For general use, the Lenovo IdeaPad Slim 3 is a more budget-friendly option and provides ample performance for everyday tasks, along with decent portability and battery life. However, if you require higher performance for tasks like 3D rendering, engineering, and machine learning, consider the Razer Book 13, despite its higher price. The Razer Book 13 offers better screen resolution and color accuracy, additional memory, and a superior processor, which makes it well-suited for more demanding applications and multitasking. The Razer Book also has a more premium build, is lighter for enhanced portability, and offers longer battery life, albeit at a higher cost. Give Feedback

The Razer Book 13 has a better screen than the Lenovo IdeaPad Slim 3 for general use, gaming and AI, engineering and design, content creation, and software development.
When considering general use, the Razer Book 13 outshines the Lenovo IdeaPad Slim 3 due to its superior panel quality, higher resolution, and better brightness, leading to a more vivid and clearer display. For engineering and design applications, the Razer Book 13 also takes the lead with its wider color gamut, which results in more accurate color representations that professionals need. However, for Gaming and 3D applications, both laptops are less suitable as their lower refresh rates do not match the high refresh rate demands of these fields, which can compromise smoothness and responsiveness in fast-paced visual content.

Although they have very similar scores, PerfectRec considers Razer Book 13 to be only fair for gaming and AI, while the Lenovo IdeaPad Slim 3 is poor.
The Lenovo IdeaPad Slim 3, equipped with an integrated AMD GPU suitable for lighter gaming, offers a typical screen refresh rate for non-intense gameplay, while the Razer Book 13 includes an Intel Iris Xe GPU, also tailored for casual gaming, but with a higher-quality screen that may offer a slightly better visual experience. Both laptops do not prioritize high-end gaming hardware, which is why they are classified as 'fair' for gaming and 3D tasks.

Olivier Martin, Ryan Lim, and John Peroramas | May 2023
"The Lenovo IdeaPad 3i is decent for use as a workstation. Its Intel CPU and integrated graphics can only handle light productivity tasks, not demanding workloads like video editing or 3D graphics. You also can't do any color-critical work because the available displays have a narrow color gamut. It has a good port selection, but its USB-C lacks Thunderbolt 4 support. On the upside, it has a comfortable keyboard and doesn't get hot or loud under load."

"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."
