Ipad 4 Review

Ipad 4 review

Today iPad 4 is considered the flagship of the older line of Apple tablets. If a laptop with a Windows / MacOS / Linux operating system is more suitable for work, then the iPad 4 does an excellent job with the entertainment part and using previously implemented developments.

Ipad 4 Review

Design and materials

Ipad 4 has as many as four design variations due to the possible support for mobile networks and the navigation module. You can distinguish the version of the apple tablet by the plastic black insert located at the top of the back of the device. There is also a white and black version of the iPad 4, by analogy with Apple smartphones and smart players from Apple.

The main difference between the tablet design and the smartphone is that it is rounded on the sides. It looks pretty impressive and is ergonomic to work with. Tempered glass front and anodized aluminum back.

Equipment

The box in which the tablet is packed practically does not differ from the previous generation, as well as the equipment itself. The main difference is the cable with the new Lightning connector. Here you can also find a USB charger, user manual and stickers 🙂 Everything is neatly packed in foil, everything is great! In the EU countries, the kit also includes an adapter from microUSB to Lightning.

Specifications

We will consider the hardware of the iPad 4 with support for the navigation and radio module, because this tablet is no different from its stripped-down version. It is worth noting that without a jailbreak from such an iPad 4 it will not be possible to call and send SMS, but it will only be possible to access the Internet via mobile networks.

The standard of the second generation of mobile networks is represented by both GSM and CDMA-module, the supported frequencies of which are respectively the following: 850, 900, 1800, 1900 and 800, 1900, 2100 MHz. The third generation is represented by the standard HSDPA (frequencies: 850, 900, 1900, 2100 MHz) and the CDMA2000 1xEVDO standard. Support for fourth-generation networks is provided by the LTE standard, which is presented in two variations. The first is characterized by frequencies of 700, 1700 and 2100 MHz, and the second. 700, 850, 1800, 1900, 2100 MHz. Supported SIM card standard. Microsim.

The dimensions of the device are as follows: 241.2185.79.4, and its weight is 662 grams. Yes, of course, this tablet will be inconvenient when working on weight, but it is not in the same weight category with the iPad mini;) The display of the device received an expansion of 15362048 pixels, and its diagonal is 9.7 “. It is clear enough, but does not match Retina.Display iPhone 5 due to lower pixel density.But if we take into account the fact that the user works with the tablet at a greater distance from the eyes, the differences in clarity and quality of the picture are almost invisible. By the way, their matrices are made using IPS technology, which provides excellent picture and wide viewing angles The protective glass of the display is durable and has a special oleophobic coating.

Ipad 4 holds the record for the amount of internal memory, because it has a model with 128 gigabytes. There is also a variation with 32, 64, and 16 gigabytes. The RAM is one gigabyte, which is quite enough for productive work and indulging in photographic heavy games. The set of wireless modules is identical to the one installed in the iPhone 5: Wi-Fi a / b / g / n with support for the functionality of an access point and BlueTooth 4.0.

The camera is installed similar to the one in the iPad 3 (or New iPad, as Apple likes to call it). This is a 5 megapixel module with support for FullHD recording. The front camera is only 1.2 megapixels, but it does a great job of its function: the ability to conference in 720p quality. Those who have already used FaceTime know what this is about;)

The work is provided by a powerful processor of Apple’s own design A6X, which has two cores and a clock speed of 1.4 GHz. Gaming applications on this device simply “fly”, because the 4-core photographic accelerator PowerVR SGX554MP4 is installed here. The set of sensors is pretty decent for a tablet: digital compass, gyroscope, accelerometer, GPSGLONASS.

Performance and software

Ipad 4 is considered the flagship among Apple tablets, and its performance can be the envy of every Apple device. All thanks to a 4-core photographic accelerator and a modified processor. Compared to the iPad mini, the performance is more than 2.5 times higher. The fourth generation of the older line of apple tablets supports the latest possible iOS software and will be in service for a long time.

