| Processor (CPU) The primary function of a mobile device's processor (CPU) is to interpret and execute instructions contained in software applications. | ARM Cortex-A9 |
| Processor size The size (in bits) of a processor is determined by the size (in bits) of the registers, address buses, and data buses. 64-bit processors have higher performance compared to 32-bit processors, which in turn are more powerful than 16-bit processors. | 32 bit |
| Instruction Set Architecture Instructions are commands with which the software sets/controls the operation of the processor. Information about the instruction set (ISA) that the processor can execute. | ARMv7 |
| Level 1 cache (L1) Cache memory is used by the processor to reduce access time to more frequently used data and instructions. L1 (level 1) cache is small in size and works much faster as system memory, and other levels of cache memory. If the processor does not find the requested data in L1, it continues to look for it in the L2 cache. On some processors, this search is performed simultaneously in L1 and L2. | 32 kB + 32 kB (kilobytes) |
| Level 2 cache (L2) L2 (level 2) cache is slower than L1 cache, but in return it has a higher capacity, allowing it to cache more data. It, like L1, is much faster than system memory (RAM). If the processor does not find the requested data in L2, it continues to look for it in the L3 cache (if available) or in RAM memory. | 1024 kB (kilobytes) 1 MB (megabytes) |
| Number of processor cores The processor core performs program instructions. There are processors with one, two or more cores. Having more cores increases performance by allowing multiple instructions to be executed in parallel. | 2 |
| CPU clock speed The clock speed of a processor describes its speed in terms of cycles per second. It is measured in megahertz (MHz) or gigahertz (GHz). | 1000 MHz (megahertz) |
| Graphics Processing Unit (GPU) The Graphics Processing Unit (GPU) handles calculations for various 2D/3D graphics applications. IN mobile devices ah it is used most often by games, consumer interface, video applications, etc. | PowerVR SGX543 MP2 |
| Number of GPU cores Like a CPU, a GPU is made up of several working parts called cores. They handle graphics calculations for various applications. | 2 |
| Volume random access memory(RAM) Random access memory (RAM) is used by the operating system and all installed applications. Data stored in RAM is lost after the device is turned off or restarted. | 512 MB (megabytes) |
| Type of random access memory (RAM) Information about the type of random access memory (RAM) used by the device. | LPDDR2 |

Specific Absorption Rate (SAR)
The SAR level refers to the amount of electromagnetic radiation absorbed by the human body while using a mobile device.
| SAR level for body (EU) The SAR level indicates maximum amount electromagnetic radiation to which the human body is exposed when holding a mobile device at hip level. Maximum permissible value The SAR for mobile devices in Europe is 2 W/kg per 10 grams of human tissue. This standard established by the CENELEC committee in compliance with the ICNIRP guidelines of 1998 and IEC standards. | 0.76 W/kg (Watt per kilogram) |
| Body SAR level (US) The SAR level indicates the maximum amount of electromagnetic radiation to which the human body is exposed when holding a mobile device at hip level. The highest permissible SAR value in the USA is 1.6 W/kg per 1 gram of human tissue. This value is set by the FCC, and the CTIA monitors mobile devices' compliance with this standard. | 0.99 W/kg (Watt per kilogram) |
Two cameras for FaceTime video calls and HD video recording. Dual-core Apple A5 processor. The same 10 hours of battery life. And at the same time a thinner and lighter body. The iPad just got more awesome. And even more unique.
Thinner. Easier.
And more great ideas.
Anyone who has touched iPad 2 will have a hard time letting go of it. This was the task when developing its new design. iPad has become 33% thinner and almost 15% lighter, making it even more comfortable to hold. Watching websites and movies, checking email and reading books on iPad 2 is so natural that you simply forget about all the incredible technologies embodied in it.
Dual-core A5 processor.
Speed. And once again speed.
With two powerful cores in one A5 processor, iPad can do twice as much work in the same amount of time. You'll undoubtedly notice the difference when you surf the Internet, watch movies, make FaceTime video calls, play games, and switch between apps. Multitasking is smoother, apps load faster - everything works even better.
Super fast graphics.
To the delight of gamers.
Power graphics system iPad 2 is almost nine times larger, making games more realistic. In addition, upgrading the processor had a positive effect on the operation of applications, especially those related to video. You'll notice this when you look at photo collections, edit videos in iMovie, or include animations in Keynote.
