The document discusses the differences between Intel i3, i5, and i7 processors, including explanations of key concepts such as core, clock speed, cache memory, turbo boost, and hyper-threading. It provides comparison charts for both desktop and laptop editions, highlighting factors like the number of cores, clock speed range, availability of hyper-threading, turbo boost capabilities, and cache memory size. Overall, it guides users in choosing the appropriate Intel processor based on their needs.

3. What should we choose?
Intel i3 || Intel i5 || Intel i7

4. Before going further……..
Let’s discuss few fundamental entities…
What do you mean by Core?
What is Clock Speed?
What is Cache Memory?
What is Turbo Boost?
What is Hyper-Threading?

5. What is Core in a Processor?
• A core is a unit frequently known as Central
processing unit (CPU) which is responsible for
executing our computational tasks.
• Example:
• A Dual Core has 2 CPU.
• A Quad Core has 4 CPU.
• An Octa Core has 8 CPU.

6. What is Clock Speed in a
Processor?
• Speed of a Processor is determined by clock
cycle.
• Clock cycle is amount of time between two
pulses of an oscillator.
• Higher the clock speed, the faster the
processor will able to execute the processes.
• Clock speed is measured in Mega hertz (MHz)
or Giga Hertz (GHz).
• Ex: 2.3 GHz , 3.4 GHz, 4.1 GHz.

7. What is Cache Memory?
• It is a small amount of memory built into the
processor that consists of data stored in main
memory (RAM).
• It is a high speed memory (almost as faster as CPU).
• Very Expensive.
• More the Cache, the faster is your processor.

8. What is Turbo Boost Technology?
• Turbo boost feature dynamically increases the
clock speed of CPU when more power is
required.
• It enhance the clock speed of CPU.
• Whenever the higher clock is required due to
some heavy work, CPU can attain it by over
clocking the speed.
• Only Intel i5 & i7 (Desktop) processor have
this feature.

9. What is Hyper-Threading Technology?
• Hyper-Threading tricks the operating system
(ex- MS Windows/Linux) such that each
physical processor core appears as two
virtual (logical) cores.
• Available in Intel i3 & i7. Not available in i5.
• Beneficial for multi-threaded applications.
