Brightness
The maximum brightness in nits provided by the smartphone display.
The brighter the display, the more readable the picture remains on it under intense ambient light (for example, outdoors on a clear sunny day). Also, high brightness is important for the correct displaying of HDR content. However, a large amount of brightness affects the cost and power consumption of the screen. Manufacturers can specify standard, maximum, and peak brightness values. At the same time, an equal sign cannot be put between the maximum and peak brightness. The first indicates the ability of the screen to produce the specified brightness over its entire area, while the peak one — in a limited area and for a short time (mainly for HDR content).

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.CPU frequency
The clock frequency of the CPU that the device is equipped with. For multi-core processors, which are standard in modern smartphones, the frequency of each individual core is implied; and if the processor has cores with different frequencies (see "Number of cores") — usually, the maximum indicator is given.
In general,
high performance smartphones have high frequency of the processor. However, note that this parameter itself is not directly related to the capabilities of the CPU: many other features of the chip affect the actual performance, and often a low cost solution with a higher clock speed turns out to be less performant than an expensive one, and at the same time, presumably, more "slow" processor. In addition, the overall performance of the system directly depends on a whole set of other factors — primarily the amount of RAM. Therefore, when evaluating a smartphone, it is worth focus not so much on the frequency of the processor, but on the general specs of the system and visual indicators like the results in tests (see below).
CPU cores
The number of cores in the processor of a mobile phone.
The core in this specific case refers to the part of the processor that executes one thread of commands. Accordingly, the presence of multiple cores allows you to work with multiple threads simultaneously, which has a positive effect on performance. At the same time multi-core CPUs are now found even in the most inexpensive modern smartphones — even
chips with 8 cores are not uncommon among them, not to mention simpler
quad -core and
six-core solutions. And some modern processors can have up to
10 cores.
Theoretically, more cores can improve processor efficiency. However, in fact, the performance of the CPU (and the smartphone itself, eventually) depends on many additional factors. Thus the number of cores is purely a reference parameter. For example, a high-end quad-core processor may be much more performant than an inexpensive eight-core one. So you really should focus on overall level of performance and the results shown in various tests (see below)
It is also worth mentioning that individual cores of mobile CPUs may vary in clock speed, performance and power consumption. The classic version is 8 cores working according to the “4 + 4” scheme: 4 relatively “weak” and power efficient cores are responsible for simple tasks like Internet surfing, and ano
...ther 4 – more powerful ones - turn on when high performance is required (for example, in games with advanced graphics). This scheme of work allows you to achieve the optimal balance between performance and energy efficiency of CPU.GPU
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.
Memory storage
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.Test results
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.
AnTuTu Benchmark
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 900K 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.
Geekbench
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.
