The Lenovo Legion Slim 5i is very good for gaming and AI, while the ASUS Vivobook S 15 OLED is only fair.
The Lenovo Legion Slim 5i offers superior gaming and 3D capabilities due to its Nvidia RTX 4060 GPU, which outperforms the integrated graphics on the ASUS Vivobook S 15 OLED, and its higher screen refresh rate to ensure smoother visuals during gameplay. Although both laptops have strong processors and quality displays, the dedicated gaming GPU and the faster refresh rate of the Lenovo are significant for gaming performance and a more fluid interactive experience.

The ASUS Vivobook S 15 OLED has a better screen than the Lenovo Legion Slim 5i for general use, gaming and AI, and engineering and design.
The ASUS Vivobook S 15 OLED boasts vibrant colors and sharp detail due to its high-resolution OLED display, which excels in tasks like photo editing and engineering design applications that rely on accurate color representation. However, the slower refresh rate of the OLED panel isn't ideal for gaming or 3D rendering, which benefit from quick screen refreshes to provide smooth motion. In contrast, the Lenovo Legion Slim 5i, while still offering a high-resolution display with good color accuracy for general and engineering use, falls short for gaming and 3D due to a similarly lower refresh rate.

"The Asus Vivobook S 15 OLED excels as a capable work machine at an affordable price. It offers commendable performance, thanks to its 12th Gen Intel chip, delivers quality on-screen entertainment with its 15.6-inch OLED display, and can (kind of) get you through a full day of work. Oh, and its special Asus Antibacterial Guard is a nice touch for those who like a clean laptop."

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."
