Considering the ASUS Vivobook 17 is much less expensive and boasts a larger screen, it's suitable for basic tasks and general usage with moderate battery life. It's also quite portable. On the other hand, the Lenovo Legion 9i, while much more expensive, offers significantly better performance for 3D rendering, machine learning, gaming, and intensive engineering work, accompanied by a higher quality display and superior build. However, it's heavier and less portable with a noticeably shorter battery life, making it less ideal for frequent travel or long periods away from power sources. Choose the ASUS Vivobook 17 for cost-effectiveness and everyday tasks, or the Lenovo Legion 9i for high-performance needs despite its higher cost and lower portability. Give Feedback

The Lenovo Legion 9i is very good for general use, while the ASUS Vivobook 17 is good.
The ASUS Vivobook 17 offers modest CPU and RAM, making it adequate for everyday tasks, though its inferior screen quality, shorter battery life, and slightly better portability may limit its appeal for more demanding general use compared to the Lenovo Legion 9i, which boasts a powerful CPU, ample RAM, and a superior screen, but is less portable and has a shorter battery life for typical use.

The Lenovo Legion 9i is excellent for gaming and AI, while the ASUS Vivobook 17 is only fair.
The Lenovo Legion 9i excels in gaming and 3D tasks largely because it features a high-performance Nvidia RTX 4080 GPU and a high refresh rate Mini LED screen, which are very important for smooth and visually detailed gaming experiences. In comparison, the ASUS Vivobook 17 is only considered fair in this regard due to its modest integrated Intel graphics and a lower refresh rate IPS screen, which may not deliver the same level of graphic intensity or fluid motion in games.

The Lenovo Legion 9i is best in class for engineering and design, while the ASUS Vivobook 17 is only fair.
The Lenovo Legion 9i stands out for engineering and design due to its robust Intel i9 processor, abundant RAM, and high-performance Nvidia RTX 4080 GPU, all of which are essential for intensive tasks, complemented by a superior Mini LED screen that offers crisp image quality and a wide color range. In contrast, the ASUS Vivobook 17 has a more modest Intel i3 processor, less RAM, and a basic integrated GPU, which can still handle engineering work but not as efficiently, and while it has a larger screen, the overall screen quality and color accuracy are lower compared to the Legion 9i.

The Lenovo Legion 9i has a better screen than the ASUS Vivobook 17 for general use, gaming and AI, engineering and design, content creation, and software development.
The ASUS Vivobook 17, while adequate for everyday tasks due to its decent resolution and brightness, may fall short for engineering and design pursuits where accurate color representation is critical, and it lacks in gaming because it doesn't support high refresh rates essential for smooth visuals. The Lenovo Legion 9i stands out with a superior display that offers both high resolution and brightness which enhances general use, and its wide color gamut satisfies the precision needed for engineering and design; however, despite its excellent panel quality, it's not optimized for gaming due to a lower refresh rate. Hence, users prioritize general productivity or professional creative work over gaming may find the Lenovo Legion 9i more appealing, whereas gamers would need to look elsewhere for a display that can keep up with fast-paced action.

"The ASUS Vivobook 17 is an affordable 17-inch laptop with passive cooling. On one hand, you get a really quiet and cool work device with a good system performance, many connections, good maintenance options, speakers acceptable for multimedia enjoyment, and a sharp and clear matte FHD IPS display with the Asus VivoBook 17 (F712JA). On the other hand, the USB-C port lacks Power Delivery and DisplayPort, and the display, a higher brightness and better color space coverage."
"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."
