Today we’re going to take a look at the AMD version of the ASUS ZenBook 14 OLED. It has largely the same specifications as its Intel variant like its 14-inch 2880 x 1800 90Hz OLED touch display, NumberPad, and a premium chassis. Instead of an Intel 12th Generation CPU with LPDDR5, however, the notebook now comes with a Zen 3-based AMD Ryzen CPU and LPDDR4X RAM.

ASUS ZenBook 14 OLED UM3402Y Review – Unboxing

ASUS ZenBook 14 OLED UM3402Y


The ASUS ZenBook 14 OLED UM3402Y does not come much in the way of accessories. Inside the gray-themed ZenBook box is the notebook itself, a 65W USB-C power adapter, and documentation. The notebook does come bundled with a lifetime license for Microsoft Office 2019 Home and Student and 3-months subscription to Adobe Creative Cloud.

Design and Aesthetics

The notebook has a minimalist and premium design as expected from a ZenBook. Instead of the ASUS logo, the ZenBook 14 OLED has the brand’s 30th anniversary logo engraved on its lid. It is much more beautiful compared to just vanilla branding.

Both the lid and the chassis are made out of aluminum. This makes the notebook feel durable while still being lightweight at around 1.39kg. Its 14-inch frame measures at 313.6 x 220.6 x 16.9 and should fit most laptop bags in the market.

Like other entries in the ZenBook range, its ErgoHinge raises the typing angle of the notebook and extends up to 90°. This allows the notebook to lay completely flat on surfaces so information can be easily shared to people across the user.

Display and Audio

ASUS ZenBook 14 OLED UM3402Y

One of the highlights of the ZenBook 14 OLED UM3402Y is its 14-inch 90Hz OLED screen. It is touch-screen compatible but does not come with an anti-glare coating. Bezels are small as expected for this class of device and there is a 1080p webcam with an electronic shutter at the top.

ASUS is promising 100% DCI-P3 coverage and the panel is able to stay pretty close to that at 97.80% DCI-P3 when measured. Colors are great but it seems that the panel prefer green hues and slightly underplays red and blue hues. Contrast is great as expected from an OLED panel and everything looks crisp thanks to its 2880 x 1800 resolution.

  • sRGB – 99.70%
  • Adobe RGB – 91.70%
  • DCI-P3 – 97.80%
  • Luminance (Minimum) – 4.54 cd/m2
  • Luminance (Maximum) – 353.48 cd/m2
  • Delta E (Average) – 0.18
  • Delta E (Maximum) – 1.23
  • Gamma – 2.17
  • Contrast Ratio – 1:1

Brightness is fairly average at around 353.48 cd/m2 it can still be used with backlit environments but display performance might not be optimal while outside. It does not help that it does not come with any anti-glare coating. Brightness uniformity, however, is excellent with only a 2.54% difference between the lowest and brightest portions on the screen.

The notebook has bottom-firing speakers certified by Harman Kardon. The speakers are decent enough with good details and surprisingly punchy bass. Volume isn’t a problem as they can get loud at max volume. Highs, however, don’t have much detail and there’s minimal soundstage on tracks.

Keyboard and Touchpad

The ZenBook 14 OLED UM3402Y sports a 70% chiclet-style keyboard with white backlight. It feels great to type on but the larger keys have some rattle on the stabilizers. Its power button with fingerprint scanner is also oddly located within the keyboard cluster instead of the top-right or away from the keyboard altogether.

The trackpad is large and has a smooth finish for better tracking. It does support gesture controls for seamless browsing on the device. NumberPad 2.0 returns and can be activated by pressing its icon at the top-right of the trackpad. It works well enough for those who need a dedicated number pad and it still allows the trackpad to be used independently.

Input and Output Ports

Most of its ports are located at the right-hand side, which includes two USB 3.2 Gen2 Type-C ports, an HDMI 2.1 port, a 3.5mm audio jack, and a MicroSD card reader. Over at the other side is a single USB 3.2 Gen2 Type-A port.

