Comparison Tecno Camon 20 Pro 256 GB / 8 GB vs Infinix Note 30 Pro 256 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 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 type of RAM installed in the smartphone.

All modern devices use LPDDR format RAM ( LPDDR4, LPDDR4x, LPDDR5, LPDDR5x, LPDDR5T). In addition to its miniature size, it differs from conventional computer RAM in supporting special data transfer formats (16- and 32-bit memory buses). But versions of such memory can be different:

- LPDDR3. The earliest current generation of LPDDR was introduced in 2012 and has been implemented in devices since 2013. Standardly operates at speeds up to 1600 MT/s (megatransactions per second) and frequencies up to 933 MHz; The “improved” version supports speeds up to 2133 MT/s. Nowadays, this standard is rarely found, mainly among outdated mobile devices.

- LPDDR4. The successor to LPDDR3, officially introduced in August 2014 (although the first hardware developments were released at the end of 2013). The operating speed, compared to its predecessor, has doubled - up to 3200 MT/s; frequency increased to 1600 MHz; and energy consumption was reduced by 40%. In addition, the data transfer format has changed - in particular, instead of one 32-bit bus, two 16-bit buses are used, and some security improvements have been introduced into the standard. This memory can be found in some medium-range smartphones. - LPDDR4x. An improved version of LPDDR4 wit...h reduced power consumption - the standard uses a voltage of 0.6 V instead of 1.1 V. In addition, some improvements were implemented in this type of RAM aimed at increasing speed (it reaches 4266 MT/s) and general optimization of operation - for example, a single-channel mode for undemanding applications. Thanks to such characteristics, this version of memory has become noticeably more widespread than the original LPDDR4. You can find it in mid- and high-end devices.

- LPDDR5. Further development of “mobile” RAM, officially announced at the beginning of 2019. The operating speed in this version is increased to 6400 MT/s, a differential signal format was introduced to improve resistance to interference and errors, and dynamic frequency and voltage control was introduced to reduce power consumption. The use of such memory modules is typical mainly for high-end smartphones.

- LPDDR5x. A more energy efficient and faster version of LPDDR5 RAM. The data transfer speed in it was increased to 8533 MT/s, and the peak throughput indicator was increased to 8.5 Gbit/s. The number of memory banks per channel in LPDDR5x is always 16. RAM of this standard is typical for advanced smartphones of the highest grade.

- LPDDR5T. T is for turbo. The operating speed of the LPDDR5T standard RAM has been increased to 9600 MT/s, and devices with such memory modules are about 13% faster compared to LPDDR5X. The memory operates in the low voltage range from 1.01 to 1.12 V. The corresponding modules are aimed at use in high-end mobile devices.

The type of the phone's storage.

The specification determines, first of all, the speed of the memory, and, accordingly, the performance of the device as a whole (especially when working with large amounts of data or resource-intensive applications). Nowadays, there are two basic specifications — eMMC and UFS; each of them has several versions. In general, storages with UFS 3.1 and UFS 4.0 are the fastest and most advanced today, but they cost accordingly, and therefore are used mainly in premium smartphones. A more detailed description of these standards looks like this:

— eMMC. One of the simplest and most affordable standards for solid state memory — for example, this specification is used by most flash drives. In smartphones and other portable gadgets, this standard was generally accepted until 2016, when the introduction of UFS began; however, even now it is very popular — mainly due to its low cost and low power consumption. But the speeds of eMMC are noticeably lower than those of UFS. So, in the latest version of eMMC 5.1A (2019), the read speed is up to 400 MB/s, and the earlier and more common version of eMMC 5.1 provides up to 250 MB/s in read mode, up to 125 MB/s in sequential write mode and all only up to 7.16 MB/s with random writes (in other words, in application mode).

— UFS. A solid state drive standard designed to be a faster, more advanced successor to eMM...C. In addition to the increased data exchange speeds, the format of work has also been changed in UFS — it is fully duplex, that is, reading and writing can be performed simultaneously (whereas in eMMC these processes were performed in turn). Also, efficiency in random read and write mode has been significantly improved, which has a positive effect on the quality of work with applications. Specific data exchange rates and features of work depend on the version of UFS, nowadays you can find the following options:

