For intensive engineering tasks, performance is a priority, and the ASUS Zenbook Duo with its specific processor and GPU provides solid performance, though the Dell Inspiron has more RAM which benefits multitasking and complex projects. If portability is important to you, both models are similar in size and weight, but the ASUS has a slightly longer battery life for extended use away from power sources. The ASUS's dual-screen may enhance productivity, but could also affect battery life. The Dell, with its higher resolution and taller 16:10 aspect ratio display, might be better for reading and web browsing. Both offer a good selection of ports for connectivity. If budget is a concern, the Dell is often a bit less expensive while still offering a high-quality experience. Both are suitable for general use and have decent build quality, but the ASUS is slightly better for gaming due to its higher-quality display features. Consider your specific needs in terms of performance, multitasking, portability, screen quality, and price to make the best choice. Give Feedback

The ASUS Zenbook Duo 14 has a better screen than the Dell Inspiron 14 7420 for general use, gaming and AI, and engineering and design, while the Dell Inspiron 14 7420 has a better screen for content creation.
The ASUS Zenbook Duo 14 offers a high-resolution display and good brightness, making it well-suited for tasks like web browsing, document editing, and watching videos, which are typical in general use. Its strong color accuracy and wide color gamuts cater well to professionals in engineering and design, ensuring that colors are reproduced faithfully. However, for gaming and 3D applications where fluid motion is key, the Zenbook Duo's lower refresh rate could detract from the visual experience, making fast-paced action look less smooth compared to screens designed specifically for gaming.

The Dell Inspiron 14 7420 and ASUS Zenbook Duo 14 are both only fair for gaming and AI.
The ASUS Zenbook Duo 14 and Dell Inspiron 14 7420 have similar Intel Iris Xe graphics, which are decent for light gaming and 3D tasks but may struggle with more demanding graphics-heavy games and software. Both have standard screen refresh rates, which is adequate for casual gaming but may not be as smooth for fast-paced games that benefit from higher refresh rates; the screens are high-quality IPS panels with resolutions that are sharp enough for enjoyable viewing, though not top-tier for gaming where maximum detail is crucial.

How the ASUS Zenbook Duo 14 and the Dell Inspiron 14 7420 compare to other laptops
"The Asus ZenBook Duo's second screen is like the Apple Touch Bar, but better. Most would agree that having two screens instead of one can really boost productivity and the ZenBook Duo is no different in this regard. It's tough going back to just one screen after becoming accustomed to spacious dual-screen setups. For a laptop form factor, however, users will have to accept some compromises. Firstly, weight is the most obvious drawback as the system is several hundred grams heavier than a regular ZenBook 14. Additionally, colors on the second screen will not be as vivid as the main display."
"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."
