For better performance in 3D, machine learning, or engineering tasks, along with a larger, brighter display with higher resolution and color accuracy, the Asus Zenbook Pro 16X is a solid choice. However, it's heavier, which compromises portability compared to the portable and lighter Lenovo Slim Pro 9i. The Lenovo boasts more RAM, which aids multitasking and complex processing tasks, along with a higher refresh rate display for smoother visuals. Its battery capacity is lower than the Asus, so it may not last as long on a single charge, but it has a superior portability score, making it a more travel-friendly option. Both laptops are premium models with similar price ranges and are suitable for intensive tasks, but your decision will weigh heavily on performance requirements vs. portability and battery life preferences.

Marc Herter, Alex Wätzel | November 2023
"The new Zenbook Pro 16X is more powerful, quieter and doesn't need to shy away from dedicated workstations and gamers. It is also comparatively compact, and our test device is the best Zenbook that we've reviewed so far. It seems equally suitable for content creators and gamers or anyone looking for a very powerful laptop that is still slim."

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."
