Intel core i7 processor

Welcome’s you to new era presented by

Abhishek Ashish

Preface:- The Intel core i7 processor is latest cutting edge process or

with fastest, intelligent multi core technology desktop pc. It delivers four complete execution cores within a single

processor. More instruction can be carried out per clock cycle. Shorter & wider pipelines execute commands more quickly &

improved bus lanes move data throughout the system faster. Overclocking the core i7 processors also seems to be

easier. It is the first processor using Nehalem Micro

Architecture with fastest intelligent, multicore technology that applies processing power where it’s needed most.

New i7 processor deliver an incredible speed through in pc performance.

Content:- Processor CPU Generation of Computers Intel Intel Core Nehalem Micro-architecture Intel Core I7:- 1. Features 2. Specification 3. Advantage & Disadvantage

Processor:- A processor is multipurpose

programmable device, that read binary instruction from memory (it accepts binary data as input) & processed data according to the instruction and provides result as output.

C.P.U:- C.P.U also referred as a “central processor unit”. IT is the

H/W with a computer that carries out the instruction of a computer program by performing the basic arthimatic, logical & input / output operation of a system.

When it was invented in 1960’s it required one or more printed circuit boards, with the invention of microprocessor, a C.P.U could be contained with a single silicon chip.

In 1970’s the microprocessor has almost overtaken all the C.P.U implementation.

Generation of computers:- INTEL 80386:- > first 32 bit microprocessor. > has several mainframe computer feature’s. > semiconductor manufacturing process tech. used is 1.0 micro metre. INTEL80486:- > first intel microprocessor with internal cache memory. > instruction pipeline is more sophisticated than 80386. > semiconductor manufacturing process tech. used from {1.0 to 0.8} micrometre.

Pentium processor (Pentium pro):- > Highly sophisticated compaired to 80486. > it has several new features than that of 80486. >semiconductor manufacturing process technology used is (0.8, 0.6 & 0.35) micro meter. > it is developed by an Indian his name is “Mr. Vinod Dham”.

pentium-2 processor:- > Pentium 2 is a Pentium pro with one chip MMX. > it has 4 power state:- -autohalt -stop grant -sleep -deep sleep > semiconductor manufacturing prcess technology used is (0.3 to 0.25)micro metre.

Pentium-3 processor:- > the dual processing Pentium xenon processor is now available at speed up to 16GHz. > it utilizes a 133 MHz system bus. > semiconductor manufacturing process technology used is (0.25 to 0.18) Micrometre.

Pentium-4 processor:- > the pentium-4 microprocessor is extremely superior microprocessor or based on the Intel net brust micro architecture. > semiconductor manufacturing process technology used is 0.13 micrmetre & (90 nm & 65nm).

Core processor:- > core processor means it having more than one core working simultaneously to complete operation in a time. > it includes “dual core processor” & ”core to dual processor”.

> semiconductor manufacturing process tech. used is 65 nm(nanometre).

Core 2 processor:- > it uses quad core architecture. > as it is quad core so 4 cores working simultaneously. > semiconductor manufacturing processor tech. used is 45nm.

Core i7 processor:- > it also uses four core.> it is fastest processor on the planet.> semiconductor manufacturing processor tech used is 45 nm.

Intel:- intel corporation is an American

multinational semiconductor chip maker corporation.

it’s headquater is in Santa Clara, California.

it is world’s highest & largest semiconductor chip maker.

Founded in july 18,1968.

Intel core:- Intel core is a brand name used for various mid

range to high end consumer & business microprocessor made by INTEL.

Generally, core processor are sold as that it more powerful than that of Pentium & Celeron. Simillarly , identically or more capable versions of core processors are also sold as Xenon processors for the server & workstation market.

From 2013the current lineup of core processor includes the latest Intel core i7, intel core i5 & intel i3

the older are intel core 2 solo, intel core 2 duo, intel core 2 quad, intel core 2 extreme lines.

Nehalem micro architeture:- With the release of the Nehalem micro

architeture in nov,08 , Intel introducing a new naming scheme for its’ core processor.

> core i3 (low level performance) > core i5 (mid level performance) > core i7(high level performance) In Intel’s intel processor:- Celeron Pentium core i3 core i5 core i7

Intel core I7 :- Core i7 is the first processor using Nehalem micro

architecture, with faster, intelligent, multicore tech. that applies processing power where it’s needed most, new intel core i7 deliver an incredible break through in pc performance. They are best desktop family in the planet.

You will done multitasking faster in i7. You will experience maximum performance for every

thing you do. It has a combination of intel turbo boost tech. & Intel

hyper thread tech. with maximize performance to match your workload.
