Asus Zenbook 14X OLED pre-production unit review: That's some punchy colors!

Stunning colors, stylish case, great sound The 14-inch laptop from Asus combines a stunning OLED display with a first-class case that is both sturdy and high-quality. Performance should also be great thanks to the MX450 and a Tiger Lake SoC from Intel. Read on to find out what we liked and disliked about the pre-production model.

Asus Zenbook 14X - The elegant subnotebook leaves a good impression on the outside as well as on the inside.
Asus Zenbook 14X - The elegant subnotebook leaves a good impression on the outside as well as on the inside.

Asus has made brightness a top priority for 2021: Many of its laptop series will now be equipped with an OLED display by default. This brings the OLED technology and 3K/4K resolution into the lower price ranges. Mid-range customers will start to seriously consider buying OLED panels now that the difference to devices without OLED is no longer 500 Euros (~$581) but only 200 to 300 Euros (~$232 to ~$349).

That said, Asus doesn't offer mid-range hardware and workmanship with the Zenbook 14X. The chassis has above-average sturdiness and quality. The input devices including the ScreenPad (ClickPad = 2nd display) are first class, and the performance with the Core i7 and the GeForce MX450 is almost top of the line in the subnotebook league.

However, the competition doesn't sleep either and offers a powerful rival in the form of the Dell XPS 13 9310 OLED, for example. Is the only difference the absence of a dGPU? Do we have nothing but praise for the Zenbook 14X, or are there a few points of criticism? Find out in our review.

Case - High-quality laptop

With a thickness of 16.9 mm, the 14-incher is certainly not the thinnest laptop.
With a thickness of 16.9 mm, the 14-incher is certainly not the thinnest laptop.

The case alone is already rather impressive. Asus hasn't gone for the lightest possible case, but in return, it achieves an exceptionally torsion-resistant chassis. The lid can't be pressed in when applying normal force! That is extremely rare - even in the highest-quality subnotebooks. The aluminum back of the lid forms a seemingly indestructible unit with the integrated display panel (non-touch).

The rigorous quality extends to the hinges: The closed position is held magnetically to the base, and the lid can then be opened with one finger. After this, the hinges provide such a firm grip that everything stays in place when carrying or lifting the device.

The base, which is completely made of aluminum, is no different. It can only be pressed in a bit from underneath at certain points. The keyboard doesn't flex at any point, and the base itself is completely firm.

With its 1.4 kg, the Zenbook is among the heavier models. Only the HP Envy 14-eb0010nr exceeds it with 1.6 kg. The difference to the average of the lighter 14-inch and 13-inch devices is 100 grams. However, you receive a sturdier chassis in return. The thinnest model in our comparison is the Dell XPS 13 9310 OLED with 14.8 mm and only 1.2 kg.

Connectivity - Asus device with Thunderbolt 4

Asus provides two Type-C Thunderbolt 4 ports. They can output an image signal (DisplayPort) as well be used to connect the power adapter (100 watts). Including HDMI, three displays can be connected. In practice, however, it will be limited to two if the Type-C charger is used at the same time.

Communication

Wi-Fi module - Soldered

The Intel AX201 Wi-Fi chip is integrated into the device, so it can't be replaced. In our test, the transfer rates are repeatedly clearly below average, so they don't represent what an AX201 is usually capable of. We attribute this to a suboptimal driver configuration in our pre-production sample and expect better results in production models.

Webcam

The webcam in our review sample was unresponsive, and the electronic shutter (orange shutter in front of the camera) didn't respond to the corresponding Fn keys. We presume that this is a pre-production error.

Maintenance

Opening the Zenbook is complicated because of the screws that hide under the rubber feet. Afterwards, the lid can be lifted off easily. However, there's not much to maintain here, since both the Wi-Fi module and RAM are soldered (no socket).

Security

Fingerprint sensor integrated into the power button
Fingerprint sensor integrated into the power button

The power button has a fingerprint sensor that is very inconspicuous: You can log in quickly with the physical sensor, and no space is wasted for a separate fingerprint module. The TPM (Trusted Platform Module) firmware on the motherboard has been standard for a while and is a basic requirement for Windows 11. In some ways, this crypto processor behaves like a permanently installed smart card, but it's tied to the local computer instead of a user.

Warranty

The Zenbook 14X is not available in stores in Germany yet. Asus normally offers a two-year Pickup and Return warranty in Germany.

Input devices - Productive dual display

The matte, non-slip keys have a pronounced pressure point, a moderate travel, and a firm stroke. Typing is almost silent. Working in darker environments is possible thanks to the three-stage white backlight.