Accessories

A large number of interesting and high-quality accessories are produced for the latest generation apple tablet: covers, protective films, carbon and vinyl stickers. In addition, Apple itself has released an excellent unique case called Smart Cover, which can really significantly improve the functionality and ergonomics of iPad 4.

Performance

Here we come to the main difference between iPad 3 and iPad 4. This is performance. The previous model ran on the Apple A5X SoC, which contained two ARM Cortex-A9 CPU cores at 1 GHz, as well as a PowerVR SGX 543MP4 quad-core GPU at 250 MHz. In the new SoC, the frequency of processor cores has increased to 1.4 GHz, while the frequency of the GPU to 300 MHz. The number of cores in both cases remained unchanged. However, if in the case of the Apple A5X, Cortex-A9 CPU cores were used, now (starting with the Apple A6) Apple itself has created CPU cores based on the ARMv7s architecture.

Let’s take a look at how the SoC change affected the iPad 4’s performance as the rest of the specs (RAM, screen resolution) remained unchanged.

Let’s start with the synthetic Linpack benchmark, which reflects CPU performance. It will allow us to understand how effective the new architecture of CPU cores is.

Well, we see that the difference is gigantic. Obviously, this cannot be explained solely by the increased CPU frequency. Apparently the updated architecture is really highly efficient.

Next we will have the SunSpider 0.9.1 browser benchmark. It tests the speed of the JavaScript engine in the browser and can be useful both for testing the CPU and for determining how comfortable it will be to view Internet pages on a given device. Note that we tested the iPad 3 with the current version of iOS 6, so the operating system itself and the browser were the same on both devices. On each device (previously cleared of cookies and loaded pages, as well as rebooted), the test was run three times. The table shows the best results.

So the iPad 4 is more than twice as fast as the iPad 3. Note that this is pretty close to the iPhone 5, but even better. Thus, at the moment, iPad 4 is the absolute record holder among ARM devices in this test. For comparison, here are the results of the main Android competitors.

In the GeekBench 2.3.6 multiplatform test, the iPad 4 also completely defeated its predecessor, but the competitors from the Android camp were generally no worse.

Perhaps this is because Geekbench is sensitive to the number of CPU cores. And in this parameter, both NVIDIA Tegra 3 and Samsung Exynos 4412 overtake Apple A6X. However, do not forget that this is a benchmark, but real applications, as a rule, do not use all four cores. Therefore, the victory of ASUS and Samsung tablets in this benchmark does not mean that it will be more comfortable to perform any operations on them.

Let’s say more: at the moment there are not even such areas of application of tablets in which a large computing power of the CPU is regularly required. Compilation, 3D modeling, rendering, archiving, professional photography and the like, which we usually test processors for PCs, on tablets, no one does. Yes, from time to time there is a need for computing power, for example, for indexing a new dictionary or a database of a potato program, but these are one-time needs and are almost always not critical to the speed of execution. At the same time, games for mobile devices are generally written in such a way as not to overstrain the processor, and when playing, the GPU is much more important (provided that the player can use hardware acceleration). Perhaps that is why Apple in its SoCs does not increase the number of CPU cores, as competitors do, but focuses on GPU performance. Ipad 4 is another proof of this.

To answer the question of how much GPU performance has increased, we used GLBenchmark 2.5.1, which simulates scenes from 3D games (Egypt HD and Egypt Classic). In the first table you will see the results of the iPad 3 and iPad 4, and in the second the results of the competitors. Recall that since the screen resolution of Android tablets differs from that of the iPad, it makes sense to look first of all at the graphs with the word Offscreen in them showing the performance when starting a game scene at a fixed resolution of 720p. As for the rest of the graphs, they show the performance at the maximum display resolution and therefore both iPads with a resolution of 2048×1536 find themselves in worse conditions than Android devices since 1280×800.

So, we see that PowerVR SGX 554MP4 (iPad 4) outperforms PowerVR SGX 543MP4 (iPad 3) by an average of 1.5 times. As for Android rivals, they don’t even reach the iPad 3 yet.

