Core Ultra 9 275HX 24-core mobile workstation

The MSI Crosshair 18 HX AI is an 18-inch gaming laptop built around an Intel Core Ultra 9 275HX processor with 24 cores and 24 threads reaching 5.4 GHz. It pairs that CPU with an NVIDIA GeForce RTX 5070 graphics card carrying 8GB of GDDR7 memory. The system ships with 64GB of DDR5 5600 RAM and a 2TB PCIe Gen 4x4 NVMe SSD. A 2560 x 1600 IPS panel running at 240 Hz covers 100 percent DCI-P3 colour.

240 W adapter, 90 Whr battery.

A 240 W power adapter feeds the 4-cell 90 Whr battery. One USB-C Thunderbolt 4 port with DisplayPort and Power Delivery 3.0 sits alongside three USB-A 3.2 Gen1 ports, an HDMI 2.1 output, a gigabit RJ45 jack and a combo audio jack. Intel Wi-Fi 6E AX211 and Bluetooth 5.3 handle wireless duties. The 720p webcam includes a physical shutter. SteelSeries 24-zone RGB keyboard with anti-ghosting covers 99 keys.

Desktop-replacement users wanting maximum cores

This configuration suits creators and competitive players who need 24 processing threads, high-refresh 100 percent DCI-P3 visuals and 64GB memory in a single chassis. Buyers prioritising thin-and-light portability or all-day unplugged runtime should look at smaller ultraportables with lower-wattage silicon. The 6.83 lb weight and 1.17 inch profile reflect the cooling and power delivery required for sustained 240 W loads.
