MagyarAsus ZenBook 13 Review - A compact 13-inch laptop with a fast Ryzen 7 5800U and OLED display
While the Asus ZenBook 13 UM325S is one of the light subnotebooks in the 13.3-inch format, the compact device is still run by a native octa-core SoC. To be exact, it is the AMD Ryzen 7 5800U, which is based on the Zen3 architecture and brings many improvements. The SoC is accompanied by 16 GB of working memory and the large 1-TB SSD ensures sufficient storage. With the iGPU in form of the Vega 8, the new SoC does not really bring anything new. However, the iGPU of the Ryzen 5000U APUs now has a slightly higher clock speed, so we should also expect more performance here. For the display, Asus uses an OLED panel that is quite able to convince. Our review lists more details below.
The competitors of the Asus ZenBook 13 UM325S include devices such as the Huawei MateBook X Pro 2021, the Lenovo Yoga Slim 7i Carbon 13 ITL, the HP Envy 13-ba0001ng, the Lenovo ThinkBook 13s-ITL, and the Dell XPS 13 9310 Core i7 FHD.

Case - Modern and slim
Asus uses high-quality materials in the ZenBoook 13. To a large extent, it is made from aluminum, which brings some good stiffness to the case. The workmanship offers no reason for complaint, and the haptics of the surface also have a high-quality feel and offer a good grip. Fortunately, the surface does not show fingerprints easily either. As already mentioned, the stiffness of the base unit and display lid is good, even though the center of the base can be pressed down slightly in our pressure test, but this not very pronounced.
The hinges are very easy to move and allow single-handed opening of the display. However, if you set down the device a bit too quickly on the table, the display tends to bounce toward the back. While this is something that is easy to live with, we still would have preferred hinges that are a little tighter.
The footprint of the Asus ZenBook 13 is smaller than that of most of the competitors. Only the HP Envy and the Dell XPS 13 use even less space, but they are also slightly thicker compared to the Asus ZenBook 13. At only 13.9 mm (~0.55 in), our test unit is very slim, and with its 1.2 kg (~2.6 lb), it is also pleasantly light. You also have to consider the charger, which weighs an additional 260 grams (~0.44 lb).
Equipment - Reduced to the bare minimum
In terms of the equipment and particularly the external connections, the ZenBook 13 UM325 does not offer a large selection. However, all the most important ports are available and you can add more via adapter. The three USB ports are sufficient, even if one of the Type-C ports is occupied by the charger. The HDMI port also allows you to easily connect an external display to the compact ZenBook 13 UM325. Those who prefer to use DisplayPort can do this via a corresponding adapter for USB Type-C. Both of the Type-C ports support this option. In addition, there as also a microSD card reader.
Communication
The Asus ZenBook 13 UM325 is equipped with an Intel AX200 Wi-Fi 6 module. In everyday operation we found no problems in the WLAN connection. Unfortunately, the ZenBook 13 UM325 does not offer an Ethernet connection.
Security
In terms of the security features, the ZenBook 13 UM325 only offers an Infrared camera, which supports the Windows Hello function and facilitates logging into the system.
Accessories
The laptop includes the 65-Watt charger and a corresponding sleeve. However, this can only fit the laptop and not the charger.
Maintenance
Any maintenance tasks turn out relatively easy to perform, even if there is no specific maintenance flap. The bottom of the case can be easily removed with the right tools. However, you have to make sure to remove all the screws, since two of them are right underneath the rubber feet in the back. The user is not offered many expansion options, and only the SSD can be replaced fairly easily, if needed.
Warranty
Asus offers buyers of the ZenBook 13 UM325 a 24-month warranty including pickup and return service.
Input Devices
Keyboard
The 6-row chiclet keyboard of the ZenBook 13 UM325S offers a discreet background illumination that can be adjusted in three steps of brightness. While the surface of the keys is quite smooth, it still offers a good purchase to the fingers. The short stroke in combination with it not being overly dampened offers a good typing experience. The keys don't produce any annoying noises while typing. The pressure point is clearly noticeable. After a short period of getting used to the slightly smaller arrow keys, frequent typists should quickly be able to make good use of the keyboard.
Touchpad
With its 13 x 6.5 cm (~5.1 x 2.6 in) footprint, the ClickPad has a decent size, making optimal use of the available space between the palm rests. As a highlight, the ClickPad offers a number block that can optionally be activated. In addition, you can adjust the brightness of the displayed numbers and symbols in two steps. The ClickPad surface is very smooth, which becomes a slight disadvantage with sweaty fingers. The touchpad responds to touch quickly, and accurate input up to all the corners is not problematic. The lower areas contain the two input keys, which respond to pressure with a pleasantly quiet click to indicate successful operation.
Display - OLED with great colors
The built-in display is a 16:9 OLED panel with 1920 x 1080 pixels (FHD) and a 13.3-inch diagonal, resulting in a pixel density of 166 PPI. However, with an average brightness of 370 cd/m², our ZenBook only places in the middle of the field of the comparison devices. On the other hand, the very low black value reflects the strengths of the OLED technology, also resulting in a very good contrast ratio. In addition, the so-called "clouding" is not an issue, since the display does without the large-area background illumination. To prevent burning-in effects, a refresh/PWM approach is used. At full brightness, we measured a frequency of 60 Hz.

