18-inch WQXGA 240Hz gaming laptop

The ASUS ROG Strix G18 is an 18-inch gaming laptop built around a 2560 x 1600 IPS panel running at 240Hz. It pairs an Intel Core Ultra 9 275HX 24-core processor with an NVIDIA GeForce RTX 5070 laptop GPU carrying 8GB GDDR7 video memory. The system ships with 16GB DDR5 memory and a 1TB PCIe SSD, running Windows 11 Home. It targets users who want a large, high-refresh display in a portable chassis.

Sustained load behaviour

The 24-core processor (8P+16E) reaches a 5.4 GHz turbo frequency, while the RTX 5070 GPU provides 8GB GDDR7 memory for graphics workloads. Under continuous load the chassis must dissipate heat from both the CPU and the discrete GPU simultaneously. The 18.0-inch form factor allows a larger internal volume for airflow, but the 1.4-inch profile limits cooler height. Thunderbolt 4 and USB 3.2 Type-C ports remain available for external docks or storage during extended sessions.

8GB GDDR7 on the RTX 5070 decides VRAM capacity

The single specification that determines whether this configuration fits a workflow is the 8GB GDDR7 video memory on the GeForce RTX 5070. That capacity caps texture pools, frame buffers and compute resources available to the GPU. Buyers working with high-resolution assets, heavy ray-tracing workloads or multi-monitor setups should verify that 8GB meets their minimum requirement before purchase.
