16-inch WQXGA OLED Gaming Laptop

The ASUS ROG Zephyrus G16 GU605CW-XS98-HID5 in Platinum White targets enthusiasts who need desktop-class power in a thin chassis. An Intel Core Ultra 9 285H with 16 cores and 24 MB cache pairs with an NVIDIA GeForce RTX 5080 holding 16 GB GDDR7. The 16.0-inch 2560 x 1600 panel runs at 240 Hz. Sixty-four gigabytes of LPDDR5X at 7467 MT/s and 8 TB of PCIe NVMe storage complete the platform.

Factory-applied thermal upgrades and sealed memory

HIDevolution applies Thermal Grizzly Conductonaut to the CPU and Gelid GC Extreme to the GPU before shipment, lowering operating temperatures under load. The memory is soldered on board in dual-channel configuration, so capacity cannot be changed after purchase. Both M.2 slots are already populated with 4 TB PCIe 4.0 x4 NVMe drives, leaving no free slot for additional internal storage without removing an existing drive.

Platform limits defined by soldered memory

The 64 GB LPDDR5X ceiling is permanent; no SO-DIMM slots exist for expansion. The 240 Hz OLED panel is integrated and does not support external G-Sync variable refresh through the built-in display path. Two M.2 PCIe 4.0 x4 NVMe sockets set the storage interface boundary, and both are occupied in this configuration. Windows 11 Pro is the pre-installed operating system.
