How the Lenovo Legion Pro 5i and the Lenovo Legion Slim 7 15.6" compare to other laptops
"The midpriced Lenovo Legion Pro 5i Gen 8 follows some of our favorite gaming machines, including last year's model and the higher-end Legion Pro 7i Gen 8 tested earlier this year. But pedigree doesn't count for much in the computer world, and gaming laptops require a certain level of power and graphics performance to justify their prices. The Pro 5i Gen 8 just doesn't do that, offering middling CPU and GPU performance rather than the sort of muscle that would make it a great value."
"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."
