The Lenovo IdeaPad Slim 5i is less expensive, has a larger 16-inch screen, and is a beneficial option if you're looking for a budget-friendly laptop with a good-sized display. It comes with an Intel i5 processor, which is suitable for general use. However, the Razer Book 13, while more expensive, offers a more powerful Intel i7 processor, has a smaller and more portable 13.4-inch touchscreen, and boasts better overall build quality. The Razer offers a longer battery life, which, combined with its lighter weight, makes it more suitable for on-the-go use. If you need a laptop for higher-performance tasks or more premium build and features, the Razer Book 13 may be the better choice, but if cost and screen size are your primary concerns, the Lenovo IdeaPad Slim 5i could serve you well for general use and lighter tasks.

The Razer Book 13 has a better screen than the Lenovo IdeaPad Slim 5i for general use, gaming and AI, engineering and design, and software development.
The Lenovo IdeaPad Slim 5i offers a display with adequate resolution and brightness for everyday tasks and clear image quality, making it suitable for general use, but the limited color gamut and standard refresh rate may not satisfy engineering and design professionals who require accurate color reproduction, nor gamers who seek smoother motion. The Razer Book 13, with its higher-quality display, provides stronger color accuracy and vibrancy due to better coverage of professional color spaces, benefiting engineering and design work, but, like the IdeaPad, falls short for gaming due to a refresh rate that's not optimized for fast-paced action. Neither laptop has a high refresh rate panel, which is crucial for the fluid visuals demanded by gaming and some 3D applications, thus making them less ideal for those specific uses.

The Razer Book 13 and Lenovo IdeaPad Slim 5i are both good for general use.
The Lenovo IdeaPad Slim 5i with its capable Intel i5 processor and 16GB of RAM offers reliable performance for general use, matched with a good screen and all-day battery life, while its weight and size maintain portability. The Razer Book 13 steps up with a higher-end Intel i7 processor and a touch display that offers superior color coverage and brightness, appealing to those needing a more powerful and visually detailed experience, along with a lightweight build for greater portability and longer battery life, although it may cost more than the Lenovo.

The Lenovo IdeaPad Slim 5i and Razer Book 13 are both only fair for gaming and AI.
The Lenovo IdeaPad Slim 5i and the Razer Book 13 both have integrated Intel Iris Xe GPUs, which are capable but not optimal for demanding gaming and 3D tasks, and their screens are limited to a 60Hz refresh rate, which is standard for general use but not ideal for high-frame-rate gaming. While the Razer Book 13 comes with a stronger CPU, the i7 compared to the IdeaPad's i5, and higher screen quality, both these factors are only somewhat important and do not compensate for the limitations in GPU and screen refresh rate.

The Razer Book 13 and Lenovo IdeaPad Slim 5i are both good for engineering and design.
The Lenovo IdeaPad Slim 5i and the Razer Book 13 are suited for engineering and design use due to their powerful CPUs, substantial RAM for multitasking, and integrated Iris Xe graphics that can handle light design work. However, the Razer Book 13 offers a higher screen resolution and brightness which is advantageous for design precision, although the IdeaPad Slim 5i's larger screen could be preferred for multitasking and extended work sessions, with both laptops providing high-quality IPS panels and portability, though the Razer Book 13 is lighter and more compact.

"The device is made for average work loads and if your work has a lot to do with online browsing, using apps that are not power-hungry and streaming videos. The looks are really good and the device in itself is not a heavy one. And with Intel 11th-gen Core processor, you might sail through most of your work without complaints."

"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."
