Launch of i7 Processor:

Intel representatives state that Core i7 is meant to help consumers decide which processor to purchase as the ner Nehalem-based products are released in the future. The name continues the use of the Intel Core brand. Core i7, first assembled in Costa Rica, was officially launched on November 17, 2008[11] and is manufactured in Arizona, New Mexico and Oregon, though the Oregon (PTD, Fab D1D) plant has already moved to the next generation 32 nm process.

Product information:

• 3.06 GHz, 2.93 GHz, and 2.66 GHz core speed • 8 processing threads with Intel HT technology • 8 MB of Intel Smart Cache • 3 Channels of DDR3 1066 MHz memory

Intel officially unveiled all details regarding its Core i3, Core i5 and Core i7 Mobile as ll as Desktop processors in CES 2010. The introduction of new chips coincides with the arrival of Intel’s new 32 nm architecture, manufacturing process and integration high-definition graphics inside the processor. It is the successor of the 45 nm architecture.

Intel is expecting good results from better-integrated graphics of the Core i3 and i5 processors, as the sales in the last two years re rather flat. The new “Arran dale” graphics technology has 20% more shades which is an important component for 3D graphics, Intel senior vice president Sean Maloney said. Intel claims that the graphics performance is roughly 70% better than the integrated graphics in the current Core 2 Duo.

ABOUT PROCESSOR

The Central Processing Unit (CPU) or the processor is the portion of a computer system that carries out the instructions of a computer program, and is the primary element carrying out the computer's functions. This term has been in use in the computer industry at least since the early 1960s. The form, design and implementation ofCPUs have changed dramatically since the earliest examples, but their fundamental operation remains much the same.

� TheCPU (Processor) is the brain of every computer. Every calculation and process made by a computer is executed by theCPU. � The processor performs calculations by using bits (definition of bit), which can have a value of 1 or 0. � The most common processor is a 32-bit, but 64-bit processors are becoming more popular in ner computers. � Moore's Law from 1965 predicts that processing por should double every 18 months, but was revised in 1975 to every 2 years. This prediction was made on the basis that the circuitry, resistors, and other processor parts are being made smaller and smaller. � Currently, an average CPU can have processing speeds from about 2.0 GHz to 3.4 GHz, with the manufacturers fast approaching the 4.0 GHz mark.

Early CPUs re custom-designed as a part of a larger, sometimes one-of-a-kind, and computer. Hover, this costly method of designing custom CPUs for a particular application has largely given way to the development of mass-produced processors that are made for one or many purposes. This standardization trend generally began in the era of discrete transistor mainframes and minicomputers and has rapidly accelerated with the popularization of the integrated circuit (IC).

The design complexity of CPUs increased as various technologies facilitated building smaller and more reliable electronic devices. The first such improvement came with the advent of the transistor. Transistorized CPUs during the 1950s and 1960s no longer had to be built out of bulky, unreliable, and fragile switching elements like vacuum tubes and electrical relays.

A method of manufacturing many transistors in a compact space gained popularity. The integrated circuit (IC) allowed a large number of transistors to be manufactured on a single semiconductor-based die, or "chip." At first only very basic non-specialized digital circuits such as NOR gates re miniaturized into ICs. CPUs based upon these "building block" ICs are generally referred to as "small-scale integration" (SSI) devices.

TYPES OF PLATFORMS

Mobile Platform:

Just three months after their Developer Forum 2009 in September, Intel has introduced new dual-core 2.66GHz Intel Core i7-620M processor with TDP rating of 35W. Four other dual-core Intel Core i7 chips re introduced of which two are for low-voltage family (2.0GHz Core i7-620LM and 2.13GHz Core i7-640LM) and other two are for ultra-low voltage family (1.06GHz Core i7-620UM and 1.2GHz Core i7-640UM).

Both pairs of low-voltage and ultra-low voltage processors will offer Intel Turbo Boost Technology to increase the performance. The low-voltage Intel Core i7 mobile chips have TDP rating of 25W while the ultra-low Core i7 chips have TDP rating of 18W.

Two new Intel Core i3 and three new Core i5 mobile processors re also unveiled at the same time. Out of these the new Core i3 processors are clocked beten 2.13GHz for Core i3-330M and 2.26GHz for Core i3-350M. Both processors have Thermal Design Poor rating of 35W. These Core i3 are mostly made for light-light notebooks but won’t offer Intel Turbo Boost Technology to increase the CPU clock speed for higher performance.

.

