Brightness
The maximum brightness in nits provided by the tablet screen.
The brighter the display, the more readable the picture remains on it under intense ambient light. Also, high brightness is important for the correct display of HDR content. However, a large margin for this indicator 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).
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.
CPU speed
The clock speed of the processor installed in the tablet is actually the maximum number of operations performed by one processor core per second. This indicator is important for the speed of the system, but a high clock frequency in itself does not guarantee speed. The actual speed of the processor also depends on its architecture, the number of cores and many other features, and the overall speed of the device also depends on the amount of “RAM”, the installed OS, etc. Therefore, situations are not uncommon when
powerful advanced tablets have a lower CPU frequency than more modest models.
CPU cores
The number of individual cores provided by the tablet processor.
The core is the part of the processor that executes a single instruction stream. Accordingly, the more cores, the more threads the processor can simultaneously process and the higher its performance (ceteris paribus). On the other hand, numerous cores is not always an indicator of a high class processor and tablet as a whole. First, the actual performance of the chip depends on many other factors, and advanced dual-core processors often outperform inexpensive quad-core processors. Secondly, the development and cheapening of technologies has led to the fact that simple
quad-core CPUs have become quite affordable even for low-cost devices. And even
eight-core processors, which at one time were an unequivocal sign of advanced models, are increasingly found in relatively inexpensive tablets; the same can be said about relatively recent
processors with 10 cores. However it is worth noting that in such chips, the cores can be divided into main (with high performance) and additional (used in tasks that do not require power). For example, 8 cores can be divided into 4 main and 4 additional cores. However, such a division is often not a disadvantage, but an advantage: numerous full-fledged cores is rarely required in fact, and reduced power saves energy and improves battery life.
Graphics card
Model of the graphics card installed in the tablet. The graphics card in such devices is not a separate device, but part of the processor; however, she still has a clear specialization and is responsible for graphics.
Accordingly, the graphics capabilities of the tablet directly depend on the characteristics of the video accelerator. Theoretically, knowing the name, you can find detailed specifications of a graphics card, reviews, test results and other information and evaluate how it suits you. At the same time, in most cases there is no need to delve into such details — all system components, including the graphics card, are usually selected in such a way as to correspond to the general class of the tablet and the capabilities necessary for this class.
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.
Storage capacity
The volume of the tablet's own built-in storage. The larger it is, the more information (programs, games, movies, photos, etc.) can be stored on the tablet without resorting to removable media, rewriting to other devices, etc. At the same time, the amount of built-in memory significantly affects the cost. Therefore, some models are available in several versions, differing only in the capacity of the drive. And the variety of built-in memory is quite wide: from
16 GB to
1024 GB with a 2-fold increase (
32 GB,
64 GB,
128 GB,
256 GB,
512 GB).
Note that this paragraph indicates the total amount of internal memory. The operating system and default programs also take up space in it; therefore, the volume of the drive actually available to the user will inevitably be less than the total.
Many tablets allow you to add memory cards to the built-in drive (see below). Such cards are relatively inexpensive, but they are much slower, and the ability to work with them may be limited by the manufacturer — for example, not all tablets with this function allow installing applications on removable media.
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.
3DMark Gamer's Benchmark
The result shown by the device when passing the performance test (benchmark) 3DMark Gamer's Benchmark.
3DMark is a series of benchmarks originally designed to test the graphics performance of a device; later, these tests were supplemented by checking the capabilities of the processor. Testing is carried out primarily in terms of performance in games (in fact, the benchmark itself is described as “a game without the ability to influence the process”), however, given that modern games can have very high requirements, 3DMark is a fairly visual tool for assessing the overall performance of the system . And since the latest versions of the test are made cross-platform, it also makes it possible to compare devices under different operating systems and even different classes (for example, smartphones with tablets). The more points this or that model received on this test, the more performant it is.
It is worth noting that the results of any benchmark are usually quite approximate, because. they depend on many factors that are not directly related to the system — from the load of the device with third-party programs and ending with the air temperature during testing. The error due to these factors is usually on the order of 5-7 %; therefore, it is possible to speak of a significant difference between the two models only if the difference in their indicators goes beyond this error.
