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."

"Our test configuration of the Blade 17 targets gamers and creative professionals. A Core i9-12900H processor, GeForce RTX 3080 Ti Laptop GPU (175 watts TGP after the BIOS update, 16 GB of VRAM), and 32 GB of working memory equip the laptop for video processing, rending, and 4k gaming at the highest level. In addition, a fast PCIe-4 SSD (1 TB) ensures short load and storage times. With the Blade 17 (Early 2022), Razer delivers a successful and powerful work device for creative professionals. But this also has its price."
