Comparison Lenovo Tab P10 32 GB / LTE vs Lenovo Tab 4 10 Plus 16 GB

The operating system (OS) that the tablet runs on.

The most popular operating systems in modern tablets are such operating systems as Android of different versions,iPadOS (modern version of iOS), as well as Windows 10 and Windows 11. Here is a more detailed description of the different options:

— Android. Free open source OS from Google. Used by almost all modern manufacturers except Apple. Presented on the market in many versions — in particular, Android 10 Q, Android 10 Go Edition, Android 11 R, 11 Go Edition, Android 12, Android 12 Go Edition, Android 13, Android 13 Go Edition, Android 14, Android 15. It is worth considering that at the time of the release of the device, one version of the OS could be installed, and at the time of sale it could be updated to a more modern one. Functionally, this OS is notable primarily for its full-fledged multitasking and an extensive set of available applications - in both of these points it surpasses both iOS and Windows. On the other hand, in general, the quali...ty of Android applications is somewhat lower than in iOS, and the system itself is designed mainly for entertainment use (unlike Windows). Initially, Android has tight integration with Google services - the Google Play app and content store, Gmail mail, Google Drive cloud storage, etc.; however, exceptions to this rule are possible. Note that the latest versions of this OS can be found on the market both in its original form and in one of two specific editions:

• Go Edition. Modification of Android, designed for inexpensive gadgets with "weak" hardware. Both the OS itself and standard applications (Assistant, Gmail, etc.) have been redesigned in this edition in such a way as to ensure reliable operation even with low computing power. At the same time, the developers tried to preserve the functionality of full-fledged Android as much as possible — however, some specific functions in the Go Edition were still not available (for example, standard maps do not support turn-by-turn navigation).
• HMS. Edition of Android without Google services, used in devices from Huawei. Due to US sanctions against China, this company cannot fully cooperate with Google — in particular, use Google services (Google Mobile Services — GMS) in its Android gadgets. As a replacement, HMS — Huawei Mobile Services were introduced. These services include Huawei ID, AppGallery, branded equivalents of Google's core services (assistant, browser, cloud storage, music/video, etc.), and app developer tools.

As for individual versions of Android, here are the main features of the options that are relevant nowadays:

• 7.0. Released in August 2016. In this version, for the first time, a multi-window mode appeared — the ability to display two windows with two different applications on the same screen — as well as a virtual reality mode.
• 7.1. Update version 7.0, released at the end of 2016. Introduced a number of minor improvements related to appearance and usability.
• 8.0. A major update that was released at the end of the summer of 2017. Among the most notable innovations are picture-in-picture multitasking when watching videos, compatibility with Bluetooth 5, support for applications for VoIP (Internet telephony) at the system level, the ability to group notifications into “channels”. It is also the first version of Android to feature a Go edition (see above).
• 8.1. An update released at the end of 2017. From the user's point of view, this version is almost the same as the original 8.0, the main innovations are related to minor improvements and bug fixes.
• 9.0. Update introduced in August 2018. One of the most notable changes was the look, with a redesigned design and more customization options. In addition, instead of the three standard buttons in the navigation bar, only one (Home) button is displayed by default, the Back button appears only when it is relevant, and the list of open applications is displayed by moving the Home button to the right. Other important innovations include optimization of background power consumption based on the actual frequency of use of applications, compatibility with additional types of biometric authorization (in addition to a fingerprint), and the ability to simultaneously use several cameras at once with one application.
• 10. Version released in September 2019. This version introduced an expanded set of full-screen gestures (with the possibility of optimization in individual applications — in particular, disabling gestures on certain areas of the screen to avoid conflicts), a "dark" display mode at the system level, a number of important security updates (including a separate encryption standard for weak devices that do not support the AES format at the hardware level), full support for 5G communications and improved capabilities for working with augmented reality. In addition, a number of solutions have been introduced to optimize work on foldable gadgets with a flexible screen.
• 11.The next major Anroid update, released in the fall of 2020. The most noticeable innovations in this version are related to messages and notifications. So, a separate section "Conversations" for messages was created in notifications, it also became possible to display various correspondence in the form of a "bubble" on top of any running application (Bubbles function). The functionality of the Do Not Disturb mode has been expanded — now you can add exceptions for individual correspondence to it. Other important innovations include a system tool for recording video from the screen (including fixing touch points), a single control centre for smart home components, quick switching between playback devices (phone speaker, wireless headphones, Smart TV, etc.) , built-in support for Android Auto, as well as advanced options for managing the access of individual applications to certain data.

