The company a few days ago Apple officially unveiled the iPad Air 2, and so there was finally able to check how the new trinket from Cupertino compare to the competition. Just before the new iPad, Google revealed the Nexus 9 processor-based NVIDIA Tegra K1. This system is reflected in the market noticeably more echo than some had expected. The emergence of this structure in the new Nexus may be a harbinger of the market success of the new Tegra. The statement dorzucony is Samsung, so the largest supplier of mobile devices. Although the Galaxy Note 4 is classified more as a phablet, but probably worth it to throw in, at least to add a little spice compared.
The three of them, so the iPad Air 2 Nexus Galaxy Note 9 and 4, the device housings made of metal. Apple sticks to tradition, so the iPad Air 2 here is the only device with a single aluminum housing. Nexus 9 but has side frame made of brushed aluminum. Product Samsung breaks with the tradition of the South Korean company and we have aluminum instead of plastic frame. In terms of the materials used all three devices offer a level of high quality, although the iPad Air 2 in some respects leans forward.
Galaxy Note 4 has dimensions of 153.5 x 78.6 x 8.5 millimeters and is the smallest of the three, but it’s no surprise, since the device has the smallest screen. It turns out that iPad Air 2 is slightly larger than the dimensions of the Nexus devices 9 are respectively 240 x 169.5 x 6.1 millimeters and 228 x 153.68 x 7.95 millimeters. In terms of the thickness of the iPad 2 wins Air Nexus, and even with the smaller Galaxy Note 4.
The compared designs are based on the powerful hardware. Galaxy Note 4 exists in versions with Qualcomm Snapdragon 805 or Samsung Exynos 5433, Nexus 5 is the first tablet based on Tegra system K1 (Project Denver), and the iPad 2 as the first Air uses an Apple A8X. Google Nexus 9 at the moment seems to be the most powerful tablet on the market. Its focal point is the NVIDIA Tegra K1, accompanied by a RAM of 2GB.
Google Nexus 9 – unveiled a new tablet
Tegra K1 is the first implementation of proprietary architecture ARMv8 – performed NVIDIA. This system is equipped with two powerful cores CPU, making better use of the surface of the silicon core, but also to provide good energy efficiency. NVIDIA therefore does not intend to pursue most of the competitors who passionately add more cores, the amount of which is to attract consumers. Returning to the Tegra K1, the system operates at up to 2.3 GHz and has an integrated graphics processor DX1, based on the Kepler architecture and features 192 shader processors. NVIDIA has long been praised by the fact that DX1 has enough computing power to the mobile device to provide 3D graphics in this class that so far found only in desktop personal computers and game consoles. The first performance tests clearly show that the NVIDIA Tegra K1 is a powerful design.
Galaxy Note 4 processor Samsung Exynos 5433 stands out in terms of performance, from the latest smartphones from Apple (iPhone 6 and iPhone 6 Plus), no and above all from the Nexus 9 with Tegra K1, although the market still maintains a very high position. Samsung recently refreshed its system by introducing it to offer the new name – Exynos 7 Octa. It is manufactured in 20-nanometer lithography and has a total of eight CPU cores – four energy-efficient Cortex-A53 and Cortex-A57 four to more complex tasks. The load of each core is continuously adjustable, depending on the degree of their load. It is worth noting that the Galaxy Note 4 has 3 GB of RAM.
Apple iPad 2 while the Air is Apple’s proprietary processor A8X, which is a new version already used in smartphone iPhone 6 and iPhone 6 plus the A8, which was the second generation 64-bit SoC Apple. Compared to its predecessor, so the A7 processor for tablet iPad Air, the new A8X provide is about 40% better performance CPU and a 2.5-fold increase in graphics performance. If data from Apple are confirmed in tests, it A8X can ultimately achieve levels of performance close to the Tegra K1. A8X processor in the iPad 2 accompanying Air RAM 1 GB, and the motion coprocessor Apple M8. The new iPad is, therefore, the least RAM, in combination with the new Nexus Galaxy Note 9 and 4 must be borne in mind that Apple devices generally have less RAM than competing alternatives. Apparently the optimizations made in the software make it 1 GB of RAM in the iPad 2 by Apple Air completely should be sufficient.
