with up to four cores, and introduced 64-bit support. Since 2008, Intel began introducing the Core i3, Core i5, Core i7 and Core i9 lineup of processors, succeeding Core 2.

Personal Computer
A personal computer, commonly referred to as PC or computer, is a computer designed for individual use. It is typically used for tasks such as Word processor, word processing, web browser, internet browsing, email, multimedia playback, and PC game, gaming. Personal computers are intended to be operated directly by an end user, rather than by a computer expert or technician. Unlike large, costly minicomputers and mainframes, time-sharing by many people at the same time is not used with personal computers. The term home computer has also been used, primarily in the late 1970s and 1980s. The advent of personal computers and the concurrent Digital Revolution have significantly affected the lives of people. Institutional or corporate computer owners in the 1960s had to write their own programs to do any useful work with computers. While personal computer users may develop their applications, usually these systems run commercial software, free-of-charge software ("freeware"), which i ...

List Of AMD Microprocessors
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole".Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help us ...

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. This resulted in clock speed gains of 8–10% and a performance increase of around 15% with similar power characteristics. FX-9590 is around 40% faster than Bulldozer-based FX-8150, mostly because of higher clock speed. Products based on Piledriver were first released on 15 May 2012 with the AMD Accelerated Processing Unit (APU), code-named Trinity, series of mobile products. APUs aimed at desktops followed in early October 2012 with Piledriver-based FX-series CPUs released ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulldozer (microarchitecture)
The AMD Bulldozer Family 15h is a microprocessor microarchitecture for the FX and Opteron line of processors, developed by AMD for the desktop and server markets. Bulldozer is the codename for this family of microarchitectures. It was released on October 12, 2011, as the successor to the K10 microarchitecture. Bulldozer is designed from scratch, not a development of earlier processors. The core is specifically aimed at computing products with TDPs of 10 to 125 watts. AMD claims dramatic performance-per-watt efficiency improvements in high-performance computing (HPC) applications with Bulldozer cores. The ''Bulldozer'' cores support most of the instruction sets implemented by Intel processors ( Sandy Bridge) available at its introduction (including SSSE3, SSE4.1, SSE4.2, AES, CLMUL, and AVX) as well as new instruction sets proposed by AMD; ABM, XOP, FMA4 and F16C. Only Bulldozer GEN4 (Excavator) supports AVX2 instruction sets. Overview According to AMD, Bul ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
AMD-V
x86 virtualization is the use of hardware-assisted virtualization capabilities on an x86/x86-64 CPU. In the late 1990s x86 virtualization was achieved by complex software techniques, necessary to compensate for the processor's lack of hardware-assisted virtualization capabilities while attaining reasonable performance. In 2005 and 2006, both Intel ( VT-x) and AMD ( AMD-V) introduced limited hardware virtualization support that allowed simpler virtualization software but offered very few speed benefits. Greater hardware support, which allowed substantial speed improvements, came with later processor models. Software-based virtualization The following discussion focuses only on virtualization of the x86 architecture protected mode. In protected mode the operating system kernel runs at a higher privilege such as ring 0, and applications at a lower privilege such as ring 3. In software-based virtualization, a host OS has direct access to hardware while the guest OSs have limite ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bit Manipulation Instruction Sets
Bit manipulation instructions sets (BMI sets) are extensions to the x86 instruction set architecture for microprocessors from Intel and AMD. The purpose of these instruction sets is to improve the speed of bit manipulation. All the instructions in these sets are non-SIMD and operate only on general-purpose registers. There are two sets published by Intel: BMI (now referred to as BMI1) and BMI2; they were both introduced with the Haswell microarchitecture with BMI1 matching features offered by AMD's ABM instruction set and BMI2 extending them. Another two sets were published by AMD: ABM (''Advanced Bit Manipulation'', which is also a subset of SSE4a implemented by Intel as part of SSE4.2 and BMI1), and TBM (''Trailing Bit Manipulation'', an extension introduced with Piledriver-based processors as an extension to BMI1, but dropped again in Zen-based processors). ABM (Advanced Bit Manipulation) AMD was the first to introduce the instructions that now form Intel's BMI1 as part ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
