If you need a laptop with top-tier performance for 3D rendering, machine learning, or engineering tasks, the ASUS ZenBook Pro Duo 15 offers more power and a higher quality screen, but it's heavier and has a shorter battery life compared to the Razer Book 13. Conversely, the Razer Book 13 provides better portability, longer battery life, and is less expensive, making it a strong candidate for general use, though it may struggle with more intensive tasks due to its less powerful processor and integrated graphics. Both have high-quality keyboards and touchscreens, but the ASUS stands out for creative tasks with its dual-screen design and superior color accuracy. Give Feedback

Jared Newman | August 2021
"Benchmarks aside, the Asus ZenBook Pro Duo is hard to compare with other PCs. Its closest competition may be a multi-monitor desktop, or a laptop with an attached travel monitor. The Pro Duo is more portable and versatile than either of those options, especially with the software tools Asus has thrown on top. For a certain niche of artists, media creators, and gamers, all that might add up to something special, even if it’s unattainable for the rest of us."

"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."
