Introduction
The ASUS ZenBook 13 is a go-to for those who want an extremely compact notebook that they can bring anywhere. Now, though, this mainstream hit has been refreshed with an Oled display for more visual impact and has also been armed with an AMD Ryzen 5000 series mobile processor with Radeon Graphics to deliver uncompromised performance in a thin and light form factor.
Combined with exclusive technologies such as its ErgoLift hinge and NumberPad, the new ZenBook 13 OLED is shaping up to be a tough contender in its category.

Design and Build Quality
ASUS uses an almost similar design language across its ZenBook lineup, and if you put the ZenBook 13 OLED UM325 beside its 14-inch sibling, you’ll only notice a few bits of difference. Measuring at 1.39 cm thin and only weighing slightly more than a Kilo, it will easily fit any standard-sized backpack and takes up even less space on a desk.
The lid is the same ASUS branding on its lid, polished with a premium metal finish. There’s the usual ZenBook branding on its chin, while the gorgeous 13.3-inch Pantone-Validated FHD OLED display is surrounded by slim bezels plus an IR camera up top.
Unlike on the ZenBook 14 where there is a bit of space between the edge of the keyboard and the edge of the laptop, the ZenBook 13 OLED UM325 uses every nook and cranny available to ensure proper spacing between each key.
Speaking of the keyboard, the typing experience is pretty much what you’d expect from this kind of laptop – soft, silent, and short travel time.
Like the ZenBook 14, the power button is placed beside the delete button, which makes it prone to being pressed accidentally. Now, there is, of course, a setting that solves this issue, but you have to remember that some people just buy and use a laptop without a thought of tinkering with the settings.
ZenBook 13 OLED UM325 is equipped with the ErgoLift Hinge, which basically raises the keyboard slightly when the laptop is fully opened, allowing for more natural and comfortable typing. The keyboard is backlit, offering three levels of brightness, while the touchpad can be used as an illuminated calculator for quick calculations (NumberPad) with a press of a button. Like most ASUS laptops I’ve tested, it’s very responsive, and there’s more than enough space for tasks like selecting a large area on the screen.
For ports, you get a single USB Type-A port, a couple of USB-C ports, a microSD card reader, and an HDMI 2.1 port, which means you don’t need to get a dongle to connect to most external displays. There’s no headphone jack, but the laptop comes with a USB-C to 3.5mm dongle.
OLED vs LED LCD
So how exactly does an OLED screen differ from your regular LED LCD? well, an LED LCD uses a backlight to illuminate pixels, while in an OLED screen, each pixel has the capability to produce its own light, which means the light can be controlled more precisely as in you can turn the lighting on each pixel on and off independently. This results in more natural colors and truer blacks.
On the flip side, OLED screens aren’t as bright as LED LCD. Moreover, LED LCDs power consumption only depends on the intensity of the backlight, while OLED is dependent on how bright the screen is and the content that’s on-screen. The more blacks, the less power it needs as it can completely turn off individual pixels.
All this makes OLED screens more expensive to make, that’s why you only usually see them in high-end TVs, smartphones, and in this case, a mainstream laptop. (Sources 1, 2, 3)
Display Analysis
DCI-P3 NTSC sRGB Adobe RGB
The ZenBook 13 OLED UM325S’ screen showcases excellent coverage across all color spaces, which means it’s great for those who are into creative work, as well as for gaming (though it’s not really purpose-built for that).
As expected from an OLED display, the score of 2.2 means you get deep and truer blacks.
On the flip side, the display isn’t showing great consistency across its various levels of brightness. There are huge and different gaps between each brightness level, which means the device isn’t using the same amount of power as the brightness increases.
Performance
The ZenBook 13 OLED UM325S is powered by AMD’s 7nm Ryzen 7 5800U. Utilizing the company’s renowned Zen 3 cores, it delivers 8 cores and 16 threads of processing capability on a 15W TDP paired with AMD Radeon Graphics for a great combo of efficiency and performance needed for everyday productivity and creative tasks.
Compared to its predecessor, this Ryzen 7 5800U is claimed to deliver up to 20 more hours of standby time, up to 3.9 hours more idle time, and up to 1.1 hours more video playback. In total, you get up to 17.5 hours of general use and up to 21 hours of movie playback.
Benchmarks
We put the ZenBook 13 OLED UM325S to a series of benchmarks to determine CPU, GPU, and performance, as well as a few games to see how it’ll fare.
In 3DMark Fire Strike, the Radeon-powered ZenBook 13 OLED trails behind its 14-inch sibling and the Dell Inspiron 14 7400, the former has an NVIDIA GeForce MX450 GPU while the latter has an NVIDIA GeForce MX350.
The Ryzen 7 5800U flexes its muscles at it outperforms both Intel-based notebooks in 3DMark Time Spy.
The ZenBook 13 OLED UM35S continues to shine in Geekbench, coming in between the Intel devices in single-core performance and beating both in multi-core performance.
In both Blender tests, AMD’s processor showcases its prowess, finishing both tests significantly faster than the two Intel-based devices.