Battery for an active life.
Despite the fact that the iPad has become lighter and thinner, its battery still lasts up to 10 hours. This is enough for a flight across the Atlantic, or for a whole night of watching movies, or for a week of use on the way to and from work. Economical processor A5 and iOS system They prevent you from wasting energy, so you can hit the road without any problems.
Two cameras. Big hello to FaceTime for iPad.
The iPad has two cameras: one on the front panel, the second on the back. They seem tiny, but are actually capable of a lot. The cameras are designed for FaceTime video calls, and they work in pairs. Not only can you talk to your loved ones, but you can also see them smile at you. The front camera allows you and the other person to see each other. If you switch to the rear camera, you can show where you are and what is happening around you. If the scene is worthy of attention, turn the shooting mode to rear camera iPad. The camera works in HD format, so every video you make will become a small masterpiece. And with Photo Booth you can take fun photos. This is by far the most fun use for FaceTime.
LED backlit screen.
Enjoy the views.
Awesome big screen iPad is 9.7 inches of high-quality photos, movies, web pages and more. LED lights gives a clear, bright and vibrant picture. Even in low light, such as on an airplane. And you can hold the iPad however you want. It supports vertical and horizontal orientation. Even if you turn the iPad upside down, the image on the screen will still be displayed correctly. Thanks to IPS technology(in-plane switching) viewing angle is 178°. Unfold the screen and show it to someone on the other side of the room, or look at it together with the person sitting next to you - it will be perfectly visible to everyone.
Multi-Touch.
Everything is at hand.
The secret of good technology is that it should be completely invisible, as if it were not there. Multi-Touch technology on the iPad is implemented exactly this way. Every action is performed with your fingers, so everything you do - browsing websites, typing emails, reading books and scrolling through photos - becomes easier and much more interesting. How does this technology work? When you touch the screen with your fingers, it detects your touch using electrical fields. And then instantly transforms your taps, swipes, pinches, and swipes into realistic movements of objects on the screen. Everything is elementary.
iOS 4.
The world's most advanced mobile operating system.
iOS 4 is the operating system for the iPad (as well as the iPhone and iPod touch). It allows you to find, read and view everything you need with simple taps. It's packed with powerful, innovative, and fun built-in apps that you use every day—many times a day. iOS 4 is also the platform that powers over 65,000 amazing iPad apps. It is fully integrated with the iPad hardware and features a high level of security, reliability and performance. iOS 4 is the reason why other devices can't even match the iPad.
Instant on.
Magic with one click.
Take your iPad, press the Home button, and it will instantly wake up from sleep mode. iPad has efficient and reliable flash storage that provides fast access to the data. The system comes to life by itself.
Wi-Fi and 3G.
Two great ways to stay connected.
Every iPad supports the latest wireless technology 802.11n. The device automatically finds available Wi-Fi networks- just a few taps are enough to connect to the network. There is also a 3G iPad model. If you find yourself in an area where Wi-Fi networks are not available, such as while camping or on the road, you can still surf the Internet, check email, or get driving directions.
Gyroscope, accelerometer and compass.
iPad senses your every move.
Thanks to the built-in accelerometer, you can turn the iPad horizontally, vertically, even upside down, and the image on the screen will still be displayed correctly. In addition to the accelerometer, iPad 2 features a three-axis gyroscope and compass. They all determine the iPad's location, its position relative to the ground, and its movement parameters. Games, maps and applications will now take into account every turn, tilt and movement. This is a huge step forward for video games. And the beginning of a new era for applications.
Video duplication. Your iPad is on display for everyone to see.
Video duplication - new feature iPad. It can be used for all applications, videos, movies, photos that you want to show to the general public. Simply connect the Apple Digital AV Adapter or VGA Dock Adapter (sold separately), and your HDTV or projector's large screen turns into an iPad screen. One connector and you're done. Everyone will see what's on your display, even if you rotate your iPad and zoom in on your photos.
AirPrint. Print wirelessly.
Print emails, photos, web pages, and documents wirelessly from iPad. No need to download apps, install drivers or connect cables. Just a few taps - and what you see on the iPad screen ends up on paper.
