Snapdragon 801 installed in SoC
As mentioned at the beginning, the Xperia Tablet Z, which is equivalent to the previous model, was announced on February 26, 2013 (shipping from April 13). It will be a model change in about one year. The previous model is 10.1 type full HD with a thickness of less than 7 mm, and although there are many common parts such as a light and thin housing weighing less than 500 g, the installed interface, etc., the SoC that is the heart is Qualcomm Snapdragon S4 Pro (1.5 GHz / quad core) , Krait / Adreno 320).
On the other hand, the Xperia Z2 Tablet uses a quad-core Snapdragon 801 at 2.3GHz, a SoC that is two generations different. It consists of Krait 400 (2.3GHz) and Adreno 330 (550MHz), and the memory is LPDDR3-1866 (14.9GB / sec), which greatly improves the performance.
By the way, the Snapdragon 800 one generation ago has the same maximum CPU clock as 2.3GHz, but the Adreno 330 is 450MHz, which is 100MHz lower, and the memory is LPDDR3-1600, which is 12.8GB / sec, which is a narrow band.
With this difference, the performance is likely to be quite different. The main specifications are as follows.

The installed memory is 3GB and the storage is 16GB. The 16GB model will be sold exclusively at the Sony store. 3GB of memory on an Android tablet is one of the largest at the moment. It also supports microSD cards as external media. Although the storage is small, there should be no problem because a microSD card can be used.
The OS is Android 4.4 and the latest version. It is a version that supports multi-users and restricted users. For example, you can create an account for the whole family and share it in the living room, or you can restrict apps and content and share it with children. This feature is currently not compatible with iOS, so it will be an advantage for Android.
Interfaces are IEEE 802.11ac / a / b / g / n, Bluetooth 4.0, Micro USB (MHL 3.0 compatible), microSD card slot, NFC, 2 million pixel front camera / 8.1 million pixel rear camera, audio output, speaker, GPS ..
The display is equipped with the company's triluminous display for mobile, which is 10.1-inch and has the features of high resolution / high brightness / wide color gamut liquid crystal. The resolution is WUXGA's 1,920 x 1,200 dots. Since Micro USB is compatible with MHL, you can use the MHL to HDMI cable to connect to a home LCD TV, etc., and enjoy it on a large screen.
The size is about 266 x 172 x 6.4 mm (width x depth x height) and the weight is about 426 g, which is 0.5 mm thinner and 69 g lighter than the previous model Xperia Tablet Z. It also supports waterproof performance IPX5 / 8 (previous model is IPX5 / 7) and dustproof performance IP5X. The battery is equipped with 6,000 mAh.
There are two color variations, black and white. The storage 16GB model is limited to direct sales and costs 51,000 yen (excluding tax).
Front. The front camera is on the top center, and the back of the speaker is on the bottom left and right dents. The rear camera is on the upper right, and the NFC mark is on the lower right. Headphone terminal and dock terminal on the lower side. There is nothing on the right side and the upper left side. Micro USB and microSD card slots on the top side, under the cover. A USB AC adapter with a power button and audio ± button on the left side. Approximately 53 x 40 x 20 mm (same as above) / 39 g, which is a fairly compact weight actually measured 425 g (iPad Air is 475 g) Comparison with iPad Air / footprint. The depth is almost the same, and the width is compared / thickness with the iPad Air, which is longer for the Xperia Z2 Tablet. An optional Bluetooth speaker dock and AC adapter that feels as thick as the silver frame around the iPad Air. The actual measurement is 281g, which is surprisingly light. Power button, phone button, volume ± in the foreground, dock connector in the dent, power input and voice input in the back, NFC for pairing on the topPersonally, when I first touched the iPad Air, I didn't think it was so light or thin, but the Xperia Z2 Tablet is thin and light anyway. Although the difference in numbers is several mm / several tens of grams, it is strange to human senses. As you can see from the comparative photos posted, the footprints are almost the same depth and wider (screen aspect ratios are 4: 3 and 16: 9).
The front is the front camera on the center. Since the speakers are embedded in the dents on the lower left and right, the sound comes out in front. The back is facing the rear camera on the upper right, and the NFC mark is slightly below it. On the left side, there is a power button and a voice ± button on the left side. There is nothing on the right side.
On the top side, under the cover is a Micro USB and microSD card slot. When charging from USB, it is quite troublesome to open this cover, but it is unavoidable because it is for waterproof performance IPX5 / 8 and dustproof performance IP5X. There is a headphone terminal and a dock terminal on the lower side. The thickness is 6.4mm, so it feels like all the connectors are just barely fit.
The included USB AC adapter is approximately 53 x 40 x 20 mm (same as above) / 39 g, which is quite compact. Of course, it can be charged using the same type of AC adapter. However, it takes a long time to fully charge from 0% remaining capacity (4 hours or more).
The actual weight is 425g. The iPad Air weighs 475g, so the difference is 50g. Please refer to the photos posted for the difference in size and thickness, but you can see that the Xperia Z2 Tablet is definitely one level lighter.
The 10.1-inch triluminous display for mobile with 1,920 x 1,200 dots is said to be a stone's throw. No complaints about brightness, contrast, color development, and viewing angle. The touch response is also good. In particular, the saturation of the primary colors is high, and not only photos but also videos look good.
Of course, there is no vibration or noise, but the heat generation is within the range that is not noticeable in the trial range. The sound is of high quality, but a little lack of power. I would like to use it together with the optional Bluetooth speaker dock.
This Bluetooth speaker dock "BSX10" is paired with the main unit using NFC, making it easy to handle. Although it is lighter than it looks at 281g, the Xperia Z2 Tablet itself is super lightweight, so it can be installed stably. It doubles as a charger and has a separate voice input. The actual selling price is around 15,000 yen (excluding tax).
Other options include a cover with a stand "BKC50" equipped with a Bluetooth keyboard, a Bluetooth remote control "BRH10", and a booklet-like protective cover "SCR12" with a stand function.
The rear camera is equipped with an "Exmor RS for mobile" with approximately 8.1 million pixels, and the front camera is equipped with an "Exmor R for mobile" with approximately 2.2 million pixels.
I posted one sample each taken in a bright place and a dark place using the rear camera. It was a fully automatic shooting without any exposure compensation or white balance adjustment. AF can be adjusted to the desired position with a touch quite quickly.
A bright place. Focal length 3mm, 1,746 x 3,104 pixels, F2.4, 1/500 sec, ISO40 Dark place. Focal length 3mm, 1,746 x 3,104 pixels, F2.4, 1/16 sec, ISO400As you can see, is it the same level of image as today's high-end smartphones? However, since the housing is large, it is easy to shake, and the shadow of the main body may be reflected in the picture. This is a matter of familiarity, but personally I thought it would be easier to shoot with a smartphone and handle the data via the cloud.
