The ASUS ROG Strix G15 is less expensive and slightly lighter, making it more portable. It should work well for general use and moderate gaming, but the Strix G18 outperforms it significantly, especially in tasks related to 3D rendering, machine learning, and engineering thanks to a more powerful processor and graphics card. The G18 also offers a larger, higher resolution display, better battery life, and more advanced features like a higher screen refresh rate and improved color coverage, but it's heavier and more costly. Those looking for top performance for demanding applications and gaming, and who don't mind the extra weight and price, may prefer the Strix G18. Give Feedback

The ASUS ROG Strix G18 is very good for engineering and design, while the ASUS ROG Strix G15 is good.
The ASUS ROG Strix G15 is good for engineering and design due to its high-end AMD Ryzen 9 CPU, quality GPU, ample RAM, and decent screen, but the ASUS ROG Strix G18 stands out with its newer and more powerful Intel i9 CPU, superior RTX GPU, and a larger, higher resolution screen that better covers color spaces, making it very good for intensive tasks. While the G18's heavier build and larger form factor detract from portability, it compensates with enhancements in keyboard and speaker quality, alongside a quieter operating noise, which is advantageous for long hours of work.

The ASUS ROG Strix G18 has a better screen than the ASUS ROG Strix G15 for general use, gaming and AI, engineering and design, content creation, and software development.
The ASUS ROG Strix G15 and G18 have panels with high resolution and brightness which are essential for sharp and clear display in general use, while their color accuracy covers a wide spectrum, making them suitable for engineering and design tasks that require true-to-life color representation. However, for gaming and 3D applications where smooth motion is key, the screen's lower refresh rate on both models may not provide the fluid visual experience desired by enthusiasts in those fields. This makes the laptops less ideal for high-speed gaming and 3D rendering which benefit significantly from higher refresh rates for a more immersive experience.

"The ASUS ROG Strix G15 is a successful high-performance 15-inch laptop. The Asus ROG Strix impresses with an elaborate design and fast hardware. The latter can unleash its potential well in the large 15-inch case and achieve a decent performance boost compared to the previous generation. Especially the stunning 300 Hz display as well as the RTX 3070 and its generous TDP give gamers their money's worth. Asus didn't neglect seemingly small details, either, such as the keyboard and the maintenance options. The ROG Strix G15 offers a lot of pure performance and excellent workmanship in a 15-inch format, but connectivity leaves something to be desired."
"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."
