ASUS ROG Strix G18 G815 Gaming AI Laptop - 18in 2.5K 240Hz

In this review the ASUS ROG Strix G18 G815 is positioned as a high-end gaming and content creation laptop for users who need large, fast displays and uncompromising performance. The single biggest reason to buy is its combination of an 18in 2.5K 240Hz IPS-class panel and a top-tier Intel Core Ultra 9 275HX with 24 cores and an on-die AI NPU, which together deliver fluid gaming, fast multitasking, and accelerated AI workloads in a single portable chassis.

Key Features

• Display: The 18in 2.5K Nebula display runs at 240Hz with 3ms response and 100% DCI-P3 color, making games look smooth and colors look accurate for creative work.
• Processor and AI: The Intel Core Ultra 9 275HX offers 24 cores and an integrated NPU up to 13TOPS, which speeds up AI-enhanced features and heavy multithreaded tasks.
• Memory and Storage: With 64GB DDR5 memory and a 2TB SSD the system handles large projects and multiple apps without paging or storage bottlenecks.
• Graphics: NVIDIA GeForce RTX 5060 Laptop GPU with 8GB GDDR7 provides accelerated ray tracing and good performance for 1440p gaming at high settings.
• Connectivity: Thunderbolt 4, USB-C with DisplayPort and power delivery, HDMI 2.1 FRL and Wi-Fi 7 give a full set of modern ports and fast wireless networking.
• Input and Multimedia: A 4-zone RGB backlit keyboard, 1080p IR camera and Dolby Atmos with Smart Amp make the laptop useful for streaming and content creation.

Who It's For

The ROG Strix G18 suits gamers who want a desktop-class experience in a transportable laptop, and creative professionals who benefit from the large 16:10 2.5K display and generous 64GB DDR5 memory for editing, 3D work, or running multiple virtual machines. The integrated NPU is also useful for users experimenting with AI-accelerated workflows and developers who test models on local hardware.

Those who need the absolute lightest ultraportable or the longest battery life should look elsewhere; this is a performance-oriented machine where power and thermals outweigh battery runtime and minimal weight. If you only play casual titles or only need office productivity, the G18 is overkill compared with more compact, lower-powered laptops.