Overall, the wide keyboard with its large Shift, Ctrl and directional keys allows the user to type quickly. The spacing between the keys is quite large by laptop standards (2.5 mm). The keyboard's firm base is a very positive aspect. Nothing flexes here at any point.

The keyboard has a solid base throughout its entire area. As a result, the key stroke is firm.

Touchpad

The ClickPad is sensitive up to the edges and offers a short travel. It operates with a dull, quiet noise. The matte surface is quite smooth, but not slippery. It provides a comfortable surface for fingers to glide on. We find the short stroke unsatisfactory, but that's a matter of personal taste.

The pad can turn into a display when desired: The pad function can be used on the fly with an overlay or for longer periods of time by deactivating the display function (Fn+F6).

The ScreenPad 2.0 is matte and has a resolution of Full HD+ (2160x1080). This is an IPS panel. In Windows, the secondary display operates as an extended desktop like any HDMI-connected monitor would. You can drag windows into it such as the Steam app, an editor, or the tools from Photoshop, for example.

Digital signatures take place on the ScreenPad, since the OLED panel is non-touch after all. Asus has preloaded groups on the ScreenPad. Each group can be populated with applications that are useful on the small display: Handwriting, number pad, app store, calculator, or Spotify, for instance.

Display

The main argument for buying the Zenbook 14X is its 14-inch OLED panel. Samsung provides a WQXGA+ panel with 2880x1800 pixels (16:10). With a refresh rate of 90 Hz and a response time of 0.2 milliseconds, the vibrant display outshines any IPS model.

It also promises 100% of the DCI-P3 color gamut, and we can confirm this with our measurements. Asus states that the brightness reaches 500 nits; we measured 381 cd/m² on average and a maximum of 401 cd/m². Nits and cd/m² are converted 1:1, which means that we weren't able to measure the brightness advertised by the manufacturer. Brightness is distributed homogeneously.

High brightness levels are harmful for OLED displays anyway, so they shouldn't be used on a permanent basis. Regarding the issue of burn-in, Asus responds with an OLED screensaver that can't be disabled. It activates after 15 minutes and is important for protecting the panel. According to the manufacturer, users can disable the screensaver after having been informed of the associated risks (warning message). This should be possible via the personal MyAsus Settings (account required). We didn't find an option to turn off the screen saver in the Windows 10 display settings.

The screen-to-body ratio is 92%, which is a very narrow bezel around a lot of display. The Samsung panel makes use of DC dimming to reduce brightness.

Asus has three panel options in its lineup for the Zenbook 14X: the WQXGA+ (2880x1800) non-touch version as in our review unit, the same panel but with touch functionality, and a 4K touch (3840x2400) option. Specifications such as HDR True Black 600, 100% DCI-P3, and a screen-to-body ratio of 92% are identical in all variants.

* ... smaller is better

As one would expect, the OLED display features an outstanding contrast (3,790:1); blacks are deep, and colors are vibrant. As typical for OLEDs, the response times are also excellent. PWM for brightness reduction sets in at brightness levels of 50% and below, making the display flicker at a frequency of 362 Hz. Sensitive users might be affected by this, although we rarely adjusted brightness below 50% in practice. In normal office usage in daylight, we operated at 60-70%.

We measured the grayscale and color DeltaE values before calibration at 2.4 and 2.3, respectively - very good values as they are below 3.0. Calibration improved grayscales a bit (1.8), but colors became worse (2.4). In short: You can skip calibration, because the factory-calibrated panel can't be improved.

The glossy surface (non-touch) suffers from reflections outdoors, and the high brightness doesn't help much here. The panel can be used well in shaded areas, partly also because the brightness doesn't decrease on battery power (379 cd/m² at the center of the display).

Reflections are an issue.

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
2 ms ... rise ↗ and fall ↘ combined↗ 1 ms rise
↘ 1 ms fall
The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 0 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (23.8 ms).
       Response Time 50% Grey to 80% Grey
2 ms ... rise ↗ and fall ↘ combined↗ 1 ms rise

The screen shows very fast response rates in our tests and should be very well suited for fast-paced gaming.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 0 % of all devices are better.
This means that the measured response time is better than the average of all tested devices (37.6 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 not detected ≤ 50 % brightness setting

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 21103 (minimum: 5 - maximum: 3846000) Hz was measured.

There's no question that OLED panels provide the best viewing angles available. Even from flat angles, colors remain stable, and brightness doesn't lose intensity.

The OLED panel looks great from every perspective.

