Choosing between the ASUS ROG Strix G18 and the Lenovo Legion 7 depends on the preference for either higher performance or better portability. The ASUS offers top-tier performance, suitable for the most intensive gaming, 3D rendering, and engineering tasks, thanks to its high-end processor and GPU. However, it's heavier and has a shorter battery life, which affects portability. In contrast, the Lenovo is less expensive, lighter, and has longer battery life, making it more portable but less powerful for demanding tasks. Both laptops have enough storage and RAM for general use and share similar screen size and resolution, but the ASUS has a higher refresh rate, offering smoother visuals. Give Feedback

The ASUS ROG Strix G18 has a better screen than the Lenovo Legion 7 for general use, gaming and AI, engineering and design, software development, and content creation.
For general use and engineering tasks, both the ASUS ROG Strix G18 and the Lenovo Legion 7 boast high-resolution displays that offer sharp images and accurate colors, ensuring detailed visuals and a wide color spectrum that is crucial for precise design work. However, both models fall short for gaming and 3D applications because of lower refresh rates, which can lead to less smooth visual experiences during fast-paced scenes or when rendering movements. The trade-off is that while these laptops excel in visual fidelity for professional and everyday tasks, they may not satisfy users who prioritize the immersive and fluid gameplay that higher refresh rates provide.

How the ASUS ROG Strix G18 and the Lenovo Legion 7 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."
"The Lenovo Legion 7 is a fast 16-inch gamer with 165 Hz display. The new Lenovo Legion 7 is a very good gaming notebook that, despite its comparatively compact compact 16-inch case, does not have to do without the most powerful components. Thanks to good cooling, no compromises are made in terms of performance. Both the Core i9-12900HX and the GeForce RTX 3080 Ti perform at a very high level."
