18-inch WQXGA 240Hz gaming laptop

The ASUS ROG Strix G18 G815LW pairs an 18-inch 2560 x 1600 IPS-level panel running at 240 Hz with an Intel Core Ultra 9 275HX processor and NVIDIA GeForce RTX 5080 graphics. Thirty-two gigabytes of DDR5 5600 memory and a four-terabyte PCIe 4.0 NVMe array provide capacity for modern titles and heavy multitasking. The system ships with Windows 11 Home in an Eclipse Gray chassis.

Thermals and acoustics under load

HIDevolution applies Thermal Grizzly Conductonaut liquid metal on the CPU and Gelid GC Extreme on the GPU to lower junction temperatures during sustained workloads. The 24-core Arrow Lake processor reaches a 5.5 GHz max turbo while the RTX 5080 carries 16 GB of GDDR7 video memory. Stress testing validates stable operation before the unit leaves the facility.

Deciding specification — GPU video memory

The sixteen gigabytes of GDDR7 on the RTX 5080 determine whether this laptop can hold the texture working sets of current AAA titles at native WQXGA resolution. If your workflow or gaming library demands more VRAM than 16 GB, a different graphics configuration is required.

この商品に関する質問

How do I install the 4 TB PCIe 4.0 x4 NVMe storage and what step do people get wrong?

The laptop ships with two 2 TB M.2 modules already fitted in the two available slots, so no installation is required. The common mistake is buying a third drive when no free slot remains.

What maintenance will the Gelid GC Extreme thermal compound on the GPU and the Conductonaut on the CPU need later?

Both compounds are designed to last the usable life of the system. No re-application schedule is specified; monitor temperatures and only service if thermals rise noticeably.

What limit appears first during sustained load on the RTX 5080 with 16 GB GDDR7?

The GPU’s 16 GB GDDR7 frame buffer fills before the 32 GB DDR5 5600 system memory becomes a bottleneck in memory-heavy workloads.
