The Lenovo Legion 5 Pro offers a robust AMD Ryzen CPU and RTX 4070 graphics, making it suitable for intensive gaming and demanding engineering applications, but it's heavier, which affects portability, and has a lower battery life. On the other hand, the Lenovo Slim Pro 9i, with its Intel i7 processor, slightly less powerful RTX 4050 graphics, and high-resolution Mini LED touchscreen, is well-suited for general use and engineering tasks, featuring a lighter build and better battery life, enhancing its portability. Choose the Legion 5 Pro if performance in gaming and heavy computational tasks is a priority, or the Slim Pro 9i for portability and all-around use with a premium display. Give Feedback

Mark Knapp | July 2023
"It doesn't quite match its Legion Pro 7i sibling as an Editors' Choice winner, but Lenovo's AMD-powered Legion Pro 5 Gen 8 is a stylish, well-built gaming laptop with solid performance at both 1080p and its sharper native resolution. It's cheaper than some comparably equipped machines and better than some similarly priced ones. That's a recipe for success, even without its frequent availability of discounts or sales. A brighter screen and longer battery life would be nice, but even as is the Legion Pro 5 earns a solid recommendation."

"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."
