Intelligent Performance

Intel® Core™ Ultra 5 Processor

This laptop is powered by the new Intel® Core™ Ultra 5 225H processor, a powerful chip with 14 cores and 16 threads that can boost up to 4.9 GHz. More importantly, it includes an integrated Intel® AI Boost NPU, a dedicated engine for efficiently handling on-device AI workloads and enabling next-generation AI features in Windows.

Fast Memory and Storage

The processor is paired with 16GB of fast LPDDR5X RAM and a spacious 1TB PCIe 4.0 SSD. This high-speed combination ensures that applications load instantly, files transfer quickly, and multitasking between numerous demanding programs remains incredibly smooth and responsive.

Unrivaled Audio-Visuals

3K 120Hz Lumina OLED Display

The 14-inch ASUS Lumina OLED touchscreen is a class leader, boasting a stunning 3K (2880×1800) resolution and a fluid 120Hz refresh rate. With 100% DCI-P3 color coverage, VESA DisplayHDR True Black 500 certification, and PANTONE® validation, it delivers exceptionally vivid, accurate, and immersive visuals for both creative professionals and media enthusiasts.

Super-Linear Speakers

The audio experience is just as impressive, with new super-linear speakers tuned by Harman Kardon and enhanced with Dolby Atmos®. This system, powered by a Smart Amplifier, produces powerful, crystal-clear, and multi-dimensional sound that punches well above the laptop’s slim form factor.

Premium Portability and Design

Ultra-Slim and Light

The Zenbook 14 OLED is the epitome of portability. Its all-aluminum chassis measures just 1.49 cm thick and weighs a mere 1.28 kg, making it an ideal companion for professionals, students, and travelers who need to work or create from anywhere without being weighed down.

All-Day Battery Life

Despite its slim frame, the laptop houses a large 75Wh extended-life battery. This provides long hours of usage, easily lasting through a full workday or long-haul flight, ensuring you stay productive and entertained without constantly searching for a power outlet.

Seamless Connectivity & Input

Future-Proof I/O

The Zenbook 14 doesn’t compromise on ports. It includes two Thunderbolt™ 4 ports for ultra-fast data transfer, charging, and external displays, alongside a USB-A 3.2 Gen 1 port and a full-size HDMI 2.1 port, eliminating the need for dongles. The inclusion of Wi-Fi 7 ensures the fastest possible wireless speeds.

Intelligent Touchpad

The large, precision touchpad enhances productivity with integrated NumberPad 2.0 support. This innovative feature allows the touchpad to double as an LED-illuminated numeric keypad for rapid data entry, a clever solution for a compact laptop without a physical numpad.