Performance - MX450 with bottlenecks

The cooling system has to make do with a single fan.
The cooling system has to make do with a single fan.

Asus has opted for the Tiger Lake 28-watt Intel Core i7-1165G7 (2.8 GHz) with an integrated Intel Iris Xe G7 graphics card (Gen 12). The latter is complemented by the Nvidia Intel Core i7-1165G7, which can be disabled (Optimus). There will be a variant with the i5-1135G7 (2.4 GHz) for price-conscious buyers, which will also be combined with the MX450. The target group consists of professional users who are looking for a respectable, portable laptop with a high-end display and all-round performance for both work and play.

Processor

The Core i7-1165G7 (2.8 GHz) has a PL1 of 50 watts and a PL2 (short term) of 61 watts. In practice, the processor only operates with 61 watts for seconds, the PL2 value briefly touches the 60-watt mark when Cinebench R15 is run once (100% CPU load). The PL1 value is maintained at 50 watts for a short time only as well, dropping to 28 watts within five seconds. The CPU package consumes an average of 35 watts, with a peak of up to 45 watts at the beginning.

This changes on battery power, where the PL1/PL2 values aren't used at all; the CPU package power consumption briefly scratches the 20-watt mark and then runs at a constant 7 watts. The result: Instead of 951 points, only 284 points (30%) are achieved in the R15 test.

The loop shows that the Zenbook 14X's Turbo stability is suboptimal, which is largely congruent with the other i7-1165G7 devices. As we have often seen, the Ryzen 7 5700U plays in a completely different league in this respect, but its Turbo also weakens after the first run.

In all Cinebench tests, the i7-1165G7 lags behind the Ryzen 7 5700U in multi-core scenarios by a significant margin (-24%). The situation is the other way around in single-core mode, with the i7 leading by a wide margin (+17%). All in all, the SoC's performance is slightly above average compared to other models with the same chipset.

The MX450 installed (Turing TU117M) is the second most powerful variant, the N18S-G5, which offers a 64-bit connection and 1,395 to 1,575 MHz along with GDDR6. It operates with up to 25 watts. Nevertheless, the manufacturer refrains from using a second fan.

  • N18S-G5-B: GBD-128 package, 1,395-1,575 MHz, GDDR6 5,001 MHz, 28.5 W
  • N18S-G5: GB2E-64 package, 1,395-1,575 MHz, GDDR6 5,001 MHz, 25 W
  • N18S-G5: GB2E-64 package, 1,395-1,575 MHz, GDDR5 3,501 MHz, 25 W
  • N18S-LP: GB2E-64 package, 720-930 MHz, GDDR6 5,001 MHz, 12 W

Besides the GeForce MX450 GPU, you also get the integrated Intel Iris Xe 96EUs graphics. The MX450 is at the top in the synthetic benchmarks, and it's on par with the Iris Xe Graphics G7 96EUs or outperforms it by almost 10% in some cases. The MX450 beats the Vega 8 (ZenBook 13 OLED UM325UA) by about 40-50%.

Gaming performance

In the real gaming benchmarks, the MX450 performs moderately. In The Witcher 3 Ultra, the dGPU performs below average: The MSI Modern 14 B11SB-085 and the HP Envy 13-ba1475ng equipped with the same dGPU are about 20% ahead, and even an Iris Xe Graphics G7 96EUs is a tad faster at times (Dell XPS 13 9310 OLED).

The MX450 runs better in Far Cry 5, Strange Brigade, and New World, and it even outperforms an Iris Xe Graphics G7 96EUs by 50% (Strange Brigade). We lack comparison rates in Far Cry 5, but the MX450 performs better than its own average here. The recent New World is still just playable at 32 FPS at Full HD resolution and medium details, but you can't switch to 3K.

We looked at The Witcher 3 in the Ultra setting (Full HD). The FPS keep jumping from 18 to 26 FPS in equal intervals, staying at each level for almost 2 minutes. The video clock rate and temperature increase synchronously following the same cycle. The temperature management apparently allows the dGPU to jump from 1,300 to 1,575 MHz when the temperature drops below 65 °C (~149 °F) for a certain amount of time. The rapid increase in GPU temperatures in turn causes the clock rates to drop in two stages (1,450, 1,250 MHz). Thermals don't seem to work optimally with the single fan and the heat pipes that aren't separated, because we rarely observe such an abrupt increase and decrease of clock speeds.

This seems to be an isolated case, since the thermals and video clock rates don't show any abnormal changes in New World (Medium, Full HD). See Logviewer.
