The ASUS ROG Zephyrus G15, with a powerful AMD Ryzen processor and Nvidia RTX 3070 graphics, is suited for intensive gaming, 3D rendering, and engineering tasks. It offers a high refresh rate display for smooth visuals, but it is heavier and has a short battery life. The Razer Book 13, on the other hand, is highly portable due to its lighter weight and longer battery life, with a touchscreen and better screen aspect ratio for productivity, but its Intel i7 processor and integrated graphics limit its capacity for demanding gaming or engineering software.

The ASUS ROG Zephyrus G15 has a better screen than the Razer Book 13 for general use, gaming and AI, engineering and design, and content creation.
The ASUS ROG Zephyrus G15 offers a high-resolution display with great brightness and vibrant colors, suiting it for general use and engineering tasks where detail and color accuracy are key. However, its lower refresh rate makes it less optimal for gaming and 3D work, where fluid motion is crucial. The Razer Book 13, while also providing a high-resolution screen with good brightness and color fidelity, falls short for gaming and 3D applications due to a similarly low refresh rate that doesn't support the swift visual feedback required.

Florian Glaser | February 2021
"As long as you're aware of the fact that the GeForce RTX 3080 laptop version can only unfold its potential to a limited extent due to Asus's low TDP setting and that it can be slower than a fast RTX 3070 laptop, the ROG Zephyrus G15 GA503Q cuts a fine figure. One of the biggest highlights turns out to be the WQHD panel, since it attracts customers with 165 Hz, relatively fast response times, FreeSync, and good color-space coverage. Other selling points are the surprisingly rich sound, the long battery life, and the sleek design. In terms of looks, the white edition stands out nicely from the competition."

"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."
