Now all the crazy running around and screaming about that the new CPU will work on 7-nanometer process technology and the other on 5-nm, as Samsung actually working on a 3-nm. That’s all well and manufacturers like to show potential buyers all in a very simple figures. If they are better than last time, that’s all well and good gadget. If the same, then “ugh, nothing has changed.” Often it is not so, and we fall into the trap of unnecessary numbers imposed on us manufacturers. We have talked about cameras, let’s talk about processors and know whether we even understand what such a fabrication process, or let the engineers do it.

Where to use processors
We are surrounded by gadgets! They are everywhere and no longer just surrounded us and literally was taken hostage – we without them can not. Each has a processor. Sometimes everything is limited only to them and other chips are already made with him “in one bottle”. Sometimes separate elements such as the graphics card or something like that, but any computing element consists of a huge number of transistors.
When comes a new smartphone, computer, laptop or something in this spirit, the manufacturer specifies a mysterious nanometers, the number of which is decreasing every year and it is a good sign, and a sign of adaptability. This is probably the only figure, the reduction of which is good.
These nanometers are called process or in short the process. What is it?
What is the process
The vast majority of users never saw the CPU, except in pictures. Some were lucky enough to see them live, but not more than the heat distribution panel. For comparison, this is how to meet a girl, but to see it only in a ski suit. The most interesting is under this plate. That is, there arises a magic performance.
Under the plate is a crystal of the processor. It is not even billions of tiny, microscopic transistors, the distance between them is determined by the process technology.
Most modern processors (out of those enrolled in industrial production) now have a 7 nm (7-nm) process technology. Such technologies are now quite well mastered the Taiwanese company TSMC, which manufactures chipsets for ordering the world’s largest manufacturers, such as Apple, Huawei and Qualcomm. The last and even provides the lion’s share of processors for completely different manufacturers of Android smartphones.
Thus, it should be noted that a larger value of the process does not mean that the chip will have less transistors. It is his example proved Intel, which is not very good with technology to 7 nanometers.
Does the process when selecting the phone
Every year the process becomes less and less. Now it is 7 nanometers, in the coming months we will see processors with 5 nanometers, but not far off and 4 nm. Samsung is rumored to be going to prepare at 3 nm.
The advantage of smaller values, for which chase producers, investing billions of dollars, quite obviously. The smaller the process, the more productive and efficient will be the processor. Due to the smaller distance between the transistors, the data is transferred faster between them, and the energy it takes less. These are the main advantages.
Even with the same architecture, but with reduced process we obtain performance improvements, increasing the number of cores, reducing the cost of production, the allocation of more space for memory and other components since the crystal as a whole becomes more compact. There are other more specific advantages, which we now do not dwell.
What is the process
At the dawn of the computer industry to talk about such values, as it is now, it was not necessary, and processors of that time had the process technology, measured in micrometers (aka microns). This is the value component of one-thousandth of a millimeter. Even now it is difficult to visualize, but then it was altogether fantastic.
Gradually the speed of the reduction process was increased from values around 10 µm in the seventies, the producers came to the values of 0.6 µm in 1994. In 1997, the account began to nanometers. This is one millionth of a millimeter. The first processors with such a process has no value in the region of 350 nm.
At the beginning of a null-value fell below 100 nm, which were a breakthrough and psychological level, but did not stop. So in 2006, AMD Phenom II, Athlon II and others have suggested it is 40-45 nm. Following a twofold increase in transistor density has occurred already in 2012.
In 2016, was 14-16 nm, and in 2017, Apple, Qualcomm and some other companies have overcome the barrier of 10 nm. That is, ten millionths of a millimeter. Just imagine this amount!
Is it worth to pay attention to the CPU when buying a phone
Now the manufacturing process of modern processors has reached level 7 nanometers. This is a good indicator and the next step is 5 nm, but dwelling on it is not worth it. Of the processor there are many other options, and such a small change of the process you hardly notice.
It is more important to look at other indicators of the phone, and those extra 2-3 nm at this stage will give you an advantage only if you believe that it really is. A smartphone is a complicated thing and it grabs other things that affect performance.
For example, utilization of third-party applications, memory speed, architecture, the demands of applications with which you work, and more. In its pure form processor is faster and more economical. Of course, if you compare a 40-nm and 5-nm process technology, the difference will be, but between the past few years. Between the models, released the same year, there is no such difference in performance.
