For general use, the ASUS ZenBook Pro Duo 15 offers higher RAM, an OLED touchscreen, and better color accuracy, making it ideal for content creators needing precise visuals, though it is heavier and less portable than the ASUS ROG Zephyrus G15. The Zephyrus G15, on the other hand, is more suitable for gaming with a higher refresh rate display and efficient heat management, and it provides similar performance for engineering tasks at a slightly lower cost, all in a more portable form. Both laptops have high-end processors and graphics suitable for intensive workloads, but the ZenBook's screen might have less fast motion clarity due to a lower refresh rate. 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."

"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."