What does this mean in practice? First of all, iPad games can be more beautiful than Android tablets. True, the key word here can. And it is not at all a fact that they really will. First, most of the major publishers are now looking to create multi-platform projects. And they are unlikely to draw significantly more beautiful photographs for the iPad than for top-end Android tablets. Most likely, Android tablets will be the benchmark. Consequently, the potential of the iPad 4 GPU will remain (at least for the first time) undisclosed. Secondly, even if you look at the situation within the framework of one platform (iOS), it is unlikely that in the next year and a half, developers will create games that require the performance of iPad 4 and for which the performance of iPad 3 is not enough. Of course, in two years, when the iPad 5 and iPad 6 are released, the system requirements will be written: iPad 4 and newer. But that will be in a couple of years. And today, most likely, with all the desire, you will not be able to feel the difference in real applications between the iPad 3 and iPad 4, even despite the impressive difference in benchmarks.

Screen and software

Like the iPad 3, iPad 4 features a remarkable Retina display. Resolution 2048×1536 at the time of the release of iPad 4 was not surpassed by competitors, and in other respects, the iPad 4 screen is great. True, in mid-November, a 10-inch Google Nexus 10 tablet with a resolution of 2560×1600 (and a pixel density of 300 ppi) appeared on sale in some Western countries, which is more than that of the iPad 3 and 4. But we have not yet been able to evaluate the Nexus 10 screen (but we will definitely do it!).

As for the iPad 4, we didn’t notice any differences compared to the iPad 3 screen. Apparently, this is the same display. But this is good, because, we repeat, at the moment this is almost the best display in 10-inch tablets.

Here is a detailed examination of the Retina screen, carried out earlier by the editor of the Monitors and Projectors and TV sections Alexei Kudryavtsev.

With manual brightness control, its maximum value was 330 cd / m2² (iPad 2 has 280 cd / m2²), minimum 2.8 cd / m2² (25.2 cd / m2²). As a result, at maximum brightness in bright daylight, it will be possible to see something on the screen, and in complete darkness, the brightness can be lowered to a comfortable level. Automatic brightness control works in the style of Apple, which is thoughtlessly copied by other manufacturers (it does not apply to Samsung): in Auto mode, when the ambient light level increases, the brightness rises, but when the ambient light level is reduced, it remains unchanged, and we did not wait for a corresponding decrease in the screen brightness. However, if you put the tablet into sleep mode and turn it on again, the brightness will be set in accordance with the ambient light level. The minimum and maximum levels in Auto mode depend on the position of the brightness adjustment slider. So, when the slider is set to maximum, the automatic adjustment in bright light sets the brightness to a maximum of 330 cd / m2², in the dark at 300 cd / m2² (which is a lot). If the slider is located approximately in the middle, then in bright light it will be about 250 cd / m2² (optimal), in the dark 4.5 (which, of course, is too little). In general, the creators of the iPad need to discard their dogmas, allow the brightness not only to increase, but also to decrease automatically, and at the same time, to bring the matter to the end, let the user himself and explicitly set the limits of automatic brightness adjustment. The brightness control is apparently carried out by adjusting the voltage on the backlight LEDs. Most likely, it was not without pulse-width modulation (with its help it is more economical to regulate the voltage), but it has a high frequency and there is a smoothing filter in front of the LEDs. As a result, the backlight, regardless of its intensity, has a barely pronounced modulation with a frequency of slightly less than 16 kHz. For example, this is how a photographer looks like the brightness versus time in a 2 ms window (brightness in arbitrary units along the vertical axis):

Most manufacturers in their devices with LED backlight (tablets, laptops, monitors) adjust the brightness using pulse width modulation (PWM) with a change in amplitude from 0 to 100% rectangular pulses. And although the negative effect of PWM backlighting with a sufficiently high frequency (from 180 Hz and above) still needs to be confirmed, Apple still needs to be given credit for its devices (at least, those who have visited us on testing iMac, Apple LED Cinema Display, Apple Thunderbolt Display, MacBook Air and iPad), the backlight does not flicker. The old iPad also lacks PWM brightness, and automatic brightness adjustment works in much the same way.

