The Dell Inspiron 14 7425 offers more battery capacity and a touchscreen with a higher resolution and larger aspect ratio, great for productivity tasks and enjoying media. However, the Lenovo IdeaPad Slim 7i has longer battery life, is lighter, and has superior build quality and heat management, making it a better choice for on-the-go use and reliability. Both laptops have similar performance capabilities for general use, but for tasks involving 3D rendering, machine learning, or engineering applications, neither is particularly strong. If portability and build are priorities, go with the Lenovo; if you want a better screen and more versatile input, the Dell is preferable. Give Feedback

The Lenovo IdeaPad Slim 7i and Dell Inspiron 14 7425 are both only fair for gaming and AI.
The Dell Inspiron 14 7425 and the Lenovo IdeaPad Slim 7i are fair for gaming and 3D as both have integrated GPUs which are less powerful than dedicated gaming GPUs and max screen refresh rates of 60Hz which can limit smoothness in fast-paced games. However, the integrated GPUs offer some gaming capability without significantly driving up the cost, and the standard refresh rates contribute to better battery life, making them suitable for casual gaming and general 3D tasks.

Jared Newman | December 2021
"Overall, this Dell Inspiron 14 2-in-1 offers a lot to like, especially at its oft-discounted price of $800. It’s a sturdy laptop with strong performance, a convertible touchscreen, loud speakers, and a convenient fingerprint reader. But the trade-offs you’ll make in pursuit of that lower price—most notably the dim display and stiff trackpad—might just keep you from outright loving it."

"Among Lenovo's multiple laptop brands, the IdeaPad family is decidedly the one designed for consumers: people who want decent performance at a reasonable price. Consider, then, this laptop a paragon for the pickier members of that crowd. With a 14-inch touch-enabled display, a comfortable keyboard, an Evo-certified Intel Core i7 11th Generation CPU, and the latest Windows 11 operating system, the IdeaPad Slim 7i Pro ultraportable ($1,199 as tested) is a slick mainstream machine at a bit of a premium price, and quite capable for everyday tasks."
