The Dell Inspiron 16 5620 is often less expensive and offers good performance for general use, with a decent battery life and portability. Its keyboard is well-regarded, and it maintains a quieter operation. On the other hand, the Lenovo Flex 5 16 costs a bit more but brings a higher resolution touchscreen display, better battery life, and slightly improved performance across general use, 3D machine learning, and engineering tasks. Its keyboard is also backlit with a white color and includes a fingerprint reader for added security. The Flex 5 is slightly heavier, which might impact its portability. Choose the Inspiron for cost savings and quiet use, or the Flex 5 if you require a touchscreen with better display quality and can handle a little extra weight. Give Feedback

The Lenovo Flex 5 16 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 display has a resolution and brightness that meet the needs for general use and productivity tasks, while its color gamut coverage is likely adequate for basic engineering and design work, resulting in fair screen quality for both scenarios. The Lenovo Flex 5 16, with its good screen quality, suggests it provides a higher brightness and possibly a sharper resolution, paired with wider color gamut coverage, meeting the demands for crisp visuals and color accuracy in engineering and design. However, both laptops have displays with poor refresh rates, which are less suitable for Gaming and 3D applications where smoother visuals and faster screen updates are critical.

The Lenovo Flex 5 16 and Dell Inspiron 16 5620 are both only fair for gaming and AI.
The Dell Inspiron 16 5620 and Lenovo Flex 5 16 are both fair for gaming and 3D tasks due to their similar integrated GPUs, which can handle moderate gaming but may struggle with more graphically intensive games or 3D work. The Lenovo Flex 5 16 benefits from a slightly more powerful CPU and higher screen quality, which can contribute to better performance and visuals, but neither has a high refresh rate display that's often preferred for gaming.

How the Dell Inspiron 16 5620 and the Lenovo Flex 5 16 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 Flex 5 is a solidly equipped, 2-in-1 in the lower price segment. Performance is definitely sufficient for everyday tasks and in tests the battery proved itself to be very economical. That aside, there is a lot of standard fare on show and a search for real highlights ends in vain. The low color coverage and reflective display can be avoided by going for an optional 2.5K display but this also presumably results in poorer battery life. The cooling uses only one fan and leads to a raised temperature on one side of the device under load. Additionally, there is very loud fan noise, also under load or when gaming. On top of that, we also occasionally noticed electronic noises."
