For better performance in intensive engineering tasks or gaming, the Lenovo Legion 5i Pro is recommended due to its more powerful processor and graphics card. However, the Lenovo Legion Slim 7 is lighter and offers longer battery life, making it more suitable for portability and general use. If screen resolution is important, the Lenovo Legion 5i Pro provides a higher resolution display, thus better than the Slim 7 for tasks like video editing where screen real estate matters. Consider the Slim 7 if compactness and longer unplugged usage take precedence over raw performance and screen detail. Give Feedback

The Lenovo Legion Pro 5i has a better screen than the Lenovo Legion Slim 7 for general use, gaming and AI, and engineering and design.
The Lenovo Legion Pro 5i's display provides a balance of high resolution and brightness, which enhances the visual experience for general tasks and detailed work required in engineering and design; however, its lower refresh rate hampers the smooth visuals critical for gaming and 3D applications. While the Lenovo Legion Slim 7 also offers a screen that is bright and clear for everyday use and accurate colors for professional design work, it falls short for gaming and 3D modeling due to a refresh rate that's not high enough for those fast-paced environments. Both models excel in providing a crisp and vivid color range for demanding design tasks, but the tradeoff comes with less fluid motion handling needed by gaming and 3D rendering enthusiasts.

PCMag
Brian Westover | August 2023
"The midpriced Lenovo Legion Pro 5i Gen 8 follows some of our favorite gaming machines, including last year's model and the higher-end Legion Pro 7i Gen 8 tested earlier this year. But pedigree doesn't count for much in the computer world, and gaming laptops require a certain level of power and graphics performance to justify their prices. The Pro 5i Gen 8 just doesn't do that, offering middling CPU and GPU performance rather than the sort of muscle that would make it a great value."

"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."
