MSI Crosshair 18 HX AI gaming laptop 18" QHD+ 240Hz Ultra 9 275HX RTX 5070 64GB 4TB

18-inch QHD+ 240 Hz mobile workstation

The MSI Crosshair 18 HX AI combines an 18.0-inch 2560 x 1600 panel at 240 Hz with an Intel Core Ultra 9 275HX 24-core processor and NVIDIA GeForce RTX 5070 8 GB GDDR7 graphics. Sixty-four gigabytes of DDR5 memory and a 4 TB PCIe SSD provide capacity for large assets. The chassis measures 15.9 x 11.02 x 1.17 inches and weighs 6.83 pounds.

Sustained load on 24-core Ultra 9 and RTX 5070

The 24-core 2.70 GHz Ultra 9 275HX reaches 5.4 GHz turbo across 8 performance cores and 16 efficient cores with 36 MB cache. Thunderbolt 5 and HDMI 2.1 maintain high-bandwidth I/O during long renders. Wi-Fi 6E and RJ-45 keep network streams stable. The 24-zone RGB keyboard remains usable while the cooling system manages continuous CPU and GPU demand.

Upgrade from 16 GB or 1 TB configurations

Builders moving from 16 GB memory and 1 TB storage gain headroom for 4K timelines, virtual machines and texture-heavy engines without external drives. The jump is worth it when project files exceed 50 GB and compile times stall on lesser RAM. Thunderbolt 5 docks add desktop-grade peripherals without cable swaps.
