If you prioritize gaming or need a laptop capable of handling more resource-intensive engineering tasks, the Lenovo Legion Slim 5 with its Nvidia RTX 4060 graphics card is a reliable pick, but it is heavier and has a shorter battery life than its competitor. The Razer Book 13, on the other hand, offers better portability due to its lighter weight and longer battery life, as well as a higher resolution and touchscreen display, making it suitable for general use and 3D rendering tasks, yet its integrated Intel graphics may not be as powerful for heavy gaming or complex engineering software.

The Lenovo Legion Slim 5 has a better screen than the Razer Book 13 for gaming and AI, while the Razer Book 13 has a better screen for general use, and engineering and design.
For general use, the Lenovo Legion Slim 5 and Razer Book 13 both offer displays with ample resolution and brightness, making text sharp and content vibrant, but their conventional panel types may not be as color-accurate as professional-grade monitors. In engineering and design tasks, these laptops can adequately reproduce a wide range of colors with decent color gamut coverage, but professionals requiring the highest color fidelity might find them lacking. However, for gaming and 3D applications where fast motion is common, the lower refresh rates of these screens can result in less smooth transitions compared to displays specifically designed for gaming, which often feature higher refresh rates.

Mark Knapp | August 2023
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."

"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."
