Comparison Samsung Galaxy Tab S2 VE 9.7 2016 32GB 32 GB vs Samsung Galaxy Tab S2 9.7 2015 32 GB

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 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.

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.

- 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.

- Stereo sound. The ability to play full stereo sound through the tablet's own speakers. There must be at least two speakers for this task. This complicates the design and increases its cost, but it has a positive effect on the sound quality: the sound is more expressive and detailed than when using a single speaker, it has a volume effect, as well as a higher volume.

- 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.

- Face scanner (FaceID). A special technology for recognizing the user's face - not just by photographing, but by building a three-dimensiona...l 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.

— Dust-, water protection. The presence of the tablet case protection from dust, moisture and other similar adverse factors. The level of such protection may be different, but such devices, at least, are not afraid of rain; and the most resistant models allow even long-term work under water. Be that as it may, dust- and water-resistant tablets will be useful for those who are constantly in adverse conditions: tourists, rescuers, military, sailors, etc. However, it should be borne in mind that not every such device has shock protection (see below). ).

- Impact protection. The presence of the body of the tablet protection against bumps and falls. A characteristic feature of devices with this feature is a solid massive body, often with a bumper made of elastic material at the ends. The degree of impact resistance can be different, however, even the most limited models, as a rule, can withstand a fall from a height of about 1 m without problems; more detailed data should be sought in the manufacturer's documentation. Note that the presence of shock protection significantly affects the cost, and for domestic use, a protective cover is usually enough for a regular tablet. So paying attention to shock-resistant models is primarily for those who are constantly in conditions with an increased risk of "accidents": builders, rescuers, military, etc.

- MIL-STD-810 security standard. Initially, this is a set of specifications that establishes certain levels of protection for electrical equipment from environmental factors. The standard was developed with the aim of testing military equipment for the US Army to maintain performance in various adverse conditions. It imposes rather stringent requirements on the test subjects: the level of product resistance to impacts during falls and shakes is checked, vibration tests are carried out, the device is tested in a wide temperature range, in rain, in fog, under the influence of sand, dust, etc. However, the MIL-STD-810 label in "civilian" products does not always mean the highest degree of protection. This is due to the lack of strict regulation of the tests. So, the most ingenious vendors test the tested gadgets literally on one or two points of the programme from an extensive list and often deliberately do not cover which tests were passed. Accordingly, the specific features of such protection remain reliably unknown. The standard has been in force since 1962. Each new version of it is indicated by a letter of the Latin alphabet at the end. The further the letter down the alphabet, the more recent the version of the certificate. Since 2008, the MIL-STD-810G specification has been in effect everywhere, and in 2019 a new edition of the MIL-STD-810H standard was approved.
