Comparison UleFone Armor Pad 3 Pro 256 GB vs Blackview Active 8 Pro 256 GB

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).

This parameter shows how much of the tablet's front panel area is on the display. The higher the display/body ratio, the thinner the frames and the more compact the tablet (with the same diagonal), the more elegant and aesthetically pleasing it looks. This indicator is also important when holding the tablet with both hands at once (for example, in games): thin frames or even frameless models allow you to reach further with your fingers without removing your hands from the device.

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.

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.

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.

The largest amount of memory card with which the tablet is able to work correctly. For more information about the cards themselves, see "Memory Card Slot"; here we note that capacious media often use advanced technologies that are not supported by early models, and sometimes tablets simply do not have enough power to process large amounts of data. Therefore, for the convenience of choosing in our catalog, the maximum supported volume is indicated.

In fact, there are cases when some devices may exceed the claimed characteristics — for example, work with 8 GB of media with the claimed 4 GB of maximum capacity. However, it is worth focus on official data, because. if they are exceeded, normal operation with the card is not guaranteed.

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 700K 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.

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.
