18-inch WQXGA 240Hz gaming laptop

This ASUS ROG Strix G18 G815LW pairs an 18-inch WQXGA panel running at 240 Hz with an Intel Core Ultra 9-275HX processor and an NVIDIA GeForce RTX 5080 GPU. It is built for enthusiasts who want desktop-class frame rates on a high-refresh mobile display. The system ships with Windows 11 Home.

32 GB DDR5 and 16 TB PCIe 4.0 NVMe storage

Dual-channel 32 GB DDR5 5600 MHz memory handles heavy multitasking and large texture pools without paging. The 16 TB array (two 8 TB M.2 PCIe 4.0 x4 NVMe SSDs) holds extensive game libraries and project files; capacity runs out only when the combined write volume exceeds the drives' endurance ratings.

Intel Core Ultra 9-275HX 24-core CPU

The Arrow Lake processor delivers 24 cores (8 performance plus 16 efficient) and a 36 MB L3 cache, reaching a maximum turbo frequency of 5.5 GHz. This core count and clock ceiling determine whether the laptop can sustain high frame rates in CPU-bound titles and finish compile or render workloads quickly.
