The Dell Inspiron 14 7425 is more expensive but offers better performance, making it suitable for intensive tasks like engineering or 3D modeling, due to its higher-end processor and superior integrated graphics. It also has a higher resolution and more ports, which can be beneficial for multitasking and connectivity. However, despite the slightly smaller screen, it's heavier and has a shorter battery life compared to the Lenovo IdeaPad Slim 3. The IdeaPad Slim 3 is more budget-friendly, but with a larger screen, it's suited for general use, and it boasts a longer battery life, making it more portable. It's less capable for performance-intensive tasks, as it has a lower-tier processor and less RAM. If portability and budget are your top priorities, go for the IdeaPad Slim 3, but if you need a laptop for more demanding work and can handle a higher price and less portability, the Inspiron 14 7425 is a better fit.

Although they have very similar scores, PerfectRec considers Dell Inspiron 14 7425 to be only fair for gaming and AI, while the Lenovo IdeaPad Slim 3 is poor.
The Dell Inspiron 14 7425, with a more powerful Vega 8 GPU, provides better performance for gaming and 3D tasks compared to the Lenovo IdeaPad Slim 3's Vega 6, but both have the same screen refresh rate, which is just adequate for gaming. Additionally, while the Dell model's slightly better screen quality and aspect ratio can enhance the gaming experience, the performance difference is mainly due to the stronger GPU and CPU of the Dell Inspiron 14 7425.

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."

"The Lenovo IdeaPad 3i is decent for use as a workstation. Its Intel CPU and integrated graphics can only handle light productivity tasks, not demanding workloads like video editing or 3D graphics. You also can't do any color-critical work because the available displays have a narrow color gamut. It has a good port selection, but its USB-C lacks Thunderbolt 4 support. On the upside, it has a comfortable keyboard and doesn't get hot or loud under load."
