iPad mini got a display Retina, and Kindle HDX from Amazon – a new competitor in the market.
New iPad Air, presented last week, still encased in a thinner, lighter design, has a 64-bit processor and two dual-band antenna MIMO Wi-Fi. And yet, the more impressive the new iPad mini, repeating many of the characteristics iPad Air, including the number of pixels, but in a form factor 7.9-inch tablet. He will certainly have an impact on the market, and especially the sales of Kindle Fire HDX – the latest addition to Amazon.
few tablets of this class can match the impressive features on-screen bar HDX, but new mini approached them closely and the ability of Apple to charm buyers, no one doubts.
So, compare the latest small plates of two companies: a 8.9-inch Kindle Fire HDX Amazon and the new iPad mini Apple.
CPU and graphics
iPad mini (like the iPad Air) is built on the company’s 64-bit single-chip system, Apple A7, first introduced in the iPhone 5S in the past month. This SoC is located on 102-mm chip includes two 64-bit kernel ARMv8 (more than a billion transistors!) For application workload and uses a modern set of commands. Processor clock speed A7 – 1,3 GHz. There is also a dedicated coprocessor physical movement M7 (motion processor), which continuously processes data from the accelerometer, gyro and compass (it provides an interface to the new API CoreMotion). According to some reports, SoC A7 also includes a dual-core GPU PowerVR G6430 in chetyrehklasternoy configuration (made by Imagination Technologies, which calls him “the best scalable cluster computing architecture»).
Amazon does not have a clustered SoC, but the Kindle Fire HDX uses an impressive quad-core Qualcomm Snapdragon processor 800 with a clock speed of 2.2 GHz. It includes four core Krait 400, similar to ARM Cortex-A15, and Adreno 330 graphics processor, which, as stated by the manufacturer, 50% faster than the previous version of the Adreno 320.
RAM and storage
Apple does not disclose the size of the RAM in their devices, and so far no one has expressed any guesswork. CRN Test Center believes that the mini-iPad has at least the same 1 GB as the iPhone 5S, since he, too, will have to deal with 64-bit applications. Amazon says its Fire HDX has 2 GB of RAM to run applications in the original Fire OS 3.0 (which itself runs on top of Android 4.2.2). For data storage Apple has added a 128-GB model to the previous versions of 16, 32 and 64 GB. Kindle Fire HDX offers a choice of 16, 32 and 64 GB.
screen
newest mini-iPad has the same number of pixels of the screen, and that’s a big iPad. Its 7.9-inch display Retina – it’s IPS-panel with a resolution of 2048 x 1536 pixels, which gives a density of 326 per inch ppi. 8.9-inch LCD-screen tablet Kindle Fire HDX has a resolution of 2560 x 1600 pixels, or 339 ppi. With such a high resolution the human eye is unable to distinguish individual points, both visually and clean the screen are the same. Both affect the clarity and realism of the image.
Size and Weight
new iPad mini is 20.1 cm long, 13.5 cm wide and 7.4 mm thick . Kindle Fire HDX little more: 23.1 inches long and 15.7 inches wide. In other words, the Amazon tablet is an inch longer and an inch wider than the Apple. The thickness is almost the same: 7.9 mm, a thickness of 0.5 mm mini-iPad. iPad mini with Wi-Fi and LTE weighs 340 Kindle Fire HDX with the same communication capabilities weighs more than 43 grams – 383 g
cameras and communication
Apple has remained the same Camera: 1.2-megapixel front-facing fixed focus – is about the same as the Kindle, -, and 5-megapixel main rear with a relative aperture of 2,4 f and pyatilinzovym lens with autofocus. The main camera at Amazon – 8-megapixel lens with the aperture 2,2 f, LED flash and image stabilization. The rear camera both tablets can shoot video with a resolution of 1080p, while the front – 720p (both). You can also use Apple geopositioning tags for photos and video footage.
Both tablets have two antenna MIMO Wi-Fi (dual-band), Bluetooth 4.0, and (as an option) LTE from AT & T or Verizon. Apple adds to that Sprint and T-Mobile. Kindle supports Miracast specification for wireless video streaming on Wi-Fi; Apple uses its own protocol. Short-range radio communication (NFC) is not supported neither there nor there.
Rates and Availability
Prices of iPad mini – from $ 399 with 16 GB of storage and only Wi-Fi, and U.S. $ 529 with Wi-Fi and LTE. Deliveries are scheduled for the end of November.
Kindle Fire HDX starts at 379 dollars with a 16 GB drive and only Wi-Fi, and U.S. $ 479 with Wi-Fi and LTE (add to that the $ 15, to remove the ads from the lock screen). Amazon is taking pre-orders, with deliveries to begin Nov. 7 models with Wi-Fi, and on December 10 – with cellular communication.
