18-inch QHD+ 240Hz gaming laptop

The MSI Crosshair 18 is an 18-inch gaming laptop built around an Intel Core Ultra 9 275HX processor with 24 cores and a 5.4 GHz max turbo frequency. It pairs that CPU with an NVIDIA GeForce RTX 5070 laptop GPU carrying 8GB of GDDR7 video memory. The 18.0-inch IPS panel runs at 2560 x 1600 resolution and a 240Hz refresh rate. Windows 11 Pro ships pre-installed on a 4TB PCIe SSD backed by 64GB of DDR5 memory.

Who this suits and who should look elsewhere

Creative professionals and competitive gamers who need a large high-refresh screen, 24-thread CPU performance and Thunderbolt 4 connectivity in a single chassis will benefit. Users who prioritise thin-and-light portability or battery life over raw throughput should consider smaller alternatives. The 6.83-pound weight and 1.17-inch profile reflect the cooling required for sustained 5.4 GHz operation.

Deciding specification: 24-core Ultra 9 275HX

The combination of a 24-core Ultra 9 275HX processor and an RTX 5070 8GB GDDR7 GPU determines whether this configuration matches your workload. If your applications scale across 24 threads and demand GDDR7 bandwidth, the balance of compute and graphics memory fits. If you need more video memory or a different CPU tier, a different SKU is required.

Questions about this item

Will the Thunderbolt 4 port support an external 4K display at high refresh rates?

Yes, the USB-C Thunderbolt 4 port includes DisplayPort and Power Delivery 3.0, so it can drive a 4K external monitor while charging the laptop.

Does the 24-core Ultra 9 275HX processor have enough multi-threaded performance for video editing and 3D rendering?

With 24 cores, 24 threads and a 5.4 GHz max turbo frequency, the processor handles heavy multi-threaded workloads such as timeline scrubbing and final renders smoothly.

Is the 4 TB PCIe SSD user-replaceable if I need more capacity later?

The laptop was opened by engineers for the memory and storage upgrade, so the M.2 slot is accessible and the drive can be swapped for a larger PCIe SSD.
