The Dell Latitude 5431 is more expensive, and suitable for more intensive tasks with its more powerful processor and better graphics. It has a better build quality and higher resolution screen, which is great for professional use and multitasking. It's also slightly lighter, which is a plus for portability. In contrast, the Lenovo IdeaPad 3 15" is more affordable, and while it has a less powerful processor and lower screen resolution, it remains adequate for everyday activities such as web browsing, office work, and media consumption. It's not as well-suited for heavy-duty tasks and the screen is not as sharp, so it's ideal for general use rather than demanding applications. Choose the Dell if you need performance and quality or the Lenovo if you want to save money and need a laptop for basic tasks. Give Feedback

Sascha Mölck | February 2023
"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."
