The Intel i7 Processor

Intel Core i7 is Intel's brand name for several families of desktop and laptop 64-

bit x86-64 processors using the Intel Nehalem micro architecture. It is a suc-

cessor to the Intel Core 2 brand. The Core i7 identifier was first applied to the

initial family of processors codenamed Bloomfield introduced in 2008. In 2009

the name was applied to Lynnfield and Clarkefield models. Prior to 2010, all

models re quad-core processors. In 2010, the name was applied to dual-core Ar-

ran dale models, and the Gulf town Core i7-980X Extreme processor which has

six hyper threaded cores.

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 manufac-

tured in Arizona, New Mexico and Oregon, though the Oregon (PTD, Fab D1D)

plant has already moved to the next generation 32 nm process.

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 pro-

cess and integration high-definition graphics inside the processor. It is the suc-

cessor 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 compon-

ent 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 becom-

ing 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.

The Intel i7 Processor

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-pro-

duced processors that are made for one or many purposes. This standardization

trend generally began in the era of discrete transistor mainframes and minicom-

puters and has rapidly accelerated with the popularization of the integrated cir-

cuit (IC).

The design complexity of CPUs increased as various technologies facilit -

ated building smaller and more reliable electronic devices. The first such im-

provement 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 fra-

gile 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 in-

troduced 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

What's Inside a CPU?

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 in-stance the internal parts, like memory, or the external parts like a hard drive. It interprets instructions and it regulates the timing of the processor.

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

The Seminar Report Page 16

The Intel i7 Processor

Registers are special memory elements used by the CPU for storing data tem-porarily during execution of instruction. For instance, the Instruction Register (IR) holds the instruction being executed. Meanwhile the Process Status Re-gister 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 Control unit needs them again.

The Program Counter (PC) holds the address of next instruction to be ex-ecuted. While the Instruction Decoder is a device which interprets the instruc-tion to be executed. Accumulator (ACC) stores intermediate and final results of calculation. It's the main working area of ALU.

The Seminar Report Page 17

The Intel i7 Processor

The fundamental operation of most CPUs, regardless of the physical form they

take, is to execute a sequence of stored instructions called a program. The pro-

gram is represented by a series of numbers that are kept in some kind of com-

puter memory. There are four steps that nearly all CPUs use in their operation:

fetch, decode, execute, and write back.

1) Fetch: It involves retrieving an instruction (which is represented by a num-

ber or sequence of numbers) from program memory. The location in program

memory is determined by a program counter (PC), which stores a number that

identifies the current position in the program. In other words, the program

counter keeps track of the CPU's place in the current program. After an instruc-

tion is fetched, the PC is incremented by the length of the instruction word in

terms of memory units.

2) Decode: The instruction that the CPU fetches from memory is used to de-

termine what the CPU is to do. In the decode step, the instruction is broken up

into parts that have significance to other portions of the CPU. The way in which

the numerical instruction value is interpreted is defined by the CPU's instruction

set architecture (ISA). In older designs the portions of the CPU responsible for

instruction decoding re unchangeable hardware devices.

The Seminar Report Page 18

The Intel i7 Processor

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 in-

puts 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 re-

gister 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" re-

gister.

The Seminar Report Page 19

The Intel i7 Processor

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 com-

puters 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 of-

ten 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 Instruc-

tions Per Second (IPS) that the CPU can perform.

-- Many reported IPS values have represented "peak" execution rates on artifi-

cial instruction sequences with few branches, whereas realistic workloads con-

sist of a mix of instructions and applications, some of which take longer to ex-

ecute than others.

--The performance of the memory hierarchy also greatly affects processor per-

formance, 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 com-

monly used applications.

The Seminar Report Page 21

The Intel i7 Processor

--Processing performance of computers is increased by using multi-core pro-

cessors, 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.

The Seminar Report Page 22

The Intel i7 Processor

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.

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.

The Seminar Report Page 23

The Intel i7 Processor

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/au-

dio 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 informa-

tion. 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 al-

low 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 Seminar Report Page 24

The Intel i7 Processor

The CPU is the brain of your machine which gathers information, via the con-

trol 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 pro-

cessor installed. When using a program like Photoshop or Paint Shop Pro, the

effects you apply to an image use processing pore also.

i5 PROCESSOR Vs i7 PROCESSOR

The Seminar Report Page 25

The Intel i7 Processor

The new Core i5 processors re released in September 2009. As the name would

suggest, these processors do not represent a new architecture but rather a main-

stream release of processors based on the Nehalem architecture, which re previ-

ously available only as part of the Core i7 line. Of course, the marketing of the

new products indicates that they are intended to be seen as less capable products

than the existing Core i7 processors.

