The ASUS ROG Zephyrus G15 offers better performance with a more powerful processor and graphics card than the Gigabyte A7, making it a better choice for intensive activities like 3D rendering, machine learning, and engineering tasks and also has a higher refresh rate which is great for gaming. It's also more portable and has a longer battery life, which can be an advantage if you move around often. However, it is more expensive. On the other hand, the Gigabyte A7 has a larger screen, which might be better for productivity and entertainment, and it is less expensive, but it doesn't match the G15's performance, battery life, or portability.

"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."

"In terms of looks, the Gigabyte A7 X1 is certainly not a trendy, slim, and ultra-mobile gaming laptop. But it does what it's supposed to do, namely bringing games smoothly onto the screen, very well. Both the processor and the GeForce RTX 3070 are able to unleash their performance without restrictions thanks to the well-ventilated case. The Gigabyte A7 X1 brings modern games smoothly onto the screen and offers excellent maintenance options."
