For everyday tasks, the Lenovo IdeaPad Slim 3 offers good value with its lower midrange price, ample storage, and decent performance, along with a touchscreen for added convenience. It's also lighter and thinner, making it a better choice for portability. However, if you're looking for a powerhouse that excels in gaming, 3D rendering, and machine learning, the Lenovo Legion Pro 5i (2024) is the way to go. It boasts a high-performance CPU and GPU, a higher resolution display with a faster refresh rate, and better color accuracy, which is great for engineering tasks and intensive gaming. Keep in mind, it's heavier and pricier, but the performance gains are significant for demanding applications. Give Feedback

Olivier Martin, Ryan Lim, and John Peroramas | May 2023
"The Lenovo IdeaPad 3i is decent for use as a workstation. Its Intel CPU and integrated graphics can only handle light productivity tasks, not demanding workloads like video editing or 3D graphics. You also can't do any color-critical work because the available displays have a narrow color gamut. It has a good port selection, but its USB-C lacks Thunderbolt 4 support. On the upside, it has a comfortable keyboard and doesn't get hot or loud under load."

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."
