Comparison Apple iPad 2018 32 GB vs Apple iPad Pro 9.7 2016 32 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).

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.

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.

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 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.

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.

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.

— 3G. Support for third-generation mobile networks (3G) by the modem. Usually it means work in UMTS networks (development of the GSM standard); Depending on the data transfer technologies supported by the network and the tablet itself, the maximum connection speed can vary from 2 to 70 Mbps. This is comparable to the speed of terrestrial Internet connection channels, so 3G connection can be comfortably used for web surfing, downloading files, watching streaming video, video calling, etc. In many models, classic voice calls to mobile and landline numbers are also available; most often these are devices with a small diagonal, which allows you to hold the tablet to your ear like a regular phone.

— 4G (LTE). Tablet support for 4th generation mobile communications — 4G(LTE). Such a connection provides data transfer speeds up to 173 Mbps according to the official specification (1 Gbps in the future), which gives even more comfort when surfing the Internet and other similar tasks than in 3G networks. In many LTE-tablets, classic voice calls to mobile and landline numbers are also available; most often these are devices with a small diagonal, which allows you to hold the tablet to your ear like a regular phone.

Note that the implementation of LTE in different countries and even regions is uneven, so before buying a tablet with such a module, it's ok to clarify the availability of coverage.
<...br> — 5G. Further, after 4G, the development of mobile communication standards. In the official specifications of this generation, a peak speed of 20 Gbps for reception and 10 Gbps for transmission, guaranteed reception and transmission speeds (at high network load) of 100 and 50 Mbps, respectively, as well as a number of solutions aimed at increasing reliability and overall communication quality. A set of such solutions includes, in particular, multi-element antenna arrays (Massive MIMO) and beamforming technologies (Beamforming) at base stations, as well as the possibility of direct communication between subscriber devices. With all this, this standard allows to reduce energy consumption in comparison with its predecessors.
Separately, it is worth touching on rumors about the dangers of 5G communications for health. According to modern scientific data, such a connection does not pose a danger to the human body, and the rumors mentioned are conspiracy theories that are not supported by any weighty arguments.
