18-inch WQXGA gaming laptop

The ASUS ROG Strix G18 G815LW-G18.U95080-HID5P is an 18-inch gaming laptop built around an Intel Core Ultra 9 275HX 24-core processor and an NVIDIA GeForce RTX 5080 GPU with 16 GB GDDR7 video memory. It ships with 64 GB DDR5 5600 MHz dual-channel memory and a 2 TB M.2 PCIe 4.0 x4 NVMe SSD. The 2560 x 1600 IPS-level display runs at 240 Hz and Windows 11 Pro comes pre-installed.

Verify power adapter and peripheral ports

Confirm that your workspace can accommodate the 15.71 x 11.73 inch footprint and the 0.93 to 1.26 inch height range. The unit weighs 7.54 lbs so ensure your desk or lap surface is stable. Check that your existing peripherals match the available I/O on this chassis and that the supplied power adapter meets the system's requirements for sustained 5.5 GHz turbo operation.

Fits high-performance mobile workflows

The 36 MB L3 cache and 24-thread Arrow Lake architecture handle heavy multitasking while the PCIe 4.0 x4 NVMe drive keeps load times short. Factory-applied Gelid GC Extreme on the GPU and Thermal Grizzly Conductonaut on the CPU lower thermal resistance, freeing headroom for prolonged boost clocks. The 240 Hz panel supports fast-paced competitive titles and colour-critical content creation without external monitors.
