Test Asus ZenBook S 13 Oled : l'ultrabook excellent élève, mais qui réfléchit trop

ZenBook’s new design is successful.


The ZenBook S 13 Oled is Asus’ reference ultrabook. It benefits from a new design that abandons the brushed aluminum lid with concentric circles for a smooth surface with a stylized “A”, all accompanied by an original hinge. Obviously, as its name suggests – and now an Asus trademark – this ZenBook is equipped with an Oled panel to take advantage of the benefits of this technology, namely deep black and impeccable responsiveness.

This new ZenBook is, above all, one of the first ultrabooks on the market to ship an AMD Ryzen 7 6800U engraved at 6nm. If this delicacy of engraving gives you a performance gain and a drop in consumption, we will especially remember that it authorizes the integration by AMD of an RDNA2-type graphics chipset, as in the Radeon RX 6000, instead of the aging Vega architecture .

The ZenBook S 13 Oled is now available from €1,499, accompanied by 16 GB of RAM and 512 GB of SSD.

The chassis of the ZenBook S 13 Oled is made of aluminum and magnesium alloy, which gives it a weight of only 1 kg. Asus has returned to a more conventional design in its 2022 range and our model wears a midnight blue dress and an “A” on the helmet with a selective varnish effect.

The chrome hinge that runs the full width of the PC is obviously part of it, while we notice the side air vent located on the left of the chassis. The set is sober and harmonious. The downside is that the case easily attracts fingerprints and cleaning it with a microfiber cloth is not enough, as our photos show.

The ZenBook S 13 Oled sports a simple and successful design.


A notch on the front of the touchpad lets you grab the screen with one finger; however, opening it will often require the use of both hands. Once the machine is opened, we find the same design as on the outside with a shiny slab (since the screen is touch), not to mention a keyboard with black keys and the number pad equipped with the manufacturer’s NumPad function, which shows a keyboard numeric.

The ZenBook S 13 Oled incorporates the NumPad loved by Asus.


The three-tier backlit keyboard provides nice, well-marked typing. The touch of mise en route is equipped with a Windows Hello compatible digital business reader, which will fully turn on the business of leaving it to connect the user directly to the overture of the Windows session, as if you don’t ‘I was.

The touchpad is a bit difficult to drag and drop. However, it is very pleasant to use with a smooth swipe and Windows gestures are perfectly taken into account.

Most of the connections are on the right hand side; on the left, we identify the air outlet.


The connectivity of the ZenBook S 13 Oled is limited to one connector and three USB-C 3.2 Gen2 ports (10 Gb/s). It is possible to connect a screen using DisplayPort support, or a charger with the Power Delivery protocol. Asus, on the other hand, ignores the HDMI port and the card reader, which is very useful and is present in the ZenBook 14 Oled.

As for wireless connectivity, MediaTek’s AMD RZ616 chip supports Wi-Fi 6E at 2400 Mb/s and Bluetooth 5.2. The integrated 720p webcam offers mediocre rendering, very noisy even in ideal lighting conditions.

Good shine.

Cooling for the Ryzen 7 6800U is provided by a single fan, a heat pipe, and a radiator. Under our thermal camera, the right side of the keyboard heats up to just over 48 °C after coding for 15 min. The keys located above the fan take advantage of the air flow so as not to exceed 36°C. Asus could have limited this heating by increasing the fan speed, which is still relatively inconspicuous with 34.6 dB recorded. Therefore, it will be necessary to play with the cooling modes offered by the MyAsus software to improve this situation, but at the cost of noise pollution.

In Balanced mode, the ZenBook S 13 Oled tends to get hot.


To access the components of the ZenBook S 13 Oled, you need to unscrew nine Torx screws, two of which are hidden under anti-slip pads. The shell then comes off very easily. The SSD, Wi-Fi card and battery are easily accessible and replaceable, only the RAM is soldered to the motherboard. The manufacturer claims a repairability rating of 7.5/10 for this ZenBook S 13 Oled.

The ZenBook S 13 Oled (UM5302TA) is equipped with an AMD Ryzen 7 6800U processor. It is based on the Zen3+ architecture and features a new Radeon 680M graphics chipset derived from the RDNA2 cores of the Radeon RX 6000. The Ryzen 7 6800U features eight 2.7GHz hyper-threaded cores and can occasionally hit 4.7GHz , all with an envelope ranging from 15 to 28 W. Asus has set the limit at 28 W for more performance, but also more heat release, as we have seen.

The Ryzen 7 6800U in the ZenBook S 13 Oled is on a par with the MacBook Air M2.