The New iPad uses an IPS-type matrix, so the screen has very good viewing angles without inverting shades and without significant color shift, even with large gaze deviations from the perpendicular to the screen. True, which is typical for any IPS matrix, the black field is lightened when deviated diagonally: the left corners (when the Home button is oriented downward) remain close to neutral gray when deviated to the right, but the right corners when deviated to the left acquire a pronounced purple tint. With a perpendicular view, the uniformity of the black field, with the exception of a couple of local areas on the border of the screen, is good (the first i Pads also have an IPS matrix, but with a more pronounced purple tint when the gaze deviates to the corners). Black-white-black response time is 14.4 ms (7.8 ms on 6.6 ms off). The transition between 25% and 75% halftones (by numerical color value) takes 25.1 ms in total. The matrix is ​​significantly faster than typical IPS solutions used in tablets (we did not measure the response time of the first two iPads.) For the 32-point gamma curve, the exponent of the approximating power function turned out to be 2.19, which corresponds to the standard value in 2.2, while the real gamma curve practically coincides with the power dependence.

The first two iPads have a similarly good gamma curve.

The contrast is quite high at 830: 1 (the old 740: 1). The color gamut is exactly sRGB:

The iPad 2 is getting worse: like the vast majority of tablet IPS screens, the color gamut is noticeably narrower than sRGB:

The Sony Tablet P is also close to sRGB coverage, but perhaps this dual-screen tablet uses VA matrices, and not IPS, as we suggested in the article. While this question remains open.

The spectra of the new iPad confirm what was said about color gamut:

For comparison, the screen spectra of iPad 1 and 2:

It can be seen that in old iPads, the matrix light filters mix the components together. This technique allows you to increase the brightness of the screen with the same energy consumption for the backlight. In the new iPad, blending is exactly what should result in standard coverage.

Color temperature balance good shades of gray have a color temperature of about 7000 K, but the deviation from the blackbody spectrum (delta E) is relatively large (due to some excess of the green component), although below 10, which is considered acceptable for a non-professional device.

The screen of iPad 1 and 2 is at least somewhat better than the new one, albeit in small details: the color temperature is a little closer to the standard 6500 K, the delta E changes less and less when going from white to shades of gray.

In total, the screen of The New iPad is distinguished not only by its high resolution, but also by excellent color reproduction, in particular, by an almost ideal gamma curve and standard color gamut. As a result, the photos on this tablet will look exactly as they should be displayed on a consumer device. Those who are paranoid about PWM in the backlight will be glad that in this device Apple has not changed its tradition, the backlight flicker is not detected even by a hardware test. Well, with the peculiarity of the algorithm for automatically adjusting the brightness of the screen, the owners of this gadget will have to put up with it, or, even easier and more pleasant, convince themselves that this is how everything should work 🙂

Exact screen dimensions: 24.6 cm (9.68 inches) diagonal, 19.8 cm wide, 14.9 cm narrow.

In terms of software, the iPad 4 is also nothing new. Except for the fact that the iPad 4 comes with iOS 6 preinstalled, whereas the previous model ships out of the factories with iOS 5. But it can be upgraded to iOS 6.

Review and testing Apple iPad 4

Let’s start with the terminology. Apple hasn’t given the new iPad its original name. It’s just iPad (with Retina display). Unofficially, it was called the iPad 4, since it is the fourth generation of the iPad. However, as we remember, the previous generation also did not have a number in the name. At the presentation, it was called The New iPad, and although later information appeared that The New iPad is not a proper name, but just a new iPad, the third generation of Apple tablets began to be called that way.

Now, the company’s marketers have completely confused buyers and the press. Calling the new iPad of the previous generation is somehow strange, and most importantly it is not clear how to call the fourth generation iPad. Without the previous The New iPad, one could call new every next generation. But over the past months, the word new has become very stuck to the iPad of the third generation.

