The ASUS Vivobook S 15 offers a larger storage capacity and a slightly longer battery life which may benefit you if you require ample storage and extended use without charging. It also has a more powerful main processor which is a good fit for more demanding tasks like engineering work, but it is heavier and has a larger form factor which makes it less portable. On the other hand, the Dell Inspiron 14 7420 provides a higher resolution touch screen with a more modern aspect ratio, potentially enhancing your experience while consuming media or performing tasks that benefit from touch input. The Dell is also lighter and offers a potentially better portability due to its smaller screen and physical dimensions. However, it has half the storage capacity of the ASUS and a smaller battery capacity which could limit extended use away from power sources. The choice really hinges on what aspects are more critical for you: higher performance and storage with the ASUS, or better portability and display features with the Dell. Give Feedback

The ASUS Vivobook S 15 and Dell Inspiron 14 7420 are both only fair for gaming and AI.
The ASUS Vivobook S 15 and Dell Inspiron 14 7420 are rated similarly for gaming and 3D tasks primarily because neither laptop has a dedicated high-performance gaming GPU, using instead the integrated AMD Ryzen 7 5800H Vega 8 and Intel i7-1255U Iris Xe graphics respectively. While both can handle some gaming and basic 3D work, neither is optimized for high refresh rates or the most demanding graphics because they lack stronger GPUs and have standard screen refresh rates.

Mario Petzold | February 2023
"Internals make Asus VivoBook S15 laptop a compelling option. The Asus multimedia laptop may look rather below-average with its modest black chassis, lack of a dedicated GPU, limited RAM and meagre port selection without Thunderbolt support. But your impression of the device will start changing once you set your eyes on its high-contrast OLED capable of producing deep blacks and highly accurate colours. And your opinion will change completely when the VivoBook is switched on. The AMD CPU can effortlessly keep up with powerful rivals from Intel. The integrated Radeon graphics blows away Intel's iGPU when it comes to graphics workloads such as rendering and simpler games."

"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."