OPERATION OF PROCESSOR

�Control Unit (CU) controls the sequence of instructions to be executed and it also manages the flow of data to and from other parts of the computer for instance the internal parts, like memory, or the external parts like a hard drive. It interprets instructiming of the processor.

�Arithmetic and Logic Unit (ALU) are two units that perform different operations, but in similar operations. The Arithmetic unit processes the data for math purposes or for additional processing like combination or deletion or interruption processes. That is done with the logic unit.

�Registers are special memory elements used by the CPU for storing data temporarily during execution of instruction. For instance, the Instruction Register (IR) holds the executed. Meanwhile the Process Status Register holds "processor bit" about operations done by ALU. These registers are pseudo memory modules; useful because they don't have to leave the CPU so they are in the same "room" when the ALU or

3) Execute: During this step, various portions of the CPU are connected so they can perform the desired operation. If, for instance, an addition operation was requested, an arithmetic logic unit (ALU) will be connected to a set of inputs and a set of outputs. The inputs provide the numbers to be added, and the outputs will contain the final sum. The ALU contains the circuitry to perform simple arithmetic and logical operations on the inputs

4) Write back: Simply "writes back" the results of the execute step to some form of memory. Very often the results are written to some internal CPU register for quick access by subsequent instructions. In other cases results may be written to slot, but cheaper and larger, main memory. Some types of instructions manipulate the program counter rather than directly produce result data. These are generally called "jumps" and facilitate behaviours like loops, conditional program execution (through the use of a conditional jump), and functions in programs. Many instructions will also change the state of digits in a "flags" register.

DESIGN AND IMPLEMENTATION

The way a CPU represents numbers is a design choice that affects the most basic ways in which the device functions. Some early digital computers used an electrical model of the common decimal (base ten) numeral system to represent numbers internally. A few other computers have used more exotic numeral systems like ternary (base three).

Nearly all modern CPUs represent numbers in binary form; with each digit being represented by some two-valued physical quantity such as a "high" or "low" voltage related to number representation is the size and precision of numbers that a CPU can represent. In the case of a binary CPU, a bit refers to one significant place in the numbers a CPU deals with. The number of bits (or numeral places) a CPU uses to represent numbers is often called "word size", "bit width", "data path width", or "integer precision" when dealing with strictly integer numbers (as opposed to floating point). This number differs beten architectures, and often within different parts of the very same CPU.

PERFORMANCE OF PROCESSOR

--The performance or speed of a processor depends on e.g. the clock rate and the Instructions per Clock (IPC), which together are the factors for the Instructions Per Second (IPS) that the CPU can perform.

-- Many reported IPS values have represented "peak" execution rates on artificial instruction sequences with few branches, whereas realistic workloads consist of a mix of instructions and applications, some of which take longer to execute than others.

--The performance of the memory hierarchy also greatly affects processor performance, an issue barely considered in MIPS calculations.

--Because of these problems, various standardized tests such as secant have been developed to attempt to measure the real effective performance in commonly used applications.

--Processing performance of computers is increased by using multi-core processors, which essentially is plugging two or more individual processors (called cores in this sense) into one integrated circuit.

-- Ideally, a dual core processor would be nearly twice as porful as a single core processor. In practice, hover, the performance gain is far less, only about fifty percent, due to, e.g. imperfect software algorithms and implementation.

RAM Vs PROCESSOR

�Often, the first thing which comes to our mind when thinking of upgrading our computer are either adding more memory modules (RAM) or going for a faster processor (CPU).

� The main reason is that these two components form the very basic core of a machine, allowing it to store program instructions (gathered from your hard drive) and subsequently access and process these via the CPU.

�When considering an upgrade both components are important. Of course it isn’t always possible to upgrade both RAM and the CPU at the same time, the latter obviously being the most costly.

� Adding more RAM to system doesn’t hurt and, if the system requires, will certainly notice an improvement.

Intel Core i7 Processor Seminar Report 2013

Page | 13

Department of Computer Applications

�It isn’t recommended that upgrade one component if all the rest is terribly outdated compared. Won’t notice any improvements and old technology won’t be able to make use of improved.

Random Access Memory (RAM)

As briefly stated in the previous paragraphs, RAM is the area of your computer which stores information required by your operating system, games, video/audio and other programs. This information typically needs to be accessed quickly and it is possible, thanks to a processing unit (i.e. your CPU or one present on a graphics card for instance), for any of this information to be gathered at any one time: hence the word “Random” in the acronym. RAM is also volatile, which means it will be flushed each time you turn your computer off.