* ... smaller is better
The measured Delta-E 2000 color deviations compared to the sRGB color space are already at a good level in the state of delivery, which means that Asus sells the ZenBook 13 with a precalibrated display. However, with 4.33 in the colors, the Delta-E 2000 value is still slightly above the target value of 3. When we then performed another calibration, the Delta-E 2000 value in the colors was slightly improved, even though you can notice a slight worsening in the grayscale. However, it still remained below the targeted value of 3. In the measured color space coverage, the Asus ZenBook 13 UM325S scores with very good values that are quite suitable for usage in the professional field.

The display backlight flickers at 60 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 100 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 60 Hz is very low, so the flickering may cause eyestrain and headaches after extended use. In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 17900 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
As expected, the Asus ZenBook 13 UM325S also fares well in our viewing angle test. The viewing angles of the OLED display are very stable, and the test image can be seen easily from all the viewing angles. However, working outdoors and in direct sunlight using the Asus device becomes a bit problematic, since the glossy surface causes strong reflections on the screen that can become very annoying at times.
Performance - AMD Ryzen 7 APU with 8 cores

Graphics Card
The Asus ROG ZenBook 13 UM325S offers a solid performance with the AMD Radeon RX Vega 8. At the same time, it becomes increasingly difficult for the integrated graphics unit to compete against the models from Intel. The result is a slight disadvantage compared to the Intel Iris Xe Graphics G7. However, the difference between the two iGPUs is not really noticeable. Although the Asus ZenBook 13 UM325 does not offer a dedicated graphics unit, the AMD Radeon RX Vega 8 in our test unit performs very well, compared to the average of the class.

Gaming Performance
In the gaming performance, the weak GPU performance forces us to lower our sights. With current games, the AMD Radeon RX Vega 8 is only able to produce smooth frame rates in low resolutions and at minimal detail settings. On the other hand, it is possible to play older or less demanding games in the native resolution and at higher detail settings.

Emissions
Noise Emissions
The measured noise emissions show that our Asus subnotebook often remains pleasantly quiet during its operation. During regular operation, the fan revs up from time to time and then also becomes quietly noticeable. In addition, the slightly high-frequency fan noise creates a subjectively higher noise level. During idle operation or lower loads, we measure only slightly above 30 dB(A). Under load it can be up to 37.2 dB(A) at times, which is also the maximum noise level we record during the stress test.

