The ASUS ROG Flow Z13 is more portable and has a touchscreen with a higher refresh rate, making it suitable for on-the-go use and some gaming. On the other hand, the Gigabyte Aorus 15X offers a larger screen and better battery life, which along with its more powerful graphics, make it a better fit for intensive gaming, heavy 3D rendering, and engineering applications. Both laptops have similar performance for general use, although for tasks that demand high graphical power, the Aorus 15X takes the lead. However, the Aorus 15X is significantly heavier, which could affect its portability. If you prioritize mobility and touchscreen functionality, go with the ASUS. If gaming performance and screen size are more important, and you don't mind the extra weight, the Gigabyte should be your choice. Give Feedback

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."

"The Gigabyte Aorus 15X is a strong showing of Raptor Lake and RTX 4000 series. While the Aorus had trouble keeping up in older games like Grand Theft Auto V, it nudged past the competition in Shadow of the Tomb Raider. It also flexed its next-generation muscle in Far Cry 6 and Borderlands 3. While we were impressed with the overall build quality and design of the Aorus 15X, the keyboard lacked good tactile feedback. The display performed well in real-world testing despite its on-paper shortcoming with brightness, but the speakers are lackluster at best."
