The Dell Inspiron 16 5620 is a budget-friendly laptop that is lighter and has a longer battery life, making it more suitable for general use and portability. It has moderate performance capabilities which are enough for day-to-day tasks or lighter engineering work, and it remains quiet even under load. On the other hand, the Lenovo Legion Slim 5i is more expensive but offers significantly higher performance for 3D rendering, machine learning, and is better suited for intensive gaming due to its advanced graphics card. It also has a higher resolution display which is great for engineering tasks, though it is heavier and might have a shorter battery life. Choose the Dell if you prioritize cost and portability, and the Lenovo if you need high performance for demanding applications and gaming. Give Feedback

When considering general use, the Dell Inspiron 16 5620 provides an adequate experience with its screen resolution and brightness, but falls short compared to the Lenovo Legion Slim 5i, which delivers superior visuals thanks to its higher quality panel that offers better color reproduction and contrast. For engineering and design tasks, where accurate color representation is crucial, the Legion Slim 5i outperforms the Inspiron as its screen covers a wider color gamut, ensuring more precise color matching. However, neither laptop is ideal for 3D tasks and gaming because they lack high refresh rates, which are crucial for smooth motion rendering; the lesser screen quality of these laptops could hinder the immersive experience in fast-paced visual content.

"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."
