However, it is heavier, which may affect portability. If price is a concern and you mainly perform basic tasks, the Dell might be more appropriate, while the Lenovo is geared more towards intensive tasks and gaming. Give Feedback

The Lenovo Legion Slim 5 is good for gaming and AI, while the Dell Inspiron 16 5620 is only fair.
The Lenovo Legion Slim 5 outperforms the Dell Inspiron 16 5620 in gaming and 3D applications primarily due to its significantly more powerful Nvidia RTX 4060 graphics card and higher screen refresh rate of 144Hz, compared to the Dell's Intel Iris Xe graphics and a 60Hz screen. While both laptops share the same screen resolution and have similar CPUs which are somewhat important, the GPU and screen refresh rate are very important for gaming and 3D tasks, giving the Lenovo an edge in these areas.

The Lenovo Legion Slim 5 is very good for engineering and design, while the Dell Inspiron 16 5620 is good.
The Lenovo Legion Slim 5 outperforms the Dell Inspiron 16 5620 for engineering and design use primarily due to its more powerful AMD Ryzen processor and superior Nvidia RTX graphics compared to the Dell's Intel i5 processor and integrated graphics, along with a higher screen brightness and refresh rate which contribute to better screen quality. While both laptops offer the same amount of RAM which is crucial for multitasking, the Dell Inspiron is slightly more portable and quieter, but the Legion Slim's superior performance components and screen make it more suitable for demanding engineering tasks and design work.

The Lenovo Legion Slim 5 has a better screen than the Dell Inspiron 16 5620 for general use, gaming and AI, and engineering and design.
The Dell Inspiron's fair screen quality across general use and engineering tasks is due to its adequate resolution and brightness, but its color coverage is limited, resulting in only satisfactory performance for color-intensive tasks. On the other hand, the Lenovo Legion Slim 5, with its good screen quality, offers better resolution and brightness for day-to-day activities and superior color gamut coverage for engineering and design, making it a solid choice for those fields. However, both laptops have screens with poor refresh rates, which holds them back from being ideal for 3D applications and gaming where smooth motion is crucial.

"If the world is exciting enough right now, you can do far worse than a solid performer that you know will get the job done. Our review model is as powerful as you'd want an office machine to be unless you're performing specialist tasks and the price point is pretty attractive (unless work will let you have a MacBook Air instead)."

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."
