Comparison Samsung Galaxy A30 32 GB / 3 GB vs Samsung Galaxy A50 64 GB / 4 GB

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 765G, Snapdragon 778G, Snapdragon 7 Gen 1, Snapdragon 7+ Gen 2, 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. And Mediatek has a low cost series MediaTek Helio P and a line of advanced chipsets MediaTek Dimensity (Dimensity 1000, Dimensity 8000, Dimensity 9000).

Knowing the name of the CPU model installed in the smartphone, you can find detailed data on a particular 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 a...nd 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 volume of storage installed in the phone.

This volume directly determines how much data can be stored on the phone without using removable memory cards. This indicator is especially important for models that don't have memory card slots. However, even if memory cards are supported, built-in storage is still preferable: at least it works faster, and it usually has fewer restrictions on its use (in particular, most smartphones allow you to install applications only on storage).

As for specific volumes, the actual minimum for a modern smartphone is 32 GB; less “capacious” devices are becoming increasingly rare these days. 64 GB is considered a comfortable minimum, 128 GB is considered average indicator, 256 GB - above average. Some high-end devices are equipped with 512 GB and even 1 TB< /a>.

We also note that the actual amount of memory available to the user will inevitably be somewhat less than the total, since part of the drive is occupied by operating system files.

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 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 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.