The New Socket and Chipset:

One of the most importance differences between Core i5 and Core i7 is the use

of a new socket, known as LGA1156. This new socket will also be used by

some Core i7 products, but current Core i7s use the LGA1366 socket. The new

LGA1156 socket is partnered with a new chipset, the P55. As those who follow

computing would guess, the P55 is

designed as a mainstream chipset.

This means fewer features, but lot

cost.

Turbo Mode:

- One feature which will be re-

sponsible for a major performance

difference is the improvements in

turbo mode. The original Core i7

The Seminar Report Page 26

The Intel i7 Processor

processors came with a turbo mode which allowed the processor to essentially

over-clock itself automatically when some cores re not being used.

- The Core i7-965, for example, could hit 3.46 GHz when the turbo mode was

fully active. Its stock speed is 3.2 GHz.

- Intel has said this will be enhanced with the new Core i5 products as ll as with

the new Core i7 860 and 870. The Core i5 750, for example, should be able to

accelerate from its stock speed of 2.66Ghz to speeds as high as 3.2Ghz.

- This is a substantial improvement, and it allows new Core i5 processors to per-

form as ll as current Core i7 processors in applications that only use one or two

cores. For more in-depth information, read a full review of the Core i5's per-

formance.

Triple-Channel DD3 and Dual-Channel Memory:

The Seminar Report Page 27

The Intel i7 Processor

- 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 re-

quires 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.

The Seminar Report Page 28

The Intel i7 Processor

-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.

- Gamers who stay current with graphics cards should be especially happy with

this flexibility, as changing 3D card vendors will no longer require a wholesale

system rebuild.

The Seminar Report Page 29

The Intel i7 Processor

-- One mechanism Intel uses to make its caches more effective is prefetching, in

which the hardware examines memory access patterns and attempts to fill the

caches speculatively with data that's likely to be requested soon.

-- Intel claims the Core i7's prefetching algorithm is both more efficient than

Penryn's—some server admin wound up disabling hardware prefect in Xeons

because it harmed performance with certain workloads, a measure Intel says

should no longer be needed—and more aggressive, as ll.

The Seminar Report Page 30

The Intel i7 Processor

--The Core i7 can get to main memory very quickly, too, thanks to its integrated

memory controller, which eliminates the chip-to-chip "hop" required when go-

ing over a front-side bus to an external north bridge.

-- Again, this is a familiar page from AMD's template, but Intel has raised the

stakes by incorporating support for three channels of DDR3 memory.

-- Officially, the maximum memory speed supported by the first Core i7 pro-

cessors is 1066 MHz, which is a little conservative for DDR3, but frequencies

of 1333, 1600, and 2000 MHz are possible with the most expensive Core i7, the

965 Extreme Edition.

-- In fact, tested it with 1600 MHz memory, since this is a more likely configur-

ation 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.

The Seminar Report Page 31

The Intel i7 Processor

-- 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 theoret-

ical memory bandwidth as a GeForce 9600 GSO graphics card.

The Seminar Report Page 32

The Intel i7 Processor

CONCLUSIVE REPORT

The first is performance, which considers how effective the Intel Core i7 pro-

cessor performs in operation against similar desktop products. While any con-

spicuous benefits to video game performance, it didn't harm frame rate, either.

The new 32nm Westmere micro architecture reduces power drain down to only

12W at idle, which is a 'Green' step in the right direction and conserves energy.

Several architectural design

and micro architectural

functionality enhancements

have been added to the Intel

Core i7-980X, including six

processor cores in the CPU

package and increased

shared cache memory buf-

fer. The codename

Gulftown multi-core pro-

cessor utilizes an integrated memory controller technology and uses up a 130-

Watt thermal design power (TDP).

The Seminar Report Page 33

The Intel i7 Processor

The i7 processor features an Intel QPI point-to-point link capable of up to 6.4

GT/s, 12 MB Level 3 cache, and an integrated triple-channel memory control-

ler. Other than two new CPU cores, which yield four additional processor

threads and 2MB L3 Smart Cache each, the new Gulftown 980X also brings

twelve additional Advanced Encryption Standard New Instructions (AES-NI) to

the Core-i7 family. Gulftown supports all the existing Streaming SIMD Exten-

sions 2 (SSE2), Streaming SIMD Extensions 3 (SSE3) and Streaming SIMD

Extensions 4 (SSE4). The Intel Core i7-980X also processor supports several

Advanced Technologies: Intel 64 Technology (Intel-64), Enhanced Intel Speed

Step Technology, Intel Virtualization Technology (Intel-VT), Turbo Boost

Technology, and

In conclusion, Intel Core i7 processor satisfies that insatiable need for enthusi-

asts to own a slice of the impossible. Tests have shown that computational tasks

such as media transcoding and compression archiving, and especially encryp-

tion, have all seen impressive 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.

The Seminar Report Page 34

The Intel i7 Processor

Gaming performance is solely dependant on the GPU when it comes to enthusi-

ast 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.
