The Loudspeakers Both are located on the right side of the housing. Why Cube has opted for such an unusual design remains questionable. Especially with stereo sound, a separate placement would have been desirable.

The control buttons are one Power, One Volume rocker and Reset button, All keys sit firmly and without play in the rack. A longer press on the reset button also resets the BIOS to factory settings.

The Cube i7 Book impresses with its crisp and clear presentation, rich colors and a rich black value. Even at an extreme viewing angle, the color fastness is retained and details are very easy to read. The brightness of the display is convincing when used at night, but also when working with direct light.

The touch screen forms FocalTech FT5826 IC Controller with Wacom Stylus Support. Inputs are recognized very accurately, which is why the tablet is also suitable for artistic applications. Multitouch is supported with a maximum of 10 fingers.



Inside the Cube i7 Book slumbers faster Intel Skylake M3-6Y30 processorin the 14nm procedure will be produced. This dual core processor has been released in 3. Quarter 2015. The basic clock frequency is 900MHz. Turbo Mode the processor reaches a maximum clock frequency of 2.20GHz.


The GPU is one Intel HD515 processor graphics with maximum 850MHz clock rate. DirectX 12 and OpenGL 4.4 are supported. Even 4K video playback with 60Hz are no problem for the Intel HD515 processor graphics.

In the test could 4K video streams rendered without loss and transmitted. Also graphically more challenging games can be played on the tablet. An example would be Dota 2that is playable with a resolution of 1920x1080 pixels and medium graphics settings with a pleasant 25-30 frames per second. Another example would be Battlefield 3which can be played with reduced resolution and low graphics settings with almost no image break.

User Interface

Regardless of whether you use the device for surfing the net, for video streaming, for data transfer or for gaming, the Cube i7 Book does above average in every respect due to the powerful processor and cannot be compared with much weaker Intel Atom tablets.


A large Point of criticism is the maximum temperature of the processor and the heat released to the outside. Under full load, the tablet reaches after only a short time Maximum temperatures of 97 ° C on the processor cores and a noticeable Outdoor heat of about 40 ° C on the back of the case. Unfortunately, Cube did not install a decent cooling solution, so the tablet chipset emits its waste heat directly to the aluminum housing.

If the high temperatures are a thorn in the side, you can install your own cooling solution on the tablet chipset with a little manual skill. Instructions can be found on YouTube.


The cameras of the Cube i7 Book are not worth mentioning. On the back is a 5 megapixel camera with autofocus, The shot in the test Recordings are mostly noisy and out of focus, which is why you should rather grab for snapshots to the smartphone camera. The front camera resolves with 2 megapixels and is only suitable for video telephony. Selfie lovers should also use a high-quality smartphone camera.

Overall, the sound lacks volume, which makes it sound downright flat. Sounds are transmitted without interference via the headphone connection. The maximum volume is also impressive.


The battery offers a Capacity of 4.300mAh, At the expense of more performance, the battery life is comparatively low. With normal use one reaches Terms of about 5 hours, A very low value when compared to Intel Atom tablets, which often achieve twice the battery life.

The tablet can be charged via the 12V DC input, as well as over the USB type-C connection, The charging time is about 3 hours with the included charger. Charging times of just under 2 hours are possible with a USB fast charger.

Cube i7 Book Accessories

The Cube i7 Book is without keyboard and without stylus, These accessories must be purchased separately, which means Additional costs of about 80 € arise.

The Keyboard is only with English-language layout available. This is connected via the pin connector on the bottom of the tablet. With the keyboard connected, the Cube i7 Book can be used like a small notebook. All the necessary buttons are available and one too multifunctional touchpad with gesture recognition is available. The design of the keyboard is adapted to the design of the tablet. On the left and right side of the keyboard are each a USB 2.0 jack. The processing of the keyboard could be better, but is still in the price range. The keys have a pleasant pressure point. The touchpad, on the other hand, floats a bit in the case.

The touch screen is Wacom stylus compatible. Precise drawings or typing are due to the existing "Palm Rejection" no problem.
