18-inch WQXGA 240Hz gaming laptop

The ASUS ROG Strix G18 G815LW pairs an 18-inch 2560 x 1600 IPS-level panel at 240 Hz with an Intel Core Ultra 9 275HX 24-core processor and NVIDIA GeForce RTX 5080 graphics. It ships with Windows 11 Pro, 64 GB of DDR5 5600 MHz memory and 8 TB of PCIe 4.0 x4 NVMe storage in Eclipse Gray.

PCIe 4.0 x4 NVMe storage limits

The 8 TB array uses two 4 TB M.2 drives on a PCIe 4.0 x4 interface, so sequential throughput tops out at the 4.0 lane ceiling rather than newer 5.0 speeds. The DDR5 5600 MHz dual-channel kit runs at the platform's rated frequency, and the RTX 5080's 16 GB GDDR7 frame buffer caps VRAM capacity for the largest textures.

Upgrade from lower-tier mobile workstations

Replacing a machine with a previous-generation HX CPU, lesser GPU or smaller SSD yields noticeable gains in compile times, 3D render frames and level-load speed. The jump is worth it when projects exceed 32 GB RAM or 4 TB storage, or when 240 Hz motion clarity matters for competitive play.

Questions about this item

Should I choose the 64 GB DDR5 5600 MHz kit or a smaller capacity?

The laptop ships with 64 GB configured as 2 x 32 GB dual-channel DDR5 5600 MHz, which is the maximum supported capacity for this platform.

What does the 5.5 GHz max turbo frequency mean in daily use?

The 24-core Ultra 9-275HX can boost up to 5.5 GHz on demanding threads, giving strong single-thread speed for games and heavy workloads.

How does the PCIe 4.0 x4 NVMe interface limit the 8 TB SSD in practice?

The 2 x 4 TB drives run at PCIe 4.0 x4 speeds, so sequential reads and writes are capped at the Gen 4 ceiling rather than Gen 5.
