The Lenovo Legion 9i 18IAX10 is an 18-inch gaming laptop designed for demanding gaming, content creation, and creative work. Featuring an Intel Core Ultra 9 290HX Plus processor, NVIDIA GeForce RTX 5090 24 GB graphics card, and 64 GB DDR5 memory, it delivers desktop-level performance in a portable form. The 18-inch 4K WQUXGA display (3840 x 2400) covers 100% of the DCI-P3 color space, supports a 240 Hz refresh rate, and comes factory-calibrated with Pantone certification. The chassis is reinforced with machined carbon fiber on the lid and an aluminum frame, making the build sturdy and visually striking.
The Intel Core Ultra 9 290HX Plus processor (24 cores, 24 threads, turbo up to 5.5 GHz) and NVIDIA GeForce RTX 5090 (24 GB GDDR7, 175 W TGP, 1824 AI TOPS) handle heavy gaming, VFX work, 3D rendering, and game development. 64 GB DDR5-5200 memory and a 1 TB PCIe 5.0 x4 NVMe SSD keep latency low during multitasking and large file handling. Four M.2 slots and four SODIMM slots allow for future storage and memory expansion.
The 18-inch WQUXGA IPS display (3840 x 2400) offers 520 nits brightness, 100% DCI-P3 color coverage, and Dolby Vision support. The refresh rate is 240 Hz, and in BIOS HSR mode, it increases to 440 Hz at 1920 x 1200 resolution. G-SYNC and DisplayHDR 400 enhance the gaming experience. The display is Pantone Validated and Pantone SkinTone Validated calibrated, ensuring accurate color reproduction straight from the factory settings.
The LA3-P AI chip and Lenovo AI Engine+ optimize performance, FPS, and cooling in real time based on usage scenarios. The Legion Coldfront Vapor cooling system keeps temperatures under control during long gaming sessions and heavy rendering tasks. AI-based audio synchronization and Fn+Q airflow adjustment provide extra control over ventilation and noise levels.
Two Thunderbolt 5 ports support USB PD 95–100 W charging and DisplayPort 2.1 video output. The HDMI 2.1 port supports up to 8K/60 Hz resolution. Additionally, there are three USB-A 10 Gbps ports (one with Always On charging), one USB-C 10 Gbps port, 2.5 GbE Ethernet (RJ-45), an SD card reader, and a 3.5 mm headphone/microphone jack. Intel Killer Wi-Fi 7 BE1750x and Bluetooth 5.4 handle wireless connections.
The six-speaker audio system (4 bass speakers + 2 tweeters, total 12 W) is optimized with Nahimic Audio technology and a Smart Amplifier. The keyboard features per-key RGB backlighting, allowing each key to be assigned its own color. The 5 MP camera with IR sensor supports Windows Hello facial recognition, and the E-shutter switch covers the camera for privacy protection.
The lid is made of machined carbon fiber and aluminum, with an aluminum base. The 99.9 Wh battery is one of the largest in laptops, and the 400 W power supply ensures sufficient power under full load. The weight is approximately 3.5 kg, and the dimensions are 403 x 296.9 x 23.9–27.95 mm.
