The Lenovo Legion 9i, with its high-end price, offers more robust performance due to its Intel i9 processor and Nvidia RTX 4080 graphics, generally outperforming the Legion Slim 7 in tasks like engineering or 3D rendering due to its higher processing and graphics capabilities. However, it's heavier and less portable. In contrast, the Lenovo Legion Slim 7 is typically much less expensive and lighter, making it more portable with still respectable performance using an AMD Ryzen 7 processor and Nvidia RTX 4060 graphics; it's better for general use and some gaming but might not handle intensive tasks as smoothly as the Legion 9i.

The Lenovo Legion 9i has a better screen than the Lenovo Legion Slim 7 for general use, gaming and AI, engineering and design, software development, and content creation.
For general use, the Lenovo Legion 9i's high-resolution display with excellent brightness and color accuracy provides a crisp and vivid visual experience, while for engineering and design tasks, its wide color gamuts ensure that colors are accurately represented. However, for gaming and 3D applications, the Legion 9i's lower refresh rate can lead to less smooth motion. The Legion Slim 7 also offers a high-quality display suitable for general use and precise color work in design, yet like the 9i, its screen falls short for gaming due to the refresh rate, which is crucial for fluid gameplay.

Matthew Buzzi | December 2023
"The Lenovo Legion 9i is meant as a top-end flagship showcase for enthusiasts, and on that, it delivers. You'll find flashier designs in this price tier—Razer’s all-metal build in a similarly sized laptop like the Blade 16, or monstrous 18-inch machines—but this is a well-thought-out laptop. The chassis is trim for a 16-inch powerhouse, the lid is unique, and bespoke liquid cooling takes performance to the next level."

"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
