The ASUS ROG Strix G18 generally costs more and offers better performance for 3D rendering, machine learning, and other intensive tasks due to its more powerful processor and graphics card; it has an RGB backlit keyboard with a number pad and a higher refresh rate display, but it's heavier and less portable. In contrast, the ASUS ROG Zephyrus G15 is usually less expensive, more portable with a better battery life, and has a higher portability score; it's also suitable for various applications including gaming, but its performance in extremely demanding tasks might not match the G18. Consider the Strix G18 if performance is a priority and portability is secondary, or the Zephyrus G15 for a balance of performance, portability, and value. Give Feedback

How the ASUS ROG Strix G18 and the ASUS ROG Zephyrus G15 compare to other laptops
"With the ROG Strix G18, Asus has made an almost consistently good debut in the still quite new 18-inch laptop segment. The base unit case shows a few signs of weakness in the area of stability and is something which has an effect on the perceived quality of the input devices (the chassis tends to rattle a bit). Nevertheless, thanks to generous port features (incl. Thunderbolt 4), a striking design, and extensive lighting (keyboard, LED strip on the front), gamers get a fitting gaming platform."
"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."
