Asus Zenbook 14X OLED: Vibrant display, weak long-term performance

The pre-production unit of the Asus Zenbook 14X impressed us with its 3K OLED display. In terms of performance, the Tiger Lake SoC was always on its toes, but it never really got going under sustained load. Could the single fan be overstrained?

Asus has introduced more color. Many Zenbooks and Vivobooks use colorful OLED displays now and will continue to do so in the future. We recently had a pre-production model of the Asus Zenbook 14X under review. We didn't give the 14-incher a rating due to its lack of a webcam, poor battery life, and some performance issues; we'll do that later with a regular store model.

But this much is true: The Samsung 3K OLED panel looks very good, lacks PWM, and offers a huge color-space coverage. The touchpad's second display is also active in this Zenbook; ScreenPad 2.0 can optionally extend the desktop to the small area. You can now place menus, tools, or players there.

The chassis' workmanship is excellent: The display is firm and of high quality, and the base unit as well. There's no bending or denting here, and the keys have a solid support. The base unit can even be opened to replace the SSD, for example. Unfortunately, there's not much more to do, since the Wi-Fi chip and RAM are soldered.

Continuous load in games or CPU-intensive apps brings the 14X to its limits. Performance throttles faster here than in other Tiger Lake models of the same design. On battery power, performance even drops to 1/4. Due to this being a pre-production model, the results haven't received a rating yet.

You can find all other measurements and tests in our detailed preview of the Asus Zenbook 14X OLED.