Temperature
The compact design requires some advanced cooling, which Asus implemented well. But the materials used will also ensure good heat transferal overall. The aluminum base is able to absorb and distribute the heat well, but this also means that the case surface will get warm. At a maximum of 43.6 °C (110 °F), the temperatures still remain within the green range. To ensure a perfect air circulation, it is best to run the device on a fixed surface. In addition, the base is slightly raised by the opened display, which on one hand offers a better angle for typing, and on the other, also ensures better cooling of the system.
For the components, this results in a maximum temperature of 63 °C (145 °F) for the built-in AMD Ryzen 7 5800U, and at about 59 °C (138 °F) during the stress test, the iGPU reached about the same level. However, during simultaneous load on the CPU and GPU, the basic clock speed could not be maintained, since both have to share the low TDP. But at 1.6 GHz, the difference to the basic clock speed (1.9 GHz) remains within close range. Running a 3D benchmark right afterwards did not show any negative effect of the extreme constant load during the stress test.
(±) The maximum temperature on the upper side is 42.6 °C / 109 F, compared to the average of 35.9 °C / 97 F, ranging from 21.4 to 59 °C for the class Subnotebook.
(±) The bottom heats up to a maximum of 43.6 °C / 110 F, compared to the average of 39.4 °C / 103 F
(+) In idle usage, the average temperature for the upper side is 30.7 °C / 87 F, compared to the device average of 30.7 °C / 87 F.
(+) The palmrests and touchpad are reaching skin temperature as a maximum (32 °C / 89.6 F) and are therefore not hot.
(-) The average temperature of the palmrest area of similar devices was 28.3 °C / 82.9 F (-3.7 °C / -6.7 F).
Speakers
The two speakers are positioned below the palm rests and are able to use their potential to the fullest on a hard surface. A soft surface will muffle the sound, which also makes it a lot quieter. The two speakers produce a good sound that is quite acceptable. The DTS software also allows you to modify the sound. Due to the compact build the highs are very present, but the mids and bass are also not completely lacking, creating a fairly balanced sound spectrum.
Our test unit did not produce any distortions or additional noises at maximum volume.

Power Management
Power Consumption
Compared to the competitors, the power consumption of the Asus device turns out fairly good. In idle operation, the laptop uses between 7.4 and 11 watts. However, the HP Envy 13 is still the most efficient device here. Under load, our ZenBook 13 UM325S uses an average of 35.7 watts, although the maximum value is only 37.2 watts, which is significantly less than our comparison devices. This also means that the compact 65-Watt charger will not run into any problems with this.

Battery Life
The Asus ZenBook 13 UM325S is equipped with a 67-Wh battery, which is the largest battery in our direct comparison. In our WLAN test, our test unit lasts for a good 9 hours. However, despite their smaller batteries, the competitors are able to achieve better results here, but our ZenBook 13 UM325S does not need to hide either. The device is also suited for a long evening watching movies. It is able to play our test video in a constant loop for 10 hours. For both of these tests, the display brightness is reduced to 65%, to be set at the standardized level of 150 cd/m². You should plan for slightly more than 2 hours to completely recharge the device. Considering the large battery capacity, this is an acceptable time period.
You should also note that the performance of the CPU and GPU are slightly throttled in battery operation.

Pros
Cons
Verdict - Elegant and with a powerful performance
The Asus ZenBook 13 UM325S is a fast and compact subnotebook with an excellent display. The subnotebook is also light and the modern design is convincing. The selection of high-quality materials make the device not only light, but also very stable. In addition, the visuals and haptics of the device offers a high-quality impression. The AMD Ryzen 7 5800U is a very good fit for the ZenBook 13, ensuring a high performance in the test. However, in terms of the 3D performance, we also notice that the Vega architecture is beginning to hit its limits. With its new Iris Xe Graphics adapters of the Tiger Lake SoCs, Intel is slightly faster here. But since games are not the tasks that are primarily targeted in this device class, the weight of the 3D performance is not on top of our list. As a small refinement, the ClickPad also offers an optional number block.
The Asus ZenBook 13 UM325S is a powerful subnotebook with an AMD Ryzen 7 5800U processor and an excellent display.
We liked the input devices, which should also please frequent typists. The built-in OLED display offers a very good color reproduction. The very low color deviations and very large color space coverage should make the device also interesting for professional image and video processing. While we would have expected slightly more in terms of the battery life, the measured values are appropriate for the device class.
There are only few complaints. The limited selection of connections might become a problem for some users. You are also tied to the current amount of working memory, since this cannot be expanded later. Fortunately, you can at least expand the storage solution if necessary, but there is only space for a single drive. Overall, the Asus ZenBook 13 UM325 leaves a good impression throughout, which is also reflected in the good evaluation result.
