16" 240 Hz OLED Gaming Laptop

The ASUS ROG Zephyrus G16 GU605CX in Eclipse Gray delivers a 16-inch 2.5K OLED panel at 240 Hz. An Intel Core Ultra 9-285H processor with 16 cores drives the system alongside an NVIDIA GeForce RTX 5090 GPU with 24 GB GDDR7 video memory. It ships with Windows 11 Pro installed.

High-end portable workstation and gaming machine

This configuration suits creators and gamers who need desktop-class graphics and a colour-accurate high-refresh OLED screen in a 4.08 lb chassis. Buyers who require user-replaceable memory or a larger battery should consider alternative designs.

32 GB soldered LPDDR5X-7467 memory

The 32 GB LPDDR5X memory runs at 7467 MT/s in dual-channel mode and is permanently mounted on the motherboard. No SO-DIMM slots are available, so the total system memory cannot be increased after purchase.
