The Lenovo Legion Slim 7 excels in gaming and engineering tasks with its powerful GPU, high refresh rate screen, and exceptional performance in intensive applications, making it suitable for those uses but at a higher price and weight. The LG Ultra 16, on the other hand, offers better battery life and is lighter, enhancing its portability and making it an excellent choice for general use or for professionals who prioritize battery life and mobility over raw performance, and it comes at a lower price point. Both have similar RAM and storage capacities, but the LG's lower performance scores make it less suitable for demanding 3D, machine learning, or engineering tasks. Give Feedback

The Lenovo Legion Slim 7 15.6" is good for gaming and AI, while the LG Ultra 16 is only fair.
The Lenovo Legion Slim 7 is equipped with a Nvidia RTX 3060 GPU and a higher screen refresh rate of 165 Hz, making it a superior choice for gaming and 3D work compared to the LG Ultra 16, which only has an integrated Vega 8 GPU and a standard refresh rate of 60 Hz.

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."

"Unlike the gram, the Ultra PC isn't designed to be as lightweight as possible. The 16-inch laptop is a whole 400 g (0.88 lb) heavier than its 16-inch gram counterpart partly because its chassis is not made of magnesium. Other than that, the Ultra PC seems like a copy of the gram – but with longer battery life, lower noise levels, and a clean, delicate look."
