The ASUS ROG Zephyrus G15 is good for gaming and AI, while the Dell Inspiron 16 5620 is only fair.
The ASUS ROG Zephyrus G15 is better suited for gaming and 3D tasks owing to its powerful Nvidia RTX 3070 GPU and a high screen refresh rate of 165Hz, which are very important for smooth graphics and responsive gameplay. In contrast, the Dell Inspiron 16 5620 has a more modest Intel Iris Xe GPU and a 60Hz screen refresh rate, making it adequate for lighter gaming and less demanding 3D applications, but it won't provide the same level of performance or visual fluidity as the ASUS.

The ASUS ROG Zephyrus G15 is very good for engineering and design, while the Dell Inspiron 16 5620 is good.
The ASUS ROG Zephyrus G15 outshines the Dell Inspiron 16 5620 for engineering and design due to its superior CPU, RAM configurations, and GPU, which translates into better processing power and graphical performance essential for demanding applications; it also has a higher quality screen with better resolution, color accuracy, and refresh rate. Although the Dell Inspiron is comparable in RAM and has a good screen for design tasks, its integrated GPU is less powerful than the dedicated one in the ASUS, making it less suitable for graphics-intensive engineering work; however, the Dell is slightly more portable and operates quieter, which could be beneficial for extended use in quieter environments.

How the ASUS ROG Zephyrus G15 and the Dell Inspiron 16 5620 compare to other laptops
"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."
"If the world is exciting enough right now, you can do far worse than a solid performer that you know will get the job done. Our review model is as powerful as you'd want an office machine to be unless you're performing specialist tasks and the price point is pretty attractive (unless work will let you have a MacBook Air instead)."
