For general use, the Dell Inspiron 14 5425 offers decent performance with a lower price tag and longer battery life, making it suitable for everyday tasks while being more portable. However, the Lenovo Legion Slim 5, despite being heavier and having a shorter battery life, offers much better performance for intensive tasks like 3D rendering, machine learning, and gaming, thanks to its powerful graphics card. Both have the same screen size and resolution, but the Legion has a higher refresh rate beneficial for fast motion and gaming. The Legion also offers better build quality and thermal management, but because of these features, it usually comes at a slightly higher price. Give Feedback

The Lenovo Legion Slim 5 has a better screen than the Dell Inspiron 14 5425 for general use, gaming and AI, and engineering and design.
For general use, the Dell Inspiron 14 5425 offers a display that is adequate in resolution and brightness, making it suitable for everyday tasks like web browsing and video streaming, but the Lenovo Legion Slim 5, with its higher-quality display, provides a more vibrant and crisp viewing experience. When it comes to engineering and design work, the Lenovo excels due to its wider color gamut coverage, offering more accurate color reproduction for tasks such as photo editing or CAD software, whereas the Dell's color range is more limited in comparison. However, in the context of gaming and 3D applications, both laptops fall short due to their lower refresh rates, which are less than ideal for fast-paced visuals that benefit from smoother motion on displays with higher refresh rates.

Sascha Mölck | August 2022
"A slim chassis, an acceptable weight (1.6 kg) and a real-world battery life of almost 13 hours turn the Inspiron into a mobile companion. Good: The battery can not only be charged using Dell's proprietary power adapter, but also with a universal USB-C power adapter (min. 45 watts). Office and Internet applications are handled by the built-in combination of Ryzen 5 5625U APU and 16 GB of RAM just as easily as modest computer games. Heat and noise development are generally okay, but the laptop should work a bit quieter under full load."

Mark Knapp | August 2023
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
