Our take on the Lenovo Legion 9i 18 4K Gaming Laptop

The Legion 9i 18 is Lenovo's largest and most powerful gaming laptop, pairing an 18-inch 4K display with an Intel Core Ultra 9 275HX and an RTX 5090. It targets players who want desktop-class frame rates and a big screen in one machine, and it competes with 18-inch flagships like the ROG Strix Scar 18 and Alienware m18. Expect strong build and cooling but real weight and fan noise, and 4K gaming at high settings will push the GPU hard.

Questions and answers

Is the Legion 9i 18 good for 4K gaming?
Yes, the RTX 5090 is built for high-resolution play, but 4K at maximum settings in the newest titles still pushes it. Dropping to high settings or using upscaling keeps frame rates smooth.
How does it compare with 16-inch gaming laptops?
It offers a bigger screen and more cooling room than 16-inch models, at the cost of weight and portability. If you rarely move it, the 18-inch size is an advantage.
Can I upgrade the RAM and storage?
It ships with 32 GB DDR5 and a 1 TB SSD. Many Legion laptops allow RAM and SSD upgrades, but check the service manual for this model before buying parts.
Is it good for video editing and 3D work?
Yes. The Core Ultra 9, RTX 5090 and 32 GB of RAM suit editing, rendering and 3D workloads, and the 4K screen helps with detailed timelines.
Does it have Wi-Fi 7?
Yes, it includes Wi-Fi 7 (802.11be), which pairs well with a modern router for lower latency and higher throughput.
What is in the box?
Expect the laptop, its power adapter and standard documentation. Bundled accessories vary, so confirm with the seller if you need extras.
