Processors and Their Characteristics

Three of the latest and fastest processors available are the 1 Intel Core i7-980x. This is the leader in speed. For under $1,000 the “3.33GHz Core i7-980x (with overclocking to 3.6 GHz) is Intel’s flagship.” (Murphy, 2010) It's the first desktop-grade CPU with six physical cores, but hyper threading yields 12 virtualized ones. The six cores share 12MB of integrated L3 cache. The end result is a measurable performance boost for optimized applications--and a score of 147 on our World Bench 6 tests.” (Murphy, 2010) Core i7-870 processor Intel’s 2.93GHz (with automatic overclocking to 3.6GHz) Core i7-870. The differences between this $564 processor and the Core i7-980X, though important, result in only a 14 percent decrease in performance from that of the Core i7-980X. The i7-870 drops its internal L3 cache to 8MB. In addition, it carries a 45-nanometer designation (the size of the space between transistors). The smaller this number, the smaller and more numerous the transistors that can be packed onto a processor. Also, this midrange CPU limits you to four memory slots on your motherboard instead of six. BENCHMARK SCORE: 127

AMD has a brand-new, six,-core, 3.2GHz Phenom II X6 1090T processor. Codenamed
"Thuban," this $299, 45-nanometer CPU can hit speeds of up to 3.6GHz as a result of
Turbo Core, the AMD equivalent of Intel's automatic overclocking technology (which is called Turbo Boost). The X6 1090T's 6MB L3 cache is half that of Intel's six-core chip, and it takes a performance hit of 20 percent compared with Intel's Core i7-980X. The X6 1090T also lacks an answer for hyper threading, a critical technological component of Intel's top-shelf CPU lineups. Performance gaps aside, the X6 1090T is the most compatible, against Intel by a mile. This CPU can be used with existing motherboard with AM3 or AM2+ sockets
(after a BIOS upgrade), The combination of a simple upgrade path and the CPU's low price of $299 makes for a great alternative to upgrading your existing motherboard and memory, if you just want the benefits of a new, up-to-date processor.
> BENCHMARK SCORE: 118 The best Processor for graphics and video would be the Intel Core i7-980X, because of the Benchmark score is the highest, and graphics and video are taken into account. If a 1GHz Processor is replaced by a 2GHz processor it will not necessarily run twice as fast. It depends a lot on the clock speed of your computer.

Power in High Micro Processor

...And finally, while significant power savings are desired, they must come at little or no performance impact. The aim of this paper is to highlight the key issues associated. Power, is associated with the power consumption while running an artificial piece of code specifically written to generate maximum CPU activity. THE CPU POWER PROBLEM Figure 1 shows the power consumption for Intel CPUs. The X axis shows the technology generation and the Y-axis the maximum power consumption. As indicated by the dashed line in the main part of the curve, power consumption has been increasing for each new CPU generation. The points to the side of the main curve indicate newer versions of each processor family. These are implemented in newer semiconductor processes with smaller geometries than the lead processor in that family. The reason is that increased power consumption directly impacts CPU and system cost. This cost has two components. The first is thermal cost, which is associated with keeping the devices below the specified operating temperature limits. Maintaining the integrity of packaging at higher temperatures also requires expensive solutions. The second component of the cost of power consumption is the cost of power delivery, i.e., the on-chip, on-package, and on-board decoupling capacitances and interconnect associated with the power distribution network. Increased power consumption at lower voltages increases the magnitude of the current drawn by the CPU. In addition,......

Computer Processor

...thing you need to know about a processor is the speed in which it processes information and there are several ways to measure the speed and they can be misleading. The speeds differ from inside the processor and outside of the processor. You can measure the processor speed in GHz, the system bus in MHz which is the limiting factor of the speed for your new computer. The ratio between the processor speed and the system bus speed is known as the multiplier. In some older system you may have to configure the multiplier in the CMOS setting but however the newer models will do this automatically for you. CPU manufactures have come up with different ways to making the CPU do more work faster. True multiprocessing requires multiple processors and your system has to be designed to hold more than one CPU on a single motherboard. Another option is the dual core processors, which means incorporating multiple processors with multiple ALUs inside a single CPU. The ALUs process information independently but share a single controller. Cache memory uses SRAM where the rest of the system uses DRAM. SRAM is more expensive than DRAM.SRAM can hold its memory as long as there is power to it. There are three types of cache L1 cache, L2 cache and L3 cache. L1 cache is housed on the processor chip itself. L2 cache is inside the processor housing but is not on the processor chip itself. L3 cache is inside the processor housing but is located further away from the processor chip than L2......

The chip was first announced in 2008 but was delayed. In February 2010 the processor was released to the public. Looking at the growth of transistors and using Dr Gordan Moore’s law, which states that “every 18 to 24 months the growth the processing power will double” has over all remained true with some exceptions. From my sources the transistor count roughly stayed the same from 1974 to 1976 as well as from 1985 to 1988. Looking at the rate of transistor growth, for me, besides some periods of slow development namely from 1993 to 1998, as a whole it seems surprisingly fast as the years have passed. To use some examples in 1997 Intel released the 8088 chip which contained 29000 transistors, 1 year later they released the 80286 chip that has 134000 transistors, that’s quadruple the amount of transistors in 1 year. Another example is from April 2007 to march 2008 the count went from......

