When choosing between the ASUS Zenbook 13 and the Lenovo Slim Pro 9i, consider that the ASUS is less expensive, lighter, and offers longer battery life, making it highly portable and well-suited for general use or work on-the-go. However, if you need top-notch performance for intensive tasks like 3D modeling, machine learning, or gaming, the Lenovo has a much more powerful processor, better graphics, and additional RAM, though it comes with a higher price tag and is heavier, which may affect its portability. The Lenovo also features a higher resolution touchscreen and superior color accuracy, which benefits professional creative work and entertainment, but it has a shorter battery life. Give Feedback

"The Asus ZenBook 13 is a compact 13-inch laptop with a fast Ryzen 7 5800U and OLED display. The subnotebook is also light and the modern design is convincing. The selection of high-quality materials make the device not only light, but also very stable. In addition, the visuals and haptics of the device offers a high-quality impression. The AMD Ryzen 7 5800U is a very good fit for the ZenBook 13, ensuring a high performance in the test. However, in terms of the 3D performance, we also notice that the Vega architecture is beginning to hit its limits."
"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."
