Asus ZenBook 14 UM431DA laptop review: Also makes a good impression with Ryzen

Mike Wobker, 👁 Sebastian Jentsch, Andrea Grüblinger (translated by Stephanie Chamberlain), 02/15/2020

Zen-tastic. The Asus ZenBook 14 also makes a good impression with AMD's stronger Ryzen 7 but can't reach its full performance potential despite the fans turning up. With its flat design, the 14-inch laptop stays handy as usual and small features such as the integrated number pad are fun. Our review shows what else is found in the ZenBook 14.

Asus ZenBook 14 UM431DA-AM020T

In addition to the ZenBooks 14 UX433FA and UX433FN with Intel processors that we've already tested, we also have a model with an AMD CPU in hand now. It includes a powerful AMD Ryzen 7 3700U processor with a Radeon RX Vega 10 graphics unit and 8 GB of RAM, as well as a 512 GB SSD. With its handy size, it's aimed at mobile users who want to work on a variety of office tasks on the go too.

In this review, we compare the Asus ZenBook 14 UM431DA-AM020T with the competitors listed below. Under each section, however, you can also add more laptops from our database for comparison.

Case - Stable but prone to scratches

The case of the ZenBook 14 is made of metal and features a brushed surface. Due to the selected material, the small laptop looks very robust but is prone to scratches. A trim bar below the screen provides an optical enhancement, and grills to the left and right of the keyboard hide the speakers.

For ZenBooks, the lifting mechanism has almost become a trademark, which causes the base to move slightly upwards when the lid is opened. This promotes air circulation but also creates an unpleasant edge if you want to use the laptop on your lap, for example.

Despite its robust material, the Asus ZenBook 14 UM431DA is one of the lightest laptops in our test field. Among the 14-inch competitors, it is much more compact, especially in its depth, but it's on average for the other dimensions.

Connectivity - ZenBook 14 offers a USB Type-C port

The ZenBook 14 offers the most necessary ports but can be extended via the USB Type-C port and with appropriate adapters or a docking station. The ports are located on the sides at the rear of the laptop, so cables lying in the way don't represent a problem.

SD card reader

Asus has built an SD card reader into the ZenBook 14, whereby corresponding cards can only be inserted about one centimeter into the case. As a result, a large part of the storage medium sticks out, so that SD cards can't remain in the laptop during transport.

With our Toshiba Exceria Pro SDXC 64 GB UHS II reference memory card, the car reader only reaches below-average speeds of 26.4 MB/s for reading and 37.1 MB/s for writing data.

Accessories

In the box, the Asus ZenBook comes with the laptop itself and a matching 45-watt power adapter. The variant we tested was also accompanied by a suitable carrying case. However, buyers must ensure that this is actually included in their offer. Without a case included, the Asus ZenBook 14 is usually offered a little cheaper.

Maintenance

The base cover of the Asus ZenBook 14 can be removed after all Torx screws at the bottom have been loosened. This frees up access to the interior, whereby only the Wi-Fi module and the SSD can be replaced. Memory is firmly soldered, and a free RAM slot isn't available either.

Warranty

Asus grants buyers of the ZenBook 14 UM431D a 24-month warranty period.

Input devices - Asus laptop with number pad

Keyboard

The keys of the ZenBook 14 UM431D have a size that is suitable for writing tasks. The pressure point can be felt clearly, but due to the smooth surface, individual keys aren't always met accurately. Even after an adjustment period, incorrect inputs keep happening, and the very small function keys can only be used if you look closely at them. The three-stage backlight ensures a non-dazzling illumination of the key labels in the dark.

Touchpad

As mouse replacement, Asus uses a ClickPad that is suitable for precise mouse pointer navigation due to its average size. Both left and right mouse clicks can be triggered correctly by touching or applying pressure on the pad. There's an icon in the upper right corner that allows a number pad to be projected onto the ClickPad. In doing so, mouse navigation still remains available, but touch inputs trigger the corresponding input of the number pad. This worked very well in our test and shows itself as a meaningful addition to the keyboard.

Screen bleeding

The screen of the Asus ZenBook 14 consists of a 14-inch IPS panel and offers a resolution of 1920x1080 pixels. The brightness is on the second to last place of our test field with an average of 245 cd/m² but can be described as sufficient. On the other hand, the brightness distribution is below average at only 78%, and there is evident screen bleeding in the lower right corner.

Asus hasn't completely forgone PWM for brightness control. In this way, brightness levels of less than 20% show flickering at a frequency of 44 Hz. Since this is a very low value, even users with less sensitive eyes could also notice an effect. However, the consequences of this will vary depending on the brightness set.

Our measurements certify a good contrast ratio of 1,124:1 for the Asus ZenBook 14 and an equally good black value of 0.225 cd/m². This makes colors look well separated from each other and blacks are displayed relatively richly.

