And Mediatek has a low cost series MediaTek Helio P and a line of advanced chipsets MediaTek Dimensity (Dimensity 1000, Dimensity 7000, Dimensity 8000, Dimensity 9000).

Knowing the name of the CPU model installed in the smartphone, you can find detailed data on a particula...r CPU and evaluate its level and general capabilities. This is especially true in light of the fact that these capabilities depend not only on the number of cores and clock speed, but also on the specific nuances of the design.

End-to-end processor rating (regardless of chipset manufacturer) for Android smartphones. It is based on a set of maximum performance indicators of the processor itself, the memory bus, the graphics core, etc. Processor ratings can be useful to enable comparison and easy selection of similar models.

The model of the GPU used in the mobile phone.

This module is responsible for all tasks related to graphics; accordingly, its specs directly affect the efficiency of processing a particular picture. This is especially noticeable in the example of modern 3D games. Therefore, the presence of a powerful video adapter is especially important for gaming smartphones. And knowing the model of the GPU, you can find detailed data about it and evaluate its capabilities.

The volume of storage installed in the phone.

This volume directly determines how much data can be stored on the phone without using removable memory cards. This indicator is especially important for models that don't have memory card slots. However, even if memory cards are supported, built-in storage is still preferable: at least it works faster, and it usually has fewer restrictions on its use (in particular, most smartphones allow you to install applications only on storage).

As for specific volumes, the actual minimum for a modern smartphone is 32 GB; less “capacious” devices are becoming increasingly rare these days. 64 GB is considered a comfortable minimum, 128 GB is considered average indicator, 256 GB - above average. Some high-end devices are equipped with 512 GB and even 1 TB< /a>.

We also note that the actual amount of memory available to the user will inevitably be somewhat less than the total, since part of the drive is occupied by operating system files.

The type of the phone's storage.

The specification determines, first of all, the speed of the memory, and, accordingly, the performance of the device as a whole (especially when working with large amounts of data or resource-intensive applications). Nowadays, there are two basic specifications — eMMC and UFS; each of them has several versions. In general, storages with UFS 3.1 and UFS 4.0 are the fastest and most advanced today, but they cost accordingly, and therefore are used mainly in premium smartphones. A more detailed description of these standards looks like this:

— eMMC. One of the simplest and most affordable standards for solid state memory — for example, this specification is used by most flash drives. In smartphones and other portable gadgets, this standard was generally accepted until 2016, when the introduction of UFS began; however, even now it is very popular — mainly due to its low cost and low power consumption. But the speeds of eMMC are noticeably lower than those of UFS. So, in the latest version of eMMC 5.1A (2019), the read speed is up to 400 MB/s, and the earlier and more common version of eMMC 5.1 provides up to 250 MB/s in read mode, up to 125 MB/s in sequential write mode and all only up to 7.16 MB/s with random writes (in other words, in application mode).

— UFS. A solid state drive standard designed to be a faster, more advanced successor to eMM...C. In addition to the increased data exchange speeds, the format of work has also been changed in UFS — it is fully duplex, that is, reading and writing can be performed simultaneously (whereas in eMMC these processes were performed in turn). Also, efficiency in random read and write mode has been significantly improved, which has a positive effect on the quality of work with applications. Specific data exchange rates and features of work depend on the version of UFS, nowadays you can find the following options:

