What is a 7nm process?

where it is used ? which phones are using it? Does it matter?

This image shows the specifications of A13 bionic chip (World’s best mobile processor used in iphone 11 ) . Notice the process portion and what does that 7nm mean? let’s check it out.

So generally the processors are made on thin silicon(pure),and this processors contains billions of transistors for performing tasks. Imagine a scale 15cm , genrally we think its smaller but each centimeter contains 10⁷ nanometers.

So this shows how smaller a nano-meter is ,Coming to the point when a company manfactures a cpu chip in the intermediate process it uses a process called lithography process.

In this process the processor is designed on silicon ,transistors are arranged on the surface of silicon. The work of these transistors is to transfer signals and perform logic operations(like switch on or off). 7nm is actually the distance between one transistor to other .

Does this 7nm matters ? Yes , shorter the distance faster the processor. During the transfer of signals if the distance is shorter it is obvious that the signals can travel faster and consumes less power and also generates less heat , which is an advantage to the processor. Apple’s A11 bionic processor is a 10nm process, also A13 chip contains 8.5 billion transistors while A11 contains only 4.3 billion transisters. Also Intel highest processor i9–10980XE has managed to design using 14nm process. In the present world where there is need for speed, fast processors this 7nm is a gifted process to make them more advantage over other companies/processors.

When it comes to Qualcomm Snapdragon 865(Second highest processor after A13 bionic ) also a 7nm process.

During the comparision of processors this process also plays an important role. Companies and Tech gaints like Intel, TSMC, and Samsung these three companies are currently planning or developing a 5-nanometer node, by the end of 2021/2022, ”Future is Amazing and interesting ”.
