The ASUS ROG Zephyrus G15 is more expensive but offers higher performance with better processing power, graphics, and larger storage, suitable for intensive tasks like 3D rendering, engineering work, and gaming. It also has a higher resolution display and longer battery life, making it a strong choice for those needing a powerful machine that's still somewhat portable. On the other hand, the Gigabyte G5 is less expensive and provides good value for everyday use and less demanding games, but it compromises with a lower resolution screen and significantly shorter battery life. If budget is a major concern and your tasks are not as intensive, the Gigabyte G5 could suffice, but for demanding activities and a higher-quality display, the ASUS is the better choice.

The ASUS ROG Zephyrus G15 has a better screen than the Gigabyte G5 for general use, gaming and AI, engineering and design, software development, and content creation.
For general use, the ASUS ROG Zephyrus G15's higher resolution and brighter display make it ideal for crisp text and vibrant images, whereas the Gigabyte G5's adequate but less impressive display translates to serviceable but not exceptional visual clarity. In the realm of engineering and design, the ASUS's superior color coverage ensures more accurate color representation needed for precise work, while the Gigabyte's display, although acceptable, doesn't match up for high fidelity color tasks. When it comes to gaming and 3D applications, the slower refresh rate of the ASUS stifles smooth motion rendering, a strength typically crucial for these fields, whereas the Gigabyte, despite having similar issues, might prove slightly less restrictive due to its display properties.

Although they have very similar scores, PerfectRec considers ASUS ROG Zephyrus G15 to be very good for engineering and design, while the Gigabyte G5 is good.
The ASUS ROG Zephyrus G15 outshines the Gigabyte G5 for engineering and design due to its superior AMD Ryzen 9 CPU, higher RAM, more powerful Nvidia RTX 3070 GPU, and a higher resolution screen with better color coverage, all of which are crucial for demanding tasks and detailed visual work. While both are similar in portability and keyboard quality, the ASUS offers better screen quality and speaker quality, but might produce more operating noise, trade-offs worth considering for professionals needing top performance and display fidelity.

"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 G5 KE is a midrange gaming laptop that checks most boxes. Gigabyte makes good use of the Core i5-12500H and RTX 3060 Laptop GPU combo, and we find no untoward issues with overall performance. The dual-fan quad-heatpipe cooling arrangement does well to ensure that the underlying hardware doesn't throttle under load. That being said, the display is below par when compared to 2023 standards, especially when competing devices."