- Displays iPad Pro 12.9 inches and 11 inches are rectangles with rounded corners. The display diagonal is measured without taking into account the curves and is 12.9 inches for the 12.9-inch iPad Pro and 11 inches for the 11-inch iPad Pro. The actual viewing area is smaller.
- The amount of available space is less than stated and depends on various factors. Standard configuration(including iOS and pre-installed apps) takes approximately 10 to 12 GB depending on device model and settings. Pre-installed applications occupy about 4 GB; they can be deleted and downloaded again. Tariff plan cellular communications sold separately.
- Size and weight vary depending on device configuration and manufacturing process.
- To communicate using FaceTime, both users must have FaceTime-enabled devices and be connected to a Wi-Fi network. Availability of FaceTime over cellular networks varies by carrier; Data charges may apply.
- Data plan required. Gigabit networks Class LTE, 4G LTE Advanced and 4G LTE are not available in all regions or on all carriers. Speed calculated based on theoretical bandwidth and depends on local conditions. Detailed information about support LTE networks Available from your carrier or from .
- Cellular plan must be purchased separately. The model you purchase is configured to work with a specific cellular network technology. Contact your carrier for cellular plan availability and compatibility.
- Not all telecom operators support cards Apple SIM and eSIM. Contact your carrier for more information. Not available in China. eSIM technology is supported on the 11-inch iPad Pro and 12.9-inch iPad Pro (3rd generation). Apple SIM technology is supported on iPad Pro 10.5-inch, iPad (5th generation or later), iPad Air 2 and iPad mini 3 or later.
- Battery life depends on device settings and usage. More details on the page
My task is very simple, because there was already an article about the announcement, it was discussed quite a bit on the forum, and all I had to do was calmly tell what I saw when I opened the small box. Yesterday you could take a closer look at the iPad 2 at a first glance, today in a little more detail. A little, because the iPad is not a thing about which you can write a complete and very full review. Everything very much depends on the software, because this tablet turns into game console or a typewriter precisely thanks to additional programs- so think about which particular hypostasis of the device to write about. It’s an amazing thing, a phenomenon where consumers pay money for a piece of iron, only to then rack their brains about how to use it. Of course I have an iPad. A new interesting toy comes out, and he gets it out of the nook. You need to take something like a presentation with you - again into battle. Rescue in traffic jams. Library. Sometimes it sits idle for weeks. But without it, it’s hard to imagine your set of the best gadgets of all time.
Other scenarios also happen literally before our eyes - a person buys an iPad and does not understand what to do with it. Children take away the toy and quickly find what to do (there are plenty of games). Or, the girl takes it away. It happens. To sit on VKontakte or Facebook. You never know.
Design, construction
The device resembles iPod Touch, as if they took many, many “cars”, put them together, it turned out second iPad. Thin, but there are more visual deceptions here - the rounded edges to some extent hide the true thickness of the device. At first, you take it in your hands, and it seems that it is much smaller and lighter than the first iPad. To some extent this is true, but even if you look at the photographs, you will see that the difference in size is small. But there is a difference in weight. The first model weighed 680 grams, dimensions were 242.8 x 189.7 x 13.4 mm. The iPad 2 weighs 601 grams and measures 241.2 x 185.7 x 8.8 mm. Again, the difference in thickness is not very noticeable.
Comparison with iPad:
The material is still the same, rough aluminum; an oleophobic coating has appeared on the display protection. But, given the size of the screen, fingerprints still remain, and they are clearly visible.
Due to the fact that the ends are beveled, strange things happen to USB cables. In the photo you can see how the connector is arranged here. So, for some reason only the cable from the box is suitable, the device simply does not accept others. Although I didn't find any differences. Supplied included network adapter, for Russia there will, of course, be the right plug.
I dealt with the version in the maximum configuration, Wi-Fi + 3G, 64 GB memory. The kit includes a paperclip for removing the SIM card slot; the slot is also not great; in the first iPad it was more convenient to insert it into place. Although, this is unlikely to be done often.
The design of the speaker is interesting, with a perforated area at the bottom of the case. Compared with first iPad The speaker became a little louder, a little better, but nothing more. And then, maybe, it seems to me.
Versions with 3G also have a black insert on the top of the case, which also houses the microphone hole. The 3.5 mm jack is also beveled, but there were no problems with various headsets.