Why this leapfrog? Why was it impossible to leave the numbering, as is the case with the iPhone? Apparently, Apple’s marketers decided to follow the same path as with laptops. As we know, MacBook Pro and MacBook Air also do not have numbers, and generations are designated by phrases like Late 2011 or Mid 2012. Well, let’s see how this affects sales. For the sake of simplicity and to avoid confusion, in the article we will still call our new product iPad 4, and the previous model iPad 3.

So let’s take a look at the specs of the iPad 4 versus the iPad 3 and major competitors.

According to the manufacturer’s information; in the case of iPad, the weight of models without a cellular module is indicated; in the case of Infinity, the weight is indicated for a tablet without a docking station.
For all tablets, the price is indicated for a configuration with 64 GB of flash memory and without a cellular module (if possible); 4th generation iPad is US official price (excluding state tax), 3 other tablets are average price, while ASUS price is based on docking station.

As for the characteristics, then, as we can see, the changes compared to the iPad 3 relate exclusively to the internal components: a new SoC, a new front camera. But a comparison with competitors is hardly possible based on this table alone. At least, there are no such characteristics on which the iPad 3 would be inferior to competitors, and the iPad 4 would surpass them, so it is difficult to draw any preliminary conclusions here. Let’s instead move on to face-to-face introduction and testing.

Camera

The rear camera in iPad 4 is identical in resolution and aperture to the third generation iPad: 5MP and f / 2.4. The front camera on the iPad 4, on the other hand, has a resolution of 1.2 megapixels, which is higher than that of the iPad 3. In addition, the front camera supports 720p for FaceTime calls. Overall, the iPad 4 is identical to the iPad mini in terms of cameras. This, of course, is very strange, since the iPad 4 is a top device, and one could expect from it the same camera as the iPhone 5. On the other hand, hardly anyone would use a 10-inch tablet for shooting often, but for occasional shooting, the rear camera is very good.

Let’s start with a 100% fragment of a shot from a building window on a cloudy day. Hereinafter, there will be a frame of the iPad 4 on top, below the iPad 3.

As you can see, the pictures are almost indistinguishable, the only slight difference is in the white balance. Recall that almost all shooting parameters (including white balance) are set automatically by the cameras of iOS devices, and the user does not have the ability to manually adjust them.

Next pair of night shots.

Here, too, the results are very similar in terms of the picture and the same shooting parameters, both tablets set ISO 800 and shutter speed 1/15 s. But the result, oddly enough, the iPad 3 turned out even slightly better (the noise is more noticeable, but there are more details).

The last test, capturing text, both devices passed without problems.

This test shot leaves no doubt that the slight difference in the picture is due to the differently set white balance, and not due to shooting conditions (which might have changed slightly over the time between shots). It’s a shame that you can’t adjust the white balance of the iPad camera, but the color distortion is by no means catastrophic.

In terms of shooting, we still have no complaints about the iPad. The rear cameras of both tablets shoot in Full HD, with very good clarity and color reproduction. But here’s what’s interesting: the iPad 3 has a higher bitrate! Examples: iPad 4 (66.7 MB, 31 seconds), iPad 3 (77.9 MB, 30 seconds).

In general, the iPad 4 camera left a good impression, but it is embarrassing that the cameras in the Apple tablets of the 3rd and 4th generations, while the known characteristics are identical, still behave slightly differently. In particular, with iPad 4 the bitrate is lower, and the color rendition when shooting is slightly different.

Packaging and equipment

The packaging of the iPad 4 is practically the same as the packaging of the tablet of the previous generation.

As for the package bundle, everything is predictable here too (the set of plugs for charging depends on the region in which the device was purchased, so you shouldn’t pay attention to this). The only difference is the Lightning cable instead of the traditional one. As you can see, not only the iPhone and iPad mini, but also the adult iPad got a new connector.

