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..)
 Itincludes 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
 Intelhas 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
 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
 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 (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.
