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."

Christian Hintze | March 2023
"The MSI Katana 15 B12 combines a Gen12 CPU with an RTX 4050, which is actually not a bad idea for a budget gamer. The CPU is anything but bad and the GPU in the Katana 15 proves to be significantly more efficient than last year's models. However, our main point of criticism for budget gamers is the price: while you can get budget laptops with RTX 3060 from around US$800, you pay a whole US$1,499.99 here! The efficiency advantages of the RTX 4050 do not justify this price premium."
