ASUS has updated the ROG Strix SCAR 18 for 2026, and the spec sheet is not subtle. The new model pairs an Intel Core Ultra 9 290HX Plus processor with up to an NVIDIA GeForce RTX 5090 Laptop GPU, drawing a maximum of 320W of total system power when both components hit full load simultaneously. That puts it at the top of what a consumer gaming laptop can currently deliver.
The display is an 18-inch 4K panel running at 240Hz with a 3ms response time. ASUS is using a Mini LED backlight with ROG Nebula HDR certification, which brings local dimming and higher peak brightness than standard IPS panels at this size. It supports DLSS 4.5 with Multi-Frame Generation, the Blackwell architecture’s primary performance-scaling feature for supported games.
Memory goes up to 64GB of DDR5, with storage configurations reaching 4TB across dual M.2 PCIe Gen 5 slots. The RTX 5090 Laptop GPU carries 24GB of GDDR7 VRAM and 10,496 CUDA cores. ASUS has also updated the thermal system to handle the sustained load — dual fans, liquid metal on the CPU, and five heat pipes on the GPU.
The SCAR 18 2026 was announced at Computex in early June alongside the rest of the ROG lineup for this year. Pricing starts at the high end of the gaming laptop market, consistent with the RTX 5090 configuration. The standard config with an RTX 5080 is available at a lower price point for buyers who don’t need the top GPU.
ASUS is positioning the SCAR 18 2026 as the machine for 4K gaming at high refresh rates with no compromises on sustained performance. For that specific use case, it is currently among the strongest options in the market.
