The Asus ROG Strix Scar 17 X3D is a top-tier gaming laptop with exceptional performance for gaming, 3D rendering, and machine learning tasks, thanks to its powerful Nvidia RTX 4090 GPU and AMD Ryzen 9 7945HX3D processor. It boasts a high-refresh-rate display, making it ideal for fast-paced gaming. However, its larger size and weight make it less portable, and it comes with a high-end price tag. On the other hand, the Lenovo Legion 7 offers a more balanced approach, with a midrange price and solid performance for general use and gaming due to its Nvidia RTX 3070 and AMD Ryzen 7 5800H. It's more compact and lighter, making it a better choice if you need to carry your laptop around frequently. While its performance is not as high as the Asus, it still delivers a great gaming experience and has a beautiful high-resolution display with a taller aspect ratio, which is beneficial for productivity. If portability and cost are important to you and you don't need the absolute best performance for intensive tasks, the Lenovo Legion 7 is a strong contender. However, if you're looking for the ultimate gaming and creative workhorse and don't mind the bulk and higher price, the Asus ROG Strix Scar 17 X3D is the way to go. Give Feedback

Andreas Osthoff | September 2022
"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."
