If you prioritize performance for tasks such as 3D modeling, machine learning, or gaming, the Lenovo Legion Slim 7 is better equipped with a higher-grade processor and advanced graphics card, plus it has more RAM and storage. However, it's also heavier and more expensive. The ASUS Vivobook 15X, on the other hand, is more affordable, lighter, and has sufficient capabilities for general use or mid-range tasks, but it won't perform as well with very demanding applications. Battery life is also a consideration, with the Lenovo offering more battery capacity, which could translate to longer use between charges depending on the tasks. Both have solid build quality and come with Windows 11, but if portability is a concern, the ASUS might be the more convenient choice. Give Feedback

The Lenovo Legion Slim 7 16" is very good for general use, while the ASUS Vivobook 15X is good.
The ASUS Vivobook 15X is adequate for general use with a modest AMD Ryzen 5 processor, adequate memory, and storage for basic tasks, but its average screen quality, portability, and battery life might not suit those requiring high performance and long usage times on the go. In contrast, the Lenovo Legion Slim 7 excels in general use with a more powerful AMD Ryzen 7 processor, double the memory for smoother multitasking, and a high-quality screen, which, along with better battery life and portability, provides an overall superior experience for demanding users.

The Lenovo Legion Slim 7 16" is very good for gaming and AI, while the ASUS Vivobook 15X is only fair.
The Lenovo Legion Slim 7 with its Nvidia RTX 4060 graphics card and a high screen refresh rate excels in gaming and 3D tasks, whereas the ASUS Vivobook 15X with its AMD Ryzen 5 7530U Vega 7 graphics and standard refresh rate is less suited for these demanding activities. Additionally, the Legion's superior CPU and screen quality contribute to a much smoother and visually richer gaming experience.

The Lenovo Legion Slim 7 16" is very good for engineering and design, while the ASUS Vivobook 15X is only fair.
The Lenovo Legion Slim 7 16" outshines the ASUS Vivobook 15X for engineering and design use due to its more powerful CPU, double the RAM, advanced graphics card, and higher-resolution screen that renders better visual detail, color accuracy, and brightness, essential for intensive design tasks. While both are portable, the ASUS model is slightly lighter and thinner, but with lower portability due to lesser battery life, whereas the Lenovo offers more power and better screen attributes with a marginal increase in weight and size, making it more suitable for demanding engineering applications.

The Lenovo Legion Slim 7 has a better screen than the ASUS Vivobook 15X for general use, gaming and AI, engineering and design, content creation, and software development.
The ASUS Vivobook 15X's screen may lack the sharpness and color accuracy required for intricate engineering work and its lower refresh rate might not suit fast-paced gaming, but it's bright and clear enough for browsing, writing, and everyday tasks. In contrast, the Lenovo Legion Slim 7 16" offers superior color accuracy and resolution, making it excellent for engineering and design professionals who depend on precise colors and clear details, though its refresh rate isn't the best for high-end gaming. Neither laptop, however, is optimal for gaming and 3D modeling that demand high refresh rates for smoother motion and transitions.

"All in all, my day on the Vivobook had its ups and downs. It is a really pretty and well-built device, and it had all of the functionality I needed to get me through my browser-based workload. But the speakers weren’t my favorite, and the battery life was just too short."
"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
