If portability is important to you, the ASUS ROG Zephyrus G15 is typically more lightweight and has longer battery life, making it better for on-the-go use. However, if you are more concerned with gaming or doing resource-intensive tasks like 3D rendering or engineering software, the Gigabyte Aorus 15 often has better thermal management and performance, which might extend the laptop's lifespan and improve your experience with demanding applications. Both are well-suited for general use, though the ASUS might have an edge when it comes to keyboard comfort and screen quality. Remember that advances in performance often lead to higher power consumption, which can reduce battery life. 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 Gigabyte Aorus 15 is a power-hungry gaming beast. The Aorus 15 is designed to run games at QHD and high to max settings. But it also cuts a good figure in other demanding applications such as video editing and rendering. This is made possible by the Core i7 12700H and GeForce RTX 3070 Ti Laptop inside the machine. A lightning-fast PCIe 4.0 SSD (1 TB) allows for short loading times."
