In choosing between the ASUS ROG Zephyrus M16 and the Lenovo Slim Pro 9i, consider that the ASUS model comes with a higher-end graphics card and a larger 16-inch display, making it more suitable for intensive engineering tasks or gaming. It's slightly heavier and offers a variety of ports. The Lenovo, on the other hand, is lighter and more portable, with a smaller 14.5-inch Mini LED display, which produces better colors, and it has a longer battery life. The Lenovo also offers more RAM, which is beneficial for multitasking and demanding applications. If portability and display quality are your main concerns, go for the Lenovo, but for higher performance in tasks like 3D modeling or gaming, the ASUS would serve you better even though it's less portable.

Christian Hintze | March 2023
"The ASUS ROG Zephyrus M16 is not yet as optimised as its predecessor. Compared to the previous gen, performance and efficiency have improved significantly. What's more, the wonderful, Mini-LED Nebula display is a contender for the main highlight and almost manages to put the CPU and GPU in the shade. We already found its predecessor to be a well-rounded and well-optimised gaming machine. Generally, but not unequivocally, that also applies to the new Asus M16. Similar to most of the current, new laptops, we are dealing with a double generational leap in terms of the CPU and GPU. However, this change doesn't always run smoothly."

"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."