• 2.0. The earliest of the versions found in modern smartphones; was released back in 2013. Provides data transfer rates up to 1.2 GB/s, the maximum available in this version. The newer version 2.1 has the same speeds, but it is supplemented with a number of important innovations. Therefore, UFS 2.0 memory is rarely used in mobile phones.
• 2.1. The first of the versions that are widely used in smartphones; was released in 2016. In terms of speed, it does not differ from version 2.0 described above, and the main differences are in some improvements. In particular, UFS 2.1 introduced storage status indicator (“health”), the ability to remotely update the firmware, as well as a number of solutions aimed at improving overall reliability.
• 2.2. An evolution of the UFS 2.x standard introduced in Summer 2020. A key improvement is the introduction of the WriteBooster feature (originally introduced in UFS 3.1); this feature allows you to significantly increase the write speed and, accordingly, the overall performance in tasks like running applications.
• 3.0. A version released in 2018 and implemented in hardware a year later. The throughput was increased to 2.9 GB/s per two lines (1.45 GB/s per one), new versions of the M-PHY electronic protocol (physical layer) and UniPro based on it were introduced, the reliability of working with data and the temperature mode of operation of the controllers has been expanded (theoretically, it can range from -40 °С to 105 °С). UFS 3.0 is used mainly in fairly advanced smartphones, although in the future we can expect this specification to be extended to more modest models.
• 3.1. The successor to the UFS 3.0 standard, officially introduced in early 2020. It is positioned as a specification created specifically for high-performance mobile devices and aimed at increasing speed while minimizing power consumption. To do this, UFS 3.1 has a number of innovations: a non-volatile Write Booster cache to speed up writing; special DeepSleep power saving mode for relatively simple and inexpensive systems; as well as the Performance Throttling Notification feature, which allows the drive to send overheating signals to the control system. In addition, this standard may additionally provide support for the HPB extension, which improves reading speed.
• 4.0. UFS 4.0 doubled the throughput per lane (23.2 Gbps per lane) and improved energy efficiency by about 46% (compared to the previous 3.1 specification). UFS 4.0 standard memory modules provide maximum read speed up to 4200 MB/s, write speed up to 2800 MB/s. The high bandwidth makes the memory standard ideal for 5G smartphones.

The test results are specified either by a younger model in a line or a particular model, made for a better understanding performance of phone models if you compare phones against these parameters. For example, the 128 GB model has test results, and the 256 GB model has no information on the network, and in both models you will see the same value that will give an understanding of the overall performance of the device. But if the editorial office has information for each model individually, then each model will have its test results filled out, and the model with bigger RAM will have bigger values.

The result shown by a device when undergoing a performance test (benchmark) in AnTuTu Benchmark.

AnTuTu Benchmark is a comprehensive test designed specifically for mobile devices, primarily smartphones and tablets. It evaluates the efficiency of the processor, memory, graphics, and input/output systems, providing a clear impression of the system's capabilities. The higher the performance, the more points are awarded. Smartphones that score over 1.1M points are considered high-performance according to the AnTuTu ranking.

Like any benchmark, this test does not provide absolute precision: the same device can show different results, usually with deviations within 5-7%. These deviations depend on various factors unrelated to the system itself, such as the device's load from third-party programs and the ambient temperature during testing. Therefore, significant differences between two models can only be noted when the gap in their scores exceeds this margin of error.

The result shown by a device when undergoing a performance test (benchmark) in Geekbench.

Geekbench is a specialized benchmark designed for processors. Since version 4.0, it also includes tests for graphics processors, and by the end of 2019, version 5 of the benchmark was released. Typically, the specifications for portable gadgets include data specifically for the CPU. During testing, Geekbench simulates workloads that occur during real-world tasks, evaluating both single-core performance and the efficiency of multi-core operations. This provides a solid overview of the processor's capabilities in everyday use. Additionally, Geekbench is cross-platform, allowing for comparisons between the CPUs of different devices (smartphones, tablets, laptops, PCs). In reference materials, only the multi-core test results for the processor are usually provided.

Specifications of the main lens of the rear camera installed in the phone. In models with several lenses (see “Number of lenses”), the main one is responsible for basic shooting capabilities and does not have a pronounced specialization (wide-angle, telephoto, etc.). Four main parameters can be indicated here: resolution, aperture ( high aperture optics are quite common), focal length, additional sensor data.

Resolution(in megapixels, MP)
Resolution of the sensor used for the main lens. Budget options are equipped with a module 8 MP and below, many models have 12 MP camera / 13 MP, also recently a trend towards increasing megapixels has been popular. Often in smartphones you can find the main photomodule at 48 MP, 50 MP< /a>, 64 MP and even 108 MP .

