The Lenovo Legion 5 17" offers a larger screen and keyboard with a number pad which is good for productivity, but it's heavier and bulkier, making it less portable. The battery life is on the lower side. If gaming, 3D rendering or machine learning is your priority, its larger screen may offer an enhanced experience. On the other hand, the Lenovo Legion Slim 7 15.6" is much lighter and offers better battery life, making it more suitable for those who frequently carry their laptop around. Although it has a smaller screen, it still maintains powerful performance for gaming and engineering tasks. Both feature similar processors and graphics cards, but the Slim 7 comes with double the storage space. If portability, battery life, and storage are your top concerns, the Slim 7 is the better choice. Give Feedback

Sebastian Bade | February 2022
"The Lenovo Legion 5 17 is a current-gen 17-inch gaming laptop and equipped with the latest AMD CPU and a powerful GPU, that manages to reach its full potential. The AMD Ryzen 5 5600H is a very good choice for this laptop and able to maintain its performance level for long periods of time. Our test model only falls behind consistently in a direct comparison with its competitors that are often equipped with eight cores and 16 threads. Despite this, the Legion 5 17 leaves an excellent impression and is almost able to keep up with an Nvidia GeForce RTX 3070 mobile GPU in synthetic benchmarks."

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."
