Comparison Meizu M5s 16 GB vs Meizu M5 16 GB / 2 GB

The ratio of the screen area to the total front panel area of the phone. Simply put, this spec describes how much of the front panel is occupied by the screen; the rest is the bezels.

This indicator is given exclusively for smartphones with touch screens — it is for them that it is most relevant. The larger the percentage of the body is occupied by the screen, the thinner are the bezels, the neater the smartphone looks and the more convenient it is to work with it with one hand. As for specific numbers, the average values are 80 – 85 %, the higher values allow us to talk about a thin bezel, and more than 90 % — about a “bezel less” design.

Separately, we note that this parameter has nothing to do with the aspect ratio of the screen. The aspect ratio describes only the display itself — its proportions, the ratio between the larger and smaller side of the rectangle.

The most popular nowadays are chips from Qualcomm and MediaTek, CPUs from Unisoc are slightly less common. Qualcomm has several processors of each series, namely Snapdragon 778G, Snapdragon 7 Gen 1, Snapdragon 7+ Gen 2, Snapdragon 7s Gen 2, Snapdragon 7 Gen 3, Snapdragon 7+ Gen 3, Snapdragon 865, Snapdragon 870, Snapdragon 888, Snapdragon 8 Gen 1, Snapdragon 8+ Gen 1, Snapdragon 8 Gen 2, Snapdragon 8 Gen 3, Snapdragon 8s Gen 3. And Mediatek has a low cost series MediaTek Helio P and a line of advanced chipsets MediaTek Dimensity (Dimensity 1000, Dimensity 7000, Dimensity 8000, Dimensity 9000).

Knowing the name of the CPU model installed in the smartphone, you can find detailed data on a particula...r CPU and evaluate its level and general capabilities. This is especially true in light of the fact that these capabilities depend not only on the number of cores and clock speed, but also on the specific nuances of the design.

The clock frequency of the CPU that the device is equipped with. For multi-core processors, which are standard in modern smartphones, the frequency of each individual core is implied; and if the processor has cores with different frequencies (see "Number of cores") — usually, the maximum indicator is given.

In general, high performance smartphones have high frequency of the processor. However, note that this parameter itself is not directly related to the capabilities of the CPU: many other features of the chip affect the actual performance, and often a low cost solution with a higher clock speed turns out to be less performant than an expensive one, and at the same time, presumably, more "slow" processor. In addition, the overall performance of the system directly depends on a whole set of other factors — primarily the amount of RAM. Therefore, when evaluating a smartphone, it is worth focus not so much on the frequency of the processor, but on the general specs of the system and visual indicators like the results in tests (see below).

The model of the GPU used in the mobile phone.

This module is responsible for all tasks related to graphics; accordingly, its specs directly affect the efficiency of processing a particular picture. This is especially noticeable in the example of modern 3D games. Therefore, the presence of a powerful video adapter is especially important for gaming smartphones. And knowing the model of the GPU, you can find detailed data about it and evaluate its capabilities.

The parameter determines the overall performance of the smartphone: the more RAM, the faster the device works and the better it copes with an abundance of tasks and / or resource-intensive applications (ceteris paribus). This is even more true in light of the fact that large amounts of "RAM" are usually combined with powerful advanced processors. However, only devices with identical operating systems can be directly compared with each other, and in the case of Android, with the same versions and editions of this OS (for more on all this, see "Operating system"). This is due to the fact that different operating systems and even different versions of the same OS can differ markedly in terms of RAM requirements. For example, iOS, thanks to good optimization for specific devices, is able to work efficiently with 3 GB of RAM. For modern versions of Android in the regular edition (not Go Edition), the mentioned 3 GB is actually the required minimum. Under such an OS, it is better to have at least 4 GB or 6 GB of RAM. In high-end devices with powerful electronic "stuffing" you can also find more impressive numbers - 8 GB or even 12 GB or more.

The largest volume of memory card with which the phone supports. For more information about the cards themselves, see "Memory Card Slot"; here we note that capacious cards often use advanced technologies that are not supported by all devices, and sometimes phones 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. However, it is worth focusing on official data, because, if officially supported volume is exceeded, normal operation of the card is not guaranteed.

The test results are specified either by a younger model in a line or a particular model, made for a better understanding performance of phone models if you compare phones against these parameters. For example, the 128 GB model has test results, and the 256 GB model has no information on the network, and in both models you will see the same value that will give an understanding of the overall performance of the device. But if the editorial office has information for each model individually, then each model will have its test results filled out, and the model with bigger RAM will have bigger values.