The ZenBook S 13 Oled gets a performance index of 111 with its Ryzen 7 6800U. It is thus ahead of the MacBook Air M2 which gets an index of 112. It makes it less than the Framework Laptop with its Core i7-1280P, which benefits from the 20 logical cores of its processor for an index of 123, but better than the Core i5-1240P in the Dell XPS 13 Plus which has 16 logical cores, like the Ryzen 7 6800U.

In practice, during our coding on all of its cores, the Ryzen 7 6800U mounted on the ZenBook S 13 Oled runs at 2.66 GHz with a boost of 4.46 GHz and an average envelope of 21 W.

A quick word about the graphics part of the Radeon 680M, as we will have the opportunity to come back to it. we launch Devil 3 in Full HD with all the details to the maximum, and we reached 65 fps. Sure Supervision with details in “high” mode, the ultrabook reaches a maximum of 124 fps. For comparison, this is twice as much as the ZenBook 13 Oled (UM325UA) in Ryzen 5 5500U and its Vega graphics part.

In the game Shadow of the Tomb Raider At 1920 x 1200 pixels, the ZenBook S 13 Oled gets the same number of frames per second as the Apple MacBook Air M2: 16 fps with settings set to “very high.” Switching to the “very low” setting results in 26 fps, which makes the game playable. A good performance for a graphics part integrated in the processor.

Thanks to its integrated Radeon 680M chipset, we are surprised to launch quite a few games.


The SSD of the ZenBook S 13 Oled is a Samsung PM9A1, itself a variant of the 980 Pro. Mounted on the ZenBook, it provides speeds of 3.4 GB/s in reading and writing, far from the 6.9 GB/s in read and 5GB/s write it’s supposed to get, like on the Dell XPS 13 More. However, this will not have any impact on daily use.

Asus has integrated an Oled panel that displays 2880 x 1800 pixels in 16:10 format in this model. The refresh rate is “only” 60 Hz, while the ZenBook 14 Oled took advantage of a 90 Hz version. The panel finish is glossy, it benefits from a touch overlay whose usefulness we find difficult to understand in an ultrabook.

A magnificent screen that only needs an anti-reflection filter to be perfect.


Under our probe, the returned colors turn out to be perfectly accurate with a delta E of 2, well below 3, the threshold from which drifts are visible to the naked eye. Thanks to its panel technology, the ZenBook S 13 Oled displays perfect blacks and impeccable responsiveness. Color temperature is a bit high at 6830K, which is slightly above the 6500K video standard.

The only negative point of this screen, its reflectance measured at 51.7%. The ZenBook S 13 Oled does not appear to be equipped with an anti-reflection filter with an average of 51.7% of the received light being reflected. In practice, when you watch a movie, you will see the keys reflected on the screen during dark scenes; otherwise, the slab will reflect its surroundings, especially near a window. It is not the brightness measured at 375 cd/m² that will change much, and it is generally useless to think about working properly outdoors with the ZenBook S 13 Oled. Note that the panel is HDR compatible and peaks at 567 cd/m². However, you will need to display HDR-compatible content and be connected to mains power to enjoy it.

The sound part of the ZenBook S 13 Oled consists of two speakers located under the chassis. The problem with this integration is sound reproduction. Indeed, the latter depends on the support on which the laptop is placed, and the placement of the hands on the keyboard covers the speakers, thus altering their representation.

Listening, the interpretation is completely banal. Volume is decent, but the entire spectrum is tight around the mids. In the Dolby Access software package that comes with ZenBook, we recommend that you disable all enhancements to enjoy the most neutral sound reproduction possible.

The headphone output offers good characteristics without major flaws, except for this lack of output power. Therefore, headphones with a high impedance should be avoided with this model.

Mobility / Autonomy

The ZenBook S 13 Oled is a true ultrabook for its size, since it is a few millimeters closer to the same dimensions as an A4 sheet (29 x 21 cm) by 1.49 cm thick, all with a weight of a small kilogram. Therefore, it will find its place in your bag without any problem. Its 65W USB-C charging unit weighs just 224g and is easy to transport.

The only thing missing is a detachable cable to make this charger perfect.


Autonomy is the pleasant surprise of this ZenBook S 13 Oled since we reached 11 h 47 min of use in our usual test protocol (Netflix under Chrome, screen configured at 200 cd/m²). With its 67 Wh battery, it is therefore more durable than its 14-inch counterpart, the ZenBook 14 Oled, equipped with an Intel Core i7-1260P. The MacBook Air M2 takes the cake for efficiency with its 52.6 Wh battery.

Charging will take just under an hour and a half to get the ZenBook S 13 Oled back on its feet.
