The Lenovo Slim Pro 9i is very good for general use, while the Razer Book 13 is good.
The Lenovo Slim Pro 9i excels in general use due to a stronger CPU and more RAM, which translates to faster performance and better multitasking capabilities; it also has a higher resolution and brighter Mini LED screen for superior visual quality but is less portable and has a shorter battery life compared to the Razer Book 13. The Razer Book 13, while still good for general use, offers greater portability with its lighter weight and longer battery life, along with a quality IPS screen, though it has a less powerful CPU and half the RAM, which may affect performance in demanding tasks.

The Lenovo Slim Pro 9i is good for gaming and AI, while the Razer Book 13 is only fair.
The Lenovo Slim Pro 9i excels in gaming and 3D applications because it is equipped with a powerful Nvidia RTX 4050 graphics card and a high refresh rate Mini LED screen. In contrast, the Razer Book 13 has less gaming performance due to its integrated Intel Iris Xe graphics and a standard refresh rate IPS screen, but may offer better battery life and portability.

The Lenovo Slim Pro 9i is very good for engineering and design, while the Razer Book 13 is good.
The Lenovo Slim Pro 9i stands out for engineering and design due to its robust CPU, high RAM, dedicated GPU, and superior screen quality, which are crucial for running resource-intensive applications smoothly and displaying detailed visuals. On the other hand, the Razer Book 13, while still capable for such tasks, offers less powerful CPU and GPU, half the RAM, and a lower quality screen, but compensates with better portability due to its lighter weight and longer battery life.

The Lenovo Slim Pro 9i has a better screen than the Razer Book 13 for general use, gaming and AI, engineering and design, software development, and content creation.
The Lenovo Slim Pro 9i shines in screen quality for general use and engineering due to its high resolution and bright display that accurately reproduces colors, fitting for tasks that require color precision like photo editing and graphic design. For gaming and 3D, however, its screen falls short because it lacks a high refresh rate, which is crucial for smooth motion rendering in fast-paced environments. The Razer Book 13 offers a similar balance, with good color accuracy and resolution for both everyday tasks and technical work, but it is also not equipped for gaming or 3D applications due to a refresh rate that isn't high enough for optimal gaming performance.

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."

"The Razer Book is like an XPS 13, but faster. The Book 13 combines the design philosophy and performance of a Blade Stealth with the 16:10 display of a Dell XPS 13 for an impressive piece of hardware. Office users who want something more stylish than the typical Dell, HP or Lenovo will certainly find themselves drawn to this Razer subnotebook. If your priorities are to have the best-looking and fastest 13-inch laptop in the office over auxiliary features, however, then the Book 13 proudly fulfills that niche."