The CalMAN analysis also shows that colors are displayed with a slight deviation but with components shifting to green. This can be compensated for by calibration, whereby the deviation remains, but the color components are somewhat shifted. The corresponding ICC file can be downloaded in the window located at the top, to the right of the display's brightness distribution graph.

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
26 ms ... rise ↗ and fall ↘ combined↗ 15 ms rise
↘ 11 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. » 46 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.9 ms).
       Response Time 50% Grey to 80% Grey
36 ms ... rise ↗ and fall ↘ combined↗ 19 ms rise
↘ 17 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 30 % of all devices are better.
This means that the measured response time is similar to 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 detected 44 Hz ≤ 20 % brightness setting

The display backlight flickers at 44 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 44 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

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.

The IPS panel of the ZenBook 14 is very viewing-angle stable. Image content can be viewed from almost any angle without it becoming distorted or showing the wrong colors.

Performance - Good system performance despite weak CPU

With AMD hardware, the Asus ZenBook 14 also targets users looking for an ultra-mobile, small and lightweight laptop for everyday office use. The manufacturer offers the device with a larger number of hardware variants, but they all belong to the category of office devices with built-in graphics cards. In addition, there are variations in the built-in memory and storage.

 

Processor

The AMD Ryzen 7 3700U is a quad-core processor that can handle up to eight threads simultaneously. The clock rates are between 2.3 and 4 GHz, whereby the maximum clock speed can only be maintained in the long run with sufficient cooling. In our Cinebench endurance test, the ZenBook 14 can only retrieve the maximum CPU performance very briefly. Afterwards, it drops by about 20% and is then below the level of a Ryzen 5 3500U. The Lenovo ThinkPad E595, for example, shows the kind of performance that's achievable with the Ryzen 7 3700U in the long run.

In the Cinebench R15 single-core and multi-core individual performance tests, the ZenBook 14 achieves values that are just below the average of other laptops with this CPU.

Gaming performance

AMD's Radeon RX Vega 10 is definitely suitable for games. With the 8 GB of RAM installed here, older games with medium graphics levels can be run smoothly. Titles that aren't very graphically demanding can also be easily played in Full HD. The Asus ZenBook had no problems in our test with a resolution of 1366x780, which should be preferred for a smooth gaming experience on this laptop.

The performance that can be expected in other titles with the AMD Radeon RX Vega 10 can be found in our GPU Games article.

Noise emissions

Noise levels
Noise levels

The fans of the ZenBook 14 are usually turned off in daily usage with an active browser and during writing tasks. With slightly more demanding applications, they start to spin with a uniform noise, but they can still easily hide in the ambient noise. Only under full load can the fans be clearly heard. Therefore, the ZenBook 14 should only be used for light tasks while in noise-sensitive environments.

Temperature

Stress test
Stress test

Our measurements show that the ZenBook 14 reaches surface temperatures of up to 25.9 °C (~79 °F) when idle and a maximum of 37 °C (~99 °F) under load. The warmest point is in the rear left area of the laptop, which results in the palm rest always remaining cool.

During our approximately one-hour-long stress test, the clock speeds of the ZenBook 14 drop to 1.2 GHz. In doing so, the base clock speed is significantly undercut and isn't reached again for the rest of the test. Since our stress test represents a load that shouldn't occur in practice, however, users don't have to expect restrictions due to temperatures being too high.

Speakers

The speakers of the Asus ZenBook 14 are relatively quiet and offer a sound spectrum with pronounced mids. This makes the small laptop only suitable for media playback in very quiet environments. In the long run, users should favor external speakers or headphones, which can be connected via the 3.5 mm audio jack. This holds corresponding plugs firmly in place and doesn't negatively affect sound quality.

Battery life

In our practical Wi-Fi test, the ZenBook 14 achieves a runtime of just under 7 hours. This value is only average since other laptops from our test field with partly smaller capacities last longer. Under full load and idle operation, however, the Asus laptop performs better than our chosen competitors.

In review: Asus ZenBook 14 UM431DA. Test device provided by:

With the Asus ZenBook 14 UM431DA, buyers get a laptop with a great design and that is easy to transport for a comparatively low price. The case looks very high-quality, and various decorative elements give the impression of it being more expensive. Added to this there's the feature of the integrated number pad, which turned out to be a useful addition to the keyboard. The port configuration is solid, and while Wi-Fi 5 isn't a big leap, wireless connections are still fast and up-to-date.

The ZenBook 14 is a solid laptop with an appealing design. Unfortunately, it can only exploit the power of its CPU moderately.

However, prospective buyers should not limit themselves to this model with the Ryzen 7 3700U but can confidently reach for the next weaker CPU. Since the cooling system can only support full performance very briefly, the long-term performance is well below the expectations we set for this processor. Because the memory can't be upgraded, its size also needs to be taken into account in the determination of a suitable model before purchasing. If you're mostly interested in the design and bare numbers, and not necessarily in the actual performance, you can still buy this laptop without hesitation.
