The ASUS ROG Zephyrus G15 is better suited for intensive tasks such as 3D rendering, machine learning, and gaming due to its more powerful processor and dedicated NVIDIA RTX graphics. However, it's heavier and not as easy to carry around as the ASUS Zenbook 13. The Zenbook 13, with its OLED display, offers better colors and is more portable with a longer battery life, making it a better option for general use and travel. If your primary use is for engineering or gaming and you don't mind the extra weight and cost, go for the Zephyrus G15. But if you prioritize portability, screen quality for general purposes, and a lower price, the Zenbook 13 would be the better option. Give Feedback

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 Asus ZenBook 13 is a compact 13-inch laptop with a fast Ryzen 7 5800U and OLED display. The subnotebook is also light and the modern design is convincing. The selection of high-quality materials make the device not only light, but also very stable. In addition, the visuals and haptics of the device offers a high-quality impression. The AMD Ryzen 7 5800U is a very good fit for the ZenBook 13, ensuring a high performance in the test. However, in terms of the 3D performance, we also notice that the Vega architecture is beginning to hit its limits."
