Choosing between the Lenovo Legion 5 Pro and the Lenovo Legion Slim 5i depends on your priorities. The Legion 5 Pro offers slightly better performance for 3D rendering, machine learning, and engineering tasks due to its higher-end graphics card. If gaming or using intensive applications is important, the 5 Pro could be worth the extra investment. However, the Legion Slim 5i, while less powerful, boasts a better balance of features considering its lower price, lighter weight, and significantly longer battery life, making it a strong contender for general use and portability. Both laptops have identical screen size and resolution, storage capacity, and RAM, but if portability and battery life are primary concerns, the Legion Slim 5i has advantages, whereas the Legion 5 Pro stands out for higher-demand computing needs.

The Lenovo Legion Pro 5 has a better screen than the Lenovo Legion Slim 5i for engineering and design, while the Lenovo Legion Slim 5i has a better screen for software development.
When considering screen quality for general use, the Lenovo Legion Pro 5 offers clear visuals and brightness that make it a solid choice for everyday tasks, while the Slim 5i also provides a similar level of quality in this regard, though the Pro 5 may edge ahead in resolution. For engineering and design work, color accuracy and gamut coverage are crucial; hence the Legion Pro 5, with its broader color gamuts, is more suitable than the Slim 5i for professionals who need precise color representation for their workflows. However, for gaming and 3D, the refresh rate becomes paramount for a smooth experience, and unfortunately, both the Legion Pro 5 and Slim 5i fall short in this area, making them less ideal for fast-paced games and rendering 3D animations.

"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."

"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."
