Asus Chromebook Flip C434TA in review: Silent convertible offers good endurance

Sascha Mölck, 👁 Sebastian Jentsch, Andrea Grüblinger (translated by Stephanie Chamberlain), 01/22/2020

Chromebook convertible. The Asus Chromebook Flip features a Core m3-8100Y processor, an IPS touchscreen display and good battery life. The integration of the Google Play Store allows the use of countless Android apps.

The Asus Chromebook Flip C434TA is a slim, compact 14-inch convertible. The computer is powered by a Core m3 processor of the Amber Lake generation. Direct competitors include the Dell Inspiron 7486 Chromebook 14 2-in-1 and the HP Chromebook x360 14 G1. But the device also competes with Windows convertibles such as the Acer Spin 3 SP314-51, the Lenovo IdeaPad C340-14API, the Asus VivoBook Flip 14 TP412UA and the HP Pavilion x360 14.

Case and connectivity - Asus gives the C434TA a fancy metal case

Asus has opted for a fancy, slim, silver metal case in the Chromebook, which, despite having a 14-inch screen, is about the size of a 13.3-inch device. The resulting slim display bezel increases the computer's visual appeal. There's nothing to complain about in terms of workmanship. The gap dimensions are in order, and there aren't any sharp edges. We see a need for improvement in regard to stability since the base unit can be twisted too easily.

The convertible doesn't come with a maintenance hatch. In order to reach the inside, the bottom cover must be removed. Opening the case would only be necessary for the replacement of the battery or the motherboard. After removing all the screws on the bottom, the bottom cover can be detached with the help of a grout finishing tool. Attention: Further screws are hidden under the two rear rubber feet.

The C434TA has three USB 3.2 Gen 1 ports (1x Type-A, 2x Type-C). The two Type-C ports are used for both power delivery and video output (DisplayPort via USB-C; this requires a separately available adapter).

The built-in microSD memory card reader is located in the medium speed range. The transfer of 250 JPG image files (each of about 5 MB) is completed at a speed of 64.1 MB/s. We test memory card readers using a reference card (the 64 GB Toshiba Exceria Pro M501 microSDXC).

The Wi-Fi module uses an Intel chip (Dual Band Wireless AC 7265). In addition to the 802.11 a/b/g/h/n Wi-Fi standards, it also supports the fast ac standard.

Input devices - The Chromebook convertible offers keyboard backlighting

Asus has equipped the convertible with a backlit chiclet keyboard. The flat, slightly roughened keys have a short travel and a clear pressure point. The resistance provided by the keys is in order. While typing, the keyboard gives way slightly. It didn't prove to be bothersome. All in all, the keyboard has proven its suitability for everyday use. Moreover, the lighting offers five brightness levels. However, the characters on the silver keys are difficult to see when you're in a bright environment and the backlight is active.

The multitouch ClickPad takes up an area of about 10.5 x 6.2 cm. This means that there is plenty of space available to use gesture control. The pad's smooth surface makes it easy for the fingers to glide over it. The pad has a short travel and a clear pressure point.

Display - IPS on board of the C434TA

The glossy 14-inch touchscreen display has a native resolution of 1920x1080 pixels. Brightness (272.3 cd/m²) and contrast (754:1) are too low. We see values beyond 300 cd/m² and 1000:1 as good. In addition, the display is very unevenly illuminated. At least it shows no PWM flickering.

Out of the box, the display shows a quite decent color reproduction, and it doesn't suffer from a blue tint.

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
34 ms ... rise ↗ and fall ↘ combined↗ 19 ms rise
↘ 15 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 87 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.9 ms).

In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 77 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.6 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 not detected

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 13646 (minimum: 43 - maximum: 2500000) Hz was measured.

Asus equips the Chromebook with a viewing-angle-stable IPS panel. Therefore, the screen can be read from any position. The screen readability outdoors goes from poor to nonexistent - especially in bright sunshine. The convertible is primarily designed to be used inside buildings.

Emissions and energy - Asus notebook operates quietly and barely heats up

Noise emissions

The Chromebook is cooled passively and doesn't have a mechanical drive on board. Therefore, the device works silently.

Temperature

The C434TA hardly heats up over the entire load range. Under load, we register temperatures slightly above 30 °C (~86 °F) at some measuring points. When idle, the values are clearly in the green range. In order to stress test a Chromebook, we run Google's Octane V2 benchmark and the Jetstream benchmark in a loop.

Speakers

The stereo speakers are located on the bottom of the device. They produce an acceptable sound, which is missing bass, however. In addition, the maximum volume is too low. For a better sound experience, the use of headphones or external speakers is recommended.

Verdict

The Asus Chromebook Flip C434TA (90NX0231-M03340), provided by Asus Germany.
The Asus Chromebook Flip C434TA (90NX0231-M03340), provided by Asus Germany.

Asus wraps the technology of the Chromebook Flip C434TA in a fancy, slim, compact metal case that's about the size of a 13.3-inch device. However, the convertible has a 14-inch display, making it a device with a thin display bezel. 

The convertible is powered by a Core m3-8100Y processor that provides enough computing power for office and Internet applications. A decoder that's built into the GPU unloads the processor when playing videos. Therefore, using streaming services doesn't pose a problem.

The available storage space is not too generous at 64 GB. An expansion of the storage space would be possible via a microSD card. Good: The Chromebook comes with two USB Type-C ports through which the device can be powered. Both ports also support the DisplayPort via USB-C function.

The main problem of the Asus Chromebook Flip is its price or rather the weaknesses it reveals despite a price level of 640 Euros (~$710) to 720 Euros (~$799). You can just as well go for a much cheaper Chromebook.

The IPS touchscreen display scores points with stable viewing angles. But the brightness and contrast are too low for a device in the current price range. In addition, the display's brightness distribution turned out to be too uneven. The built-in keyboard has proven to be suitable for everyday use. Pros: Backlighting is available, which is complemented by very good battery life.
