The Lenovo IdeaPad Pro 5i offers a balance of cost and capability, with ample storage, solid RAM, and a high-quality processor suitable for general use and gaming. However, its larger size and slightly heavier weight affect portability. The Lenovo Slim Pro 9i stands out with more storage, increased RAM, a more powerful processor, a higher-resolution touch display with better color accuracy, in a thinner and lighter package, benefiting users needing ultimate performance for tasks like 3D rendering or engineering. Both pack a similar battery size, but these features make the Slim Pro 9i more expensive. Consider the IdeaPad Pro 5i for general use and occasional gaming, but choose the Slim Pro 9i if performance and portability are essential, despite the higher cost. Give Feedback

How the Lenovo IdeaPad Pro 5i and the Lenovo Slim Pro 9i compare to other laptops
"Lenovo’s IdeaPad Pro 5i represents an impressive opening salvo for Meteor Lake in the ultraportable space against familiar foes from AMD and Apple. Not only does the Core Ultra 5 125H processor provide good performance across the board, but battery life remains a strong point against the Acer Swift Edge 16 with its AMD Ryzen 7 7840U processor. It can’t quite match the endurance of the 15-inch MacBook Pro, but the gap is shrinking."
"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."
