From battery life to quality photos, all on a smartphone controlled by the processor. Understand why you should thank this little chip
?The essential invisible to the eyes?. Although the phrase of the work 'The Little Prince', by French author Antoine de Saint-Exupry, is used in more romantic contexts, it also applies to smartphones: because everything you value on your phone, be it the high resolution screen, the cameras with multiple functions or the battery that makes you reach the end of the day, is due to a chip hidden inside the device.
Although it seems obvious, the processor the most important component of any smartphone, this is because he who dictates what technologies the device is able to withstand. In addition, also the processor that indicates how fast and efficient your smartphone will be in relation to competitors after all, a more sophisticated chip usually does what others already do, but it does better.
Without the processor, or without a sufficiently advanced processor, features that go beyond the simple execution operating system and applications would also not work. It would not be possible to store your data with security or have functions that are always active, such as Crab it's the Google Assistant. Nor would it be possible to browse the internet, since SoCs (Chip System, in English) incorporate up to modem your cell phone.
It influences the functions and price of your smartphone
Except for very specific chips, such as M7 coprocessor, responsible for computing the data of the movement sensors of the iPhone 5S, virtually all functions of your smartphone are centralized in the processor. The CPU, in fact, is not usually composed of a single chip, but of a set of them. from which comes the term ?System on a Chip"Or"SoC?, As we talked about above.
In a SoC like the Snapdragon 865, which is less than a 5 cent coin, it is possible to find the units responsible for the graphic processing (read everything you see on the screen), processing cores, what will I say if your smartphone quad, hexa or octa-core, O image processor, which manages the signal captured by the cameras and a lot more.
Year by year, processors increasingly incorporate more funes. By integrating a resource that previously required another component to function, energy is saved, in addition to gaining velocity, functioning.
When the 4G began to be implemented in smartphones, for example, it was common for the modem not to be incorporated into the processor. The fact that the network is operated on a part chip meant, among other limitations, greater energy expenditure. Today, with the implementation of 5G, history repeats itself: the Snapdragon 865 prepared for 5G, but does it with a auxiliary chip.
And the adoption of the auxiliary chip is not conditioned to the smartphone having 5G, because the whole network Snapdragon 865, including the 4G receiver, is on a modem that is outside the processor. This also means that more space will be consumed in the components, forcing smartphones with that chip to be larger or sacrifice the size of other parts, such as drums.
Furthermore, like all models equipped with the SD865 obligatorily 5G, this should also make them more expensive. Although this new network is far from reality in some countries, such as the Brazil.
The processor also anticipates future functions
We are not Qualcomm that makes processors for smartphones. Although it is the most remembered, it is important to emphasize that Samsung also makes the chips Exynos, which equip some models in Brazil, the Huawei uses its own line, Kirin, and the Apple she always claims that the fact that she produces her processors gives her an advantage over the competition.
In the case of Qualcomm, Samsung and Huawei, designing a single chip that will be used in several smartphones released throughout the year, sometimes from different brands, even means that the processor needs to support technologies that do not yet exist on the market, such as 200 megapixels and video recording 8K. While we?re unlikely to see anything with these capabilities in 2020, the Snapdragon 865 and the Exynos 990 I'm already prepared for them.
this same factor that explains the fact that some functions of different smartphones are equivalents: if all are equipped with same processor, it is very likely that everyone supports fast loading, game rendering and other technologies presented with this chip. What will make the difference are other components and how each manufacturer exploits them, only.
J for Apple, philosophy somewhat different: how the company has total control of its production, knowing intimately all the components that will equip the next ones iPhones and iPads, it is possible to improve only what is necessary. This results in a processor equipped for all the functions of the device and more energy efficiency.
Furthermore, the fact that software It will also be done by the same company that impacts how the processor is capable of handling the operating system. Such reason still allows Ma update your devices by more time.
How to choose the best processor for you
Unlike what occurs in computers, where we see the same notebook model with different memory and processing sets, smartphones are sold as one closed package. This means that if the manufacturer wants to be successful in sales, equip its devices with the best processor possible for a price range, however, there are exceptions.
In many cases, it is possible for a manufacturer to prioritize other items, such as the screen, cameras, or finish. This occurs mainly in input and intermediates, since the balance between the final price and the cost of the device is more difficult to achieve. In these situations, it is worth staying connected in the analyzes and comparisons and analyzes of launches that leave here in Showmetech; We always take the price and competitors of a device into account when evaluating its performance.
So, in addition to how many cores have a chip and what speeds it can reach, important to be aware of resources compared to previous SoCs, of the same category, of course, and to increments: be it in performance or in efficiency. One of the efficiency indicators to be lithograph, which can be understood as the scale in which the components of a processor are produced.
Basically, how much smaller lithography, more transistors can be inserted on a chip of the same size. Multiplying transistors, in addition to making the processor more powerful, allows it to operate at lower frequencies, which in turn is reflected in greater energy efficiency. A more modern architecture usually matters more than a larger number of cores or a higher operating frequency.
For example, have you noticed that years ago the mobile market has processors with approximately 2GHz maximum speed, but that are still surpassing each year? This is due to the industry's efforts to extract more performance with each time less energy consumption.
