The VivoBook 14x in our test had an all-plastic silver gray chassis, but it also comes in midnight blue. A simple “Asus VivoBook” inscription is on the cover, the rest of the design is very basic.
Opening the screen shows the keyboard in the same color as the chassis. The matte screen is surrounded by a grainy black plastic with poor quality rendering.
If the keyboard has a backlight, we know that the gray keys do not blend well with it. Therefore, during the day, when the backlight is activated, the keys may not be read due to the lack of contrast; a problem that disappears in the midnight blue version with black keys.
The sensations of typing on the keyboard are correct, although the mechanism of the keys can be heard quickly.
The touchpad provides a good glide considering the gestures of Windows. Note that the VivoBook 14x has the simplest version of the NumPad, with a numeric keypad screen that is activated by pressing for a second in the upper right corner.
Note that the VivoBook 14x does not have a fingerprint reader, a practical system for quickly opening a Windows session.
Almost full connection side box. So there are three USB-A ports, including one of USB2.0 and two of USB3.2 (5 Gb/s). There is a USB-C port, but does not support charging. Finally, an HDMI 1.4 port and a mini-jack socket complete the 4 USB ports. What is missing is a memory card reader to complete this connection.
The wireless connection is provided by a Mediatek MT7921 chip that offers wifi 6 at 2400 Mb/s and Bluetooth 5.2. The webcam located above the screen has a 720p sensor with very fuzzy and noisy rendering in the dark. A sliding physical cover hides the sensor for added privacy. This webcam is not compatible with Windows Hello.
The cooling system consists of two heat pipes that transfer the calories released by the Ryzen 5 5600H to two radiators arranged in the left corner of the chassis. A fan removes heat from both radiators.
After our traditional encoding test, the thermal camera revealed a hot spot of 41°C on the keyboard keys and almost 45°C on the piano. On the other hand, the noise pollution is relatively contained (36.7 dB measured). In use, the fan stays off as long as the laptop is not in use. It only triggers during Windows updates or while in use. A Performance mode allows you to increase the ventilation to get more power, but the noise pollution disappears.
Access to the components requires the removal of 10 Phillips screws and the removal of the hull. The VivoBook 14x has proven to be upgradeable. It is possible to replace the RAM, the SSD, the wifi card and the battery. Sold 8 GB of RAM and installed an 8 GB module. So it is possible to transfer to 24 GB by replacing the latter with another 16 GB. Despite this good scalability, Asus announced a repairability index of only 6.3 / 10 for this VivoBook 14x.
The VivoBook 14x is equipped with an AMD Ryzen 5 5600H processor with 6 hyperthreaded cores running at 3.3 GHz and up to 4.2 GHz with a thermal envelope of 45 W. This processor is often used in laptops. play entry-level. Asus has paired it with 16 GB of RAM and a 512 GB SSD.
The VivoBook 14x thus obtained a performance index of 105, which places it between the MSI Modern 15 and the Core i7-1255U (95) and the ZenBook 14 Oled with a Core i7-1260P. The Huawei MateBook 16 equipped with the same processor gets a performance index of 110 thanks to a bigger and better cooled chassis.
So, during our twenty minutes of encoding, the Ryzen 5 5600H ran at an average of 3.43 GHz in a 35-watt envelope. The cooling system (set to normal mode by MyAsus) is therefore a bit limited for Ryzen 5 to fully express itself. However, it is possible to switch to Performance mode to overcome this problem.
The VivoBook 14x does not have a dedicated graphics card. So it’s the Vega 7 graphics part integrated into the processor that takes care of the task. If you really want to play, you should limit yourself to games that are a bit dated or don’t consume a lot of graphic resources.
The 512 GB SSD from Micron reaches 2.24 GB / s in reading and 1.15 GB / s in writing. We are far from the best SSDs, but it is more than enough for Windows, which starts quickly and is fully responsive.
So Asus abandoned Oled and equipped this VivoBook 14x with a 14-inch IPS panel. Small innovation, we have the right to a panel in 16/10 format that shows 1920 x 1200 px at 60 Hz. Apart from this slight increase in height, the integration does not benefit from particular care and the screen occupancy rate reaches the ceiling of 83%.
Under our review, the panel chosen by Asus lacked precision. Delta E reaches 5.3, more than the threshold of 3 below where the eye can no longer see colorimetric drifts. The color temperature is 6227 K, slightly below the video standard (6500 K), which causes a rather warm rendering. The contrast on the other hand is good for an IPS panel (1560:1 measured). We are certainly far from the infinite contrast of an Oled panel, but it is always good to take. Finally, the maximum brightness of 327 cd / m² allows you to enjoy the full screen indoors, but not outdoors, despite the low reflectance of the panel (18.7% of reflected light).
We provide you with a colorimetric profile that reduces delta E to 3.7, while maintaining other characteristics; the brightness only drops below 290 cd/m².
The two speakers of the VivoBook 14x are located under the chassis. A setting that changes the sound reproduction depending on the surface on which the laptop rests. Also, the hands cover the sound when typing.
Listen, the sound of the voice is not very high. It is possible to hold a conversation even with the volume pushed to the maximum. The rendering is characteristic of a laptop PC, with a sound stage centered on the mids and very lacking in bass.
The headphone output has good characteristics. Distortion is low, dynamic range is high and crosstalk is limited. The real fault, the output level is very low and requires pushing the volume to enjoy it; Headphones with high impedance should be avoided.

Activity / Autonomy
The Asus VivoBook 14x measures 32 x 21 cm and is 1.99 cm thick. So it takes up less space, but is thicker; without any real reason for that, because it is not embedded in any non-standard component. The weight of 1.6 kg puts it 400 g beyond the LG Gram 16 which even has a 16-inch screen and an 80 Wh battery (compared to 50 Wh for this VivoBook 14x). The 90 W charger weighs 333 g and is therefore close to a 2 kg bar in total. Asus could also offer a more compact USB-C charger and thus provide a proprietary socket.
In terms of battery life, the Asus VivoBook 14x is good. It lasted 7 h 28 min of video playback with its screen set to 200 cd/m² (70% of maximum brightness) under our usual protocol (Netflix video playback, 50% volume and Bluetooth off). A proper autonomy, especially if we consider the battery capacity of 50 Wh.
