For demanding tasks like 3D design, gaming, or machine learning, the more expensive Asus offers better performance, but it's heavier which makes it less convenient to carry around. On the other hand, the Lenovo is more affordable and portable, with enough capability for general use and lightweight engineering, plus likely a longer battery life. If your work involves intensive applications or you're an avid gamer, investing in the Asus pays off in power, but for everyday tasks and greater mobility, the more budget-friendly Lenovo should suffice.

The ASUS ROG Strix G18 is very good for gaming and AI, while the Lenovo ThinkBook 13x is only fair.
The ASUS ROG Strix G18 typically comes with a powerful GPU and a high screen refresh rate, making it excellent for gaming and 3D applications; it's designed to handle visually intensive tasks smoothly. In contrast, the Lenovo ThinkBook 13x generally offers a less powerful GPU and a lower screen refresh rate, so it's adequate but not optimal for such activities, although it may have a good CPU and screen quality for everyday tasks.

The ASUS ROG Strix G18 has a better screen than the Lenovo ThinkBook 13x for gaming and AI, software development, and content creation.
The ASUS ROG Strix G18 and Lenovo ThinkBook 13x have high-resolution displays with bright panels that make text and images sharp and clear, ideal for everyday tasks like browsing and watching videos, thus ensuring a satisfying general use experience. Both laptops cover a wide range of colors, satisfying the demands of engineering and design professionals who need accurate color representation for tasks like photo editing or CAD work. However, for gaming and 3D applications where smooth motion is key, both models fall short due to lower refresh rates, meaning fast-paced visuals may not appear as smooth as on displays specifically designed for those activities.

Florian Glaser | March 2023
"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."