Accessories for the first model are suitable for the iPad 2, but you need to take into account one simple fact: not everything is going smoothly with the connector; you will definitely have to try the add-ons before purchasing. Cases, if so simple models, cases, covers - fit without problems. I haven’t seen the new case from Apple yet; as soon as I get my hands on it, I’ll tell you more about this innovation.
The most important update, in my opinion, is the ability to choose a black or white iPad 2, the color of the frame changes. Let's just say, for girls and boys. Although, if we talk about the iPad for boys, then this is rather the first model - chopped shapes, you pick it up, feel the thing and all that.
Display
The display diagonal is 9.7 inches, resolution 1024 x 768 pixels, the impressions are only positive. Here some problem arose with the backlight at the bottom - everything was fine on the device in question. Excellent viewing angles, the screen is bright, juicy, equally suitable for gaming and browsing the Internet. By the way, about these pages. I tried to watch YouTube videos in our articles, and from time to time an error appears, something like “You do not have enough rights.” It seems simple task, but some problems.
Control
Everything is the same, the volume buttons and the lever on the end, you can program its action in the menu, this is either turning off the sound or disabling automatic image rotation. The button under the display has become softer, although this is probably just my imagination. The button on the top left remained in place, it was “pulled out” from the case, and is convenient to use.
Touchscreen magnificent, I have not yet seen a single tablet that is so easy to use.
Cameras
Added cameras on the front and rear panels, you can do a lot of things. First, use cameras for Facetime. The application icon is located on the desktop, working with it is very simple, you can simply add contacts - no problem. To call you need Wi-Fi connection. You can see how the program works in our video. You shouldn't wait for the crystal frequency, that's for sure. As with the iPhone 4, it is possible to switch camera views.
Another program for pampering is Photobooth, coming soon to Facebook and others in social networks there will probably be a ton of profile photos taken with it. The point is that you can choose any funny effect, take a photo - a self-portrait and immediately send it somewhere.
The camera on the back is not very good, the pictures are so-so. The video shoots well, the resolution is 1280 x 720 pixels.

Geotags are supported and focusing on an object you specify is possible.
Nutrition
The stated operating time is about ten hours when using a browser with a Wi-Fi connection. In any case, have iPad time The work is good, I haven’t heard anyone find fault with this yet. It seems like the screen is huge, and the processor is now dual-core, but the gadget works for a long time. Which is good news.
CPU
Apple processor A5 with clock frequency 1 GHz, dual-core, but that doesn’t tell us anything, does it? You can just see the difference.
I didn’t bother making another video about the speed of work - I’ll have time. But I can say one thing: when comparing iPad and iPad 2 head-to-head, Safari works much faster on the latter; for many, this is the main tool. Games launch faster. Switching between applications and using multitasking occurs faster. That is, you don’t even need to convince yourself - the difference can be seen with the naked eye.
For those who like to play, there is also good news, there is now a gyroscope, it’s very cool to drive races.
Communications
As you can see, the MTS SIM card was quickly recognized; let me remind you again - no unlocking is needed for the iPad. The Wi-Fi version looks very attractive for iPhone owners 3Gs and iPhone 4, because in iOS versions 4.3 there was a thing called “Personal Access Point”. I will write about this separately. But, in my opinion, if you are going to take it, then take the version with 3G. Unlike the Wi-Fi version, there is a digital compass (works in Google Maps, for example), aGPS.
You can connect everything to the TV, one more accessory for the device and an extra thirty dollars for you. I mean, you'll have to spend money on this adapter. It’s interesting how popular this function will be, how many iPad owners will want to connect their tablet to the TV. It would be interesting to hear opinions on the forum.
There are no problems connecting to access points; Bluetooth works with a regular or stereo headset without any problems.
Memory
Or 16 GB, or 32 GB, or 64 GB, everything is simple here - the more, the better. Watch TV series. Or store music. Who likes what more? By the way, the sound quality has not changed compared to the first iPad, I tried listening with Monster Turbine, everything is very similar.
conclusions
The following goals have been achieved. The entire civilized world is discussing again new tablet Apple. Tablets, it seems, are only made by Apple. All movements of competitors are blocked by a trump card, because any news about Motorola XOOM or new products from Samsung is blocked by a wave of everything about iPad 2.