The result shown by a device when undergoing a performance test (benchmark) in AnTuTu Benchmark.

AnTuTu Benchmark is a comprehensive test designed specifically for mobile devices, primarily smartphones and tablets. It evaluates the efficiency of the processor, memory, graphics, and input/output systems, providing a clear impression of the system's capabilities. The higher the performance, the more points are awarded. Smartphones that score over 900K points are considered high-performance according to the AnTuTu ranking.

Like any benchmark, this test does not provide absolute precision: the same device can show different results, usually with deviations within 5-7%. These deviations depend on various factors unrelated to the system itself, such as the device's load from third-party programs and the ambient temperature during testing. Therefore, significant differences between two models can only be noted when the gap in their scores exceeds this margin of error.

Communication standards supported by the mobile phone. In the modern world, several standards related to different generations are actively used: GSM, 3G, 4G (LTE), 5G (including fast mobile internet), CDMA. They vary in both specs and prevalence in different countries:

— GSM. The earliest of the communication standards found in modern telephones. Belongs to the second generation (2G). Allows you to make voice calls with acceptable sound quality, as well as transfer data at speeds up to 474 Kbps (using EDGE technology). Nowadays, GSM is considered completely obsolete, it has been almost universally replaced by more advanced standards of the next generations (3G, 4G, etc.). However, 2G support is found in most modern devices — not so much because of practical necessity, but because of technical features. The fact is that almost all communication standards that are relevant nowadays are add-ons over GSM, and modules for working with these standards are almost guaranteed to be compatible with GSM as well.

— 3G. In a broad sense, the 3G category (third generation communications) includes several standards. However, in the east european mobile phone market, this term refers specifically to the connection of the UMTS format. This standard is a development of GSM, such networks are often deployed on the basis of ready-made networks of the 2nd generation and c...an also serve GSM phones without problems. Specifically, UMTS provides data transfer rates from 2 to 70 Mbps, depending on additional technologies implemented by a particular operator. This is already comparable to fixed Internet access; so, despite the spread of newer standards, 3G communication and phones for it are still quite popular — especially since such devices are compatible with 4G and 5G networks.

— 4G (LTE). Communication 4 generations based on the LTE standard; other 4G standards are not used in mobile phones. LTE is a further development of 3G (UMTS), deployed on the basis of the same technical base, but operates at higher speeds — up to 173 Mbps, which is comparable to a full-fledged broadband Internet connection. LTE networks are commercially operated in many countries of the world, but not in all; therefore, before buying a 4G-compatible phone, it's a good idea to check if it will be possible to use all its features in your area.

— 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 speed (at high network load) of 100 and 50 Mb/s, respectively, as well as a number of solutions aimed at improving reliability and overall connection 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 mentioning the 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.

— CDMA. CDMA networks are known to users primarily by the activities of cell phone networks that provide the opportunity to receive a mobile phone with a direct city number. At one time, these networks competed with GSM and more advanced standards based on it, but as mobile communications developed and became cheaper, CDMA operators for the most part curtailed their activities in the voice communications market and switched to mobile Internet access services. It is worth noting here that the EV-DO Rev.A and Rev.B data transmission technologies available in CDMA networks are capable of providing connection speeds at the level of third-generation networks (up to 3.1 Mbps in the first case and up to 14.7 Mbps in the second), so in some places these services were promoted under the 3G label. However, this connection should not be confused with UMTS-based 3G (see above) — these are two fundamentally different standards that are incompatible with each other. Roughly speaking, if we are talking about 3G in a mobile phone, usually, we mean UMTS, but 3G modems more often use CDMA (EV-DO).

It is worth noting that the GSM, 3G and 4G standards (in that order) are, in fact, stages in the development of mobile networks of the same type. In fact, this means that a phone with support for a later standard, by definition, supports earlier ones — for example, a device with LTE is able to work with both GSM and 3G.

You also need to remember that different ranges can be used within the same standard, and not all of them can be supported in a mobile device. However phones officially sold in a certain country are usually optimized for local networks, and there should be no problems with them. But if the device is planned to be imported from another country, and it was not intended for the local market, it makes sense to first clarify the compatibility by bands. Otherwise, a situation may arise when the device simply “does not see” the network, although formally it will be compatible with a certain communication standard.
