Comparison Apple iPad 2025 256 GB vs Apple iPad Air 11 2024 256 GB

Percentage of screen coverage of the DCI-P3 color model.

This space has a wider range of colors than the standard sRGB triangle. In general, the DCI-P3 color space corresponds to the Adobe RGB model, but with a red shift. In practice, a high coverage rate means high-quality color rendition of the screen and allows you to use the tablet for design tasks.

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 number of individual cores provided by the tablet processor.

The core is the part of the processor that executes a single instruction stream. Accordingly, the more cores, the more threads the processor can simultaneously process and the higher its performance (ceteris paribus). On the other hand, numerous cores is not always an indicator of a high class processor and tablet as a whole. First, the actual performance of the chip depends on many other factors, and advanced dual-core processors often outperform inexpensive quad-core processors. Secondly, the development and cheapening of technologies has led to the fact that simple quad-core CPUs have become quite affordable even for low-cost devices. And even eight-core processors, which at one time were an unequivocal sign of advanced models, are increasingly found in relatively inexpensive tablets; the same can be said about relatively recent processors with 10 cores. However it is worth noting that in such chips, the cores can be divided into main (with high performance) and additional (used in tasks that do not require power). For example, 8 cores can be divided into 4 main and 4 additional cores. However, such a division is often not a disadvantage, but an advantage: numerous full-fledged cores is rarely required in fact, and reduced power saves energy and improves battery life.

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 amount of random access memory (RAM) installed in the tablet. This memory is used for direct data processing, and therefore its volume is one of the main indicators of system speed and power. However note that the optimal amount of RAM strongly depends on the OS used — different systems and even different versions of the same "OS" can vary greatly in terms of consumed resources. But models on the same OS can be compared with each other in terms of the amount of RAM.

As for specific values, indicators in 1 GB or less in our time are definitely a sign of a weak tablet. 2 GB and 3 GB can be called the entry level, 4 GB and 6 GB are middle class, and in the most advanced models, 8 GB, or even 16 GB can be installed (or even more) RAM.

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 bandwidth 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.

— microUSB. A smaller version of the USB connector, widely used in modern tablets as a universal interface. MicroUSB is used primarily to charge the battery and connect the device to a computer, and with USB OTG support, flash drives and other accessories are connected to it (of course, an adapter is required to work with a full-size USB plug). This connector is gradually being replaced by a more convenient and advanced USB-C (see below), but microUSB is still very far away from the complete disappearance.

— USB-C.It has similar dimensions to microUSB (see above) and replaced it, but differs in the design of the connector – it is symmetrical, which allows you to connect the plug to either side. In terms of application, this interface is also similar to microUSB, with the adjustment that USB-C often supports the advanced USB 3.2 gen2 standard, which provides speeds up to 10 Gbps. In addition, it is easier to implement fast charging through such a connector — some of the charging technologies were originally created for USB-C.

— USB4. A high-speed revision of the USB interface introduced in 2019. It uses only symmetrical USB-C connectors and does not have its own data format — instead, such a connection is used to transfer information according to several standards at once: USB 3.2 and DisplayPort as mandatory, as well as PCI-E as an option. Another feature...is that USB4 is based on the Thunderbolt protocol. It is also worth noting that this USB revision allows connecting devices in a daisy chain and by default supports Power Delivery technology, which allows you to optimize the process of charging external gadgets (provided that they also implement this technology).

The maximum data transfer rate for such a connector should be at least 10 Gbps, in fact, options for 20 Gbps and even 40 Gbps are often found (depending on the technologies and standards supported by a particular port). At the same time, the USB4 inputs are quite compatible with the peripherals of the USB-C connector.

— USB 2.0. Full size USB port 2.0 compliant. Such a port allows you to connect ordinary USB peripherals to the tablet — for example, flash drives or keyboards; however, due to its large size, it is rare, mainly in business models and in "hybrids" equipped with docking stations (in such cases, the port can be placed on the docking station). Version 2.0 supports data transfer rates up to 480 Mbps and is still quite popular, although it is gradually being replaced by more advanced standards — primarily USB 3.2 (see below).

— USB 3.2 gen1. USB version, formerly known as USB 3.1 gen1 or USB 3.0. Utilizes a traditional full-size USB port and delivers speeds up to 4.8Gbps — 10 times faster than the previous 2.0 version — as well as more power. At the same time, it is quite possible to connect USB 2.0 peripherals to such connectors.

— HDMI. A digital interface specially designed for broadcasting HD content: high-definition video and multi-channel audio. It is very popular in video technology, in particular, it is used in almost all modern TVs, it is often found in projectors, media players, etc. So HDMI support will be very useful if you plan to broadcast video from a tablet to an external screen. In portable technology, it is usually not a full-size connector that is used, but a reduced miniHDMI or microHDMI, however, finding a cable for such a port is not a problem.

— Mini-jack (3.5 mm). Standard 3.5mm mini-jack. Such a plug is used by the vast majority of modern wired headphones, headsets and portable speakers, therefore, in most tablets, it is the 3.5 mm port that plays the role of an audio jack. However if there are no problems with headphones and speakers, then compatibility with headsets needs to be specified separately — these devices have their own connection specifics. Also note that there are tablets without a 3.5 mm jack — they are usually designed for specialized accessories connected via a proprietary connector, or for wireless Bluetooth audio equipment.
