Intel Core Ultra 9 285H Performance
The Core Ultra 9 285H is a 16-core Intel Core Ultra Series 2 processor built for demanding mobile workloads. Its combination of six performance cores, eight efficiency cores and two low-power efficiency cores gives the Zenbook 14 enough processing capacity for heavy browser use, programming environments, large spreadsheets, office applications, photo editing and other multitasking workloads.
The processor can boost to 5.4GHz and includes 24MB of Intel Smart Cache. Performance under long sustained workloads can vary with the laptop’s power mode, temperature and cooling conditions.
ASUS Zenbook 14 UX3405CA Benchmark Reference
Public benchmark results from ASUS Zenbook 14 UX3405CA systems with the Core Ultra 9 285H provide a useful reference for the laptop’s processing and productivity performance.
- Geekbench 6: 2,676 single-core and 15,204 multi-core
- PCMark 10: 7,140 overall score
- PCMark 10 Essentials: 10,266
- PCMark 10 Productivity: 9,178
- PCMark 10 Digital Content Creation: 10,486
Benchmark results vary with BIOS version, drivers, Windows settings, power mode, cooling conditions and background applications, so individual units may produce different scores.
Intel Arc 140T Graphics and AI Performance
The Core Ultra 9 285H includes Intel Arc 140T integrated graphics with 8 Xe cores and a maximum graphics frequency of 2.35GHz. It supports AV1 hardware encoding and decoding, Intel Quick Sync Video and GPU acceleration for compatible creative and media applications.
Intel Arc 140T is suitable for productivity, high-resolution media, creative applications and lighter gaming, but it is not a replacement for a dedicated gaming GPU. Users whose main workloads involve demanding AAA gaming, CUDA applications or heavy professional 3D rendering should consider a laptop with dedicated NVIDIA graphics.
The Intel AI Boost NPU provides up to 13 TOPS for compatible AI workloads, while the complete Core Ultra 9 285H platform reaches up to 99 TOPS across the CPU, GPU and NPU.
2.8K 120Hz ASUS Lumina OLED Display
The 14-inch 2880 × 1800 OLED display uses a 16:10 aspect ratio, providing more vertical workspace for documents, spreadsheets, web pages and development tools. The 120Hz refresh rate also makes scrolling, animations and motion appear smoother than on a standard 60Hz panel.
With 100% DCI-P3 coverage, a 1,000,000:1 contrast ratio, 0.2ms response time and DisplayHDR True Black 600 certification, the panel is well suited to movies, photography, design work and other color-focused content.
32GB Memory and PCIe 4.0 Storage
The 32GB LPDDR5X memory provides enough capacity for heavier multitasking, including multiple browser tabs, office applications, development tools and creative software running together. The memory is soldered to the motherboard, so it is not designed for future RAM upgrades.
SidTech offers 512GB and 1TB PCIe 4.0 NVMe SSD configurations on this product page. Storage uses an M.2 2280 PCIe 4.0 ×4 slot.
Portable Design and 75Wh Battery
At around 1.2kg, the Zenbook 14 UX3405CA is easy to carry between home, office, university and meetings. Its 75Wh battery provides a relatively large battery capacity for a compact 14-inch laptop, while the 65W USB-C adapter allows charging through the Thunderbolt 4 ports.
Ports and Everyday Connectivity
The Zenbook 14 includes two Thunderbolt 4 ports for high-speed data, external displays and USB-C Power Delivery. It also provides USB-A for conventional accessories, HDMI 2.1 for external monitors or TVs and a 3.5mm combination audio jack.
Camera, Privacy and Online Meetings
The FHD camera includes infrared facial recognition for Windows Hello and a physical privacy shutter. A built-in microphone array with AI noise canceling also helps make the laptop practical for online meetings, remote work and virtual classes.
Who Is the ASUS Zenbook 14 UX3405CA For?
