The Lenovo Legion 5i Pro offers great value for gaming and engineering tasks due to its powerful processor and high-end graphics card, but it's bulkier and has a shorter battery life, making it less portable. On the other hand, the Lenovo Slim Pro 9i, while more expensive, has a superior display with higher resolution and brightness, a lighter and thinner build for better portability, and a longer battery life, making it a better choice for general use and professional tasks that benefit from high-quality visuals. Both devices have robust performance, but the Slim Pro 9i additionally offers features like a touchscreen and better color accuracy, which are advantageous for creative professionals. Give Feedback

"The midpriced Lenovo Legion Pro 5i Gen 8 follows some of our favorite gaming machines, including last year's model and the higher-end Legion Pro 7i Gen 8 tested earlier this year. But pedigree doesn't count for much in the computer world, and gaming laptops require a certain level of power and graphics performance to justify their prices. The Pro 5i Gen 8 just doesn't do that, offering middling CPU and GPU performance rather than the sort of muscle that would make it a great value."

"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."