For the company, I repeat, it was important to consolidate success, and it is absolutely clear that we are not having a revolution here, but an evolution, but this is enough to maintain interest. Will the iPad 2 be in demand? Yes. Should you upgrade your first iPad to an iPad 2? Only if you need cameras, a smaller body, speed - in my opinion, all this is not a reason to run to the store. You can use FaceTime on iPhone 4, the rest is not critical.
But, as practice shows, the arguments of reason often mean absolutely nothing to the consumer. We are all children. We all play with toys. Only they, forgive the banality, become more expensive over time. Apple employs real toy masters who are capable of delighting and delighting us endlessly - and I personally see further proof of their skill, right in the palm of my hand.
Over the past year, no company has introduced anything equal to the original iPad. Nothing that would be pleasant to pick up and would not want to give back.
Another milestone for Apple.
Another reason for competitors to scratch their heads.
The author expresses gratitude to the iCases.ru store for providing the iPad 2 for the test.
Sergey Kuzmin ()
In this article we will discuss one of the most important characteristics iPad – screen diagonals. This is the most impressive detail of the tablet that immediately catches your eye. During its existence, the Apple company has released many models of this device. And they all come with different sizes displays. Let's see how gadgets have changed according to this criterion over the years. Let's start the review with the very first lines - iPad 1, 2 and so on.
A tablet is a type of device whose display diagonal size is of great importance. The first generation, released 7 years ago, already came in a standard version, which took root for many years. The parameter in question did not change for gadgets until the 4th generation, although something new was added in terms of other screen characteristics:
- iPad 1 had a diagonal of 9.7 inches (in iPad 2 the diagonal was left the same as in iPad 3 and iPad 4), with a resolution of 1024x768, 132 ppi.
- iPad 2 – the same parameters in inches, exactly the same resolution and pixel density.
- iPad 3 - 100% higher resolution than the first and second line of devices, the same with pixel density.
- iPad 4 is all the same as its predecessor.
But regardless of the model, the picture on the display of Apple tablets has always been excellent. But technology is developing continuously and gadgets of the 3 and 4 line received a Retina display .
The four also increased the screen resolution and pixel density parameter. This made it possible to make the image look like the picture glossy magazine. Pixels are not visible at all, which adds realism. The developer made the 100% right choice by introducing this technology. Among 10-inch tablets, this device is considered the best. The only drawback is the lack of anti-reflective coating. This disadvantage was noted by many users on the forums.
The IPS matrix element included in models of lines 1 – 4 produces color scheme maximum naturalism and provides maximum viewing angles. Its quality is especially visible when compared with previous display options. Capacitive sensor has also been improved. In addition, a warmer color scheme and improved image detail have been added.
Display sizes of iPad Air, iPad Air 2
The further development of tablets was very interesting. The body has been radically improved, new shades have appeared. The frames were significantly reduced, but the display sizes remained the same (as in the fourth and other iPads).
More compact dimensions of the line iPad tablets Air brought them to more high level, made stylish and modern.
Characteristics of displays of Air model devices:
- iPad Air – 9.7 inches, Retina, resolution 2048×1536, 264 ppi.
- iPad Air 2 has exactly the same parameters as the first “air” tablet.
As you can see, everything remains the same. Only Retina technology is of interest. Thanks to it, the response period to touching the display and energy consumption have been significantly reduced.
iPad mini, iPad mini 2-4 screen parameters
The time has come to highlight tablets that are close to modern standards of top-end devices. The developer paused a bit with the display sizes and this innovation is for the better.
The mini versions have become widespread and are loved by many users. After all, carrying such a gadget with you is very comfortable, and its functionality is not inferior to ordinary models:
- iPad mini - 7.9 inches, with a resolution of 1024x768, pixel density 163 ppi.
- iPad mini 2 - the same diagonal, but the resolution and pixel density have been increased by 100%.
- iPad mini 3 - exactly the same performance as the second mini variation.
- iPad mini 4 - exactly the same as versions 2 and 3.
As can be seen from the characteristics presented above, the diagonals of mini devices are not at all the same as in 4 iPads and others standard versions. They are much smaller. The resolution setting is similar, but the number of dots is 1 inch larger.
