For general use, the Dell Inspiron 16 5620 is less expensive and offers a larger 16-inch screen with a taller aspect ratio for more vertical content, which is beneficial for productivity tasks like document editing and web browsing. It is lighter, making it more portable. However, if you are involved in more performance-intensive tasks like 3D rendering, machine learning, or gaming, the Lenovo Legion Slim 7 with its powerful AMD processor and Nvidia RTX graphics card will handle these demands better. The Legion Slim 7 also has a higher screen refresh rate, which is great for fast-paced gaming, but it comes at a higher price point and has slightly shorter battery life for typical use compared to the Dell.

The Lenovo Legion Slim 7 has a better screen than the Dell Inspiron 16 5620 for general use, gaming and AI, and engineering and design.
The Dell Inspiron 16 5620's screen, while ample for everyday tasks, may not offer the clarity and vibrancy that users need for detailed engineering work, due in part to its limited color range. The Lenovo Legion Slim 7's display provides better color accuracy and a wider color gamut, making it a more suitable choice for professional design tasks where color fidelity is crucial. However, both laptops have displays with lower refresh rates that are not ideal for gaming or 3D work, where smooth motion and rapid screen updates are key to the experience.

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."
