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.

How the Lenovo Legion Pro 5i and the Lenovo Legion Slim 7 15.6" compare to other laptops
"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."