Air iPad 2, iPad 3 mini, Mac and OS X Yosemite – conference Apple
Apple in terms of call display, touch panel and glass cover one took another step forward. It affects not only the thickness of the entire device, but according to Apple provides a better picture quality, including by minimizing the transfer of light between pixels, which is to improve focus, as well as by increasing the light transmission for superior brightness. As far as the resolution is Air iPad 2 has 2048 x 1536 pixels, which gives a density at 264 pixels per inch. Air iPad 2 has a special anti-glare glass surface finish. The degree of reflection of light is supposed to be reduced by up to 56%.
Google Nexus 9 has the same screen resolution as the iPad Air 2, so 2048 x 1536 pixels. It features while większee density of pixels, and this is due to the fact that the Nexus 9 has a screen size of 8.9 inches, and the new iPad Air 9.7 inches. It should be noted that in both cases, manufacturers have used arrays IPS (In-Plane Switching). Galaxy Note 4 but has a Super AMOLED type screen with a diagonal of 5.7 inches and a resolution of 2560 x 1440 pixels. AMOLED display with the rules is characterized by greater energy efficiency, but the specific implementation depends on how deal will odzworowaniem colors. This type of screen is typically characterized by better contrast.
Air iPad 2 and Nexus 9 have digital cameras with similar specifications. In both cases a module with a resolution of 8 megapixels and aperture of f / 2.4. Both devices can record video in 1080p at a frequency of 30 frames per second. Air iPad 2 is true there is no LED lamp, but on the other hand, this model offers several other features such as Time Lapse, Slo-Mo and image stabilization. These are not the only functions of copyright, because the camera Nexus 9 also has some “extras”. As for the front webcams, this iPad Air 2 in specification of the Nexus loses ninth first tablet has a resolution of 1.2 megapixels, while in the second case we have resolution of 1.6 megapixels. Samsung Galaxy Note 4 is phablet, and this type of device manufacturers pay more attention to digital cameras. Therefore, in this category, Galaxy Nexus Note 4 and the iPad left behind, because in his case we have a digital camera with a resolution of 16 megapixels (of 3 megapixels more than the Galaxy Note 3). It is worth noting also optical image stabilization. Even the front webcam Note 4 compares to competitors great. We have a module with a resolution of 3.7 megapixels and aperture of f / 1.9, which should be enough for this to catch sufficiently large amount of light. The front module even has the function of panoramic images, making it possible to create a very impressive image of “selfie” especially group.
With the introduction of the Nexus 9, Google has set the appearance of the operating system Android 5.0 “Lollipop” which until now has been known as “Android L” and now has to be one of the biggest steps forward in the history of the Android platform. First of all, the new system there is a new style user interface, called Material Design. With it, Google introduced not only better graphics, the greater the possibility of use (eg through voice commands), as well as improved multitasking. In addition to the Android 5.0 with Material Design will be Google’s first attempt on the way to bond a variety of devices under a single software platform. To this end, the new Android improved eg. Features for sharing media files between different devices.
With iOS 8 Apple first opened its own platform for improvements, such as even from other developers on-screen keyboard . In addition, iOS 8 introduces, inter alia, Health Kit, which is responsible for the storage of medical data for use in an emergency. In the new release, Apple has improved the solutions to facilitate handling equipment. Siri, now also integrated with Shazam, can tell us, what song is currently playing music. Added a new gestures for e-mail and other system components.
Samsung Galaxy Note 4 – we know the Polish price
Galaxy Note 4 is based on the Google Android operating system” KitKat “with an original Samsung TouchWiz overlay. Interface Samsung adds “KitKat”, among others, the possibility to change the size of the application on the screen, and run several applications in the windows. TouchWiz has long been the part of users is criticized, but either way, it provides at least a pair of unique solutions Galaxy Note 4.
The Air iPad 2 and Nexus 9 are products with high segment. Even if the market price will differ, each of these tablets have to offer something unique, something new and at the same time well-known to people familiar with the platforms on which they are based. It all depends on the preferences of potential buyers. Air iPad 2 can boast excellent functionality and performance, as well as a neat performance. Nexus 9 while its strengths are primarily in the performance of the GPU, through which the device should cope well with the latest games. Both devices are ultimately very versatile and allow you to do the same, but different programming basics, user interfaces of the systems themselves and often the application. But keep in mind that tablets are still lagging behind smartphones and phabletami, at least when it comes to digital cameras, although it would seem that the fact of the dimensions should be the opposite. In our statement of Galaxy Note 4 can not shine against the other two in many respects, but where there is digital photography does not give the rest a chance.
