At some point we all get confuse between core i3, i5 and i7. Today we will cover the difference between them. By the way which processor you are using in your computer? Comment me below….

Basically core i3, i5 and i7 processsors have same fundamental architecture like (sandy bridge, ivy bridge or any new one). Difference between them comes when we compare them on the basis of particular features like hyper-threading, turbo-boost, clock speed and no. of cores available.

When we talk about cores i3 has 2, i5 and i7 have 4 cores. i3 and i7 use hyper-threading technique while i5 doesn’t use it.

When we talk about turbo-boost, i5 and i7 processors use turbo-boost and i3 doesn’t.

So, on the architectural level they all are same but the difference comes when we compare them on the basis of particular features available in the processor.

This is going to be very interesting because in today’s blog I will show you how much area would be occupied by transistors (electronics switch) if they would be replaced by electro-mechanical switches that are used in circuit boards of your home.

We will take AMD Epyc 2017 microprocessor for our calculation which has around 19.2 billion transistors.

Let’s take the area of conventional switch of measurement as length is 3 cm and breadth is 1 cm. So the surface area would be 3*1= 3 cm^2 ( 3 cm square)

Delhi’s surface area 1484 km^2 . So the ratio will be as follows.

Ratio= (area of conventional switch* total no. of transistors in microprocessor)/ surface area of Delhi.

Note: Here I am changing the surface area of delhi from km^2 (km square) to cm^2 (cm square)

= (3 x 19.2x 10^12 )/ 1484x 10^10

= 3.88 times of Delhi. Means you will require 3.88 times of Delhi surface area to put the no. of transistors used in AMD Epyc 2017 microprocessor.

Isn’t looking great how much excellently electronics is changing the world by improvements on the daily basis.

If we will do further calculation, then also can find out how many AMD Epyc 2017 microprocessors would be required to cover the whole earth if the transistors will be replaced by conventional switches.

Planet Earth surface area (cm^2)= 510x 10^12 cm square.

So only around 900 microprocessors would be required to cover the Earth.

I think you all must heard about hyper threading technique. Intel and other microprocessor vendors uses hyper-threading to enhance the performance of processor. Mostly hyper-threading is used in video editing, 3-D rendering, heavy multi-tasking etc.

Intel’s core-i3 /i7 use hyper-threading while core–i5 doesn’t.

In this technique we can virtually double the number of cores the actual processor has. So the efficiency of the processor increases very much.

You can think it like this if you have only one hand and you are eating candies. You will take one candy in one hand and take it the mouth chew and take second candy and chew and continue in the same manner. Now what is happening here is you are wasting time in picking up the candy because the process of chewing candy is very fast in comparison to picking up the candy.

But if you will use both hands, when you will chew candy put by one hand, you can have candy in the other hand for eating. So it will look like that there is no delay during eating and your mouth could do its job continuously without stopping.

Here your mouth is a processor and hand are data lines and candy is a data.

So, in hyper-threading it will look like that you have double the number of processors (virtually) because the single processor is handling the data of two lines.

I hope now you have understood this technique. Thanks for reading. Like, comment and share this post. 

Turbo boost is an Intel’s technology in which processor can automatically overclock its speed so that the processing speed could be reached to the maximum level.

Intel’s core-i5 and core-i7 processors use turbo boost while core-i3 doesn’t has this feature.

But the question is, is it safe for processor to run at over-clock?

The answer is yes, the CPU constantly checks the temperature and other parameters and when the temperature is quite low it over-clocks the processor and when temperature becomes quite high it again lowers the clock speed to the original clock frequency.

Thus we can achieve the maximum efficiency from the processor using turbo-boost.

Ransom wares are the malwares that are designed to attack the computer systems and lock them in a way that you will need a passcode to unlock the system. The hacker could ask you any amount for this passcode, but even after paying the money their is no guarantee that he will unlock your system. So as you know precaution is better than cure, here are 5 tips that will help you to remain safe from these attacks.

• Keep your antivirus up-to-date
• Don’t open un-trusted or unknown mail attachments
• Run antivirus in heuristic mode
• Always make sure that you are taking your data’s backup at least once a week in a external hard drive or cloud system
• Update operating system so that new virus, malware and Trojan definitions can be modified on your system

I hope you guys will apply these tips and remain safe from these types of attacks. Share these tips.
