The Lenovo Legion 5 17" offers a larger screen and is suited for those who prioritize a gaming aesthetic and larger display for immersive gameplay at home, but it is heavier and has lower battery life, which compromises portability. Conversely, the Lenovo Legion Slim 5i is more lightweight, making it easier to carry, and has a longer battery life, thus better for on-the-go use; it also comes with a higher resolution and higher refresh rate display, which is beneficial for both detailed work and entertainment. Choose the Legion Slim 5i for travel and multimedia tasks, and the Legion 5 if gaming performance and screen size are your top priorities. Give Feedback

The Lenovo Legion Slim 5i has a better screen than the Lenovo Legion 5 17" for general use, gaming and AI, engineering and design, content creation, and software development.
The Lenovo Legion 5 17" offers a large, bright display with high resolution which is great for everyday tasks and professional design work, but its slower refresh rate holds it back for gaming and 3D applications.

Both have suitable color accuracy for engineering and design jobs, but enthusiasts in these fields may seek even wider color gamuts for the utmost precision.

"The Lenovo Legion 5 17 is a current-gen 17-inch gaming laptop and equipped with the latest AMD CPU and a powerful GPU, that manages to reach its full potential. The AMD Ryzen 5 5600H is a very good choice for this laptop and able to maintain its performance level for long periods of time. Our test model only falls behind consistently in a direct comparison with its competitors that are often equipped with eight cores and 16 threads. Despite this, the Legion 5 17 leaves an excellent impression and is almost able to keep up with an Nvidia GeForce RTX 3070 mobile GPU in synthetic benchmarks."

"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
