The Dell Inspiron 14 5425 is generally less expensive and boasts a longer battery life, making it a solid choice for general use and portability. It has a smaller, higher-resolution screen with a 16:10 aspect ratio, which can be good for productivity tasks, but it may not be as well-suited for gaming or 3D applications given its integrated Vega 8 graphics. On the other hand, the Lenovo Legion Slim 7 is somewhat more expensive with a larger screen and a higher refresh rate, which, together with its dedicated RTX 3060 graphics card, makes it much better for gaming, 3D rendering, and machine learning. This model has a shorter battery life and is slightly heavier, which might make it less ideal for frequent travel. Both laptops come with the same amount of storage space and RAM, and are equipped with multiple USB-C ports, but the Lenovo has additional RGB keyboard lighting, better suited for gaming enthusiasts.

The Lenovo Legion Slim 7 15.6" is good for gaming and AI, while the Dell Inspiron 14 5425 is only fair.
The Lenovo Legion Slim 7 outperforms the Dell Inspiron 14 5425 in gaming and 3D tasks mainly due to its superior Nvidia RTX 3060 GPU and a higher screen refresh rate, which makes graphics smoother and more detailed. While the Dell comes with an integrated AMD Vega 8 GPU and a standard refresh rate, adequate for casual gaming, the Lenovo's hardware is tailored for more graphically intensive games and applications, delivering better overall performance.

The Lenovo Legion Slim 7 15.6" and Dell Inspiron 14 5425 are both good for engineering and design, though the Lenovo Legion Slim 7 15.6" is somewhat better.
The Dell Inspiron 14 5425 is equipped with an integrated GPU suitable for less demanding engineering and design tasks, along with a solid screen quality, making it beneficial for portability due to its lighter weight and smaller size. On the other hand, the Lenovo Legion Slim 7 15.6" boasts a dedicated high-performance GPU and a display with higher color accuracy and contrast, which makes it better suited for more graphic-intensive engineering and design work, albeit at the cost of being less portable due to its larger size and weight.

The Lenovo Legion Slim 7 has a better screen than the Dell Inspiron 14 5425 for general use, gaming and AI, and engineering and design.
The Dell Inspiron 14 5425 has a panel that provides clear images and adequate brightness, making it suitable for daily tasks like web browsing and video streaming, but its limited color range and lower resolution may not be ideal for precise engineering and design work, and its standard refresh rate isn't suited for the fast-paced visuals required in gaming and 3D applications. The Lenovo Legion Slim 7 offers a higher quality display with better color accuracy and wider color gamut coverage, serving engineering and design needs effectively, yet for gaming, despite its good resolution and panel type, the refresh rate falls short for the most fluid and immersive experience. Both laptops offer satisfactory screen performance for general use, but professionals and gamers should consider these screen characteristics when choosing the right tool for their specific requirements.

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."

"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
