The Lenovo IdeaPad Slim 5i is less expensive and offers good performance for general use, with a lighter weight making it more portable and suitable for carrying around. In contrast, the Lenovo Legion 5 Pro is a higher-end model with superior performance, especially for 3D rendering, machine learning, and intensive gaming, thanks to its more powerful processor and graphics card. However, the Legion 5 Pro is heavier and has a shorter battery life, which might not be as convenient if you frequently travel or work on the go. Consider the IdeaPad Slim 5i for general productivity and everyday tasks, or the Legion 5 Pro if you require high performance for demanding applications and are willing to handle additional weight and shorter battery life.

The Lenovo Legion Pro 5 is very good for gaming and AI, while the Lenovo IdeaPad Slim 5i is only fair.
The Lenovo Legion Pro 5 outshines the IdeaPad Slim 5i for gaming and 3D tasks due to its superior Nvidia RTX 4070 graphics card and higher screen refresh rate, which are crucial for smooth visuals and fast-paced gameplay. In contrast, the IdeaPad Slim 5i is equipped with an Intel i5-1335U Iris Xe graphics card and a lower refresh rate screen, which may suffice for casual gaming but falls short for more demanding 3D applications and gaming experiences.

The Lenovo Legion Pro 5 is very good for engineering and design, while the Lenovo IdeaPad Slim 5i is good.
The Lenovo IdeaPad Slim 5i is geared toward engineering and design with a reliable CPU and integrated graphics, along with a quality screen, but the Lenovo Legion Pro 5 is better suited for even more demanding tasks, sporting a more powerful CPU and a high-end dedicated GPU, coupled with a higher-resolution display, which together provide superior performance and visual clarity for engineering and design applications. While both are reasonably portable, the IdeaPad 5i is lighter and has a longer battery life, which may be preferable for those who prioritize mobility and longer work sessions away from power outlets.

The Lenovo Legion Pro 5 has a better screen than the Lenovo IdeaPad Slim 5i for general use, gaming and AI, engineering and design, content creation, and software development.
The Lenovo IdeaPad Slim 5i, with its fair screen quality, offers a balance of resolution and brightness suitable for everyday tasks but may lack the wide color gamut and high resolution necessary for precise engineering and design work. The Lenovo Legion Pro 5 boasts very good screen quality with a wider color gamut and high resolution that benefits detailed engineering and design tasks, providing richer and more accurate colors. However, both laptops fall short for gaming and 3D applications due to lower refresh rates, which can result in less fluid motion and slower response times during fast-paced activities.

"The device is made for average work loads and if your work has a lot to do with online browsing, using apps that are not power-hungry and streaming videos. The looks are really good and the device in itself is not a heavy one. And with Intel 11th-gen Core processor, you might sail through most of your work without complaints."

Mark Knapp | July 2023
"It doesn't quite match its Legion Pro 7i sibling as an Editors' Choice winner, but Lenovo's AMD-powered Legion Pro 5 Gen 8 is a stylish, well-built gaming laptop with solid performance at both 1080p and its sharper native resolution. It's cheaper than some comparably equipped machines and better than some similarly priced ones. That's a recipe for success, even without its frequent availability of discounts or sales. A brighter screen and longer battery life would be nice, but even as is the Legion Pro 5 earns a solid recommendation."
