If you prioritize gaming or tasks like 3D rendering, machine learning, and engineering applications, the Lenovo Legion 7 is the stronger option with better performance in these areas due to a more powerful graphics card and processor. However, this laptop is also heavier, pricier, and has a slightly shorter battery life than the Dell Inspiron 16 5620, making the Dell more suitable for general use due to its affordability, longer battery life, and lighter weight. The Dell's performance for general tasks remains competent, with solid build quality and quiet operation. The Lenovo, in contrast, offers better screen quality, keyboard, and a gaming-oriented design with extra features such as RGB lighting and hardware ray tracing. Give Feedback

The Lenovo Legion 7 is good for gaming and AI, while the Dell Inspiron 16 5620 is only fair.
The Dell Inspiron 16 5620, with its integrated Intel graphics, is suitable for less demanding gaming and 3D tasks and offers a standard screen refresh rate, which is less ideal for fast-paced gaming visuals. In contrast, the Lenovo Legion 7 is equipped with a high-performance Nvidia RTX 3070 graphics card and a higher screen refresh rate, making it better suited for intense gaming and 3D applications, with smoother motion and improved visual clarity.

The Lenovo Legion 7 is very good for engineering and design, while the Dell Inspiron 16 5620 is good.
The Lenovo Legion 7 is very good for engineering and design use because it combines a powerful AMD Ryzen 7 CPU and Nvidia RTX 3070 GPU, which makes it capable of handling complex computations and graphics tasks effectively with better screen resolution and quality for detailed work. In contrast, the Dell Inspiron 16 5620, which is merely considered good, offers less robust performance due to its lower-tier Intel CPU and integrated graphics, making it less suitable for demanding engineering software, despite being lighter and more portable.

"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)."

"The Lenovo Legion 7 is a fast 16-inch gamer with 165 Hz display. The new Lenovo Legion 7 is a very good gaming notebook that, despite its comparatively compact compact 16-inch case, does not have to do without the most powerful components. Thanks to good cooling, no compromises are made in terms of performance. Both the Core i9-12900HX and the GeForce RTX 3080 Ti perform at a very high level."