Autonomous work

Ipads have always had very decent battery life. Ipad 4 is no exception. Over, with maximum GPU load and maximum screen brightness, it will work even longer than the iPad 3 was shown by GLBenchmark 2.5.1. An Egypt HD scene fired at 60 fps, the iPad 4 was able to play at 100% screen brightness for 5 hours. The iPad 3 did worse for about 4 hours. From which we can conclude that the new SoC is not only more efficient, but also more energy efficient.

With other uses, the duration of the iPad 4 battery life has not changed compared to the iPad 3: about 10 hours when reading or quiet (without too frequent page refresh and downloading heavy content) web surfing via Wi-Fi, about 5, 5 hours of online playback via browser. The identity of the results is clear: the battery is the same here (Apple traditionally does not report its capacity, however, such a conclusion can be made from the data provided by the company on the operating time), the screen is also, therefore, during normal use, which does not imply an increased load on the SoC, there can be no difference.

Review of the Apple iPad Mini 4 tablet

The original review in German can be read here.

The media talked a lot about the new iPhone and iPad Pro. The Mini has received undeservedly little attention. Nevertheless, it was she who was the first of all new products to hit the market.

There are few visual changes relative to the past Mini. The colors remain the same: dark silver, or Space Gray, shiny silver (Silver) and gold (Gold). The built-in memory can be 16, 64 or 128 GB, each model has two editions. With or without mobile LTE support. The youngest model, with 16 GB of memory and Wi-Fi, starts at 389 euros. At the current exchange rate, this is about 29 thousand rubles.

Ports and communications

On the front side, on the button at the bottom of the screen, there is a Touch ID fingerprint scanner. It is designed to save the user from constantly entering a password to access their device. In addition, our LTE model is equipped with the usual slot for carrier nano-SIM cards. Which, in spite of everything, are still difficult to find in the offices of mobile operators (most of them suggest cutting the micro-SIM yourself).

On the bottom you can find a port for charging and transferring Lightning data, on top there is an audio output for headphones or a 3.5 mm headset.

Wireless capabilities include Wi-Fi 802.11ac, Bluetooth, 3G / LTE (up to 150 Mbps) and a gorgeous satellite navigation module that works even in multi-story buildings.

Design, features and workmanship

In this review, we will focus on the gold model we got. She weighs everything 304 grams, less than any predecessors. The thickness relative to the Mini 3 has also been reduced, albeit slightly. Miniature, but still comfortable sizes. The main advantage of the Mini 4 against the Air 2.

The build quality itself has remained the same or has been slightly improved. The case resists moderate pressure and abrasion very well, but falling onto a hard surface, even from a small height, is likely to crack the screen’s protective coating. When the tablet is shaken strongly, there is no loose or loose parts inside. On the contrary, all the details are placed extremely tightly. A significant part of the internal space is occupied by a non-removable battery.

The gold version looks a little more interesting than the silver and gray. It should be noted, however, that in the dark, a light frame can distract from watching a movie or reading a book. Otherwise, there are no complaints and cannot be: in the end, design was and remains the strong point of apple products.

Ios 9: In the footsteps of the competition

Iphone 6s and 6s Plus, iPad Mini 4, and iPad Pro ship with iOS 9. Users of older devices can upgrade to it on their own. The list of compatible models even includes the iPhone 4s, already a very middle-aged phone with 512 MB of RAM.

So what has changed regarding iOS 8.4.1? Actually, not much. The changes fit the description of evolutionary, but certainly not revolutionary. Added new multitasking capabilities that don’t really add much convenience to an entertainment-centric operating system, and have been available in Android devices from Samsung and LG for quite some time. The animation of some regularly performed actions has been changed, in particular, the call of the screen of recent applications.

If you do not go into details, the user will not notice the actual benefit from switching to iOS 9, only a slight drop in overall performance (as opposed to Apple’s announcement of its increase), as well as a slight “culture shock” from dubious visual innovations. There are also some, not too serious, flaws. The author of these lines noticed problems in the work of Safari with some RTMP streams and the inability to clear the list of recent applications (everything is restored after a restart, which in many cases is undesirable). One way or another, the update to iOS 9.1 may come out in the first half of October. Or maybe not come out.
