For general use, the Lenovo IdeaPad 5 15" is more budget-friendly, lightweight, and offers longer battery life, making it suitable for tasks like web browsing, document editing, and media consumption. In contrast, the Lenovo Legion Slim 5i is a more robust machine with higher performance for 3D rendering, engineering, or machine learning applications, thanks to its more powerful processor, double the RAM, and superior graphics card. It also boasts a higher-resolution screen, which is better for creative work, but it is heavier and has shorter battery life, making it less ideal for frequent travel. Both have ample ports and a backlit keyboard, but the Legion Slim 5i adds gaming features like ray tracing and a high refresh rate display, appealing for gaming and fast-paced visual tasks.

The Lenovo Legion Slim 5i and Lenovo IdeaPad 5 15" are both good for general use, though the Lenovo Legion Slim 5i is somewhat better.

The Lenovo Legion Slim 5i is very good for engineering and design, while the Lenovo IdeaPad 5 15" is only fair.
The Lenovo IdeaPad 5 15" is fair for engineering and design due to its standard CPU, RAM, and integrated GPU, which may struggle with demanding engineering software, and its screen quality is adequate for general use but less ideal for design tasks which require high color accuracy and resolution. Conversely, the Lenovo Legion Slim 5i is very good for such tasks because it is equipped with a superior CPU, double the RAM, a dedicated high-performance GPU, and a higher resolution screen with better color reproduction, though this also makes it heavier and less portable than the IdeaPad 5.

The Lenovo Legion Slim 5i has a better screen than the Lenovo IdeaPad 5 15" for general use, gaming and AI, engineering and design, content creation, and software development.
The Lenovo IdeaPad 5 15" likely has a screen that's adequate in resolution and brightness for everyday tasks, but it may not cover wider color gamuts essential for precise engineering and design work, and its refresh rate may be too low for smooth gaming and 3D rendering. In contrast, the Lenovo Legion Slim 5i probably features a higher-quality display with better color accuracy to meet the demands of engineering and design professionals, while still delivering a very good viewing experience for general use, although it may also fall short for gaming and 3D with a refresh rate that isn't ideal for these purposes. The lower performance for gaming and 3D in both models can be a deciding factor for users looking for a laptop tailored for high-frame-rate applications.

"The Lenovo IdeaPad 5 is convincing due to its long battery life. The device scores points especially with its large battery and long battery runtimes combined with its low consumption. The CPU and GPU perform in the test as one would expect, and in line with what was familiar from the somewhat smaller 14-inch sister model, the Lenovo IdeaPad 5 14."

Mark Knapp | August 2023
"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."
