The Dell Inspiron 16 5620 is a budget-friendly option that offers a balance of features for general use with a focus on portability and battery efficiency, suitable for tasks like browsing, office applications, and video streaming. On the other hand, the Lenovo Legion Slim 7 16" is more expensive but provides significantly higher performance, especially for 3D rendering, machine learning, and gaming, due to its more powerful processor and dedicated graphics card. It is heavier and may have a shorter battery life compared to the Dell, but it excels for intensive tasks and has a higher resolution display which is better for detailed work and entertainment. Consider the Dell Inspiron if you value longer battery life and a lighter laptop for everyday tasks at a lower cost, and the Lenovo Legion if you need more power for demanding applications and are willing to invest more.

The Lenovo Legion Slim 7 16" is very good for gaming and AI, while the Dell Inspiron 16 5620 is only fair.
The Lenovo Legion Slim 7 16" excels in gaming and 3D tasks primarily due to its Nvidia RTX 4060 GPU, which provides advanced graphics performance and high screen refresh rate for smooth visuals, whereas the Dell Inspiron 16 5620, although adequate for less demanding games, uses an integrated Intel Iris Xe GPU that's less powerful and a lower screen refresh rate, limiting its ability for intensive gaming and 3D rendering.

The Lenovo Legion Slim 7 has a better screen than the Dell Inspiron 16 5620 for general use, gaming and AI, engineering and design, content creation, and software development.
If you prioritize watching movies, browsing, and office work, the Dell Inspiron 16 5620 with its fair screen will serve you well at a lower price but may not be as crisp as the Lenovo Legion Slim 7 16", which offers superior visuals for both everyday tasks and demanding design work due to its better brightness and resolution. For those into CAD, photo editing, or graphic design, the Lenovo's higher color accuracy makes it a more suitable choice because of its wider color gamut. However, gamers who value smooth visuals in fast-paced games might find both models lacking, as their screens don't have the high refresh rates desired for gaming, coupled with only moderate resolution and panel type.

Brett Venter | January 2023
"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)."

Benjamin Herzig | November 2022
"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
