It also has superior screen technology for fast motion, making it suitable for more intensive gaming. Both laptops are similarly priced, with ample storage and memory, but your choice should consider usage scenarios and the importance of portability versus screen size. Give Feedback

The Lenovo Slim Pro 9i is good for gaming and AI, while the ASUS Zenbook Pro 17 is only fair.
The ASUS Zenbook Pro 17's Nvidia RTX 3050 GPU and average screen refresh rate make it capable for gaming and 3D applications, while the Lenovo Slim Pro 9i offers a superior Nvidia RTX 4050 GPU and a much higher screen refresh rate, providing a smoother and more visually detailed experience for gaming and 3D tasks. Although both have quality screens and capable CPUs, the Lenovo Slim Pro 9i's superior specs in the most important aspects make it stand out for these particular uses.

The Lenovo Slim Pro 9i and ASUS Zenbook Pro 17 are both very good for engineering and design, though the Lenovo Slim Pro 9i is somewhat better.
The Lenovo Slim Pro 9i excels in engineering and design use because it boasts a superior GPU, a high-resolution Mini LED touchscreen, and exceptional contrast ratio catering to detailed and color-sensitive work, despite being less portable due to its smaller screen. In comparison, the ASUS Zenbook Pro 17 offers a large IPS screen which is not as sharp or color-accurate and comes with a less powerful GPU, compromising on peak performance but gaining in portability and a bigger viewable area.

The Lenovo Slim Pro 9i has a better screen than the ASUS Zenbook Pro 17 for general use, gaming and AI, engineering and design, content creation, and software development.
When considering general use, the Lenovo Slim Pro 9i outshines the ASUS Zenbook Pro 17 due to its superior resolution and brightness, which enhance everyday tasks such as browsing, streaming videos, and document editing. For engineering and design professionals who require accurate color representation, the Lenovo Slim Pro 9i excels again with its wide color gamuts, ensuring that designs and visual work appear true to life. However, both laptops offer less than ideal experiences for gaming and 3D applications because they lack high refresh rates, which are critical for smooth, responsive visuals during fast-paced scenes.

"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."
