Lenovo Legion 9 18IAX10 Gaming Laptop Intel Core Ultra 9 275HX NVIDIA RTX 5090 24GB

The Ultimate Forged Carbon Flagship

The Legion 9 18IAX10 in its top-tier configuration is Lenovo's most extreme mobile machine, built for game developers, 3D artists, and elite gamers who won't accept limitations. Its Forged Carbon chassis means no two units share the same pattern, and it houses the Intel Core Ultra 9 275HX alongside the flagship NVIDIA GeForce RTX 5090 for a combined 280W of gaming power.

The Intel Core Ultra 9 275HX uses a dedicated AI Boost NPU to optimize complex simulations and creative workflows across its 24 cores. It's paired with 64GB of DDR5 memory and a 2TB PCIe Gen5 NVMe SSD, giving serious headroom for the largest projects and game libraries.

The NVIDIA GeForce RTX 5090 (24GB GDDR7) is Lenovo's flagship mobile GPU, supporting DLSS 4 and real-time ray tracing on the massive 18-inch 4K (3840x2400) Mini-LED display, which runs at 240Hz with 100% DCI-P3 coverage and 540 nits brightness, and can shift to FHD at 440Hz for extreme competitive speed. The Legion Coldfront Vapor cooling system with an AI-tuned triple-fan array keeps the combined CPU/GPU load in check, and dual Thunderbolt 5 ports future-proof its connectivity.
