The ASUS ZenBook UX3405CA-U9321TB represents the pinnacle of premium ultraportable computing, meticulously crafted for discerning users who demand uncompromising performance, sophisticated design, and cutting-edge artificial intelligence capabilities. As a “Copilot+ PC,” this model integrates Intel’s latest and most powerful mobile processor, the Core Ultra 9 285H, with its advanced integrated Intel Arc Graphics, offering a seamlessly intelligent and remarkably efficient user experience for both creative professionals and busy executives on the go.
Detailed Overview
Processor and AI Capabilities: At its core, the ASUS ZenBook UX3405CA-U9321TB is powered by the Intel® Core™ Ultra 9 285H Processor. This is a flagship processor from Intel’s “Lunar Lake” architecture (Core Ultra 200 series), engineered specifically for high-performance in ultraportable form factors, with a strong emphasis on on-device AI acceleration and superior power efficiency. It features an optimized 8-core, 8-thread CPU configuration, comprising 4 high-performance cores and 4 low-power efficient cores, capable of reaching a max turbo frequency of up to 5.1 GHz.
A standout feature is its dedicated Intel AI Boost NPU, which delivers an impressive 67 TOPS (Trillion Operations Per Second). This robust NPU enables the laptop to handle a wide array of “Copilot+ PC” features directly on the device, such as Windows Recall for instant content search, AI-enhanced Windows Studio Effects for superior video calls, real-time Live Captions for audio translation, and creative AI tools like Cocreator, all with exceptional speed and efficiency.
Graphics: Graphics processing is handled by the integrated Intel Arc™ Graphics, specifically the 140V variant. Based on Intel’s innovative Xe² (Battlemage) architecture, this integrated GPU offers significant generational improvements in graphics performance and power efficiency. Beyond traditional graphics rendering, the Intel Arc GPU also plays a crucial role in accelerating AI workloads, contributing to the system’s overall high TOPS capabilities. This ensures a smooth and visually rich experience for multimedia consumption, light content creation, photo editing, and even casual gaming, perfectly complementing the ZenBook’s ultraportable design.
Display: The laptop features a breathtaking 14-inch 2.8K (2880 x 1800) OLED display. This panel is a visual marvel, renowned for its ability to produce incredibly deep blacks, vibrant, true-to-life colors, and an exceptional contrast ratio, making every image and video pop. The 2.8K resolution provides exquisite detail and sharpness, while the 16:10 aspect ratio offers more vertical screen real estate, enhancing productivity for tasks involving documents or web Browse. With a smooth 120Hz refresh rate, users will experience fluid scrolling, seamless animations, and a more responsive feel, which also benefits light gaming.
Furthermore, the display boasts 100% DCI-P3 color gamut coverage, making it an ideal tool for professional content creators who demand precise color representation. It also achieves up to 500 nits (SDR typical) / 600 nits (HDR peak) brightness and carries VESA DisplayHDR True Black 600 certification. For extended comfort, it is TÜV Rheinland-certified for low blue light emissions.
Memory and Storage: The ZenBook UX3405CA-U9321TB is equipped for high responsiveness and ample storage capacity. It comes with 32GB of LPDDR5x RAM, operating at a very high frequency (e.g., 8533 MHz), which is soldered directly onto the motherboard for maximum speed and to contribute to the laptop’s incredibly thin profile. For storage, it includes a generous 1TB PCIe Gen4 NVMe M.2 SSD, ensuring lightning-fast boot times, quick application loading, and abundant space for all essential files, software, and creative projects.
Design and Portability: The ZenBook series is synonymous with a sophisticated and ultraportable design, and the UX3405CA-U9321TB exemplifies this philosophy. Crafted from premium aluminum alloy, the chassis exudes a refined aesthetic while ensuring exceptional durability. It is engineered to be extremely portable, weighing approximately 1.2 kg (2.65 lbs) and boasting an impressive thinness of just 12.9 mm (0.51 inches), making it effortless to carry and use anywhere, from a coffee shop to a boardroom. The minimalist yet elegant design is often highlighted by a Ponder Blue finish.
Keyboard, Audio, and Connectivity: For an optimal user experience, the laptop features a full-size, backlit ErgoSense keyboard with a comfortable 1.4mm key travel, providing an excellent and precise typing experience. A large, responsive ASUS ErgoSense touchpad ensures smooth navigation. The audio system is Harman Kardon-certified with Dolby Atmos support, delivering rich, immersive sound through its stereo speakers, further enhanced by a smart amplifier and AI noise-canceling technology for crystal-clear voice calls.
The Full HD (1080p) IR camera includes AI-enhanced video features, a physical privacy shutter, and supports Windows Hello facial recognition for secure logins. Connectivity is robust with two Thunderbolt™ 4 USB-C® ports (supporting Power Delivery and DisplayPort™ 2.1), one USB 3.2 Gen 1 Type-A port, an HDMI 2.1 (TMDS) output, and a 3.5mm audio combo jack. For wireless connectivity, it features the latest Wi-Fi 7 (802.11be) for ultra-fast and stable connections, alongside Bluetooth® 5.4. A high-capacity 75Wh battery is designed to provide exceptional all-day battery life, complemented by fast-charging capabilities. It runs on Windows 11 Home, fully optimized for the new “Copilot+ PC” functionalities.
