The Lenovo Slim Pro 9i is good for gaming and AI, while the ASUS Zenbook 14X is only fair.
The Lenovo Slim Pro 9i outperforms the ASUS Zenbook 14X in gaming and 3D tasks mainly because it features a more powerful Nvidia RTX 4050 graphics card and a higher screen refresh rate. In contrast, the ASUS Zenbook comes with a less capable Nvidia MX550 GPU and a lower refresh rate, which are sufficient for moderate use but not optimal for demanding gaming and 3D applications.

The Lenovo Slim Pro 9i has a better screen than the ASUS Zenbook 14X for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, where clarity, sharpness, and vibrant displays matter, the Lenovo Slim Pro 9i likely offers a higher resolution and brighter screen, making everyday tasks and media consumption more enjoyable. In the context of engineering and design work, the importance of accurate colors to match real-world hues means the Lenovo's superior color gamut coverage can ensure more precise visual representations. However, for gaming and 3D applications which benefit from smoother motion and rapid visual updates, both the ASUS Zenbook 14X and the Lenovo Slim Pro 9i may fall short, as their screens prioritize resolution and color accuracy over higher refresh rates necessary for a fluid gaming experience.

How the ASUS Zenbook 14X and the Lenovo Slim Pro 9i compare to other laptops
"With the Zenbook 14X, Asus has a 14-incher in its range that is - mostly - a joy to use. First, there is the colorful OLED panel with 3K resolution that displays the sRGB and DCI-P3 color spaces. The Zenbook is also at the forefront in terms of workmanship, input devices and connections with 2x Thunderbolt 4 ports and a generous keyboard layout. A pleasure to use, the Zenbook 14X is a solid, very well-built subnotebook that sits well on the table. A runtime of five hours, however, is below average for a high-end subnotebook nowadays. The OLED screensaver causes increased power consumption when in idle mode."
"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."
