Choose the Dell Latitude 5431 if a higher battery capacity, better heat management, and a focus on business use are priorities for you. It's also slightly lighter, enhancing portability. Opt for the Lenovo Flex 5 14 if you need more storage right out of the box, prefer a touchscreen with higher resolution, and value longer battery life in more general use. Both laptops offer similar performance for engineering tasks, but the Lenovo's higher color coverage may be advantageous for color-sensitive work. Keep in mind, the Lenovo's slightly larger screen and higher resolution come at the cost of a bit more weight and a slightly larger form factor. Give Feedback

NotebookCheck

Allen Ngo | May 2021
"The highlight of the latest IdeaPad Flex 5 14 is clearly its AMD CPU. The octa-core Ryzen 7 5700U is insanely fast even when compared to the best Tiger Lake Ultrabooks in the market or even Core H CPUs in many gaming laptops. It's a lot of raw processing power for what is supposed to be a budget 14-inch convertible. If your daily workloads can benefit from extra multi-thread CPU performance, then look no further than the inexpensive AMD-powered Lenovo IdeaPad Flex 5 14. For regular on-the-road browsing or video streaming, however, a slimmer and lighter 10th gen Core Yoga, Spectre, or XPS would be a more balanced option."
