Intel i3 Vs Intel i5 Vs Intel i7 Introduction.

Intel Core i3

Intel Core i5

Intel Core i7

Comparison among i3, i5 and i7.

Conclusion.

Westmere

Its Intel’s code-name for Core i3 and

Core i5 6xx processors.

Its 3rd generation of Intel’s Nehalem

architecture.

Major differences :

It’s built on 32nm manufacturing

processor.

Advantage : Lower power consumption

and Reduced size.

Westmere (cont..)

It includes SSE (Streaming SIMD

Extensions) instructions aimed at

accelerating encryption and decryption

with the AES algorithm.

Westmere is largely the same as previous

Nehalem processors with slight

variations.

The IGP : Clarkdale

Intel has IGP onto the same die as the

CPU.

They are still separate entities, but they

are kept on the same piece of hardware.

This combination results are not so

exciting as they sound.

Real advancement is the inclusion of

support for Dolby True HD and DTS HD-

MA bit streaming over HDMI.

The IGP : Clarkdale(cont..)

Due to that, Core i3 based system could

play any kind of movie you throw at it,

including Blu-Rays, without performance

issues and without running into problems

with Blu-Ray encryption.

Intel Core i3

Codenamed: Clarkdale (Westmere)

Fabrication: 32 nm

Instruction set: X86, X86-64, MMX, SSE

4.2

Socket: LGA 1156

Bus: Direct Media Interface replacing

FSB( Front Side Bus)

RAM: DDR3

Chipset Support: P55, H55, H57, Q57

Intel Core i3 (cont..)

Clock speeds : 2.93 to 3.06 GHz.

Cache : 2X256 KB L2 and 4MB L3 .

Supports Hyper Threading

Has an Integrated graphics processor.

These don’t support Turbo Boost

(Dynamic over-clocking).

Hyper Threading

It is a technology used by Intel to simulate

more cores than actually exist on the

processor.

It also improves performance when using

programs that make good use of multi-

threading.

Intel Core i5

Codenamed: Lynnfield (Nehalem),

Clarkdale (Westmere)

Fabrication: 45 nm, 32 nm

IS: X86, X86-64, MMX, SSE 4.2

Socket: LGA 1156

Bus: Direct Media Interface

RAM: DDR3

Chipset Support: P55, H55, H57, Q57


Two types

1. Dual Core (similar to Core i3)

II. Quad Core (Much Closer to Core i7)

DualCore Core i5 :

Architecture : Clarkdale (Westmere)

Fabrication : 32nm

Sockets : LGA 1156

BUS : DMI

Dual Core i5 (cont..)

Clock Speeds : 3.2 to 3.6 GHz.

Cache : 2x256 KB L2 and 4MB L3

Has Integrated Graphics Processor

Include Turbo Boost.

Supports Hyper Threading.

Quad Core i5

Architecture : Lynnfield (Nehalem)

Fabrication : 45nm

Socket : LGA 1156

BUS : DMI

Two Processors with Clock Speeds of 2.4 and 2.66 GHz.


Supports Turbo Boost.

Don’t support Hyper Threading and have No Integrated Graphics Processor.

Intel Core i7

Codenamed: Bloomfield (Nehalem)

Fabrication: 45 nm

Instruction set: X86, X86-64, MMX, SSE

4.2

Socket: LGA 1366

Bus: Quick Path Interconnect

RAM: DDR3

Chipset Support: X58


They offer the Best Performance.


They support Turbo Boost and Hyper

Threading(8 virtual cores)

Don’t have an Integrated Graphics

Processor.

Core i3 Vs Core i5 Vs Core i7

Core i3 Vs Core i5 Vs Core i7 (cont..)

Core i3 Vs Core i5 Vs Core i7 (cont..)

Performance : Besides being multi-core, Hyper Threading technology combined with the Turbo Boost makes i3, i5 and i7 to be computing power houses.

For gaming, core i7 processors win hands due to their phenomenal processing power.

Even Core i5’s are good enough but if you want raw power then its good to go for i7.

Core i7 is much faster due to the QPI , Hyper Threading and Turbo Boost.

Cost :

Core i3 are priced at $133 only while Core i5 are priced at $176 to $256 and Core i7 are priced in the range $200 to $1000.

Which is better for whom?

If you are into an entry level system its good to go for core i3 line. It’s great for home use desktop computers too.

Core i5 line is ideal for the business user or home users, who are into normal gaming.

If you want your system to be almost like a server with super computing power at your finger tips go for i7 (Best processor yet on the earth).

Note : Choose that suits your budget and computing requirements.

Conclusion

Intel core i3, i5 and core i7 are the best

series of processors yet in the present

market.

Intel core i7 is the Best processor ever

on the earth as of now.

Intel sustains its value and dominated the

market coming up with this successful

series of Core i3, Core i5 and Core i7.

Thank You
