The ASUS Zenbook Duo 14 is usually less expensive and more portable than the Lenovo Legion 9i, which could be important if you often carry your laptop around; however, its performance for intensive tasks and gaming is limited when compared to the Legion 9i. The Lenovo Legion 9i, while usually more expensive and heavier, offers superior performance for gaming, 3D rendering, machine learning, and other engineering tasks. It also has a better battery capacity, screen quality, and higher refresh rate useful in fast-motion scenarios. If requiring high performance for complex tasks is a priority and cost isn't a significant constraint, the Legion 9i stands out. However, if general use and portability are more critical, and the budget is tighter, the Zenbook Duo 14 offers a balanced option. Give Feedback

The Lenovo Legion 9i is very good for general use, while the ASUS Zenbook Duo 14 is good.
The ASUS Zenbook Duo 14, with its moderate RAM and CPU, lighter weight, and better battery life, is fair for general use but lacks the substantial performance of the Lenovo Legion 9i, which boasts a powerful CPU, ample RAM, and a high-quality screen, though it is less portable and has shorter battery life. The Zenbook Duo's portability makes it suitable for on-the-go tasks, while the Legion's features cater to more demanding applications despite its reduced mobility and battery duration.

The Lenovo Legion 9i is excellent for gaming and AI, while the ASUS Zenbook Duo 14 is only fair.
The Lenovo Legion 9i stands out for gaming and 3D tasks with its Nvidia RTX 4080 GPU and a high 165Hz screen refresh rate, over the ASUS Zenbook Duo 14's built-in Iris Xe graphics and a standard 60Hz screen refresh rate. While the Zenbook Duo 14 is suitable for moderate tasks, the Legion 9i's superior GPU and screen attributes make it exceptional for heavy gaming and 3D rendering.

The Lenovo Legion 9i is best in class for engineering and design, while the ASUS Zenbook Duo 14 is only fair.
The ASUS Zenbook Duo 14, with its satisfactory CPU and GPU, and a good screen, is suitable for engineering and design but might struggle with very intensive tasks, whereas the Lenovo Legion 9i with its superior CPU, significantly better GPU, and exceptional screen quality is better equipped to handle demanding engineering and design workloads. The Lenovo's advantages come at the cost of less portability and potentially higher operating noise, which could be important factors for some users.

The Lenovo Legion 9i has a better screen than the ASUS Zenbook Duo 14 for general use, gaming and AI, engineering and design, content creation, and software development.
The ASUS Zenbook Duo 14 offers solid resolution and brightness, making it suitable for general use and detailed engineering or design work where accurate color representation is important. However, with a lower refresh rate, it's less suitable for 3D applications and gaming where smoother motion is key. Meanwhile, the Lenovo Legion 9i excels with exceptional color accuracy and superior resolution and brightness for both general use and professional design tasks, yet like the Zenbook, it falls short for gaming due to a less optimal refresh rate.

"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 9i is meant as a top-end flagship showcase for enthusiasts, and on that, it delivers. You'll find flashier designs in this price tier—Razer’s all-metal build in a similarly sized laptop like the Blade 16, or monstrous 18-inch machines—but this is a well-thought-out laptop. The chassis is trim for a 16-inch powerhouse, the lid is unique, and bespoke liquid cooling takes performance to the next level."
