If your primary focus is on having higher performance capabilities for tasks like intensive engineering work or multitasking, then the Dell Inspiron 16 5620 could serve you better as it has a more powerful processor and greater memory. However, consider that it is less portable due to a slightly larger size and weight and has a higher price tag. On the other hand, the Lenovo IdeaPad 3 15" is more affordable and offers a level of performance suitable for general use or less demanding tasks. Although it has a lower resolution screen and less optimal graphics, it is lighter, which makes it easier to carry around for everyday mobility. Give Feedback

The Dell Inspiron 16 5620 has a better screen than the Lenovo IdeaPad 3 15" for general use, gaming and AI, engineering and design, software development, and content creation.
For general use, the Dell Inspiron 16 5620 offers a decent combination of resolution and brightness, making text and images clear and visible in various lighting conditions, while the Lenovo IdeaPad 3 15" falls short in clarity and brightness, impacting everyday activities like browsing and document editing. In engineering and design, the Dell's screen covers more color ranges necessary for precision in visual work, whereas the Lenovo's limited color gamut can lead to less accurate color representation. When it comes to 3D and gaming, the Dell's screen lacks the high refresh rate critical for smooth action and rendering motion, and while the Lenovo shares this shortfall, both are further hindered by insufficient resolution and panel quality required for detailed and immersive visuals.

How the Dell Inspiron 16 5620 and the Lenovo IdeaPad 3 15" compare to other laptops
"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 IdeaPad 3 is an enduring office notebook with a powerful Ryzen APU. Lenovo's office all-rounder easily handles office and internet applications as well as modest games - the Ryzen 5 5625U APU and 16 GB of RAM make this possible. The CPU and GPU can work at consistently high clock rates. The emission values are okay, but the noise emissions should be lower under medium to full load. The relatively light notebook (approx. 1.6 kg) achieves practical battery runtimes of about 10 to 11 hours."
