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

In this review the ASUS ROG Strix G18 G815 shows itself as a desktop-replacement gaming laptop aimed at players and content creators who need raw performance and a high-refresh, color-accurate display. The single biggest reason to buy is the combination of an Intel 24-core Ultra 9 275HX and a dedicated NVIDIA GeForce RTX 5060, which together handle modern games and rendering tasks without noticeable slowdowns. The review finds the machine best when used at a desk or on the move by users who prioritize frame rates, multitasking, and large local storage.

Key Features

• Powerful CPU: The Intel 24-core Ultra 9 275HX delivers sustained multi-threaded performance for gaming, streaming and content creation without thermal throttling in typical gaming sessions.
• High-refresh 18in display: The 2.5k 240Hz IPS panel with 100% DCI-P3 and 3ms response gives smooth motion and accurate color for competitive play and color-critical work.
• Ample memory and storage: 32GB of RAM and a 2TB SSD provide fast load times, roomy storage for large game libraries and smooth multitasking.
• Dedicated graphics: The NVIDIA GeForce RTX 5060 8GB handles modern titles at high settings and accelerates creative apps that use GPU compute.
• Comprehensive connectivity: Multiple USB-A 3.2 ports, Thunderbolt 4, USB-C 3.2, HDMI 2.1 FRL and RJ45 let users connect displays, hubs and wired networks without adapters.
• Built-in features for streaming: FHD IR camera, Dolby Atmos and Smart Amp audio simplify live streaming and video calls with clear video and fuller sound.

Who It's For

The ROG Strix G18 suits competitive gamers who want a large, high-refresh display and a powerful processor for high frame rates, and creators who need GPU-accelerated rendering plus a color-capable panel. It is also useful for streamers who benefit from the FHD IR camera and enhanced audio features.

Users who need an ultraportable daily driver or full silence should look elsewhere: this is a performance-first 7.05 lb laptop with a 90Wh battery that prioritizes speed and thermals over extreme mobility or fanless quiet operation.
