Both should handle general use well, but specific needs like graphics-intensive tasks or extended battery life should guide your final decision. Give Feedback

The Lenovo ThinkBook 13x and Dell Inspiron 16 5620 are both good for engineering and design, though the Lenovo ThinkBook 13x is somewhat better.
The Dell Inspiron 16 5620, with its vibrant screen, ample RAM, and dedicated GPU, excels in handling demanding engineering and design software, but it's heavier and might not be as easy to carry around as lighter laptops. On the other hand, the Lenovo ThinkBook 13x, while offering similar CPU and RAM capabilities for efficient multitasking, might have a lesser GPU which could affect graphic-intensive tasks, yet boosts portability and benefits from a high-quality keyboard, making it suitable for on-the-go engineers who prioritize mobility and typing comfort.

The Lenovo ThinkBook 13x 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 crisp text and clear images for everyday tasks, the Lenovo ThinkBook 13x with its high-resolution and bright display, outperforms the Dell Inspiron 16 5620. For engineering and design work, the ThinkBook's wider color coverage ensures more accurate color reproduction, which may be critical for detail-oriented projects. However, neither laptop is ideal for gaming or 3D applications, as both lack high refresh rates that are essential for smooth motion and fast-paced visuals.

The Lenovo ThinkBook 13x and Dell Inspiron 16 5620 are both only fair for gaming and AI.
The Dell Inspiron 16 5620, with a larger screen and high refresh rate, offers a better gaming and 3D experience compared to the Lenovo ThinkBook 13x; however, the ThinkBook 13x, while having a sharper screen, may fall short in refresh rates which can limit its gaming performance. Both laptops come equipped with GPUs that can handle fair gaming and 3D tasks, but the Lenovo's more compact form factor trades away some of that gaming prowess found in the Dell's larger build.

"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)."
