The Lenovo Legion 9i is more expensive but offers higher performance suitable for intensive gaming, 3D rendering, and other engineering tasks, thanks to its powerful processor and graphics card. It also features a Mini LED display with high brightness and color coverage, but with a larger size and weight, which impacts portability. On the other hand, the Razer Book 13 is lighter and thus more portable, offers a touchscreen, and has a longer battery life for general use, but with less storage and memory, and an integrated graphics card, making it less ideal for demanding tasks. Choose the Legion 9i for performance-centric tasks or the Razer Book for better portability and casual use. Give Feedback

The Lenovo Legion 9i is excellent for gaming and AI, while the Razer Book 13 is only fair.
The Lenovo Legion 9i outperforms the Razer Book 13 in gaming and 3D tasks primarily because it houses a superior Nvidia RTX 4080 GPU and has a higher screen refresh rate of 165 Hz, compared to the Razer's integrated Intel Iris Xe graphics and 60 Hz refresh rate. The Lenovo's GPU enhances complex graphics rendering significantly, and its refresh rate makes on-screen motion smoother, which are crucial for gaming and 3D applications, whereas the Razer's screen quality, while decent, is less suited for those purposes due to its modest hardware.

Matthew Buzzi | December 2023
"The Lenovo Legion 9i is meant as a top-end flagship showcase for enthusiasts, and on that, it delivers. You'll find flashier designs in this price tier—Razer’s all-metal build in a similarly sized laptop like the Blade 16, or monstrous 18-inch machines—but this is a well-thought-out laptop. The chassis is trim for a 16-inch powerhouse, the lid is unique, and bespoke liquid cooling takes performance to the next level."

"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."
