Comparison Realme 13 Pro Plus 512 GB / 12 GB vs Realme 13 Pro 512 GB / 12 GB

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.

The result was shown by the device when passing the Wild Life (Extreme) performance test (benchmark) from 3DMark.

The Wild Life (Extreme) benchmark offers two ways to test graphics performance: a quick test that evaluates instantaneous performance, and a longer test that subjects the device to sustained load. This way one can evaluate how stable performance remains and does not drop due to overheating or throttling. The benchmark is cross-platform, which makes it possible to compare devices running different OSs and even different classes (for example, smartphones and laptops).

It is important to understand that this test does not provide absolute accuracy. The same device can show different results — they depend on many factors not directly related to the system. The error caused by these factors is often on the order of 5–7%. So we can talk about a significant difference between the two models being compared if the difference in performance goes beyond the mentioned error.

The number of individual lenses provided in the module of the main (rear) camera of the device. Specified only if there are several lenses. At the same time, each «eye» has its own sensor and, in fact, is a separate camera; however, they can be used in conjunction, forming one image from data from several lenses, or mutually complementing each other's capabilities. As an illustration of the second case, the following example can be given: when using the zoom, the smartphone can automatically switch from the main optics to the telephoto lens when the magnification selected by the user exceeds a certain threshold.

The simplest version of the main module with several lenses is a dual camera, however, devices with 3 or more rear cameras are becoming more common (in some models, the number of lenses can reach six). Anyway, these cameras usually differ in specifications and perform different functions. So, an ordinary colour camera can be supplemented with a lens for black-and-white shooting, which improves contrast; in some models, lenses with different focal lengths allow you to choose the optimal viewing angle for certain conditions; information from an auxiliary lens (see below) is usually used to adjust the depth of focus on an already finished shot, etc. These details should be clarified separately, but anyway, several lenses mean more shooting options.

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.

Specs of the telephoto lens of the main camera installed in the phone.

These details are relevant only for cameras with several lenses (see "Number of lenses") — and not all, but only those where there is a lens with a large focal length (much larger than in the main lens) and, accordingly, relatively high magnification. In the same paragraph, four main parameters can be indicated: resolution, aperture ratio, focal length and additional sensor data.

Resolution(in megapixels, MP)
The resolution of the sensor used for the telephoto lens.

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 display small details better. 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 photos and videos — a lot also depends on the size of the sensor, the features of the optics and various design tricks used by the manufacturer.

As for the resolution of a telephoto lens, it is, usually, somewhat lower than that of the main optics (see "Main lens") or corresponds to it. It does not make sense to provide higher values for a number of reasons — in particular, beca...use a wide-angle main lens requires a fairly significant supply of pixels for digital zoom, and this is not so critical for a telephoto lens — its zoom level itself is quite high.

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, for example, an f/2.6 lens will transmit less light than f/1.9.

High aperture gives the camera a number of advantages: it allows you to shoot at low shutter speeds, minimizing the likelihood of “shake”, and also makes it easier to shoot in low light and shoot with artistic background blur (bokeh). However, for a telephoto lens, such features are not as important as for the main camera — such lenses usually have a specific purpose, and in this case a large depth of field is often more desirable, achieved just at a small aperture. So in general, this parameter is more of a reference than practically significant when choosing.

Focal length
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 sensor. 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).

Anyway, the viewing angle and the degree of magnification directly depend on the equivalent focal length: a larger focal length gives a smaller viewing angle 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. And since telephoto lenses must provide more magnification than the main optics, they, by definition, have a longer focal length. However compared to classic telephoto lenses for digital cameras, this distance is small — about 50 – 60 mm, or even less than 40 mm (which for a conventional camera corresponds to medium-focus and wide-angle optics, respectively). But this cannot be called a disadvantage, given the peculiarities of filming on smartphones. In addition, there are exceptions — smartphones with "long-range" optics of 80 mm or more, which is already quite a decent indicator for a traditional camera.

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 angle is, 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, the viewing angle data is given mainly for smartphones equipped with advanced cameras — including in order to emphasize the high class of cameras in this way. Specifically, in telephoto lenses, these angles are relatively small — we recall that high magnification in such optics is achieved precisely by narrowing the field of view. In most cases, the size of this field lies in the range of 45 – 52°.

Additional Sensor Data
Additional information regarding the sensor installed in the telephoto 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-class 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 1/3.4" sensor will be larger than 1/4". Larger sensors are considered more advanced, as they provide a better image at the same resolution. This is due to the fact that due to the larger sensor area, each individual pixel is also larger and receives 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. However, it should be said that sensors in telephoto lenses are generally noticeably smaller than in main lenses — for example, the mentioned 1/3.4" and 1/4" are quite common options. This is mainly due to the secondary role of such cameras — small sensors are cheaper. In addition, with long-range shooting, a large sensor, for a number of reasons, is not as important as in a regular one.

The frame rate supported by the phone in slow motion (slow-mo).

In general, such shooting is called "high-speed" because it is carried out at an increased frame rate (more than 60 frames per second). As a result, when playing at normal speed (60 fps and below), the video looks slow (hence the name “slow-mo”). Such slowing down can be used just for fun, and as an artistic tool, and even for scientific purposes — to capture movement that is too fast for human perception. Anyway, the higher the slow-mo frame rate, the more you can slow down the video and the more advanced the camera is in this regard; the minimum value nowadays is actually 120 fps, and in advanced devices this figure is 480 fps and even more(in some models — more than 7000 frames per second). On the other hand, the higher the frame rate, the more performant the GPU should be; and this, in turn, affects the price of the device, sometimes quite noticeably.

Also note that slow-mo shooting can only be available at certain resolutions, which are not always the maximum; these points can be directly specified in the specs of the smartphone.

The degree of magnification provided by the phone by changing the main cameras — switching from optics with the smallest focal length to a lens with the largest focal length.

For details on phones with multiple lenses, see "Number of Lenses" above. Here we specify what kind of approximation the most “long-range” main camera provides compared to the lens with the widest viewing angle. For example, if a smartphone has three main cameras — main, ultra wide-angle and telephoto — this paragraph will indicate the difference between the last two, thus it is possible to identify smartphones with a good zoom, which we think should be considered at the 4x magnification level. This means only the increase in the original, raw image, which occurs due to switching between lenses; software solutions (digital zoom) are not taken into account. And if one of the compared cameras has an optical zoom (see above), the original specs are taken for comparison, without using the zoom.

The actual magnification of the cameras may not correspond to the magnification indicated by the manufacturer, as these are different characteristics; see "Claimed Magnification" for details. Also note that this feature should not be confused with the already mentioned optical zoom: the latter is carried out by means of only one lens, without switching between cameras.