Its USB-C ports support 65W USB PD charging and DisplayPort connectivity. Unfortunately, they are not Thunderbolt 4 compatible. This means that users will not be able to use external graphics cards on the device.


The notebook comes pre-installed with Windows 11 Home so there’s no need to upgrade from Windows 10. There’s not much in the way of pre-installed software aside from McAfee anti-virus and the usual Microsoft kit like Office apps.

ASUS does include MyASUS, which acts as the command center for the notebook. It can adjust several settings like battery optimization, performance modes, and even monitor system parameters like temperature and clock speeds. The app can also alert you to brand sales and software promos.

ASUS ZenBook 14 OLED UM3402Y Review – Benchmarks

ASUS ZenBook 14 OLED UM3402Y

The ASUS ZenBook 14 OLED UM3402Y comes with a 6-core, 12-thread AMD Ryzen 5 5626U based on the Zen 3 architecture with an AMD Radeon RX Vega 7 GPU. Its CPU is complemented by 8GB of LPDDR4X RAM.

The platform only supports PCIe 3.0 storage and ASUS has opted to use an Intel 600p 512GB NVMe SSD. It is an older model SSD and we expected that it will use something newer, but it still capable in its own right. Sequential Read speeds were able to reach above 1,800MB/s while Sequential Write speeds were set at 1,600MB/s. Performance isn’t mind-blowing but still significantly better than SATA-based storage solutions.

Benchmarks for the ZenBook 14 OLED UM3402Y will include rendering, file compression and decompression, synthetic benchmarks, and some light gaming.

AMD’s Zen 3 architecture still has plenty of mileage as demonstrated by the ZenBook 14 OLED. It consistently places near the top of the chart especially in rendering and other CPU-heavy workloads. It does trail off in memory intensive tasks like file compression and decompression since LPDDR4X is slower than LPDDR5 from newer platforms.

The AMD Radeon RX Vega 7 can get users by in most tasks. It can even handle some light gaming at both 720p and 1080p so long as graphical settings are turned down. Don’t expect the GPU to handle graphically-intensive games, however, as it lacks the horsepower to do so.

Temperature and Battery Life

The notebook has a competent cooling solution despite being in a slim formfactor. The CPU comfortable sits at 43°c when idle and peaks at 92°c when rendering. Despite the relatively high peak temperatures, clock speeds are actually consistent bouncing around 3.2 – 3.4GHz during the run with no throttling.

The Radeon RX Vega 7 is an on-die GPU and share largely the same thermal performance with the CPU. It has a consistent speed of 1.8GHz under graphical load with no throttling even when peaking at 86°c.

The ZenBook 14 OLED UM3402Y runs on a 75Whr Lithium-Ion battery. It can do plenty with it with proper usage. Based on our experience, the notebook will be able to last at around 8 – 10 hours with average use including watching videos over the Internet.

Both USB-C ports support 65W PD Charging. Its 65W power adapter will be able to fill up the battery in around two hours from empty. The notebook can also be charged via USB PD-compatible power banks in the market.

ASUS ZenBook 14 OLED UM3402Y Review – Conclusion

ASUS ZenBook 14 OLED UM3402Y

The ASUS ZenBook 14 OLED UM3402Y still carries the quality that we expect from a ZenBook laptop. It has a beautiful OLED display, decent performance thanks to its AMD Ryzen 5 5625U, and a slim profile perfect for an on-the-go ultraportable.

While the CPU is still top-notch, the platform itself is starting to show its age. LPDDR4x RAM trails behind the performance of LPDDR5 offerings while the lack of Thunderbolt 4 connectivity means that users won’t be able to use external graphics cards.

All-in-all, the ASUS ZenBook 14 OLED UM3402Y is a complete package for those who want to balance price and performance, which is why we are giving it our seal of approval.
