Asus Transformer Book T102HA (x5-Z8350, 4 GB, 128 GB) Convertible Review

Nino Ricchizzi, 👁 Sebastian Jentsch, Felicitas Krohn (translated by Katherine Bodner), 01/24/2018

A straightforward concept. The requirements for a convertible that functions as your daily companion are high. Apart from a fully functioning Windows operating system, performance and battery runtimes need to be good too. A bright display and solid build should also be included - and all this, ideally for a good price. Asus has a solution to offer: The Transformer Book.

Small, handy and a Windows operating system: If you have these requirements you will probably come across the Asus Transformer Book T102HA. The Windows tablet is only about 10 inches large and is equipped with an Intel Atom processor, 4 GB of RAM and 128 GB of storage. The price of our small test unit is around $370.

Lenovo's competitor is in the same price range: The IdeaPad Miix 320 Pro uses similar components, but has a higher display resolution. The Acer Switch One 10 turns out to be significantly cheaper, but the specifications of this affordable alternative are not quite as good: It offers only 2 GB of RAM and 64 GB of eMMC storage.

Case & Connectivity

The style of the Asus Transformer Book reminds us of the well-known Microsoft Surface series. The case has a rough metal surface and the device comes with a keyboard that can be docked on and has a fabric cover. Due to its build design, the convertible can only be used with a stand. Neither the keyboard nor the tablet have hinges. The stand flips out from the back of the tablet, but is a little difficult to open. The two competitors use different techniques and can therefore be used on your lap, thanks to a stable docking connection.

A particularity of the Transformer Book is its fingerprint sensor on the back. This responded reliably and quickly during testing.

Peripheral devices can be connected via the ports on the left side of the device. The manufacturer has made use of a Micro-USB port, which is used as power supply, and a standard USB Type-A port (USB 3.0). Unfortunately, it does not include a USB Type-C port. You need a Micro-HDMI cable to connect to an external screen.

Wireless communication is taken over by the Qualcomm-QCA9377 module. This is supposed to reach gross rates of up to 433 Mbit/s and has Bluetooth 4.1. Our test unit reached an average transfer rate of 308 Mbit/s (5 GHz) as a client in our Wi-Fi test. The average drops to 235 Mbit/s when working as a server. 

We have nothing to complain about the workmanship on this small convertible. The only thing we noticed is that the tablet does give in to pressure slightly at the back, but this is not a problem.

Overall, Asus' new Transformer Book seems solid and elegant. Only the wide bezels of up to 2 cm (~ 0.8 in) make it slightly less beautiful. It is a shame that there is no possibility to take a look at the device's insides. The case of our 10-inch test unit cannot be opened without special tools.

Input Devices

The tablet is accompanied by a small keyboard that fits the size of the tablet perfectly. The keys are noticeably smaller, which takes a bit of getting used to. But we were more surprised to find that the keys still have comfortable travel and a precise pressure point. Once we were used to the keyboard, we had no difficulty typing for a prolonged period of time. Only the grip could be a little better, and the keyboard gives way a lot due to being propped up at the back. This is not an issue with the device's competitors as they have a solid keyboard.

Below the keyboard you have a touchpad that is 8.7 x 4.6 cm (~3.4 x 1.8 in) large. We would have wished for this to be bigger. It responds well and quickly to most inputs, although there are some difficulties in the corners, as well as with gesture control. Inputs with several fingers are often not registered properly. When working for a prolonged period of time, we would suggest using a physical mouse or moving to the touch display.

The device can also be acquired with a pen for the touch display. This has over 1024 levels of pressure sensitivity and can be stored in a flap on the side of the keyboard.

Display

pixel array

Asus has given its 10-inch convertible a 1280x800 pixel screen. The panel comes from AU Optronics and has a glossy surface. If your eyes are used to great display resolutions, the low resolution might be a little annoying as the pixels are clearly visible if you look closely. Lenovo's IdeaPad Miix has a significantly better pixel density, thanks to its resolution of 1920x1200.

But Asus can offer something else: Great display brightness. This is just under 500 cd/m², which means that the convertible can even be used outdoors. The IdeaPad that we just praised reaches only 244 cd/m², which is half of what the Transformer Book can do. Please be aware: The display brightness of the Asus Transformer Book drops to 426 cd/m² when running on battery.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
28 ms ... rise ↗ and fall ↘ combined↗ 15 ms rise
↘ 13 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 59 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
29 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise

The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 14 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (41 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 294 Hz ≤ 80 % brightness setting

The display backlight flickers at 294 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 80 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 294 Hz is relatively high, so most users sensitive to PWM should not notice any flickering. However, there are reports that some users are still sensitive to PWM at 500 Hz and above, so be aware.

