Christian Hintze | January 2023
"Overall, the all-AMD system in the Alienware m17 R5 is impressive, especially the graphics performance. However, various driver issues and unnecessary inconsistencies prevent us from truly enjoying such a potent gaming machine. In addition to strong 3D performance, we particularly like the build quality, the fairly bright UHD display with high color space coverage, and the fact that the gamer is often quiet when not under load and also rather quieter than some competitors under load."

Benjamin Herzig | November 2022
"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
