For better performance in 3D, machine learning, or engineering tasks, along with a larger, brighter display with higher resolution and color accuracy, the Asus Zenbook Pro 16X is a solid choice. However, it's heavier, which compromises portability compared to the portable and lighter Lenovo Slim Pro 9i. The Lenovo boasts more RAM, which aids multitasking and complex processing tasks, along with a higher refresh rate display for smoother visuals. Its battery capacity is lower than the Asus, so it may not last as long on a single charge, but it has a superior portability score, making it a more travel-friendly option. Both laptops are premium models with similar price ranges and are suitable for intensive tasks, but your decision will weigh heavily on performance requirements vs. portability and battery life preferences.

For general use, the Lenovo Slim Pro 9i excels with a screen that boasts higher resolution and brightness, making everyday tasks like browsing and video streaming a visually pleasant experience. Engineers and designers will appreciate the Slim Pro 9i's superior color accuracy and wider color gamut coverage, ensuring that their work appears vivid and true to life. However, both the ASUS Zenbook Pro 16X and the Lenovo Slim Pro 9i lack the high refresh rates desired for smooth 3D rendering or gaming, which could lead to less fluid motion in those applications.

The Lenovo Slim Pro 9i and ASUS Zenbook Pro 16X are both very good for general use.
The ASUS Zenbook Pro 16X excels in general use with a high-resolution OLED screen, significant battery life, and ample performance capabilities thanks to its solid CPU and plenty of RAM, though it's less portable due to its weight. In contrast, the Lenovo Slim Pro 9i pairs a slightly leaner CPU with more RAM, remarkably high screen brightness and colors, and superior portability aided by its lighter weight and smaller screen, but has a shorter battery life.

The Lenovo Slim Pro 9i and ASUS Zenbook Pro 16X are both good for gaming and AI.
The ASUS Zenbook Pro 16X uses the Nvidia RTX 3060 graphics card, providing solid gaming and 3D performance and has a screen refresh rate of 60Hz, which is adequate for many games but not as smooth as higher refresh rates. On the other hand, the Lenovo Slim Pro 9i features a more recent Nvidia RTX 4050 graphics card for potentially better rendering in games and 3D applications, along with a faster screen refresh rate of 165Hz for fluid motion and reduced motion blur during fast-paced scenes.

The Lenovo Slim Pro 9i and ASUS Zenbook Pro 16X are both very good for engineering and design.
The Lenovo Slim Pro 9i excels in engineering and design due to its superior CPU, double the RAM, and a more powerful GPU compared to the ASUS Zenbook Pro 16X, which is also capable but with slightly lower specs in these key areas. Moreover, the Lenovo's higher screen brightness and sharper display enhance visual precision, although it slightly compromises on portability and operating noise compared to the well-balanced Zenbook Pro 16X.

Marc Herter, Alex Wätzel | November 2023
"The new Zenbook Pro 16X is more powerful, quieter and doesn't need to shy away from dedicated workstations and gamers. It is also comparatively compact, and our test device is the best Zenbook that we've reviewed so far. It seems equally suitable for content creators and gamers or anyone looking for a very powerful laptop that is still slim."

"The Lenovo Slim Pro 9i is an impressive laptop with a brilliant Mini-LED display, a powerful 100-watt version of Nvidia RTX 4050 graphics, and excellent connectivity. Having run the Cinebench benchmark again, we were impressed with the CPU performance. That makes the Slim Pro 9i is an easy recommendation, especially for those who care about GPU and CPU performance. It’s also a fantastic choice if you frequently view HDR movies and games on your laptop."