...The first company to produce a processor chip with 2 billion transistors on it was? Yeah- you guessed it, Intel. In 2010, Intel released their quad-core Itanium Tukwila. 1- Is the growth reasonable? I believe it is. Why? Computer technology has improved in leaps and bounds over the years and there is no slowing it down. So long as we find new and exciting ways to use its application then it’ll grow more and more! 2- Is the growth surprisingly fast? No. Considering that every two years the transistors double on a chip I’d have to say it’s moving along at a great pace. Refer to Moore’s law : Moore's law" is the observation that, over the history of computing hardware, the number of transistors in a dense integrated circuit doubles approximately every two years. The observation is named after Gordon E. Moore, co-founder of the Intel Corporation, whose 1965 paper described a doubling every year in the number of components per integrated circuit. In 1975, he revised the forecast doubling time to two years. His prediction has proven to be accurate, in part because the law now is used in the semiconductor industry to guide long-term planning and to set targets for research and development. The capabilities of many digital electronic devices are strongly linked to Moore's law: quality-adjusted microprocessor prices, memory capacity, sensors and even the number and size of pixels in digital cameras. All of these are improving at roughly exponential rates as well. This......

Adm Processor

...Fusion Family of Accelerated Processing Units (APUs), introduced to market in January 2011, is a new generation of processors that combines the computing processing unit (CPU) and graphics processing unit (GPU) capabilities in a single chip (die). APU-based platforms can deliver a prodigious amount of computational horsepower, and can present enormous opportunities in developing an application ecosystem beyond today’s mainstream computer systems. While APUs seek to deliver a superior, immersive PC experience, they also can provide tangible environmental benefits. By eliminating a chip to chip link and by introducing new holistic power management techniques, the APUs are designed to be more power efficient than current generation platforms that have both computational and graphical capabilities. This paper compares the environmental impact of one of AMD’s first APU products against an equivalent computer platform powered by the current generation of AMD processors (CPUs and GPUs). By conducting a business to consumer (B2C) lifecycle assessment, this study compares the total lifecycle greenhouse gas (GHG) emissions (also known as a “carbon footprint”) of an APU system (based on the 18W dual-core processor codenamed “Zacate” and the M1 chipset codenamed “Hudson”) with the latest AMD system codenamed “Nile” (which is based on an AMD Athlon™ Neo II Dual Core processor, SB820 Southbridge, RS880M Northbridge with an ATI Mobility Radeon™ HD 5430 discrete graphics card).

My opinion on the growth moving fast or slow I would say it’s moving very fast every two years a new processor is out and technology is evolving with it every day. Reaching 100 billion even a trillion transistors will probably be around 2022 since looking at history every chip doubles every two years. References:

Micro Processors

...MICROPROCESSORS A microprocessor is like the decision maker of computers. Without processors the computer would be useless. It is also known as the Central Processing Unit or CPU. The processor does all the calculations in a computer. If there is an input it calculates and produces and output. “The microprocessor chip is an electronic device that is a computer's central processing unit (CPU) aka the brains of your computer. A microprocessor is a single integrated circuit that is a multipurpose, programmable, clock-driven, register based electronic device that accepts binary data as input, processes it according to instructions stored in its memory, and provides results as output”, (Bellis, Pg. 1). Just like other computer parts Microprocessors are a recent invention. It’s amazing to know how fast our computers are today and how fast they are getting day by day as new technologies are being invented. The future of microprocessors is bright. To know how microprocessors started lets go back to the first microprocessor invented, the 4004 by Intel. 4004 was the first integrated microprocessor. As like all the inventions it has improved by a lot since its invention. “Intel 4004 introduced in 1971. The 4004 was not very powerful -- all it could do was add and subtract, and it could only do that 4 bits at a time. But it was amazing that everything was on one chip. Prior to the 4004, engineers built computers either from collections of chips or from discrete components......

Risc Nad Cisc Processors

...Topic: - Study of various RISC and CISC processors ABSTRACT:- This term paper presents two instructions set architectures, particularly the CISC and the RISC, which have been developed as computer architects aimed for a fast, cost-effective design. Included in this paper are the arguments made for each architecture, and of some performance comparisons on RISC and CISC processors. These data are collected from various papers published concerning the RISC versus CISC discussion. INTRODUCTION: - RISC, or Reduced Instruction Set Computer is a type of microprocessor architecture that utilizes a small, highly-optimized set of instructions, rather than a more specialized set of instructions often found in other types of architectures. Though it may seem less effective for a computational task to be executed with many simple instructions rather than a few complex instructions, the simple instructions take fairly the same amount of time to be performed, making them ideal for pipelining. CISC is an acronym for Complex Instruction Set Computer and are chips that are easy to program and which make efficient use of memory. Since the earliest machines were programmed in assembly language and memory was slow and expensive, the CISC philosophy made sense, and was commonly implemented in such large computers as the PDP-11 and the DEC system 10 and 20 machines HISTORY:- The first RISC projects came from IBM, Stanford, and UC-Berkeley in the......

P1 (086) Processor - Intel introduced the 8086 back in June 1978. The 8086 was one of the first 16-bit processor chips on the market; at the time, virtually all other processors were 8-bit designs. The 8086 had 16-bit internal registers and could run a new class of software using 16- bit instructions. [pic][pic] P2 (286) Processor - In 1982, Intel introduced the Intel 80286 processor, normally abbreviated as 286. The first CPU behind the original IBM PC AT (Advanced Technology), it did not suffer from the compatibility problems that damned the 80186 and 80188.
