Intel Processor Explained 

Are you someone who is planning to purchase a laptop? If yes, then technical terms of the Intel Processor must confuse you. What is the difference between i3, i5, or i7 Processor? What is the core? Is hyperthreading is important? Is generation matter? The answers to all these questions are here.


Almost everyone is heard about computers either he is from a technical background or not. Every field requires computers/laptops. Even children need a computer/laptop.

Mainly computer consists of many types of hardware. The processor is one amongst them. Before 40-50 years ago Computers generally came with a single processor. Here we are not talking about a supercomputer or a special purpose computer. We are just talking about general-purpose computers that most of the peoples are using.
The processor mainly consists of three units.
1.  Memory Unit 
2.  Arithmetic and Logical Unit.
3.  Control Unit.
Intel Core i7

Every program that you want to run goes to Processor. Every command or instruction proceeds in the processor. On excessive commands processor becomes slow. So people think to add more processors in a CPU. It definitely helps in increasing the speed of the Processor but its manufacturing cost increases.

In the solution of this Intel introduce the concept of Core. In this concept, two or more processors are combined to form a single processor. Intel introduced these new processors after Pentium 4 that was Core 2 duo or dual-core. Then after this, as time spent Intel introduce i3, i5, i7, or i9. These all processors have dual-core, quad-core, or more.


The concept of hyperthreading is introduced by Intel. It is introduced firstly in the Pentium 4 processor of Intel. Now it is in almost all Intel processors. Basically, hyperthreading converts single core into double core and double core into quad-core virtually and logically. So it is very good for any processor.


The main important component of any processor is a transistor. The size of this transistor always reduced with an increase in generation. It means it can help in reducing the size of the processor. So the power consumed by the processor will reduce. It is most useful for battery-powered laptops. It means your laptop battery life will increase. Now at the present time, we have the latest 10th generation processor.

In the starting days of intel that is between 1971-1972 the size of intel processors was about10,000 nanometer, now it is reduced to 10 nanometers. This is extremely small you can not see by naked eyes.

32 or 64 Bit:

  • There exist two types of processors. A 32 bit CPU can access 2³² memory addresses and a 64-bit CPU 2³² * 2³² memory address. 64-bit system is handled by above 4 GB RAM.
  • The difference between 32-bit and the 64-bit system is the number of calculations per second they can perform.
  • Without hanging 64-bit system can perform many tasks than a 32-bit system.
  • High-end software like Photoshop, CAD, etc. takes lots of memory, can run easily on a 64-bit system.

  • A 64-bit computer can have a 64-bit or 32-bit operating system.
  • However, in a 32-bit system, a 64-bit system can not run with full compatibility.
  • Commonly these days we are seeing Intel processors in all the laptops That's why today we will be discussing "Which processor you should choose for your laptop" and also we will be discussing different generations of processors from Intel lineup.
  • If you are someone confused about what processors to choose for your laptop. and what all are the number that's coming after it's model number, you are not alone. I really have no idea what's Intel's intentions where But they have made it pretty difficult for a normal guy to remember all these numbers and what it really means.

Intel i3:

In low budget laptop segment apart from few Pentium processors we are seeing commonly core i3 as the processors on these laptops. and this is for a casual user who would like to watch movies listen to some music, do a casual web browsing and also read some word documents. and if you look at the specification of this processor 

They are coming mainly in two variants. One with 2 cores and hyper-threading enabled in this case the CPU will treat this as 4 core processors. and the other variant is 4 cores without hyper-threading enabled.

As per the naming convention of the processor, we will be seeing several versions of core i3. For example. CORE i3 7350K In this name, we have to notice two things, 7 and the K 7 - is the generation of the processor it is using. K - will stand for the specific behavior of the processor.

So here I will explain few commonly seen alphabet and what it actually means. The alphabet K -means it enables itself to overclock. if the motherboard allows it to. and there is another alphabet U. which means ultra-low power. which means its very power efficient. and there is another alphabet X. Which is only seen in core i9. Which indicates a very high-end processor.

Coming back to core i3. You can play some low-end graphics games in this Core i3 But if you want to perform more, it will definitely disappoint you. But at this price segment, you can't complain about it. So if your requirement is a bit more and you are someone who would like to do some coding bit Photoshop editing and mid-level gaming You should consider Core i5

Intel i5:

In Core i5, mainly 3 variants are there. The 6-core variant with hyper-threading not enabled. and there is 4 core variant with hyperthreading enabled and there is a 2 core variant with hyperthreading enabled. Which is mainly seen in ultrabooks and mobile platforms. 

In core-i5 compared to core i3, you can see more cache, also more clock speeds. which will be more expensive compared to the i3 variant in the same generation.

Intel i7:

Talking about expensive, we have next-level processor "i7" If you are someone who would like to do some video editing or rendering. or play some high-end games and crazy resource-consuming software Then you should consider Core -i7 In this processor mainly 3 variants are present. 2 core, 4 core, and 6 core variants. In all the variants, hyper-threading is enabled. and for the highest variant for the i7 we have 12 megabytes of cache, which is higher than the core -i5 counterpart. and which will also perform more powerful and faster than core i5 

Intel i9:

If you want to go even higher. Intel has one more option. Core -i9, in which we have 10, 12, 14, 16 and 18 core variants In all the variants we have hyper-threading enabled. For a normal user, this is the sky in terms of performance and price


So now we know what is i3, i5, and i7 and which processor to choose for your laptop. Now let's walk into different generations of these processors. With each new generation of these processors, they are improving the technology with which they are developing these processors.

The latest generation as of now it is 10th Gen is developed using a 10 nm technology. Which will be very power efficient and also very powerful in an overall perspective?
