18-inch WQXGA 240Hz gaming laptop

The ASUS ROG Strix G18 G815LW is an 18-inch gaming laptop built around a 24-core Intel Core Ultra 9-275HX processor and an NVIDIA GeForce RTX 5080 graphics card with 16 GB GDDR7 memory. It ships with Windows 11 Home, 96 GB of DDR5 5600MHz memory in dual-channel configuration, and 4 TB of PCIe 4.0 x4 NVMe storage across two 2 TB drives. The IPS-level display runs at 2560 x 1600 resolution with a 240 Hz refresh rate.

Who this suits and who should look elsewhere

This machine targets users who need desktop-class multi-threaded performance and high-refresh 2.5K gaming in a single chassis. The 24-core Arrow Lake CPU and 96 GB RAM handle heavy rendering, compilation, and virtualization workloads. Buyers prioritising thin-and-light portability, all-day battery life, or a lower acoustic profile should consider smaller form factors.

Deciding specification: 24-core Ultra 9-275HX

The combination of a 24-core Intel Core Ultra 9-275HX reaching 5.5 GHz max turbo and an RTX 5080 with 16 GB GDDR7 defines the performance ceiling. If your workflow scales across 24 threads and benefits from 16 GB video memory, this configuration fits; if you need fewer cores or less GPU memory, a different SKU will match better.