• 2.0. The earliest of the versions found in modern smartphones; was released back in 2013. Provides data transfer rates up to 1.2 GB/s, the maximum available in this version. The newer version 2.1 has the same speeds, but it is supplemented with a number of important innovations. Therefore, UFS 2.0 memory is rarely used in mobile phones.
• 2.1. The first of the versions that are widely used in smartphones; was released in 2016. In terms of speed, it does not differ from version 2.0 described above, and the main differences are in some improvements. In particular, UFS 2.1 introduced storage status indicator (“health”), the ability to remotely update the firmware, as well as a number of solutions aimed at improving overall reliability.
• 2.2. An evolution of the UFS 2.x standard introduced in Summer 2020. A key improvement is the introduction of the WriteBooster feature (originally introduced in UFS 3.1); this feature allows you to significantly increase the write speed and, accordingly, the overall performance in tasks like running applications.
• 3.0. A version released in 2018 and implemented in hardware a year later. The throughput was increased to 2.9 GB/s per two lines (1.45 GB/s per one), new versions of the M-PHY electronic protocol (physical layer) and UniPro based on it were introduced, the reliability of working with data and the temperature mode of operation of the controllers has been expanded (theoretically, it can range from -40 °С to 105 °С). UFS 3.0 is used mainly in fairly advanced smartphones, although in the future we can expect this specification to be extended to more modest models.
• 3.1. The successor to the UFS 3.0 standard, officially introduced in early 2020. It is positioned as a specification created specifically for high-performance mobile devices and aimed at increasing speed while minimizing power consumption. To do this, UFS 3.1 has a number of innovations: a non-volatile Write Booster cache to speed up writing; special DeepSleep power saving mode for relatively simple and inexpensive systems; as well as the Performance Throttling Notification feature, which allows the drive to send overheating signals to the control system. In addition, this standard may additionally provide support for the HPB extension, which improves reading speed.
• 4.0. UFS 4.0 doubled the throughput per lane (23.2 Gbps per lane) and improved energy efficiency by about 46% (compared to the previous 3.1 specification). UFS 4.0 standard memory modules provide maximum read speed up to 4200 MB/s, write speed up to 2800 MB/s. The high bandwidth makes the memory standard ideal for 5G smartphones.

The type of removable memory card slot.

In itself, the presence of such a slot allows you to expand the built-in storage of the device. This feature is especially useful given that large built-in drives are quite expensive — noticeably more expensive than removable cards. At the same time, we note that the design may provide certain restrictions on working with memory cards — for example, the inability to install an application on this card. These restrictions are usually directly related to the operating system used. And the speed of those cards is noticeably lower than that of the built-in storage. Therefore, there are phones without a memory card slot, so that there is nothing third-party in the operation of the device.

Separately, we note that in some devices for 2 SIM-cards, the slot for a memory card can be combined with a slot for a second SIM card. See "Card Slots" for details; here we note that if you want to use 2 SIM and a memory card at the same time, you should choose a device with a dedicated slot for a memory card.

As for the types of cards, microSD cards are the most popular nowadays: they are quite compact, inexpensive and available in a variety of volume options. Some Huawei smartphones use a different standard – Nano Memory (colloquially Nano SD). Among the advantages of such cards are a miniature size (corresponds to nano...SIM), high capacity (64 GB, 128 GB and 256 GB options were initially presented), as well as high speed (from 90 MB / s). On the other hand, most often they are installed not in a separate slot, but instead of a second nanoSIM card.

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 the device when passing the AnTuTu Benchmark performance test.

AnTuTu Benchmark is a comprehensive test designed specifically for mobile devices, primarily smartphones and tablets. It checks 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. And high-performance by AnTuTu rating are smartphones that score over 750K points

Like any benchmark, this test does not give absolute accuracy: the same device can show different results, usually with deviations within 5 – 7%. These deviations depend on many factors that are not directly related to the system — from the load of the device with third-party programs to the air temperature during testing. So, it is possible to speak about a significant difference between the two models only if the difference in their indicators goes beyond those 5 – 7%.

The result was shown by the device when passing the Wild Life (Extreme) performance test (benchmark) from 3DMark.

The Wild Life (Extreme) benchmark offers two ways to test graphics performance: a quick test that evaluates instantaneous performance, and a longer test that subjects the device to sustained load. This way one can evaluate how stable performance remains and does not drop due to overheating or throttling. The benchmark is cross-platform, which makes it possible to compare devices running different OSs and even different classes (for example, smartphones and laptops).

It is important to understand that this test does not provide absolute accuracy. The same device can show different results — they depend on many factors not directly related to the system. The error caused by these factors is often on the order of 5–7%. So we can talk about a significant difference between the two models being compared if the difference in performance goes beyond the mentioned error.
