If you need high performance for intensive 3D modeling, machine learning, or gaming, the Lenovo Legion 9i with its powerful processor and graphics card is excellent, but comes at a higher cost and is heavier, making it less portable. The Lenovo Slim Pro 9i is more affordable and lightweight with a touch screen, suitable for general use and casual gaming, offering better battery life and ease of carrying around. However, it has a less powerful processor and graphics card which might not be suitable for the most demanding tasks. Both have great keyboards, but Legion's is more gaming-oriented while Slim's is ideal for general use. Give Feedback

Matthew Buzzi | December 2023
"The Lenovo Legion 9i is meant as a top-end flagship showcase for enthusiasts, and on that, it delivers. You'll find flashier designs in this price tier—Razer’s all-metal build in a similarly sized laptop like the Blade 16, or monstrous 18-inch machines—but this is a well-thought-out laptop. The chassis is trim for a 16-inch powerhouse, the lid is unique, and bespoke liquid cooling takes performance to the next level."

"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."
