If you need a laptop with higher performance for tasks like gaming, 3D design, or machine learning, the Lenovo Legion Slim 5i, with its robust graphics card and faster processor, is the better choice. However, if you prefer a machine that is more affordable and suited for everyday tasks and business applications, the Lenovo V15 would suffice. The Legion Slim 5i also offers a higher resolution and refresh rate screen, making it ideal for a premium multimedia experience, but this comes with a heavier build and possibly shorter battery life compared to the more basic and lighter V15. The decision heavily depends on whether the additional power and features are worth the higher cost and less portability when compared to the more budget-friendly V15. Give Feedback

The Lenovo Legion Slim 5i is very good for gaming and AI, while the Lenovo V15 is only fair.
The Lenovo Legion Slim 5i is superior for gaming and 3D applications primarily because it has a high-end Nvidia RTX 4060 GPU and a screen refresh rate of 165Hz, which are very important for smooth and detailed graphics. In contrast, the Lenovo V15 uses the integrated AMD Ryzen 5 5500U Vega 7 graphics and has a lower 60Hz screen refresh rate, which means it offers less graphic power and therefore is less suited for demanding gaming and 3D tasks.

The Lenovo Legion Slim 5i is very good for engineering and design, while the Lenovo V15 is only fair.
The Lenovo Legion Slim 5i is better for engineering and design use due to its higher-performance CPU and GPU, which are crucial for intensive tasks, and it boasts a higher quality screen with better color coverage and resolution. In contrast, the Lenovo V15, while more portable and with a quieter operating noise, has a less powerful CPU and integrated graphics, and lower quality display, hindering performance and visual detail needed for engineering and design work.

The Lenovo Legion Slim 5i has a better screen than the Lenovo V15 for general use, gaming and AI, engineering and design, software development, and content creation.
The Lenovo Legion Slim 5i offers sharper visuals and more vivid colors due to its higher resolution and better panel type, making it suitable for general use and tasks that require color accuracy like engineering and design. However, its refresh rate isn't high enough to satisfy the needs of gaming and 3D applications, where fluid motion is key. The Lenovo V15 falls short on screen quality across the board with lower resolution and inferior panel quality, affecting clarity, color presentation, and brightness—hence it's not ideal for any of the mentioned use cases.

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."

"The strengths of the Lenovo V15 G2 AMD lie in its expandability of the RAM and allowing you to use two SSDs, in its performance that goes beyond everyday applications thanks to AMD's hexa-core CPU and Vega-7 iGPU, in its good keyboard, and its relatively robust case. In addition, the battery life of the office laptop is also acceptable, and the device stays cool and relatively quiet."