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8931 (minimum: 43 - maximum: 142900) Hz was measured.

Our test unit displays colors well too. Thanks to its IPS panel, the DeltaE deviation of colors and gray scales is below five. However, the color-space coverage is rather low (77% sRGB). Neither of its competitors does better in this respect.

Performance

LatencyMon with some issues
LatencyMon with some issues

The performance is mainly influenced by an Intel Atom processor. This should provide well for most day-to-day activities. As we already know from the Acer Switch One 10, 4 GB of RAM should not be taken for granted. Although Asus has equipped our test unit with a memory of this size, single-channel operation makes an additional boost impossible. Overall, the tablet is focused on the occasional office use and surfing the web. Price: $370.

Processor

The processor is an Intel Atom x5-Z8350 that has four cores and a clock rate of up to 1.92 GHz. The Quad-Core SoC has been around for a while and was first used in February 2016. With a TDP of under 4 W, the CPU is particularly interesting for small, narrow Windows tablets. The 10-inch Lenovo competitor is also equipped with this processor. In our next step, we compared the performance of both processors with the help of Cinebench R15. Our current test unit received 100 points, which is what we expected. During the test, the CPU clocked at 1.7 GHz almost constantly. The clock rate remained the same on battery. The IdeaPad reached 92 points, which is about 7% worse than our Transformer Book. For more comparisons between other tablet processors, please take a look at our benchmark table for notebook processors.

Graphics

The Intel HD Graphics is part of the Cherry Trail architecture and takes care of the graphics performance in our device. It can only cover everyday use and is not good enough for the gaming world. This is underlined by the results of the 3DMark 11 (about 400 points). The results of the competition were not as good. Both the Lenovo IdeaPad Miix 320 and the Acer Switch One 10 only reached 340 points. The results of our test unit remain the same when running on battery.

stress test

As the components of our test unit are only cooled passively, it is particularly interesting to take a look at the temperature development of the case and inside the device itself. The convertible does not heat up that much while idling or under load. The maximum temperature on the display unit is 39 °C (~102.2 °F).

In order to measure the maximum temperatures inside the device, we put the test unit under load for over an hour. It did not take long for the CPU to throttle and drop to way below its base clock rate. At the end of the test run, the clock rate was an average 500 MHz.

The device could resume full performance almost immediately after the stress test was finished. The 3DMark 11 result was only minimally lower than before, at 374 points.

The built-in speakers are rather quiet. Apart from that, the sound is quite clear when reproducing speech, which you can see by the linear course of the frequency diagram. We did notice some difficulties with playing music: The bass frequencies are just not there and the high frequencies too present.

Frequency diagram in comparison (check boxes can be turned on/off!)

Power Consumption

The Asus Transformer Book consumes only up to 6 watts. Even under load, the power consumption is good at up to 13 watts (14 watts for a short period). The competitors need up to 2.5 watts less, however, which could be due to their lower performance and display brightness.

Battery Runtime

Asus has equipped the Transformer Book with a 32 Wh (31 Wh according to the battery report) Li-ion battery with two cells. In order to measure a realistic runtime, we simulated surfing the web. With screen brightness set to about 150 cd/m², we could surf for 10 hours. Again, the competition could not keep up. The cheaper Acer Switch One still reached almost 9 hours, while the Lenovo device lasted for only 7 hours and 41 minutes.

Verdict

the Asus Transformer Book, test unit provided by notebooksbilliger.de
the Asus Transformer Book, test unit provided by notebooksbilliger.de

An old and trusted concept has been implemented successfully. Asus is considered a pioneer of convertible products and has now presented us with a small 10-inch device with a Windows operating system. The case is made of high-quality material and is stable. Only the wide bezels interfere a little with the overall impression. The accompanying keyboard unit that docs on to the device has slightly smaller keys than usual. As the keyboard is comfortable to use apart from this, it is easy to get used to. The touchpad, however, could still be improved. We were also disappointed by the low resolution of the display. Its brightness on the other hand was a very pleasant surprise. The device also offers good performance and stayed ahead in the benchmarks compared to its competition. Even the battery runtimes of this convertible are good.

The new 10-inch Asus Transformer Book proves to be a capable companion.

If you do not want to splash out too much and are just looking for a mobile secondary device, you could also take a look at the Acer Switch One 10. The Lenovo IdeaPad Miix has an LTE module for mobile internet connection.
