16-inch 240 Hz OLED gaming laptop

The ASUS ROG Zephyrus G16 GU605CX is a 16-inch gaming laptop built around a 240 Hz OLED panel. It targets enthusiasts who want a high-refresh display in a compact chassis. The system ships with Windows 11 Home and an Intel Core Ultra 9 285H processor. This configuration suits users who prioritise screen quality and portable performance.

Eclipse Gray aluminium chassis

The laptop measures 13.94" x 9.69" x 0.59" ~ 0.65" and weighs 4.08 lbs in an Eclipse Gray finish. HIDevolution applies Thermal Grizzly Conductonaut on the CPU and Gelid GC Extreme on the GPU during assembly. These thermal-interface upgrades are intended to lower component temperatures under sustained load. The thinner profile and revised cooling paste aim to keep the system stable during extended sessions.

24 GB GDDR7 video memory on the RTX 5090

The discrete NVIDIA GeForce RTX 5090 graphics card includes 24 GB of GDDR7 video memory. This frame-buffer size is the key figure for buyers running high-resolution textures, large 3D scenes or GPU-accelerated workloads. The 32 GB LPDDR5X 7467 system memory and 4 TB PCIe 4.0 x4 NVMe SSD complement the graphics subsystem. Matching this VRAM capacity to your workload determines whether the laptop meets your needs.

Questions about this item

Does the PCIe 4.0 x4 NVMe interface cap the 4 TB SSD at the standard 4.0 lane speed?

The 4 TB M.2 SSD runs on a PCIe 4.0 x4 NVMe link, so its maximum sequential throughput is limited to the 4.0 lane ceiling.

What are the exact chassis dimensions and weight for the GU605CX to confirm it fits my bag?

The laptop measures 13.94" wide, 9.69" deep and 0.59" to 0.65" high, weighing 4.08 lbs.

How is the Thermal Grizzly Conductonaut applied to the CPU, and what step do installers often miss?

The liquid metal is pre-applied between the CPU die and cold plate; the critical step is ensuring the protective barrier around the die is intact to prevent shorting.
