AMD K9
The AMD K9 represents a microarchitecture by AMD designed to replace the K8 processors, featuring dual-core processing. Development K9 appears originally to have been an ambitious 8 issue per clock cycle core redesign of the K7 or the K8 processor core. At one point, K9 was the ''Greyhound'' project at AMD, and was worked on by the K7 design team beginning in early 2001, with tape-out revision A0 scheduled for 2003. The L1 instruction cache was said to hold decoded instructions, essentially the same as Intel's trace cache. The existence of a massively parallel CPU design concept for heavily multi threaded applications has also been revealed, as a planned successor to K8. This was reportedly canceled in the conceptualization phase, after about 6 months' work. At one time K9 was the internal codename for the dual-core AMD64 processors as the brand Athlon 64 X2 The Athlon 64 X2 is the first native dual-core desktop central processing unit (CPU) designed by Advanced Micro ...

K8 (microarchitecture)
The AMD K8 Hammer, also code-named SledgeHammer, is a computer processor microarchitecture designed by AMD as the successor to the AMD K7 Athlon microarchitecture. The K8 was the first implementation of the AMD64 64-bit extension to the x86 instruction set architecture. Features CPU features table Processors Processors based on the K8 core include: * Athlon 64 - first 64-bit consumer desktop * Athlon 64 X2 - first dual-core ('X2') desktop ** Athlon X2 - later model dual-core desktop with '64' omitted * Athlon 64 FX - enthusiast desktop (multipliers unlocked) * Sempron - low-end, low-cost desktop * Opteron - server market * Turion 64 - mobile computing market * Turion 64 X2 - dual-core mobile processor The K8 core is very similar to the K7. The most radical change is the integration of the AMD64 instructions and an on-chip memory controller. The memory controller drastically reduces memory latency and is largely responsible for most of the performance gains from K7 to K8 ...

X86-64
x86-64 (also known as x64, x86_64, AMD64, and Intel 64) is a 64-bit version of the x86 instruction set, first released in 1999. It introduced two new modes of operation, 64-bit mode and compatibility mode, along with a new 4-level paging mode. With 64-bit mode and the new paging mode, it supports vastly larger amounts of virtual memory and physical memory than was possible on its 32-bit predecessors, allowing programs to store larger amounts of data in memory. x86-64 also expands general-purpose registers to 64-bit, and expands the number of them from 8 (some of which had limited or fixed functionality, e.g. for stack management) to 16 (fully general), and provides numerous other enhancements. Floating-point arithmetic is supported via mandatory SSE2-like instructions, and x87/ MMX style registers are generally not used (but still available even in 64-bit mode); instead, a set of 16 vector registers, 128 bits each, is used. (Each register can store one or two double-preci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

The Inquirer
''The Inquirer'' (stylized as TheINQUIRER) was a British technology tabloid website founded by Mike Magee after his departure from ''The Register'' (of which he was one of the founding members) in 2001. In 2006 the site was acquired by Dutch publisher ''Verenigde Nederlandse Uitgeverijen'' (VNU). Mike Magee later left The Inquirer in February 2008 to work on the ''IT Examiner''. Historically, the magazine was entirely Internet-based with its journalists living all over the world and filing copy online, though in recent years it has been edited from Incisive Media's offices in London. Although traditionally a ' red top', under ''Incisive Media'' it has put more weight behind its journalism, reducing the number of jibes at companies, and moved instead towards sponsored online debates in association with high-profile organisations, most recently, Intel. ''The Inquirer'' ceased publishing on 19 December 2019, partly due to declining digital advertising revenues. Scoops Sony lap ...

Athlon 64 X2
The Athlon 64 X2 is the first native dual-core desktop central processing unit (CPU) designed by Advanced Micro Devices (AMD). It was designed from scratch as native dual-core by using an already multi-CPU enabled Athlon 64, joining it with another functional core on one die, and connecting both via a shared dual-channel memory controller/north bridge and additional control logic. The initial versions are based on the E stepping model of the Athlon 64 and, depending on the model, have either 512 or 1024 KB of L2 cache per core. The Athlon 64 X2 can decode instructions for Streaming SIMD Extensions 3 (SSE3), except those few specific to Intel's architecture. The first Athlon 64 X2 CPUs were released in May 2005, in the same month as Intel's first dual-core processor, the Pentium D. In June 2007, AMD released low-voltage variants of their low-end 65 nm Athlon 64 X2, named "Athlon X2". The Athlon X2 processors feature reduced thermal design power (TDP) of 45 Watt (W).

X86 Microarchitectures
x86 (also known as 80x86 or the 8086 family) is a family of complex instruction set computer (CISC) instruction set architectures initially developed by Intel based on the Intel 8086 microprocessor and its 8088 variant. The 8086 was introduced in 1978 as a fully 16-bit extension of Intel's 8-bit 8080 microprocessor, with memory segmentation as a solution for addressing more memory than can be covered by a plain 16-bit address. The term "x86" came into being because the names of several successors to Intel's 8086 processor end in "86", including the 80186, 80286, 80386 and 80486 processors. The term is not synonymous with IBM PC compatibility, as this implies a multitude of other computer hardware. Embedded systems and general-purpose computers used x86 chips before the PC-compatible market started, some of them before the IBM PC (1981) debut. , most desktop and laptop computers sold are based on the x86 architecture family, while mobile categories such as smartphones or ...