— iPadOS. A branch of the iOS operating system that spun off in mid-2019, rebranded to match the large screens of Apple tablets. It is used exclusively on board "apple" devices and has a good degree of optimization for a specific hardware. Of the differences from the mobile version of the iOS operating system : a denser seating of icons on the desktop (6x5 format), improved multitasking, special gestures for working with texts, expanded functionality of the file manager and browser. In particular, Safari opens full versions of websites, not mobile ones.

— Windows. The operating system developed by Microsoft, originally created for PCs and laptops, but nowadays also used in tablets. Such tablets are considered mainly professional and business-class devices, they are well suited, in particular, for study and regular work with documents. The 11th revision of the operating system from Microsoft, which debuted in 2021, is now considered relevant. Of the qualitative improvements in the system, the taskbar has been redesigned, which is now located in the centre of the bottom edge of the desktop, new widget menus have been introduced, window resizing and position changes (Snap), and the operating system has become friends with Android applications. The system remains the prerogative of tablets for work and study with support for office and specialized programs written under Windows.

— HarmonyOS. Huawei's Universal Operating System, also known as Hongmeng. Provides operation of a wide range of devices: appliances from the smart home ecosystem, smartwatches, smartphones and tablets. Specifically, in the tablet league of gadgets, the Harmony OS system is a kind of add-on on top of Android without Google services. The app store for Harmony OS devices is called AppGallery.

In modern tablets, you can find other operating systems, in addition to those described above. However, these are very rare and specific systems that have not received significant distribution.

— Display diagonal. Size screen dimensions; traditionally indicated in ". Larger screens are easy to view and easy to touch. On the other hand, this parameter directly affects the dimensions, power consumption and price of the entire tablet (the increase in cost is often also due to the fact that a larger screen also requires a higher resolution). Rare birds from the family of modern tablets have 7-" screens; many of them look like slightly enlarged smartphones. Sizes of 8 " and 9 " can be considered basic. 10-" and 11-" diagonals are quite large for a consumer-class tablet; and screens of 12", 13", 14" and more are typical mainly for professional-level models.

– Resolution. Screen resolution on a tablet is the dimensions of the sensor in dots (pixels) horizontally and vertically. Based on this parameter, screens in modern tablets are conventionally divided into three categories: HD, Full HD, 2K and higher. The higher the display resolution, the clearer, more detailed and smoother the image it can reproduce. High resolution is especially important for large diagonal displays. At the same time, it significantly affec...ts the cost - both due to the high price of the screens themselves and due to the increased requirements for system performance.

— PPI. An abbreviation for "points per inch," i.e., "pixels per inch". This setting determines how many pixels are on a 1-" (2.54 cm) line drawn horizontally or vertically across the screen; it directly depends on the resolution and dimensions of the display. In general, the higher the PPI value, the clearer, smoother and, accordingly, the higher quality the picture on the screen will be. And at a certain pixel density, the human eye generally ceases to distinguish individual points, perceiving a completely smoothed image.

— Matrix type. The technology used to make the tablet PC display. Today the following types of matrices are used:

