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 a device when undergoing a performance test (benchmark) in the AnTuTu Benchmark.

AnTuTu Benchmark is a comprehensive test designed specifically for mobile devices, primarily smartphones and tablets. It evaluates the performance of the processor, memory, graphics, and input/output systems, providing a clear impression of the system's capabilities. The better the performance, the higher the score. According to AnTuTu, top models are those that score more than 500,000 points.

As with any benchmark, this test does not provide absolute precision; for more details on measurement inaccuracies, see the "3DMark Gamer's Benchmark" section.

Geekbench

The result shown by the device when passing the performance test (benchmark) Geekbench.

Geekbench is a specialized benchmark designed for CPUs. Since version 4.0, the test has also been applied to graphics accelerators; towards the end of 2019, the benchmark was released under the number "5". The characteristics of portable gadgets usually provide data specifically for the CPU. During testing, Geekbench simulates the workloads that occur when performing real-world tasks, and takes into account both the capabilities of a single core and the efficiency of multiple cores running simultaneously. Thanks to this, the final results characterize well the capabilities of the processor in everyday use. In addition, the test is cross-platform and allows you to compare the CPUs of different devices (smartphones, tablets, laptops, PCs). The help information only lists the multi-core test values for CPU.

Bluetooth

Bluetooth version supported by the tablet.

Bluetooth itself is a technology for direct wireless communication between various electronic devices. It can be used for various purposes, in particular, exchanging files with another Bluetooth device (laptop, mobile phone), connecting wireless headphones and headsets, peripheral devices (keyboards, mice), etc. The Bluetooth connection does not require both devices to be in line of sight and is stable as they move within range. The range and additional features depend on the connection version:
  • 2.0. The earliest of the Bluetooth variations used in today's tablets. Provides a data transfer rate of about 2.1 Mbps.
  • 2.1. This version differs from 2.0 in a number of improvements: enhanced security, reduced power consumption and compatibility with NFC technology.
  • 3.0. This version is a combination of a Bluetooth 2.1 module and a high-speed add-on that allows you to transfer data at speeds up to 24 Mbps. Thanks to this, the connection is able to automatically adapt to the situation: for small amounts of data, a slow channel is used that does not consume much energy, and for large volumes, the high-speed part is used.
  • 4.0. June 2010 version. It is notable for the fact that it combines three protocols: classic, high-speed and BLE (low power consumption). The latter is the most economical at the time of release - the power consumption is so low that the CR2032 "tablet" batteries la...st for several years of operation. The data transfer rate via the BLE protocol is up to 1 Mbps. According to the classical and high-speed protocol, Bluetooth 4.0 is almost the same as version 3.0 (see above).
  • 4.1. Development of the version 4.0 described above. One of the key improvements was the optimization of collaboration with LTE cellular modules in order to avoid mutual interference. In addition, it became possible to operate Bluetooth devices simultaneously in several roles (for example, to broadcast audio to a headset and remotely control another device).
  • 4.2. The next, after 4.1, is a key update to the Bluetooth standard. Introduced a number of key innovations for working in the "Internet of Things" (Internet of Things), as well as general improvements in speed and noise immunity.
  • 5.0. Bluetooth version 5.0, introduced in 2016. In general, it continued the trend set by the 4.2 standard, has even more extensive opportunities for working with the Internet of Things. In particular, in the Bluetooth Low Energy protocol (see "4.0" above), it became possible to double the data transfer rate (up to 2 Mbps) at the cost of reducing the range, as well as quadruple the range at the cost of reducing the speed; in addition, a number of improvements have been introduced regarding simultaneous operation with a large number of connected devices.
  • Bluetooth v 5.1. Update of the version described above v 5.0. In addition to general improvements in the quality and reliability of communication, this update has implemented such an interesting feature as determining the direction from which the Bluetooth signal is coming. Thanks to this, it becomes possible to determine the location of connected devices with an accuracy of a centimeter, which can be useful when searching for various accessories - for example, Bluetooth headphones or a wireless gamepad.
  • Bluetooth v 5.2. The next, after 5.1, is the Bluetooth 5th generation update. The main innovations in this version are a number of security improvements, additional power optimization in LE mode, and a new audio signal format for synchronized parallel playback on multiple devices.
  • Bluetooth v 5.3. The Bluetooth v 5.3 wireless protocol was introduced at the dawn of 2022. Among the innovations, it accelerated the process of negotiating the communication channel between the controller and the device, implemented the function of quickly switching between the state of operation in a small duty cycle and high-speed mode, improved the throughput and stability of the connection by reducing the susceptibility to interference. In case of unexpected interference in the Low Energy mode of operation, the procedure for selecting a communication channel for switching is now accelerated. There are no fundamental innovations in protocol 5.3, but a number of qualitative improvements are seen in it.

Digital compass

A sensor that allows you to determine the direction to the cardinal points. Uses the earth's magnetic field, like a conventional mechanical compass, so the accuracy of the readings can be quite low. However, tablets are rarely used for high-precision compass navigation, and this disadvantage is not critical.

Main

— The number of lenses. The characteristics of the main (rear) camera of the tablet are represented primarily by the number of modules, which in most cases are 1, but there are also tablets with a dual camera.

