CPU
The model name of the processor installed in the tablet.
The processor is the “heart” of the device. It is he who is responsible for performing all the computing operations necessary for the normal operation of the tablet, and largely determines the overall performance. Knowing the name of a specific processor model, you can easily find detailed information on it, incl. and comparison with other models.
The most popular chips these days are from
Qualcomm(in particular, the top solutions
Snapdragon 800 series and
Snapdragon 8 series),
MediaTek(budget and “mid-range”
MediaTek Helio processors and the line of advanced
MediaTek Dimensity chipsets with 5G support), and among Windows tablets
Intel processors (mainly the
Intel Core family) are often found. Quite a rarity are branded
Kirin processors from Huawei and Honor.
RAM
The amount of random access memory (RAM) installed in the tablet. This memory is used for direct data processing, and therefore its volume is one of the main indicators of system speed and power. However note that the optimal amount of RAM strongly depends on the OS used — different systems and even different versions of the same "OS" can vary greatly in terms of consumed resources. But models on the same OS can be compared with each other in terms of the amount of RAM.
As for specific values, indicators in
1 GB or less in our time are definitely a sign of a weak tablet.
2 GB and
3 GB can be called the entry level,
4 GB and
6 GB are middle class, and in the most advanced models,
8 GB, or even
16 GB can be installed (or even more) RAM.
AnTuTu Benchmark
The result shown by the device when passing the performance test (benchmark) AnTuTu Benchmark.
AnTuTu Benchmark is a comprehensive test designed specifically for mobile devices, primarily smartphones and tablets. When checking, it takes into account the efficiency of the processor, memory, graphics and I / O systems, thus providing a fairly visual impression of the capabilities of the system. The better the result, the more points are given at the end. Antutu's top models include
tablets that score over 500,000.
Like any benchmark, this option does not provide absolute accuracy; See 3DMark Gamer's Benchmark for more information on measurement uncertainties.
Full HD filming (1080p)
The resolution and maximum frame rate provided by the main camera when
recording Full HD (1080p) video at normal speed, without slow motion (if available).
The standard resolution for this format is 1920x1080. Note that this can be either the maximum shooting resolution or one of the relatively simple options in addition to more advanced standards (such as UltraHD 4K). At the same time, Full HD is considered more than a decent resolution by modern standards, and at the same time, it can be supported even by fairly simple and inexpensive tablets.
As for the frame rate, there are actually two values in normal shooting - Full HD 30 fps and
Full HD 60 fps. A higher frame rate allows you to achieve very smooth display of dynamic scenes - even fast-moving objects in the frame are seen as clearly as possible, with almost no blurring. However, the low shooting speed also has its advantages - it allows you to reduce the amount of material being shot. Therefore, tablets that support 60 fps may have the ability to reduce the frame rate to 30 fps. But speeds above 60 fps are already used for shooting slow-motion video (slow-mo); see "Slow-mo" for more on this.
Slow motion (slow-mo)
The frame rate supported by the device 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 fps). 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 device, 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. On the other hand, the higher the frame rate, the more performant the graphics part 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 characteristics of the tablet.
Ultra HD filming (4K)
The resolution and maximum frame rate provided by the main camera when
shooting UltraHD (4K) video at normal speed, without using slow motion (if available).
UHD 4K is the most advanced high-definition video standard in widespread use (more advanced standards exist but are not found on tablets).
The frame rate, in turn, determines how smooth the video will look, how clearly fast moving objects will be visible in it. With normal (not slow-motion) shooting in modern HD standards, including UHD, two options are actually used - 30 fps and
60 fps. The second option allows you to achieve very smooth video, with good motion detail in the frame and almost no blurring in dynamic scenes. However, it does affect the price.
Optical zoom
The presence of
optical zoom in the main camera (in modules for several lenses - at least in one lens, usually the main one).
Such an increase is carried out due to the movement of the lenses in the camera lens: shifting the lenses reduces the viewing angle, as a result, the objects remaining in the frame look larger. This is more effective than digital zoom, when a separate section of the image from the sensor is stretched over the entire frame: optical zoom, in contrast, allows you to use the entire area of \u200b\u200bthe sensor and shoot at full resolution, regardless of the zoom level. On the other hand, moving lens systems are quite complex and expensive, and it is difficult to achieve powerful optical zoom in tablets due to size limitations. And the optical zoom ratio is small - from a certain moment the camera switches to digital zoom or to a separate telephoto lens (there is also such a format of work).
Camera (front)
Resolution
of the front camera of the tablet.
There is an opinion that more megapixels means better quality of filming. However, this is not entirely true: only the maximum resolution of the resulting images depends on the resolution of the matrix, and their quality is determined by many other parameters. However a large sensor resolution may be a sign of an advanced camera, but this is not necessary — two "eyes" with the same number of megapixels can radically differ in the quality of shooting.
The main purpose of frontcameras in tablets is video communication, and for it high resolution is not critical. Therefore, the number of megapixels in such cameras is noticeably lower than in rear cameras — for example, 2 MP considered an acceptable value, 5 MP is not bad, 7 MP and 8 MP is good, 12MP — excellent.
Battery capacity
The capacity of the battery that is normally installed in the tablet.
Theoretically, a larger battery means longer battery life. However, in fact, the battery life of the tablet also depends on its power consumption — and it is influenced by the characteristics of the processor and screen, the installed OS, and other factors. Therefore, only models with similar characteristics can be compared in terms of battery capacity (and even such a comparison will be quite approximate); and to assess battery life, it is best to look at the directly claimed operating time in different modes.
