The ASUS ROG Strix G15 offers good performance and gaming capabilities at a slightly lower price, but with shorter battery life and lower screen resolution than the Zephyrus G15. On the other hand, the ASUS ROG Zephyrus G15, while slightly more expensive, provides a higher-resolution display, better color accuracy, longer battery life, and superior graphics performance courtesy of a more powerful GPU. Therefore, if budget is a concern and you're looking for cost-effectiveness with reasonable performance, the Strix G15 is a viable option. However, for those seeking the best visual experience and extended usage without charging, the Zephyrus G15 could be the preferable choice, especially for intensive tasks like 3D rendering or engineering applications.

Marius Schell | February 2021
"The ASUS ROG Strix G15 is a successful high-performance 15-inch laptop. The Asus ROG Strix impresses with an elaborate design and fast hardware. The latter can unleash its potential well in the large 15-inch case and achieve a decent performance boost compared to the previous generation. Especially the stunning 300 Hz display as well as the RTX 3070 and its generous TDP give gamers their money's worth. Asus didn't neglect seemingly small details, either, such as the keyboard and the maintenance options. The ROG Strix G15 offers a lot of pure performance and excellent workmanship in a 15-inch format, but connectivity leaves something to be desired."

"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."