Pro line tablets
In terms of “appearance”, the two variations of the gadget in this line are almost identical. Therefore, users here choose based on functionality, because not everyone needs a TV to carry with them all the time:
- Pro variation 1 - 9.7 inches, Retina, resolution 2732x2048, 264 ppi.
- Pro variation 2 – 12.9 inches, other parameters are exactly the same.
Today, these two models are the best, both in terms of picture quality and performance. The latest anti-reflective coating makes working in the sun comfortable.
Above was a historical background regarding the development of tablets from the Apple company in terms of display size. It's interesting how iPads will evolve in the future, but that's anyone's guess. But judging by the performance. For at least another 2-3 years, Pro will be at its best and will satisfy the needs of the most demanding users.
And since the subject of our conversation today is the second line of iPads, let’s take a closer look at the other characteristics of this line of tablets.
iPad 2 design
There has been no revolution since the release of the second generation of devices. Consumers were presented with the same product in a minimalist style, very neat, made of glass and aluminum materials. You may not like Apple devices, but you cannot deny that they are of decent quality. In terms of design, they are several steps ahead of similar gadgets from competitors. Let’s say you can’t put plastic products from Samsung Tab or Motorola XOOM, consisting of individual elements, collected together. If you have any doubts about this, just turn the Apple tablet in your hands and immediately feel the difference.
The rear part remained the same “indestructible”. It is made of scratch-resistant metal. The panel has now become almost flat - it narrows only towards the end part. The first line of tablets did not have this.
The Deuce is significantly thinner than its predecessor (and even the iPhone 4). Visually it seems that you can even scratch it, like a piece of paper. This effect is created thanks to the same narrowing towards the ends. In it, the developer used the same design idea as in MacBook Air, in which the minimum thickness parameters are only 3 millimeters.
The tablet also lost a little weight. True, only 6 grams compared to its predecessors, but still this is a positive result. However, at that time, according to this criterion, the iPad 2 was ahead of its competitor from the Korean company - Galaxy, which weighed 7 grams less. At the same time, its body was made of plastic, which does not add to its price.
iPad 2 equipment
Everything here is standard and predictable, nothing new. In the box with the second tablet, in addition to the device itself, the user found:
- charging element;
- USB cord;
- documentation;
- brochures and stickers with Apple logos.
The Apple company, as always, has not betrayed the principles of minimalism. The rather large box did not contain anything notable accessories. By the way, the adapter is for an American outlet. So, whether you like it or not, you will have to purchase an adapter.
Battery for the second tablet
The period of operation without additional recharging of devices of the second line is the same 10-12 hours. The same was true for the starter product of this type. And this is all during active use using wireless elements, while watching movies and listening to music tracks.
All this is impressive considering that we're talking about about a device with a nine-cell battery. According to these criteria, Apple's tablet has no competitors to this day. Similar gadgets from other companies operating on Android work for about 6 hours without recharging. It is especially pleasing that a long period of autonomous operation was preserved with a significant reduction in the thickness of the case.
And a little more about the display...
This element was already the pride of the company in the very first tablet. At that time he was the most best quality– our competitors had nothing like this. In the second generation tablet everything remains the same. Many fans of Apple products expected to see Retina technology in it, that is, a resolution increased by 400%. But for such parameters, the device did not have enough processor power and graphics element. In other words, a miracle did not happen. And if it happened, the starting price of the gadget would soar by at least 50%.
But this display has also become one of the best in terms of brightness, resolution and responsiveness to touch. It is not for nothing that any devices with a touch mechanism are usually compared with iPhones and iPads, because the latter have no equal.
However, there are also more significant distinctive points compared to the previous version and competitors. For example, thanks to the oleophobic layer, the display is not easily soiled. It is very difficult to stain it with touches. And if any dirt suddenly appears, it is easy to remove. Users have to clean the devices of the first line and tablets of competitors constantly.
Efficiency has increased in many areas - when surfing the Internet, when working with graphic elements. Separately, it is worth mentioning the increase in memory on board the second tablet to 512 megabytes. Of course, today such an indicator will seem ridiculous, but at that time it caused delight.
The operating system in this line of tablets, compared to the previous one, was also more advanced. She was an order of magnitude taller. Accordingly, the functionality has expanded, and the work has become faster.
The tablet performs all commands perfectly. This applies to the interface, a fast browser, no freezing or slowdown of programs, and lively playing video.
