Sascha Mölck | July 2022
"The Asus TUF Dash F15 FX517ZR is a laptop with mobile RTX 3070 and acceptable battery life. The Asus TUF Dash F15 was made for high-performance applications like video editing, rendering, and gaming. The laptop can manage the latter in QHD resolution and at high to maximum settings. However, the focus isn't on maximum performance, but instead, it's about a compromise between performance and portability."

"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."
