2.  What is a processor?
 History
 Intel gives the world i3
 In comes i5
 I7 processor
 Comparison of i3,i5,i7

4.  With the release of the Nehalem
microarchitecture in November
2008,[16] Intel introduced a new
naming scheme for its Core
processors.
 There are three variants, Core i3,
Core i5 and Core i7, but the
names no longer correspond to
specific technical features like the
number of cores.
 Instead, the brand is now divided
from low-level (i3), through mid-
range (i5) to high-end
performance (i7),[17] which
correspond to three, four and five
stars in Intel's Intel Processor
Rating[18] following on from the
entry-level Celeron (one star) and
Pentium (two stars) processors

5. From its early 8-bit beginnings, the Intel architecture now
encompasses a range of 32-bit and 64-bit
microprocessors that address a range of applications,
performance requirements, power levels, and price points.
1971
The first tiny Intel 4004 microprocessor chip
was made

7.  The first Core i3 processors were launched
on January 7, 2010.
 Dual core processor.
 Includes features like hyperthreading, HD
graphics

8. 1.
• The Core i3 is a 3.2 GHz dual core chip, and it's quite
a big improvement over the Core2Duo.
2.
• Low power consumption, with significantly faster
RAM.
3.
• Uses less heat and energy than earlier processors,
which is always a good thing in this day and age.

9.  The Intel Turbo Boost Technology allows a
processor to dynamically increase its clock
speed whenever the need arises. The
maximum amount that Turbo Boost can raise
clock speed at any given time is dependent
on the number of active cores, the estimated
current consumption, the estimated power
consumption, and the processor temperature.

10.  The faster the clock speed in MHz, the faster
each core can run. This can create some
variances in performance. For example, a Core
i3-4370 Haswell processor runs at 3.8GHz. It
would be faster running a single-threaded
application, which can only use one core, than a
Core i5-4590, which only has a clock speed of
3.2GHz. However, running a multi-threaded
application, the Core i5 would most likely be
quicker, as its four real cores are better than the
Core i3's two cores and Hyper-Threading.

11.  Any CPU that has a model ending with a K
means that it the CPU is unlocked. This
means that you can use BIOS settings to up
the clock speed of the chip, overclocking it
yourself. We've seen big improvements in
performance this way - we pushed the Intel
Core i7-4790K chip to 4.7GHz!

12.  Whenever the CPU finds that it keeps on using the same data
over and over, it stores that data in its cache. Cache is just like
RAM, only faster — because it’s built into the CPU itself. Both
RAM and cache serve as holding areas for frequently used data.
Without them, the CPU would have to keep on reading from the
hard disk drive, which would take a lot more time.
 Basically, RAM minimises interaction with the hard disk, while
cache minimises interaction with the RAM. Obviously, with a
larger cache, more data can be accessed quickly. The Haswell
(fourth generation) Core i3 processors have either 3MB or 4MB of
cache. The Haswell Core i5s have either 4MB or 6MB of cache.
Finally, all Core i7 CPUs have 8MB of cache, except for i7-4770R,
which has 6MB. This is clearly one reason why an i7 outperforms
an i5 — and why an i5 outperforms an i3.

14. •I5 provides the opportunity to the users to use the
system with multi tasking.1.
•A big feature of the I5 processors is that they have ability
to run two multitasking processors together that are
generally called as dual processors and can increase the
working performance of the system efficiently.
2.
•I5 processors have ability to work with integrated
memory and can enhance the performance of the
applications. The increase the memory up to 1333 MHz3.

18. With the help of I7 processors users can enjoy the high speed
working with the additional feature of the multitasking i.e. using
two different documents or the files at the same time.
Dual core technology is also a part of I7 processors
that provide reliable and high data rate working
performance to the customers
I7 processors are so advanced to deals with the integrated
memory of e system and have ability to increase the memory up
to 1066 Mbits and provide the working speed of 25.6 GB/sec

25.  This is the mid-size processor of this bunch, recommended for those
who demand a little speed, but not quite enough where the user will
be able to run intensive applications.
 As with the Core i3 processor, this comes with 2-4 cores, the main
difference is that it has a higher clock speed than the Core i3.
 This is also a heat and energy efficient processor, but it does seem to
be better at this particular job than the Core i3.
 The number of threads used in this is no different than the Core i3
with 2-4 threads , it also uses hyper threading technology for a boost
in performance.
 The cache of the Core i5 is bigger than the Core i3.
 The Core i5 is in turbo mode is made available, this provides users
with the opportunity to turn off a core if it’s not being utilized.

26.  This is for the users that demand power,
 The cache on this one is for the users that
demand more cache memory.
 The cache on this one is 4-8 MB.
 This processor comes with 8 threads, definitely
enough to get the job done quickly, maybe even
at the speed of light. And yes it also utilizes
hyperthreading technology.
 You will have four cores to take advantage of
with this particular series.
 And just like the other ones in this Intel series of
processors, it is more energy efficient and
produces less heat.
