The ASUS Vivobook S 15 offers better general use and engineering performance, with higher storage capacity and larger screen size, making it a better fit for tasks that demand more space and processing power. However, the Zenbook Duo 14 features a touchscreen, better color coverage, and more advanced port options like Thunderbolt 4, making it ideal for creative professionals who prioritize display quality and connectivity. The Zenbook is also more portable due to its smaller size and lighter weight, and offers unique features like a second screen, which could enhance multitasking abilities. Ultimately, the choice depends on whether you prioritize performance and storage or portability, display quality, and innovation. Give Feedback

The ASUS Vivobook S 15 and ASUS Zenbook Duo 14 are both only fair for gaming and AI.
The ASUS Vivobook S 15 and ASUS Zenbook Duo 14 are considered fair for gaming and 3D because they have modest GPUs and standard screen refresh rates which limit their ability to smoothly handle high-end gaming and intensive 3D tasks. While the ASUS Vivobook S 15 has an AMD Ryzen GPU and the ASUS Zenbook Duo a slightly better Intel Iris Xe, neither are top-tier for gaming, and both have screens that refresh at a rate that's adequate for general use but not optimal for fast-paced games or 3D rendering.

How the ASUS Vivobook S 15 and the ASUS Zenbook Duo 14 compare to other laptops
"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."
"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."