— Resolution. The second important factor of the camera is the number of megapixels. Many really believe that the more MP, the better the 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. Rear cameras in tablets may well be used for photo and video shooting; therefore, they have cameras of 8 MP, 10 MP and even higher (12 and 13 MP).

— Autofocus. For focus in such cameras, a movable lens system controlled by automation is responsible. It takes some time for the automation to work, and the lenses themselves turn out to be more complicated and more expensive than optics with a fixed focus (fixed lenses that are initially set to a large range of distances). However, the quality of the pictures is disproportionate...ly higher than that of cameras without autofocus, and the systems themselves are constantly being improved, and their response time is increasingly approaching instantaneous.

Flash. Flash significantly expands the capabilities of the camera. First of all, it allows you to shoot in low light conditions; in this case, the backlight, usually, can also be used in the constant glow mode — for video shooting. The second situation where a flash can come in handy is backlighting when the subject is in shadow. In addition, in many tablets, the flash LED can also be used as a regular flashlight, without a camera.

More features

- FM receiver. A feature that allows you to listen to FM radio on your tablet. It should be borne in mind that for reliable reception, you may need to connect wired headphones (usually via a 3.5 mm mini-Jack connector) - their cable in this case will play the role of an antenna.

- Fingerprint scanner. Fingerprint sensor. Used to recognize the user in appropriate situations: when unlocking the tablet, when authorizing in different accounts, when confirming payments, etc. It can be located in different places on the tablet - in front, behind, on the side, on the screen. This authentication method is much more convenient and safer than passwords: they can be forgotten or accidentally opened to strangers, while the finger is not lost, and it is very difficult to fake a fingerprint.

- 3D face scanner. A special technology for recognizing the user's face - not just by photographing, but by building a three-dimensional model of the face based on data from a special module on the front panel. This technology is constantly being improved, in our time it is able to take into account the change in hairstyles and facial hair, the presence of glasses, makeup, etc. At the same time, the recognition of twins and children's faces still remains weak points (they have fewer individual features than adults ). The main use of a face scanner is...authentication when unlocking a tablet, entering applications, making payments, etc. At the same time, other, more original use cases are possible. For example, in some applications, the face scanner reads the user's facial expressions, and then this facial expression is repeated by a smiley on the screen.

- Gyroscope. A device that tracks the rotation of the tablet in space. Modern gyroscopes work on all three axes and are able to determine both the speed and the angle of deviation. This expands the control of the tablet, allowing you to give commands by tilting the device in one direction or another; This feature is especially popular in games.

Fast charging

By itself, fast charging, as the name suggests, reduces the charging time compared to the standard procedure. For this, increased voltage and/or current strength is used, as well as a special "smart" process control. But the possibilities and features of such charging may be different, depending on the specific technology used in the device. The same technology must be supported by the charger — this is the only way to 100% guarantee correct operation. However some types of fast charging are mutually compatible — however, this point should be clarified separately, and compatibility is not always complete.

Here is a brief description of the most popular technologies nowadays:

— Quick Charge (1.0, 2.0, 3.0, 4.0, 5.0). Technology created by Qualcomm and used in gadgets with Qualcomm processors. The later the version, the more perfect the technology: for example, Quick Charge 2.0 had 3 fixed voltage options, and version 3.0 introduced smooth adjustment in the range from 3.6 to 20 V. Most often, gadgets with a newer version of Quick Charge are also compatible with older chargers, but for full use it is desirable to match the versions.
Also note that certain versions of Quick Charge have become the basis for some other technologies, such as Asus BoostMaster and Meizu mCharge. However, again, the mutual compatibility of devices supporting these technologies needs to be clarified separately.

— Pump Express. Ow...n development of MediaTek, used in gadgets with processors of this brand. Also available in several versions, with improvements and additions as it develops.

— Samsung Charge (Samsung Fast Charge, Adaptive Fast Charging). Samsung's proprietary fast charging technology. It has been used without any changes since 2015, in light of which it looks rather modest against the background of newer standards. Nevertheless, it is able to provide good speed, especially in the first 50% of the charge.

— Huawei PowerUp. One of Huawei's proprietary technologies. Formally similar to Quick Charge 2.0, but used with both Qualcomm and other brands of mobile processors, so compatibility is not guaranteed. In general, it is considered obsolete, gradually being replaced by more advanced standards like the SuperCharge Protocol.

— Huawei FastCharge Protocol. Relatively simple fast charging technology used in gadgets from Huawei. In fact, it is an analogue of Huawei Power Up, fundamentally different only in name.

— Huawei SuperCharge Protocol. Another proprietary technology from Huawei introduced in 2016; for 2021 is available in several versions. In some devices, the power of such charging exceeds 60 V — not a record, but a very solid indicator.

Charger power

The power at which the tablet is charged in normal mode.

On the practical side, the higher the charging power, the less time spent on it (with the same battery capacity). But this parameter does not directly affect compatibility with chargers: modern devices are able to work with “chargers” of both higher and lower power. At the same time, in the first case, the battery controller will automatically limit the charging current, and in the second, charging will simply take more time. Accordingly, the standard charger may be of less power. And when looking for a third-party charger, you should focus on the allowable charging power indicated in the specifications — this will give the maximum guarantee against malfunctions.
