16-inch OLED laptop for creators and gamers

The ASUS ROG Zephyrus G16 GU605CW pairs a 16-core Intel Core Ultra 9-285H processor with an NVIDIA GeForce RTX 5080 graphics card. A 16-inch 2.5K 240Hz OLED panel delivers 2560 by 1600 resolution for colour-critical work and fast-paced play. Thirty-two gigabytes of LPDDR5X memory and an 8 TB NVMe SSD provide capacity for large projects and game libraries.

Thermal upgrades and quiet operation

HIDevolution applies Thermal Grizzly Conductonaut on the CPU and Gelid GC Extreme on the GPU to lower core temperatures under sustained load. The 16-core Arrow Lake chip reaches a 5.4 GHz maximum turbo frequency while the RTX 5080 uses 16 GB of GDDR7 video memory. The chassis measures 13.94 by 9.69 by 0.59 to 0.65 inches and weighs 4.08 lbs, allowing a thin profile without sacrificing airflow.

8 TB PCIe 4.0 NVMe storage decides fit

A single 8 TB M.2 PCIe 4.0 x4 NVMe drive handles operating system, applications and media without secondary drives. Windows 11 Pro is pre-installed and validated through burn-in stress testing. The 32 GB LPDDR5X 7467 MT/s memory is soldered, so total system memory cannot be increased after purchase.

Questions about this item

How do I apply the Thermal Grizzly Conductonaut and Gelid GC Extreme upgrades during installation?

These thermal-interface upgrades are already applied by the builder before the laptop ships, so no user installation step is required.

Will the 32 GB LPDDR5X memory or 8 TB NVMe SSD need replacement later?

The LPDDR5X memory is soldered on board and not user-replaceable; the NVMe SSD can be swapped for a larger drive if capacity runs out.

What thermal limit appears first during sustained loads on the Ultra 9-285H and RTX 5080?

The CPU and GPU share a compact vapor-chamber design; under continuous 5.4 GHz turbo the CPU typically hits its thermal ceiling before the GPU.
