The Lenovo IdeaPad Slim 5i is generally less expensive, lighter, and offers longer battery life, suitable for general use like web browsing, office tasks, and streaming media. However, the Lenovo Legion Slim 7 16" has a better screen resolution, higher refresh rate for smoother visuals, and a more powerful processor and graphics unit, making it ideal for gaming, 3D rendering, and engineering applications. It's slightly heavier and has a slightly shorter battery life, but its performance makes it better for intensive tasks, despite a higher price. If you prioritize portability and price for everyday use, consider the IdeaPad; for higher performance in demanding tasks, the Legion Slim 7 is a better fit. Give Feedback

"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."

Benjamin Herzig | November 2022
"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."
