Performance: Big-Screen High-Refresh Gaming
The Strix G18 is built for performance and capacity. The RTX 5070 Laptop GPU is a strong mobile graphics option, well matched to the laptop’s 2.5K display for high-settings gaming in modern AAA titles, with DLSS 4 and Multi Frame Generation extending frame rates in supported games. The standout is the supporting hardware: a 16-core, 32-thread Ryzen 9 9955HX processor, a generous 64GB of DDR5 memory and a vast 4TB SSD. That combination makes the Strix G18 not just a gaming laptop but a genuine mobile workstation — the memory and storage headroom suit content creation, large game libraries and heavy multitasking far beyond what most gaming laptops offer.

Display: 18-inch 2.5K 240Hz
The defining feature of the Strix G18 is its 18-inch display — a genuinely large screen that makes a real difference for immersion in games and for productivity work. ASUS pairs the size with a 2.5K (2560×1600) resolution and a fast 240Hz refresh rate, so the panel is sharp and smooth as well as big. An 18-inch laptop is a desktop-replacement-class machine, and the display is the main reason to choose it: it delivers a near-desktop viewing experience that 16-inch laptops cannot match.
Design, Build and Cooling
The Strix G18 carries ASUS’s Republic of Gamers design with 4-zone RGB lighting. An 18-inch chassis provides genuine room for cooling, which is an advantage — there is space for larger fans and heatsinks to keep the 16-core CPU and the RTX 5070 within thermal limits during extended sessions. It is, inevitably, a large and heavy laptop; the 18-inch class is the least portable of gaming laptops, and the Strix G18 is best thought of as a transportable desktop replacement rather than a travel machine.
Battery, Portability and Connectivity
The Strix G18 is a desktop-replacement laptop, and that shapes how you use it. It is large and heavy, and like all high-performance gaming laptops it is best gamed plugged in. Its portability advantage over a desktop is real but modest — you can move it between rooms or take it to a LAN event, but it is not a machine for daily commuting. Connectivity covers the modern essentials for external displays, peripherals and fast networking, and the 64GB of RAM plus 4TB SSD mean you will not be reaching for upgrades.

Who Is the ASUS ROG Strix G18 For?
The Strix G18 is for the buyer who wants the largest practical gaming-laptop screen and workstation-grade specifications. If you want an 18-inch display for maximum immersion, value the 64GB of memory and 4TB of storage for content creation or a huge game library, and accept that an 18-inch laptop is a transportable desktop replacement rather than a travel machine, the Strix G18 is squarely your machine. It is not for buyers who prioritise portability, or those on a tight budget. For the gamer-creator who wants a big-screen mobile powerhouse, it is well judged.
Pros and Cons
Pros: Large, immersive 18-inch 2.5K 240Hz display; 16-core Ryzen 9 9955HX; workstation-grade 64GB RAM and 4TB SSD; capable RTX 5070 Laptop GPU; spacious chassis aids cooling.
Cons: Large and heavy; limited portability; premium price; battery life is short under gaming load.
Is the ASUS ROG Strix G18 Worth It?
At $3,257 the ASUS ROG Strix G18 is a strong choice for a specific buyer: someone who wants a big-screen gaming laptop with genuine workstation-grade memory and storage. The 18-inch 2.5K 240Hz display, 64GB of RAM and 4TB SSD are the standout features, and they make the G18 as much a mobile creation machine as a gaming one. The size and weight are the trade-off. For the buyer who wants a big-screen mobile powerhouse, it earns a recommendation. Smaller, more portable options are covered in our best 240Hz gaming laptops guide.
