Looking at the ASUS Zenbook Duo 14 and Lenovo Legion Slim 5i, the Zenbook Duo is more portable and has a slightly longer battery life, making it a good option for on-the-go use and general tasks. It also features a unique dual-screen design, which can boost productivity. However, the Legion Slim 5i offers significantly better performance for demanding tasks like 3D rendering, machine learning, and gaming, thanks to its superior processor and dedicated graphics card. It also has a higher resolution and faster refresh rate display, but it's heavier and has a slightly shorter battery life. If you need top performance and a better screen for specialized tasks, the Legion Slim 5i is the better choice, although it comes with a tradeoff in portability and battery life. Give Feedback

The Lenovo Legion Slim 5i and ASUS Zenbook Duo 14 are both good for general use, though the Lenovo Legion Slim 5i is somewhat better.
The ASUS Zenbook Duo 14's smaller screen size, lower resolution, and less RAM make it fair for general use, along with its lighter weight and slightly better battery life contributing to portability. In contrast, the Lenovo Legion Slim 5i has a larger, higher resolution screen, more RAM, and a higher quality keyboard, making it good for general use, despite being heavier and having slightly shorter battery life.

FAN NOISE SCORE

The Lenovo Legion Slim 5i is very good for gaming and AI, while the ASUS Zenbook Duo 14 is only fair.
The Lenovo Legion Slim 5i is better suited for gaming and 3D applications due to its Nvidia RTX 4060 GPU, which supports hardware ray tracing and DLSS, and a higher screen refresh rate, which is key for smooth, fast-paced visuals. In contrast, the ASUS Zenbook Duo 14 has an integrated GPU with less gaming performance and a standard refresh rate, making it less ideal for gaming, even though it may still handle less demanding tasks reasonably well.

The Lenovo Legion Slim 5i is very good for engineering and design, while the ASUS Zenbook Duo 14 is only fair.
The ASUS Zenbook Duo 14, with an older generation CPU, lower RAM, and an integrated GPU, is suitable for engineering and design tasks but may not handle extremely demanding work as effectively as the Lenovo Legion Slim 5i, which boasts a newer, more powerful CPU, double the RAM, and a dedicated high-end GPU. Moreover, while the Zenbook Duo's dual screen can be helpful for productivity, the Legion Slim offers a larger, higher resolution display that could prove better for intricate design work, despite sacrificing a bit of portability and having a slightly nosier operating environment.

"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."

"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
