The Lenovo Slim Pro 9i stands out for its higher performance suitable for intensive engineering tasks, 3D rendering, and machine learning thanks to its superior main processor and dedicated GPU. However, it is heavier and has a shorter battery life which affects portability. The LG Gram 16, on the other hand, is lighter, offering excellent portability with a significantly longer battery life, making it ideal for general use and travel. It sacrifices some performance due to its integrated GPU and less powerful processor, making it less suitable for demanding applications. Consider the Lenovo if performance is crucial and the LG Gram if you prioritize portability and longer use on a single charge. Give Feedback

The Lenovo Slim Pro 9i has a better screen than the LG Gram 16 for general use, gaming and AI, engineering and design, software development, and content creation.
If you place a premium on a vibrant display for daily tasks and professional design work, the Lenovo Slim Pro 9i excels due to its high resolution, brightness, and broad color coverage, ensuring everything from text to detailed designs looks crisp and vivid. However, for gamers and 3D artists who require fluid motion, this laptop falls short because it lacks a high refresh rate, vital for smooth, fast-paced visuals. In contrast, the LG Gram 16 offers a balanced experience with respectable general and design performance, albeit it doesn't specially cater to the fast refresh demands of gaming and 3D rendering.

"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."

"The LG Gram 16 is a lightweight device with stability issues. The LG Gram 16Z90Q with a Core i7-1260P is made with portability in mind and places less of a focus on users with high demands on performance. The compact and light chassis is particularly practical when you are on the go. The device is not only comfortably small and lightweight, it also boasts a great battery life. When connected to mains, on the other hand, the 16-inch device is rather disappointing. The standard cooling mode causes extreme volatility in terms of CPU, SSD and iGPU performance. The meager stability of the chassis may also put off some potential buyers."