The maximum resolution of the resulting image directly depends on the resolution of the sensor; and the high resolution of the "picture", in turn, allows you to better display fine details. On the other hand, an increase in the number of megapixels in itself can lead to a deterioration in the overall image quality - due to the smaller size of each individual pixel, the noise level increases. As a result,...the direct resolution of the camera has little effect on the quality of the shooting - more depends on the physical size of the matrix, the features of the optics and various design tricks used by the manufacturer.

Aperture
Aperture describes the ability of a lens to transmit light. It is written as a fractional number, for example f/1.9. Moreover, the larger the number in the denominator, the lower the aperture ratio, the less light passes through the optics, all other things being equal. For example, an f/2.6 lens will be “darker” than f/1.9.

High aperture gives the camera a number of advantages. First, it improves the quality of shooting in low light. Secondly, it's possible to shoot at low shutter speeds, minimizing the effect of "stirring" and blurring of moving objects in the frame. Thirdly, with fast optics it is easier to achieve a beautiful background blur ("bokeh") — for example, when shooting portraits.

Focal length(in millimetres)
The focal length is a distance between the sensor and the centre of the lens (focused to infinity), at which the most clear image is obtained on the matrix. However, for smartphones, the specifications indicate not the actual, but the so-called equivalent focal length — a conditional indicator recalculated using special formulas. This indicator can be used to evaluate and compare cameras with different sensor sizes (the actual focal length cannot be used for this, since with a different sensor size the same real focal length will correspond to different viewing angles). (It is also worth saying that the equivalent focal length can be noticeably larger than the thickness of the case — there is nothing unusual in this, since this is a conditional, and not a real indicator).

Anyway, the field of view and the degree of magnification directly depend on the equivalent focal length: a larger focal length gives a smaller field of view and a larger size of individual objects that fall into the frame, and a decrease in this distance, in turn, allows you to cover more space. In most modern smartphones, the focal length of the main camera ranges from 13 to 35 mm; if compared with the optics of traditional cameras, then lenses with equivalent focal length up to 25 mm can be attributed to wide-angle lenses, more than 25 mm — to universal models “with a bias towards wide-angle shooting”. Such values are chosen due the fact that smartphones are often used for shooting in cramped conditions, when a fairly large space needs to fit into the frame at a small distance. Enlargement of the picture, if necessary, is most often carried out digitally — due to the reserve of megapixels on the sensor; but there are also models with optical zoom (see below) — for them, not one value is given, but the entire working range of the equivalent focal length (recall, optical zoom is carried out by changing the focal length).

Field of view(in degrees). It characterizes the size of the area covered by the lens, as well as the size of individual objects "seen" by the camera. The larger this field, the more of the scene gets into the frame, but the smaller the individual objects in the image are. The field of view is directly related to the focal length (see above): increasing this distance narrows the field of view of the lens, and vice versa.

Note that this parameter is generally considered important for professional use of the camera rather than for amateur photography. Therefore, viewing angle data is given mainly for smartphones equipped with advanced cameras — including in order to emphasize the high class of cameras. As for specific values, for the main lens they usually are in the range from 70° to 82° — this corresponds to the general specifics of such optics (universal shooting with an emphasis on general scenes and extensive coverage at short distances).

Additional Sensor Data
Additional information regarding the sensor installed in the main lens. This item can specify both the size (in inches) and the sensor model, and sometimes both parameters at once. Anyway, such data is provided only if the device is equipped with a high-end sensor. With the model, everything is quite simple: knowing the name of the sensor, you can find detailed data on it. The size is worth considering a little more.

The size of the sensor is traditionally indicated in fractional parts of an inch — accordingly, for example, a 1/2.3" sensor will be larger than 1/2.6". Larger sensors are considered more advanced, as they provide better image quality at the same resolution. The logic here is simple - due to the large sensor area, each individual pixel is also larger and gets more light, which improves sensitivity and reduces noise. Of course, the actual image quality will also depend on a number of other parameters, but in general, a larger sensor size usually means a more advanced camera. In advanced photo flagships, you can find matrices with a physical size of 1”, which is comparable to image sensors used in top compact cameras with fixed lenses.
