Comparison Xiaomi Pad 7 Pro 256 GB / RAM 12 GB vs Xiaomi Pad 7 256 GB / RAM 12 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 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 700K 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 Wild Life (Extreme) performance test (benchmark) from 3DMark.

The Wild Life (Extreme) benchmark offers two ways to test graphics performance: a quick test evaluates instant performance, while a longer test subjects the device to a long-term load. This allows you to evaluate how stable the performance remains and does not drop due to overheating or throttling. The benchmark is cross-platform, so it is possible to compare devices with different operating systems and even different classes (for example, tablets and laptops).

It is important to understand that this test does not provide absolute accuracy (as, indeed, any other benchmark). 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 about 5 - 7%. So we can talk about a significant difference between the two compared models only if the difference in indicators goes beyond the mentioned error.

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.

Wi-Fi is a must for modern tablets. This interface can be used both for connecting to local networks or the Internet (via a home router, public access point, etc.), and for direct communication with other devices (for example, remote control of a camera or broadcasting video to a TV). And tablets with 3G/LTE modules (or with the ability to connect an external cellular USB modem) can also work as an access point, “distributing” mobile Internet to other devices with Wi-Fi.

The Wi-Fi standard primarily determines the maximum data transfer speed (the actual speed is usually much lower). The most modest of the current Wi-Fi 3 standards (802.11g) provides speeds of up to 54 Mbit/s, but it is considered outdated and is extremely rare as the main one. Wi-Fi 4 (802.11n) with speeds of up to 300 Mbit/s, and Wi-Fi 5 (802.11ac)(up to 6.77 Gbit/s) have become much more widespread. Devices supporting Wi-Fi 6 (802.11ax) and Wi-Fi 6E are also gaining popularity, where connection speeds already reach 10 Gbps, and a number of solutions have been introduced to optimize the simultaneous operation of several devices on one router.

The latest version for 2024 is 802.11be - Wi-Fi 7. The technology, like the previous Wi-Fi 6E, is capable of operating in three frequency ranges: 2.4 GHz, 5 GHz and 6 GHz. At the same time, the maximum bandwi...dth in Wi-Fi 7 was increased from 160 MHz to 320 MHz - the wider the channel, the more data it can transmit. The IEEE 802.11be standard uses 4096-QAM modulation, which also allows more symbols to be accommodated in a data transmission unit. From Wi-Fi 7 you can squeeze out a maximum theoretical information exchange speed of up to 46 Gbps. In the context of using wireless connections for streaming and video games, the implemented MLO (Multi-Link Operation) development seems very interesting. With its help, you can aggregate several channels in different ranges, which significantly reduces delays in data transmission and ensures low and stable ping. And Multi-RU (Multiple Resource Unit) technology is designed to minimize communication delays when there are many connected client devices.

Separately, we note that, in addition to the directly specified Wi-Fi standard, modern tablets usually support a number of earlier versions. The same principle is used in most Wi-Fi equipment, so, as a rule, there are no problems with version compatibility.

— The number of lenses. The characteristics of the main (rear) camera of the tablet are represented primarily by the number of modules, which in most cases are 1, but there are also tablets with a dual camera.

— Resolution. The second important factor of the camera is the number of megapixels. Many really believe that the more MP, the better the quality of filming. However, this is not entirely true: only the maximum resolution of the resulting images depends on the resolution of the matrix, and their quality is determined by many other parameters. However a large sensor resolution may be a sign of an advanced camera, but this is not necessary — two "eyes" with the same number of megapixels can radically differ in the quality of shooting. Rear cameras in tablets may well be used for photo and video shooting; therefore, they have cameras of 8 MP, 10 MP and even higher (12 and 13 MP).

— Autofocus. For focus in such cameras, a movable lens system controlled by automation is responsible. It takes some time for the automation to work, and the lenses themselves turn out to be more complicated and more expensive than optics with a fixed focus (fixed lenses that are initially set to a large range of distances). However, the quality of the pictures i...s disproportionately higher than that of cameras without autofocus, and the systems themselves are constantly being improved, and their response time is increasingly approaching instantaneous.

— Flash. Flash significantly expands the capabilities of the camera. First of all, it allows you to shoot in low light conditions; in this case, the backlight, usually, can also be used in the constant glow mode — for video shooting. The second situation where a flash can come in handy is backlighting when the subject is in shadow. In addition, in many tablets, the flash LED can also be used as a regular flashlight, without a camera.

The resolution and maximum frame rate provided by the main camera when shooting UltraHD (4K) video at normal speed, without using slow motion (if available).

UHD 4K is the most advanced high-definition video standard in widespread use (more advanced standards exist but are not found on tablets).

The frame rate, in turn, determines how smooth the video will look, how clearly fast moving objects will be visible in it. With normal (not slow-motion) shooting in modern HD standards, including UHD, two options are actually used - 30 fps and 60 fps. The second option allows you to achieve very smooth video, with good motion detail in the frame and almost no blurring in dynamic scenes. However, it does affect the price.
