With an Intel 24-core Ultra 9 275HX and a whopping 64GB of RAM paired with 4TB of SSD storage, the machine targets power users who run demanding games, livestreams, or content creation workflows and want a large, high-refresh 18in display to match. The single biggest reason to buy is raw sustained performance: this laptop combines a top-end CPU, a dedicated GeForce RTX 5060 GPU and a high-bandwidth configuration that keeps heavy workloads moving without compromise.

Who It's For

The ROG Strix G18 is aimed at gamers who prioritize high refresh rates and a large, color-accurate screen, as well as creators who need strong CPU and GPU power in a single portable package.
