If you need high performance for tasks like 3D rendering, machine learning or engineering software, the Lenovo Slim Pro 9i with its powerful processor and dedicated graphics card excels; however, it's more expensive and offers less battery life compared to the LG Ultra 16. On the other hand, the LG Ultra 16 is more affordable, has a fanless design for silent operation, offers better battery life, and is slightly lighter, making it ideal for general use and portability. Neither is ideally suited for intensive gaming, despite the Lenovo's better graphics capabilities. Choose based on your main activities: intensive tasks go for the Lenovo; longer battery life and general use, choose the LG. Give Feedback

"The Lenovo Slim Pro 9i is an impressive laptop with a brilliant Mini-LED display, a powerful 100-watt version of Nvidia RTX 4050 graphics, and excellent connectivity. Having run the Cinebench benchmark again, we were impressed with the CPU performance. That makes the Slim Pro 9i is an easy recommendation, especially for those who care about GPU and CPU performance. It’s also a fantastic choice if you frequently view HDR movies and games on your laptop."

"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."
