Some of the best gaming laptops come from Lenovo, like the Legion Pro 7, which we love every time it hits our desks. This time around, it's the bigger brother in the Legion 9i going through its paces, and it's every bit the behemoth that the 18-inch display would indicate. Powered by the fastest laptop components like Arrow Lake HX CPUs and Nvidia's RTX 50-series GPUs, this carbon-fiber bedecked clamshell is ready to race.

This isn't just the unapologetic gaming laptop of its littler brethren; this screams gamer with a carbon fiber lid and RGB lighting. It's got a powerful cooling system to keep thermals in check, a fast refresh rate display, and plenty of power to use every one of those Hz on the display. It's also plagued with the usual gaming laptop issues of limited battery life and low portability, but that's okay if you know that going in.

Price, specs & availability

Lenovo announced the Legion 9i Gen 10 18-inch (2025) in May 2025. A couple of regions got it relatively quickly in June, but it didn't reach the USA until the last part of the year. It had a 4,500 EUR MSRP at launch, though the pricing for US customers starts at $3,920.

All available US models have an Intel Core Ultra 9 275HX CPU, and a choice of Nvidia GeForce RTX 5080 or RTX 5090 dGPU. If you turn all the sliders up to 11, you get 192GB of RAM, the RTX 5090, 4TB of SSD and a 3840x2400 IPS panel with 240Hz refresh rate and Naked-Eye 3D functionality, which is a little like the Nintendo 3DS's glasses-free 3D. Lenovo's pricing is often erratic, but it seems these models haven't changed much since release, and given current component pricing, I'm not entirely sure they will for the near future.

There aren't many competitors for 18-inch laptops, with Asus' ROG Strix G18 and Maingear's Ultima 18 coming to mind immediately. Maingear's option is around the same price, with the ROG Strix G18 a little cheaper but with fewer specification options.

Nothing screams 'gamer' quite like carbon fiber

An understated business laptop, this is not

None of Lenovo's Legion line is particularly understated, and the Legion 9i dials the gamer aesthetic up to 11. Imagine the Legion Pro 7i, just super-sized like at the drive-thru, and then with a new carbon fiber lid atop an anodized magnesium chassis. It's big, bold, and beautiful, if you like that kind of thing. It's built like a tank and weighs about the same: 7.72 lbs without the charger and just over 10 lbs with the charger, so you'll want to invest in a particularly strong backpack if you plan to move it around.

The good news about the robust construction is that you won't be distracted while playing games on the keyboard, because there is zero flex, no weird noises, and no other unwanted issues, and the cooling system keeps the keyboard comfortable. You can open the lid one-handed without it sliding around or moving off the desk, which is a first for me with these oversized laptops.

There's an RGB lightbar at the front, and the whole keyboard is also lit up like the Vegas strip, and don't uninstall the Legion Space app because you'll be unable to control the lighting. Ask me how I know. The power button is brightly lit, showing the active power profile, which then reflects off the bottom of the screen and is far too bright.

You'll want to be looking at the other side of the lid anyway

This is a beautiful display for playing games on

The Legion 9i is decked out for speed, featuring a 16:10 4K IPS panel at 240Hz. It's glossy, but not glass-covered, and doesn't support touch. There's an option for glasses-free 3D, but the review unit I received is the regular IPS option with 500 nits of peak brightness and almost 100% DCI-P3 coverage.

This is about the best IPS panel I've ever used, and it also has G-Sync for silky-smooth frames. Sure, you don't get the deep blacks and instant response time of an OLED, but you also don't have to worry about burn-in or low brightness. You can't get an 18-inch OLED or Mini-LED display, even if you wanted to, so this is the cream of the crop in large gaming laptop displays.

Time to talk about performance

Everything else is secondary in a gaming laptop

Let's get down to brass tacks. The Lenovo Legion 9i is a speed demon. The CPU chews through calculations, and the RTX 5080 mobile is my favorite of the current crop of dGPUs for laptop use. The larger RTX 5090 is often constrained by the CPU or by thermal performance, but the smaller sibling is just right. Even in turbo performance mode, I couldn't get the temperatures high enough to make the keyboard uncomfortable to use, but I did have to put on ANC headphones to protect my ears from the fan noise.

And you'll not want to stop playing games. Even the most demanding titles that I own couldn't stretch the hardware to its limits. Indiana Jones and the Great Circle always has ray tracing, but at 1440p, RT Path Tracing Medium with 4x framegen gave me 277 FPS. It's perhaps disappointing that framegen is necessary to achieve high frame rates in modern games, but the limits of raster performance have been reached, and other rendering pipelines are necessary.

Similarly, Alan Wake 2 is a system crusher, with its intensive ray tracing and beautifully haunting visuals. At 1440p with Ray Tracing High I got an average FPS of 40, but turning framegen on to x4 gave me 144. It's worth mentioning that either setting was smooth, and with the game heavily using upscaling I didn't notice the difference that much between the two modes.

Cyberpunk 2077 is the other main system differentiator, and with 4K and Ultra settings, it averaged 42 FPS. With RT Ultra, DLSS, and 4x framegen, that number shot up to 154 FPS, and was a much more immersive experience in Night City.

It shouldn't surprise anyone that battery life on this model is terrible. Using the Procyon Productivity benchmark, it lasted a paltry one hour and fifty minutes, which is less time than it takes to recharge the battery again. Don't leave home without the 400W charger, because the 140W USB-C charging is barely enough to prevent the Intel CPU from draining the battery, let alone the Nvidia GPU.

It's also worth noting that when Nvidia Optimus is enabled, the system freezes for a second when switching GPU outputs when switching between apps or games that use the RTX 5080. This is annoying but no different to any other gaming laptop using the same system, and I suggest you change the setting to always use the Nvidia GPU. It's not like you'll be leaving the power brick at home, anyway.

Should you buy the Lenovo Legion 9i?

You should buy the Lenovo Legion 9i if:

• You want one of the fastest gaming laptops on the market
• You want to replace your desktop
• You don't mind carrying the heavy power brick around

You should NOT buy the Lenovo Legion 9i if:

• You want long battery life
• You can't live without OLED
• You already have a powerful desktop

Just like its smaller sibling, the Lenovo Legion 9i doesn't care if anyone is watching. It's not quite the heaviest gaming laptop, but it's not far off, and the 18-inch display cuts an imposing figure on anyone's desk. It's not that portable, but it is a true desktop replacement in every sense of the phrase, and doesn't fall into the trap of bad thermal performance when chasing thin-but-powerful gaming options.

If you don't want a desktop PC and a lightweight laptop, this is the dual-use device for you. You won't want to be far away from a power socket, but you'll be able to do anything you would normally do on a powerful desktop PC while still retaining some degree of freedom.
