18-inch WQXGA gaming laptop

The ASUS ROG Strix G18 G815LW delivers an 18-inch 2560 x 1600 IPS-level display at 240 Hz in an Eclipse Gray chassis. It runs Windows 11 Pro on an Intel Core Ultra 9 275HX processor with 24 cores and 36 MB cache. The system ships with 32 GB of DDR5 5600 MHz memory and 8 TB of PCIe 4.0 x4 NVMe storage across two 4 TB drives. An NVIDIA GeForce RTX 5080 GPU with 16 GB GDDR7 handles graphics workloads.

NVIDIA GeForce RTX 5080 16 GB GDDR7

The RTX 5080 with 16 GB GDDR7 is the specification that determines whether this laptop meets your performance target. It pairs with the 24-core Ultra 9 275HX reaching 5.5 GHz max turbo to drive the 240 Hz panel at native 2560 x 1600 resolution. Thermal Grizzly Conductonaut on the CPU and Gelid GC Extreme on the GPU are applied to sustain clocks under load. The 8 TB NVMe array provides capacity for large game libraries and content-creation projects.

Build integration and upgrade path

The laptop measures 15.71 x 11.73 x 0.93 to 1.26 inches and weighs 7.54 lbs, so it requires a backpack or sleeve sized for 18-inch devices. Two occupied M.2 slots mean storage expansion needs external drives or drive replacement. Memory slots are filled with the 32 GB DDR5 kit, leaving no room for RAM upgrades without module removal. The 240 Hz WQXGA panel and RTX 5080 combination suits competitive gaming and GPU-accelerated creative workflows on a single portable platform.

Questions about this item

How does the 5.5 GHz turbo frequency behave once the laptop is under sustained load?

The Intel Core Ultra 9 275HX can reach 5.5 GHz max turbo frequency on its 24 cores, with thermal headroom improved by the Conductonaut and Gelid GC Extreme thermal interface materials applied to both CPU and GPU.

What does the PCIe 4.0 x4 NVMe interface mean for the 8 TB of storage in daily use?

The dual 4 TB M.2 SSDs run on a PCIe 4.0 x4 NVMe link, delivering sequential read and write speeds that saturate the Gen 4 bus for fast boot and large-file transfer.

What are the exact dimensions and weight I need to plan for when choosing a bag or desk space?

The chassis measures 15.71 by 11.73 inches with a height ranging from 0.93 to 1.26 inches and weighs 7.54 lbs, so allow at least an 18-inch wide compartment and a sturdy strap.
