The ASUS Zenbook Duo 14 is a more cost-effective option, typically less expensive than the Razer Book 13, and includes a second screen for multitasking. It's slightly heavier with a larger footprint, and while it has a good battery life, the Razer Book 13 excels with notably longer battery life, making it more suitable for on-the-go use. Furthermore, the Razer Book offers more RAM for better multitasking and a slightly higher screen resolution due to its 16:10 aspect ratio which could be beneficial for reading and productivity tasks. The Razer Book's portability is underscored with a higher portability score and it also has a backlit keyboard with RGB lighting compared to the white backlighting on the ASUS. Both laptops are equipped with similar CPUs and integrated graphics, suitable for general use and some engineering applications, but not ideal for intensive gaming. If budget is a concern and you value innovative features like a second screen, the ASUS Zenbook Duo 14 is considerable, but if you seek longer battery life, more RAM, and better portability, the Razer Book 13 could be worth the extra expense.

The Razer Book 13 has a better screen than the ASUS Zenbook Duo 14 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, the ASUS Zenbook Duo 14 and Razer Book 13 provide crisp and vibrant displays with sufficient brightness and high resolutions that offer sharp text and images, while their panel types contribute to wide viewing angles and consistent colors.

The Razer Book 13 and ASUS Zenbook Duo 14 are both only fair for gaming and AI.
For gaming and 3D tasks, the ASUS Zenbook Duo 14 and the Razer Book 13 both have integrated graphics (Iris Xe from Intel) which offers limited performance compared to dedicated gaming GPUs, and both have a screen refresh rate of 60Hz, which is adequate for casual gaming but may not be the best for fast-paced competitive games where higher refresh rates are preferable.

Although they have very similar scores, PerfectRec considers Razer Book 13 to be good for engineering and design, while the ASUS Zenbook Duo 14 is only fair.
The ASUS Zenbook Duo 14, with its high-definition touch-enabled IPS screen and dedicated graphics, caters to design applications but has less RAM which could limit its multitasking capabilities in engineering software, whereas the Razer Book 13, though smaller and more portable, offers more RAM for complex tasks despite its slightly lower screen resolution and contrast. Regarding CPU and GPU, both are equipped with strong processors and Intel Iris Xe graphics, making them capable for engineering and design, yet the Razer stands out with a better screen brightness and a higher portability score, whereas the ASUS includes a secondary screen that may enhance productivity for design tasks.

"The Asus ZenBook Duo's second screen is like the Apple Touch Bar, but better. Most would agree that having two screens instead of one can really boost productivity and the ZenBook Duo is no different in this regard. It's tough going back to just one screen after becoming accustomed to spacious dual-screen setups. For a laptop form factor, however, users will have to accept some compromises. Firstly, weight is the most obvious drawback as the system is several hundred grams heavier than a regular ZenBook 14. Additionally, colors on the second screen will not be as vivid as the main display."

"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."