This is where random access differs from serial access, where one needs to search through from the very beginning in order to access the required information. Magnetic tape is an example of serial access.

It is important to point out that RAM cannot process information but can only serve as storage. Upgrading your computer with more or larger storage RAM modules will not add more system resources for processing information or allow you to run more than one processor intensive application (as in the case of hyper-threading or a multi-core CPU).

Central Processing Unit

The CPU is the brain of your machine which gathers information, via the control unit, from your installed memory modules, and processes instructions, via the logic unit, in order to run your programs. The CPU comes with varying clock speeds, which determine the number of instructions executable per second, and many other features which allow for faster and smoother execution. A faster-clock CPU installed in your machine will allow you to perform these calculations and instructions faster, which in practical terms means being able to quickly access programs, read memory and execute the functions within those programs. For example, in a video conversion operation (converting one format to another), the processing times will be much less if you have a dual-core processor installed. When using a program like Photoshop or Paint Shop Pro, the effects you apply to an image use processing pore also.

processors in applications that only use one or two cores. For more in-depth information, read a full review of the Core i5's performance.

Triple-Channel DD3 and Dual-Channel Memory:

- The original Core i7 products, and their associated X58 chipset, make use of triple-channel DDR3 memory. This meant that it was best to purchase RAM sticks in multiples of three.

- This is a turn off to many users because it makes RAM less flexible and requires more spending upfront. Gamers may enjoy spending the money to see the i7 really perform.

-Core i5, however uses traditional dual-channel memory. This should make RAM less expensive for most users. Some new Core i7s will also support dual-channel memory instead of triple-channel. The performance difference should be insignificant for most users.

Difference in Hyper-Threading:

- Another significant performance difference is how the Core i7 and Core i5 products will be handling hyper-threading. Hyper-threading is a technology used by Intel to simulate more cores than actually exist on the processor.

- While Core i7 products have all been quad-cores, they appear in Windows as having eight cores. This further improves performance when using programs that make good use of multi-threading.

-Some Core i5 products have this feature, but some do not. Currently, the Core i5 750 does not have hyper-threading, but it does have four physical cores. The dual-core Core i5 products, on the other hand, do have hyper-threading.

Multi-graphics:

Another significant change with the Core i7/X58 landscape had to do with graphics cards. Intel's Skull trail platform of last year supported both standards as ll, but the specialized CPUs that made the board worthwhile re prohibitively expensive.

- With the X58 chipset, yes, it comes on an expensive motherboard, but you can purchase a Core i7 chip to go with it for less than $300. The Core 2 Extreme QX9775 Skull trail CPU started at $1,500.

-- In fact, tested it with 1600 MHz memory, since this is a more likely configuration for a thousand-dollar processor.

-- For a CPU, the bandwidth numbers involved here are considerable. Three channels of memory at 1066 MHz can achieve an aggregate of 25.6 GB/s of bandwidth.

-- At 1333 MHz, you're looking at 32 GB/s. At 1600 MHz, the peak would be 38.4 GB/s, and at 2000 MHz, 48 GB/s.

-- By contrast, the peak effective memory bandwidth on a Core 2 system would be 12.8 GB/s, limited by the throughput of a 1600MHz front-side bus.

--With dual channels of DDR2 memory at 1066MHz, the Phenom's peak would be 17.1 GB/s.

-- The Core i7 is simply in another league. In fact, our Core i7-965 Extreme test rig with 1600MHz memory has the same total bus width (192 bits) and theoretical memory bandwidth as a GeForce 9600 GSO graphics card.

gains. The added processor threads and L3 Smart Cache will certainly help boost performance in Virtual Machine and VM Ware environments, or professional design suites such as Adobe Photoshop and Premiere-Pro, Auto Desk Maya and 3DS-Max, Microsoft Excel and Windows Live Movie Maker, Sony Vegas and Acid, and also Virtual Dub.

Gaming performance is solely dependant on the GPU when it comes to enthusiast hardware, and no amount of processor cores will improve what ATI or NVIDIA have already created in their products.

Overclockers may be sorely disappointed if they expect the 980X to beat the i7-975 to 5 GHz, because the extra cores make this chip a little less nimble when it comes to dancing around boundaries. Ultimately the Intel Core i7 is not meant to be a value-driving SKU, and the PC-hardware elite have always understood this. Much like Lexus automobiles, which are little more than decorated Toyota's, Intel saves the bells and whistles for their exclusive Extreme Edition product line.
