The ASUS Zenbook Pro 17 offers a larger display and higher battery capacity, which may appeal to those seeking more screen real estate and longer battery life, but be aware of its larger size and weight that reduce portability. Meanwhile, the Lenovo Slim Pro 9i features a higher resolution and brighter touchscreen display with better color accuracy that creatives may prefer, and its lighter weight enhances portability. 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

Matthew S. Smith | August 2023
"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."
