The ASUS ROG Zephyrus G15 offers high performance suitable for intensive gaming, 3D rendering, and machine learning tasks, but it is less portable due to its larger size and higher weight. It has ample storage, a powerful main processor, and a high-end GPU which ensures smooth multitasking and gaming experiences. Conversely, the ASUS Zenbook 14X is more portable owing to its lighter weight and smaller dimensions, making it a better choice for general use and on-the-go productivity. The Zenbook's OLED screen produces excellent colors and contrast, ideal for content creation and consumption, though it has less storage and a less powerful GPU, which may not suit demanding gaming or engineering applications.

Although they have very similar scores, PerfectRec considers ASUS ROG Zephyrus G15 to be very good for engineering and design, while the ASUS Zenbook 14X is good.
The ASUS ROG Zephyrus G15 stands out for engineering and design due to its combo of high-grade CPU, plentiful RAM, robust GPU, and top-tier screen, though it's less portable and noisier; the ASUS Zenbook 14X, while offering solid CPU, ample RAM, decent GPU, and quality screen, scores better in portability and less operational noise, but may not handle intensive tasks as swiftly. Both have commendable keyboards and speakers, but prioritize the Zephyrus for heavy-duty work and the Zenbook for on-the-move usability with less demanding tasks.

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."

"With the Zenbook 14X, Asus has a 14-incher in its range that is - mostly - a joy to use. First, there is the colorful OLED panel with 3K resolution that displays the sRGB and DCI-P3 color spaces. The Zenbook is also at the forefront in terms of workmanship, input devices and connections with 2x Thunderbolt 4 ports and a generous keyboard layout. A pleasure to use, the Zenbook 14X is a solid, very well-built subnotebook that sits well on the table. A runtime of five hours, however, is below average for a high-end subnotebook nowadays. The OLED screensaver causes increased power consumption when in idle mode."