• — TN-Film(Twisted Nematic+Film). The oldest modern technology for manufacturing liquid crystal screens. Such matrices are characterized by a short response time, but have small viewing angles and provide relatively low image quality. For some time they were quite popular due to their low cost, but today they have practically disappeared from the scene due to the development and reduction in cost of more advanced technologies.
• — IPS(In Plane Switching). Such matrices are characterized by excellent color rendering and wide viewing angles in all viewing planes. Initially, they had a fairly long response time and were expensive, but technology does not stand still - improved versions of IPS are “faster” and inexpensive. Thanks to this, this type of sensor is found in all types of tablets, even among budget-class devices.
• — PLS(Plane to Line Switching). A type of sensor developed by Samsung engineers as an inexpensive and higher quality alternative to the original IPS, with increased brightness and contrast. For a number of reasons, it is used primarily in devices in the middle and higher price ranges.
• — LTPS(Low Temperature Poly Silicon). Technology for producing TFT displays using silicon. Indicators of brightness, contrast and viewing angles are at the level of screens made on the basis of IPS. A key feature of this technology is the ability to embed control electronics directly into the screen, but at the same time these displays remain light and thin. This technology is quite expensive to produce, but due to the fact that there is no need to use additional chips to control the image, the price of the end devices is at an acceptable level.
• — MVA. Abbreviation for "Multi-domain Vertical Alignment". One of the most popular types of VA technology today. It is a kind of transitional option between TN-film and IPS (see above), combining a number of advantages of both types. On the one hand, MVA matrices provide fairly high-quality color reproduction and deep blacks, on the other hand, their response time is not much lower than in TN-film. At the same time, such screens are not without drawbacks: when viewed strictly perpendicularly, the shades of black can be “blurred” and merge, and the color balance as a whole significantly depends on the viewing angle. It is not widely used on tablets.
• - AMOLED. An abbreviation for “Active Matrix Organic Light Emitting Diode,” that is, an active sensor based on organic light-emitting diodes. Unlike most other types of screens, the AMOLED sensor is itself a light source and does not require a separate backlight, which significantly reduces energy consumption. Moreover, such screens are characterized by high quality contrast and color reproduction, and the image on them is clearly visible even in bright external lighting. The main disadvantages of AMOLED are the complexity of production (as a consequence - high price), as well as the tendency to uneven wear ("burnout") of pixels during prolonged operation at high brightness, which can disrupt color rendition. On the other hand, it is very difficult to bring the display to such wear and tear, and AMOLED sensor manufacturers are constantly working on new modifications of the technology designed to eliminate these shortcomings.
• - Super AMOLED. A modified and improved version of AMOLED technology created by Samsung; LG produces such screens under the Ultra AMOLED brand. One of the key improvements to this technology is that in Super AMOLED screens the touch layer is built directly into the display (rather than being made separate). This had a positive effect both on the quality of color reproduction and image brightness, as well as on the accuracy and speed of the sensors. In addition, this type of screen is 20% brighter than original AMOLED, has 80% less glare and consumes 20% less energy.
• — Super Clear TFT. A technology created by Samsung together with Sony as an alternative to Super AMOLED displays (the demand for which was so high that manufacturers simply did not have enough capacity to produce the required quantity). Created on the basis of the usual TFT with some improvements and additions; In terms of image quality, Super AMOLED is somewhat inferior, but not by much, but the production of Super Clear TFT is much cheaper and easier.
• — OLED. Various types of matrices based on organic light-emitting diodes. In terms of features such as color rendering, contrast, power consumption, such screens are similar to the AMOLED ones described above; differences may lie in small details of technology. In general, OLED displays are quite advanced, they are found mainly in high-end tablet models. The main disadvantages of OLED screens are their high price (which, however, is constantly decreasing as the technology develops and improves), as well as the susceptibility of organic pixels to burn out when broadcasting static images or pictures with static elements (notification panel, on-screen buttons, etc.) for a long time. ).

— Sweep frequency. The maximum refresh rate of the display, in other words, the highest frame rate that it can effectively reproduce. The higher this indicator, the smoother and smoother the image is, the less noticeable the “slideshow effect” and blurring of objects when moving on the screen. At the same time, it is worth considering that a refresh rate of 60 Hz, supported by almost any modern tablet, is quite sufficient for most tasks; Even high-definition videos hardly use high frame rates these days. However, high refresh rates - 90 Hz, 120 Hz, 144 Hz - can be useful in games and some other tasks; it also improves the overall experience of the OS interface and applications - moving elements in such interfaces move as smoothly as possible and without blurring.

– HDR. Technology that allows you to expand the dynamic range of the screen. In this case, we mean a range of brightness - simply put, the presence of HDR allows the screen to display brighter whites and darker blacks than on displays without support for this technology. In practice, this gives a noticeable increase in picture quality: the saturation and fidelity of the rendition of various colors improves, and details in very light or very dark areas of the frame do not “drown” in white or black. However, all these advantages become noticeable only if the content being played is originally recorded in HDR. Nowadays, several varieties of this technology are used, here are their features:

