Andreas Osthoff | March 2022
"The Asus ROG Flow Z13 is a gaming tablet with powerful Alder Lake i9 CPU. The ROG Flow Z13 impresses with its good cooling. After our review, the impression is predominantly positive. Besides a very fast Alder Lake CPU and stable gaming performance, especially the cooling system is surprisingly effective and quiet. You can use the integrated speakers without any issues while gaming. The 1200p display in the 16:10 format also impresses with good color reproduction and high brightness. Since the battery runtimes aren't particularly long as it is, we wouldn't recommend the optional 4K panel."

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."
