ASUS Zenbook 14 OLED UX3405CA
A 1.28kg Zenbook with a sixteen-core Core Ultra 9 285H, 32GB of memory and a 14-inch WUXGA OLED touchscreen in a 14.9mm chassis.
The Zenbook 14 OLED UX3405CA is the most capable machine in this group and the lightest. Intel's Core Ultra 9 285H brings sixteen cores to a chassis 14.9mm thick that weighs 1.28kg, and 32GB of LPDDR5X sits behind it. It suits people whose work is demanding and whose bag is already full.
The 14-inch WUXGA OLED panel is a touchscreen with a 0.2ms response time, so the interface responds to a finger as well as the touchpad. Two Thunderbolt 4 ports at 40Gbps handle displays, docks and storage, Wi-Fi 7 covers the wireless side, and a 75Wh battery charges over USB Type-C from a 65W adapter.
Ideal For
Sixteen cores running to 5.4GHz with 32GB of LPDDR5X gives room for large datasets, many applications and heavy browser use without the machine reaching its limit.
At 1.28kg and 14.9mm thick with a 75Wh battery and a 65W USB-C charger, both the laptop and its adapter disappear into a bag with room to spare.
The OLED panel accepts touch input, so marking up documents, sketching a diagram or scrolling a long page can be done directly rather than through the touchpad.
Key Features
Sixteen cores and sixteen threads from 2.9GHz to 5.4GHz, the top processor in this chassis, with Intel Arc 140T graphics integrated alongside.
Thirty-two gigabytes is double the usual allocation at this size, and it is what allows large files, virtual desktops and dozens of tabs to coexist.
A WUXGA OLED panel at 1920 x 1200 with a 0.2ms response time and touch input, in a 16:10 shape that suits documents and code.
Both run at 40Gbps with DisplayPort and power delivery, joined by a USB Type-A port and HDMI 2.1, so a dock or monitor connects on one cable.
A uniform 14.9mm profile and 1.28kg on the scales, which is remarkable for a machine carrying a sixteen-core processor and a 75Wh battery.
Tri-band 802.11be wireless in a two-by-two configuration with Bluetooth 5.4, so the machine makes full use of a current router and modern accessories.
Sixteen cores in 14.9mm
The Core Ultra 9 285H is the fastest processor ASUS offers in this chassis, with sixteen cores and a 5.4GHz peak. Putting it in a 14.9mm body that weighs 1.28kg is the interesting part. It means the machine that handles a large export or a heavy compile is the same one that goes into a bag without thought. Thirty-two gigabytes of LPDDR5X keeps those jobs in memory rather than pushing them out to storage.
The OLED touchscreen in practice
This configuration uses the WUXGA OLED panel at 1920 x 1200 with touch input and a 0.2ms response time. Two things follow. The 16:10 shape shows more of a document or a code file than a widescreen panel of the same diagonal, which is where most of the practical benefit sits. And touch turns out to be useful in small ways rather than large ones: scrolling a long page, dismissing a dialogue, marking up a PDF with a finger.
Connections, wireless and charging
Two Thunderbolt 4 ports run at 40Gbps and carry DisplayPort video and power delivery, so a single cable at a desk can drive a monitor, charge the laptop and connect peripherals through a dock. A USB 3.2 Gen 1 Type-A port and HDMI 2.1 cover older hardware. Wireless is Wi-Fi 7 across three bands with Bluetooth 5.4. The 75Wh battery charges from a 65W USB Type-C adapter, so the charger is small enough to travel without complaint.
How It Compares
| What You Need | Technology | Practical Benefit |
|---|---|---|
| Heavy multitasking | 32GB LPDDR5X memory | Dozens of applications and browser tabs stay resident, so switching between them does not force a reload. |
| Processor-intensive work | Sixteen-core Core Ultra 9 285H | Exports, compiles and large batch jobs finish faster than on the four and six-core chips at this weight. |
| Daily commuting | 1.28kg, 14.9mm chassis | One of the lightest ways to carry this much processing power, with a USB-C charger to match. |
| Marking up documents | WUXGA OLED touchscreen | Scrolling, annotating and dismissing dialogues happen by finger without reaching for the touchpad every time. |
| Single-cable desk setup | Thunderbolt 4 at 40Gbps | One connection carries monitor, power and peripherals, so arriving at the desk means plugging in once. |
| Modern home networks | Wi-Fi 7 tri-band | Two-by-two 802.11be wireless takes advantage of a current router across all three available bands. |

The Verdict
Strengths
- Sixteen-core Intel Core Ultra 9 285H processor
- 32GB of LPDDR5X memory as standard
- 14-inch WUXGA OLED touchscreen with 0.2ms response
- 1TB M.2 NVMe PCIe 4.0 solid-state drive
- Two Thunderbolt 4 ports at 40Gbps each
- 1.28kg in a 14.9mm chassis
- Wi-Fi 7 tri-band wireless with Bluetooth 5.4
Considerations
- The 32GB of LPDDR5X is soldered to the board, so the memory cannot be increased at any point later.
- Graphics are integrated Intel Arc 140T, which suits creative work and video rather than demanding 3D gaming.
- This configuration uses the WUXGA OLED panel at 60Hz, not the 3K 120Hz option offered on other Zenbook 14 models.