• HDR10. Historically the first of the consumer HDR formats, it is extremely popular today: in particular, it is supported by almost all streaming services with HDR content and is standardly used for such content on Blu-ray discs. Provides 10-bits color depth (more than a billion shades). At the same time, on devices with this technology, you can also play HDR10+ format content (see below) - except that its quality will be limited by the capabilities of the original HDR10.
• HDR10+. Improved version of HDR10. With the same color depth (10 bits), it uses so-called dynamic metadata, which allows you to transmit information about the color depth not only for groups of several frames, but also for individual frames. Thanks to this, an additional improvement in color rendering is achieved.
• Dolby Vision. An advanced standard used particularly in professional cinematography. It allows you to achieve a color depth of 12 bits (almost 69 billion shades), uses the dynamic metadata mentioned above, and also makes it possible to transmit two image options at once in one video stream - HDR and regular (SDR). At the same time, Dolby Vision is based on the same technology as HDR10, so in modern electronics this format is often combined with HDR10 or HDR10+.

— Gorilla Glass. Special tempered glass used to cover displays in modern gadgets, including tablets. It is characterized by increased resistance to scratches and impacts; but the specific properties of the Gorilla Glass coating depend on its version. This parameter can also be specified in the tablet's specifications; Here are the most current versions for today:

• Gorilla Glass v3. Released in 2013, but still found in modern devices. This is primarily due to its outstanding scratch resistance: according to this indicator, the third version of the “gorilla” remained unsurpassed right up to 2020 (and Gorilla Glass Victus, which took the lead, is still practically not used in tablets).
• Gorilla Glass v4. Coating created in 2014. The main emphasis during development was on impact resistance, due to which this indicator, compared to the previous version, doubled (with a glass thickness of only 0.4 mm). But the scratch resistance has decreased somewhat.
• Gorilla Glass v5. Version introduced in 2016. Impact resistance, compared to its predecessor, has increased by 1.8 times, due to which such glass remains intact in 100% of cases of a fall from a height of 1.2 m (on a flat hard surface) and in 80% of cases of a fall from a height of 1.6 m. Scratch resistance has also improved somewhat, but this material still does not reach the performance levels of v3.
• Gorilla Glass v6. 2018 version with a focus on improving impact resistance. Twice stronger than version 5, guaranteed to withstand single drops from a height of 1.6 m and multiple drops (up to 15 times in a row) from a height of 1 m.
• Gorilla Glass Victus. After v3, this is the first version of Gorilla Glass where the creators paid as much attention to scratch resistance as shock protection. Victus glass debuted in 2020. Shock resistance for it is declared at the level of 2 m for a single fall and 1 m for multiple falls (up to 20 times in a row).
• Gorilla Glass Victus+. An improved modification of Gorilla Glass Victus, released in 2022. Close to ceramics in terms of scratch resistance. Thus, according to the Mohs mineral scale of hardness, glass begins to scratch at level 7/10, while the original Victus version scratches at level 6/10.

This parameter shows how much of the tablet's front panel area is on the display. The higher the display/body ratio, the thinner the frames and the more compact the tablet (with the same diagonal), the more elegant and aesthetically pleasing it looks. This indicator is also important when holding the tablet with both hands at once (for example, in games): thin frames or even frameless models allow you to reach further with your fingers without removing your hands from the device.

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.

The volume of the tablet's own built-in storage. The larger it is, the more information (programs, games, movies, photos, etc.) can be stored on the tablet without resorting to removable media, rewriting to other devices, etc. At the same time, the amount of built-in memory significantly affects the cost. Therefore, some models are available in several versions, differing only in the capacity of the drive. And the variety of built-in memory is quite wide: from 16 GB to 1024 GB with a 2-fold increase ( 32 GB, 64 GB, 128 GB, 256 GB, 512 GB).

Note that this paragraph indicates the total amount of internal memory. The operating system and default programs also take up space in it; therefore, the volume of the drive actually available to the user will inevitably be less than the total.

Many tablets allow you to add memory cards to the built-in drive (see below). Such cards are relatively inexpensive, but they are much slower, and the ability to work with them may be limited by the manufacturer — for example, not all tablets with this function allow installing applications on removable media.

The largest amount of memory card with which the tablet is able to work correctly. For more information about the cards themselves, see "Memory Card Slot"; here we note that capacious media often use advanced technologies that are not supported by early models, and sometimes tablets 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 — for example, work with 8 GB of media with the claimed 4 GB of maximum capacity. However, it is worth focus on official data, because. if they are exceeded, normal operation with the card is not guaranteed.

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 500,000 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 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.
