Snapshot

The 30-Second Version

The Zenbook UX3405 is a productivity monster with a gorgeous OLED screen and a top-tier Core Ultra 9 CPU. Integrated graphics are the big compromise, landing in the 14th percentile for GPU performance. Worth buying if you don't game and want serious portable power.

Pros & Cons

Pros

  • Gorgeous 500-nit OLED touchscreen with full DCI-P3 color 90th
  • Core Ultra 9 285H and 32GB RAM crush productivity workloads 83rd
  • Wi-Fi 7 and dual Thunderbolt 4 ports for future-proof connectivity 81st
  • Light 2.82-pound build with a 75Wh battery rated for 18 hours 79th

Cons

  • Integrated Intel Arc graphics are a major bottleneck for gaming
  • 60Hz refresh rate feels dated next to 120Hz OLED rivals
  • No dedicated GPU despite the premium price tag
  • Resealed unit means the SSD was upgraded by a third party, not ASUS

The proof

Performance

The Core Ultra 9 285H is a 16-core beast that lands in the 80th percentile for CPUs in our database. That's well above average, and it shows in everyday multitasking. 32GB of LPDDR5X at 7467MT/s means you can run a dozen Chrome tabs, a code editor, and a video call without breaking a sweat. The 1TB NVMe SSD is also solid, sitting around the 80th percentile for storage speed. The weak spot is graphics. Intel Arc integrated graphics put this at the 14th percentile for GPU performance, so don't expect to play anything beyond light indie titles or older games at low settings. The 60Hz display doesn't help there either, but for productivity, the responsiveness feels snappy.

vs Competition

Stacked against the Apple MacBook Pro M4 Pro, the Zenbook loses on GPU performance, battery consistency, and display refresh rate, but it undercuts the MacBook on price in the US and offers Windows flexibility plus a touchscreen. The HP OMEN Transcend 14 and MSI Raider both bring dedicated GPUs, making them far better for gaming and creative work, though they're heavier and often pricier. The Microsoft Surface Laptop 7th Edition is the closest philosophical match, with a premium build and ARM-based efficiency, but the Zenbook's x86 Core Ultra 9 gives it broader software compatibility. The Lenovo Legion Pro 7i is a different animal entirely, a chunky gaming rig that crushes this in graphics but can't touch the portability.

Value & Pricing

At $1,399 USD, this Zenbook sits in a weird spot. You're paying for the OLED panel, the Core Ultra 9, and that 32GB of RAM, which is a genuinely strong productivity combo. But the integrated graphics hold it back, and the 60Hz screen feels like a compromise at this price. The European and Japanese listings are significantly pricier in their local currencies, which makes the value proposition shakier outside the US. If you need raw CPU power in a portable shell and don't care about gaming, it's a fair deal. If you want any graphical muscle, your money goes further elsewhere.

Overview

The ASUS Zenbook UX3405 is a 14-inch OLED ultraportable that packs a serious CPU punch. You get an Intel Core Ultra 9 285H, 32GB of RAM, and a 1TB SSD in a 2.82-pound chassis. That's a lot of horsepower for a laptop you can toss in a backpack without thinking twice.

The display is the other headline here. A 500-nit OLED touchscreen with 100% DCI-P3 coverage makes everything look rich, and the 16:10 aspect ratio gives you extra vertical room for documents and code. It's not a gaming machine, but for students, developers, and anyone who lives in spreadsheets or a browser, this thing is built to fly.

Common Questions

Q: Can this laptop handle gaming?

Not really. The integrated Intel Arc graphics score in the 14th percentile in our database, so modern AAA titles will struggle even at low settings. Light indie games and older titles are fine, but this is not a gaming laptop.

Q: Is the 60Hz OLED display a dealbreaker?

For productivity, no. The 500-nit brightness and 100% DCI-P3 color make text and media look fantastic. But if you're used to 120Hz or higher on a phone or monitor, you'll notice the difference in smoothness, especially when scrolling.

Q: What does the resealed disclosure mean for warranty?

The laptop was opened to upgrade the SSD by a third-party seller, Issaquah Highlands Tech. That upgraded SSD carries a three-year warranty from the seller, while the rest of the components keep ASUS's one-year manufacturer warranty.

Who Should Skip This

Skip this if you need any real GPU power. Video editors working with 4K footage, 3D modelers, and anyone who wants to play games released in the last five years should look at something with a dedicated graphics card. The 14th percentile GPU score is a hard stop for those use cases. Also skip it if you're outside the US, where the local pricing gets much harder to justify against competitors.

Verdict

Buy this if you're a student, developer, or office pro who wants a fast, light laptop with a stunning OLED screen and doesn't plan to game. The CPU and RAM combo will chew through productivity tasks for years. Skip it if you want to play modern games, edit 4K video with GPU acceleration, or need a high-refresh display. It's a focused tool, not a jack of all trades.
