The ASUS Vivobook 15X could be appealing if you value savings and are looking for a basic laptop for everyday tasks like browsing, office applications, and media consumption. It is likely to have lower performance than the more costly Dell Inspiron 14 7420. The Dell will usually offer better performance, which can be important for more intensive computing tasks like video editing, graphic design, or gaming. Consider the size and weight too; larger screens like on the Vivobook may offer a better viewing experience, but the smaller Inspiron can be more portable. Battery life also varies: a laptop with higher performance may have a shorter battery life compared to a less powerful option. Consider what is most important for your use—performance for demanding tasks, battery life for being on the move without charging, or saving money with a capable yet more affordable laptop.

The Dell Inspiron 14 7420 and ASUS Vivobook 15X are both only fair for gaming and AI.
The ASUS Vivobook 15X and the Dell Inspiron 14 7420 are considered fair for gaming and 3D tasks because both have integrated graphics cards, which are typically less powerful than dedicated GPUs for these use cases, and their screen refresh rates are standardized at 60Hz, which is adequate for casual gaming but not optimal for high-refresh-rate gaming experiences. Despite having robust processors, neither laptop specializes in gaming-centric screen quality or GPU performance, making them suitable for general use and moderate gaming, rather than high-end gaming or professional 3D work.

"All in all, my day on the Vivobook had its ups and downs. It is a really pretty and well-built device, and it had all of the functionality I needed to get me through my browser-based workload. But the speakers weren’t my favorite, and the battery life was just too short."

"Notable qualities of the Inspiron 7420 2-in-1 include the 16:10 aspect ratio, strong hinges, 12th gen Intel CPU with optional GeForce MX graphics, and easy serviceability. Such features would typically cost hundreds of dollars more on higher-end alternatives from competing manufacturers. The value proposition is therefore relatively high for users looking to maximize bang for the buck."
