The simplicity of Chromebooks is pleasing: Open, log in and get started. Users do not have to fuss with the laptop's software or configuration. Acer now has the 13.3-inch Chromebook R13 convertible in its portfolio. The installed touchscreen will first prove its practicality when Android apps can be used officially on the Chromebook R13. The Chromebook competes against devices such as HP's Chromebook 13 G1 Core m5Acer's Swift 1HP's Stream 13HP's Stream 13 and Lenovo's E31-70.

Case and Connectivity

Acer's Chromebook proves that using metal does not automatically mean a solid casing. The base unit can be dented in the usual places (on both keyboard sides, below the touchpad). Furthermore, it is easy to twist. This is also true of the lid. At least this does not cause image distortions, even when pressure is applied to the lid's back. The use of aluminum primarily makes the Chromebook look stylish, but it does not contribute to the devices robustness.

The laptop features a USB 3.1 Gen1 port (Type-C) for connecting the power supply. It can, however, also be used for connecting USB peripherals. A monitor can also be connected. However, a Type-C USB-to display-port adapter would be needed (not included). The addition of another video-out to the already existing HDMI port in the Chromebook would enhance the device significantly. 

The installed Wi-Fi module supports the fast ac-standard (2.4 and 5 GHz). Acer relies on a solution with two antennas (2x2 MIMO).

Android Apps @ Chromebook

Acer's Chromebook R13 is on the 2017 list of devices that can be equipped with Android apps from Google's Play Store. At the time of our test, no corresponding Chrome OS update was available. However, a beta version of Chrome OS that allows using Android apps can be installed via the beta channel. Naturally, we tried this out: The use and installation of these apps functioned mostly smoothly. We ran some Android benchmarks using the Chrome OS. However, not all apps are yet ready for use with the Chrome OS. For example, MS Word and MS Excel cannot be installed. Some apps cannot be used via the keyboard - the game "Asphalt 8: Airborne" is an example. And this is where the touchscreen in the Chromebook R13 becomes useful.

Input Devices

Acer's Chromebook is equipped with an unlit chiclet keyboard. The flat, roughened keys have a medium drop. The pressure point is rather spongy and the keys' resistance could be crisper. The keyboard yields slightly when typing on it. Acer delivers a keyboard designed for home use; prolific typists will not be happy with it. The installed ClickPad replaces a mouse. It has an area of approximately 10.5 x 6 cm (~4.1 x 2.4 in). Its sleek surface allows the fingers to glide easily. The pad has a short drop and clear pressure point.

The touchscreen supports 10 touch points. It did not cause any problems and responded quickly to inputs. The screen can be used with the fingers or an active stylus.

The 13.3-inch touchscreen has a native resolution of 1920x1080 pixels (Full HD). The screen's brightness is too low (204.3 cd/m²), but its contrast (835:1) is satisfactory. Positive: The screen never displays PWM flickering.

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: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9064 (minimum: 43 - maximum: 142900) Hz was measured.

The screen presents a relatively balanced color reproduction in the state of delivery. It does not suffer from a bluish 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
23 ms ... rise ↗ and fall ↘ combined↗ 5 ms rise
↘ 18 ms fall
The screen shows good response rates in our tests, but may be too slow for competitive gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 28 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (25.6 ms).
       Response Time 50% Grey to 80% Grey
38 ms ... rise ↗ and fall ↘ combined↗ 14 ms rise

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 34 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (41 ms).

Acer has equipped the Chromebook with a viewing angle stable IPS screen. Thus, the screen is legible from all positions. The laptop is not really suitable for the outdoors. The combination of low brightness and glossy surface has a negative effect here.

Performance

Acer's Chromebook R13 is a 13.3-inch convertible. Our review sample is priced at approximately 400 Euros (~$425). Other configurations were not available at the time of testing.

Processor

A passively cooled MT8173C SoC from MediaTek is inside the Chromebook. This ARM SoC has a total of four CPU cores: Two Cortex A72 and two Cortex A53 cores that create the so-called big.LITTLE array. Here, two high-performance cores (A72; max. 2.1 GHz) and two energy-saving cores (A53; max. 1.7 GHz) are combined to ensure that the highest possible performance is available when required, but the battery is not depleted in idle mode or low load. It is also possible to use all four cores simultaneously, so that this is a genuine quad-core processor.

System Performance

The system runs smoothly, and we did not encounter any problems. The Chrome OS boots within seconds and applications launch quickly.

Storage Device

An eMMC module with a capacity of 32 GB serves as the system drive. The storage capacity can be expanded via a microSD card when required.

Graphics Card

The PowerVR GX6250 GPU is responsible for video output. The graphics core has been on the market since mid-2014 and is consequently not one of the latest models. It reaches speeds of up to 700 MHz, and the integrated decoder unloads the processor when playing videos. H.264, H.265/HEVC, and VP-9 formats are supported.

Emissions and Energy Management

System Noise

The SoC installed in the Chromebook is cooled passively. Thus, a fan is not present. The laptop does not produce any other side noises.

Temperature

It cannot really be said that the Chromebook heats up. The laptop is lukewarm in idle mode. The temperatures do not increase much during load either. 30 degrees Celsius (~86 degrees Fahrenheit) is exceeded on only two measuring points. To simulate the stress test, we run Google's Octane V2 benchmark on a loop and play a Full HD video at the same time.

Acer's Chromebook R13 relies on ARM technology with the MT8153C SoC. The SoC allows passive cooling that is also implemented here. Thus, the Chromebook runs silently. Acer does not present a run-of-the-mill device with its Chromebook R13. It is a 13.3-inch Chromebook convertible. A touchscreen in a Chrome OS device is basically a superfluous feature. However, this will change as soon as Android apps officially run on Acer's Chromebook. A Wi-Fi module for Internet access, which supports the fast ac-standard, is installed. Furthermore, the Chromebook can serve with an outstanding battery life.

A charged battery will last the user through a workday or a day at school/university.

The laptop's metal casing is attractive primarily due to its looks, but we would expect more in terms of stability. The keyboard is sufficient for home use, but it is not designed for prolific writers. The installed IPS panel pleases with stable viewing angles and good contrast, but its brightness is too low.
